Description

More info for the terms: fruit, root crown, seed, shrub, tree

The following description of pin cherry provides characteristics that may be relevant to fire ecology, and is not meant for identification. Keys for identification are available (e.g. [44,104,115,127]).

Pin cherry is a shrub or small tree [19,63,96,109,127]. It generally has a straight trunk and a narrow, round-topped crown [5,53,59,66,109,127], though it may form thickets [109]. Branches, at first ascending, become more or less horizontal and spreading with age. Pin cherry generally grows 15 to 50 feet (5-15 m) tall and 4 to 20 inches (10-51 cm) in diameter [5,53,59,66,109,127]. However, trees up to 100 feet tall (30 m) have been found in the southern Appalachians [19,53], with the largest size attained on western slopes of the Great Smoky Mountains [53]. In western North America, pin cherry (P. p. var. saximontana) may be generally smaller with an arching shrub form, growing 5 to 15 feet (1.5-4.5 m) tall and spreading 5 to10 feet (1.5-3 m) [23].

Pin cherry has thin foliage [63], with leaves 1.5 to 4.3 inches (4-11 cm) long [59,66,109,127] and 0.5 to 1.75 inches (1-4.5 cm) wide [59,66,127]. Flowers grow in small clusters of 5 to 7 with individual flowers 0.4 inch (1 cm) across. Fruit are drupes 0.15 to 0.3 inch (4-8 mm) across with 1 large seed [19,53,59,66,109,127,143]. Seeds are 0.15 to 0.24 inch (4-6 mm) in diameter with a thick seed coat. There are 13,600 to 22,700 seeds per pound (30,000-50,000 seeds/kg) [19,143].

Pin cherry has a shallow root system [53,143]. In New England, root systems in 4- to 14-year-old stands were less than 14 inches (36 cm) deep and had many lateral branches. In West Virginia, root systems of wind-thrown trees 25 years old were confined to the upper 24 inches (61 cm) of soil. Once a seedling reaches a height of about 3 feet (1 m), lateral roots begin rapid growth. [143]. Though Prunus spp. have been reported to be ectomycorrhizal, studies by Malloch and Malloch [85,86] in Ontario found no evidence of ectomycorrhizae in pin cherry roots. Endomycorrhizae were generally scarce in pin cherry roots, and most often absent altogether [85,86].

Pin cherry is short lived [63,109,127], maturing rapidly and dying off at 20 to 40 years [5,53,55,75,87]. Stands may begin to have a pulse of dead pin cherry wood deposition 15 years after disturbance. Pin cherry allocates relatively less carbon to structural stem issues and to fine roots than do other hardwoods, contributing to the common occurrence of stem snap at the root crown. Possible low production of defense compounds may encourage damage by insects and pathogens [68].

Distribution

provided by Fire Effects Information System Plants
Pin cherry occurs from Newfoundland and southern Labrador west across Canada to British Columbia and southern Northwest Territories. It is widespread in New England and the Lake States; south of Pennsylvania it occurs only in the Appalachian Mountains to northern Georgia and eastern Tennessee. Scattered stands are also found in the Rocky Mountains, south to Colorado and southeast to the Black Hills of South Dakota [19,53,72,78,79,143]. Prunus p. var. pensylvanica occurs throughout this range, while P. p. var. saximontana is restricted to British Columbia, Alberta, Montana, Wyoming, and Colorado [72]. The U.S. Geological Survey provides a distributional map of pin cherry.

Fire Ecology

More info for the terms: fire regime, forest, hardwood, seed, severity

Fire adaptations: Pin cherry has adapted to fire by establishing a soil seed bank that germinates rapidly following fire and other disturbance [32,116,133,144]. Pin cherry seed survives most forest fires, and seeds which may be dormant for many years are stimulated to germination by the altered conditions after fire [48,87,144]. Combined with the rapid initial growth of pin cherry seedlings [48,53,109], this characteristic enables pin cherry to dominate many burned-over areas, particularly in the northern hardwood forest [48]. For more information on pin cherry establishment and seedling growth see Botanical and Ecological Characteristics. Pin cherry sprouts after cutting [71], and though not documented, it may also sprout after fire. Further research is needed on postfire regeneration of pin cherry.

FIRE REGIMES: Pin cherry occurs in plant communities and ecosystems that historically experienced a range of FIRE REGIMES. In oak-hickory communities, for example, fires were typically frequent (<35-year mean), low-severity surface fires. Conversely, northern maple-beech-birch communities experienced long intervals between fire, and fire was usually stand-replacing [138]. White-red-jack pine communities experienced a mixed-severity regime with low to moderate severity at frequent intervals (20-40 years) and stand-replacing fires over longer intervals (100-300 years) [45]. FIRE REGIMES for plant communities and ecosystems in which pin cherry occurs are summarized below.

Fire Management Considerations

provided by Fire Effects Information System Plants
More info for the terms: basal area, density, forest, shrub, tree

Pin cherry seeds generally survive fire in the moist lower level of organic soil, which seldom burns completely. Numerous seedlings are often found the 1st growing season after fire. Seedling mortality is high, but some plants establish as part of the high shrub or low tree canopy in the developing forest [1,48]. Though pin cherry often dominates initial postfire vegetation [48], a study of a southern Appalachians spruce-Fraser fir forest found that by postfire year 25, pin cherry density was 182 stems/acre (455 stems/ha), comprising 12.2% of the total basal area [117,118]. Within 3 weeks of prescribed burning a harvested pine (Pinus spp.)-white spruce-hardwoods stand, pin cherry seedlings were abundant. By the next growing season, however, many of the pin cherry seedlings had died [124].

Habitat characteristics

Pin cherry has an elevational range from nearly sea level to over 9,000 feet (2,740 m) [19,24,31,42,53,75,105,117,129,143]. In the northeastern part of its range, pin cherry is found from 100 to 4,080 feet (30-1,240 m) [24,75]. In the southern Appalachians it generally occurs between 2,500 and 4,500 feet (762-1,370 m) [31,53,105,117,129,143]. In the western states, pin cherry is found between 5,000 and 9,300 feet (1,520-2,830 m) [42].

Throughout pin cherry's range, the number of days of snow cover ranges from 1 to 10 days in the South to 120+ days in the North [53]. Mean annual total snowfall ranges from 24 inches (610 mm) in the southern Appalachians to 100 inches (2,540 mm) in the northern part of the range. Average annual precipitation ranges from 16 inches (410 mm) in the West to 30 inches (760 mm) in Canada and 80 inches (2,030 mm) in the Great Smoky Mountains; average growing seasons vary from 100-210 days [23,53,118,143]. In the southern Appalachians, the average number of days with minimum temperatures below freezing is 90; in the northern and western part of pin cherry's range the number of days is more than 180 [143]. In Colorado, pin cherry is cold hardy to -50 oF (-45 oC) [23]. As demonstrated below, normal daily temperatures vary widely throughout the range of pin cherry (data are in oF/oC) [118,143]:

  Southeast Northeast and West January max. 50/10 30/-1 January min. 25/-4 -10/-23 July max. 80/27 85/29 July min. 50/10 40/4

Pin cherry grows on a wide range of soils and drainage classes [19,55,143]. Generally found on moderately coarse to coarse soils [61,109,127,137], pin cherry grows on sites varying from rocky ledges and sandy plains to moist loamy soils [19,23,55,143,143]. Pin cherry sites can be characterized as water-shedding (rocky ridges, cliffs, dry woods, clearings) or water-receiving (sandy and gravelly banks, shores of rivers and lakes) [109,127,137]. Pin cherry grows well on somewhat dry sites and shallow organic layers relatively low in nutrients [23,53,61,113,143]. Soils very low in moisture may result in a shrub form of pin cherry [66]. Though commonly found on mesic sites with nutrient-rich soil [25,53], pin cherry is generally absent from wet sites [109,143]. Optimum pH for pin cherry is 5.0 to 6.0 [53], though is also grows on more acidic soils [67].

Pin cherry is shade intolerant [18,25,27,53,75,91,109]. A study of shelterwood harvest in the northern hardwood forest of Vermont found that pin cherry increased in abundance with <60% canopy cover [60]. Pin cherry establishes in canopy gaps and proliferates with removal of overstory, increasing in density and cover [33,41,91]. It is frequent in burned areas, clearings, disturbed areas, roadsides, fencerows, and along forest margins [53,66,109,127,137]. A New Hampshire study found that pin cherry was relatively more abundant in recently created (24 years) gaps, large gaps (1,052-2,428 m2), and gap centers. Pin cherry abundance increased with gap size [91]. In a New England hardwoods forest, pin cherry growth exceeded that of other pioneer species near the center of clearcut openings, while other species sometimes grew faster near the side-shade zone at the edges of openings [126].

Importance to Livestock and Wildlife

provided by Fire Effects Information System Plants
More info for the terms: cover, forest

Pin cherry is important winter moose browse in the Great Lake states and boreal forest region [4,92,101,109]. Deer browse it moderately, especially in late winter and spring [3,53,109]. Pin cherry foliage and bark are important winter foods for snowshoe hares and cottontail rabbits  [39,53,109], and the bark is preferred fall and winter food for porcupines [132].

Pin cherries are important to wildlife; they are eaten in summer and fall by at least 25 nongame birds (e.g. American robins, bluebirds), several upland game birds (e.g. ruffed grouse), large and small mammals (e.g. black bears, raccoons), and game animals [17,53,109,114,119,136,143].When birds eat the cherries, they disgorge the stones after the pulp is ingested [17]. Upland game birds, especially sharp-tailed and ruffed grouse, eat pin cherry buds [53,143].

Palatability/nutritional value: Pin cherry is characterized as preferred moose browse in Newfoundland [43,69]. Pin cherry palatability for white-tailed deer is low in fall and winter months, but improves from April to September [65,69].

Average mid-summer nutrient concentrations of pin cherry leaves, stems, and roots, based on 4 years of sampling in New Hampshire hardwoods, follow [97]:

  Dry mass (%)   N P K Ca Mg leaves 3.57 0.221 1.685 0.61 0.287 stems 0.918 0.076 0.838 0.4 0.059 roots 0.728 0.065 0.634 0.342 0.063

Nutrient composition (in %) of pin cherry fruits from northern Ontario is presented below [135]:

Moisture content Dry matter Fat Protein Soluble carbohydrate based on glucose 70.22 29.78 1.99 1.53 11.45

Though deer browse pin cherry, its calcium:phosphorus ratio may be too high for deer nutrition [53]. Pin cherry has nutritional value similar to that of chokecherry [96]. The foliage of pin cherry contains hydrocyanic acid, and livestock browsing the leaves may be poisoned [93,109,143]; however, the toxicity of pin cherry leaves is lower than that of most other cherry species [143].

Cover value: Pin cherry generally provides fair to good cover for mule deer, white-tailed deer, and pronghorn, but provides poor cover for elk [42]. It offers good hiding cover for small mammals and fair to good nesting cover for nongame birds [42,53,109,143]

More info for the terms: fern, forest, hardwood, heath, shrubs, tree

In the northern part of its range, pin cherry occurs in virtually every forest
type. It is characteristically a short-lived, successional tree
in eastern hemlock (Tsuga
canadensis), northern hardwood, and spruce (Picea spp.)-fir (Abies
spp.) forests [53]. Pin cherry may also occur in pure stands, or more commonly, represent a majority of
stocking [55].

Pin cherry is found in the boreal forest region with white spruce (P. glauca),
black spruce (P. mariana), balsam fir (A. balsamea), paper
birch (Betula papyrifera), quaking aspen (Populus tremuloides),
chokecherry (Prunus virginiana), mountain maple (Acer spicatum),
speckled alder (Alnus rugosa), American green alder (A. crispa ssp.
crispa), oblongfruit serviceberry (Amelanchier bartramiana), roundleaf
serviceberry (A. sanguinea), California hazel (Corylus cornuta
var. californica), Bebb willow (Salix bebbiana), northern mountain-ash (Sorbus
decora), red raspberry (Rubus idaeus), skunk currant (Ribes glandulosum), wild sarsaparilla
(Aralia nudicaulis), fireweed (Epilobium angustifolium), whorled
wood aster (Oclemena acuminata),
bunchberry (Cornus canadensis), red-osier dogwood (C. sericea),
highbush cranberry (Viburnum edule), starflower (Trientalis borealis), and goldthread (Coptis
groenlandica) [20,33,49,139].


In the northern hardwoods region, frequent associates of pin cherry include quaking and bigtooth aspen
(Populus grandidentata); paper and
yellow birch (B. alleghaniensis); striped, red, and sugar maple (Acer
pensylvanicum, A. rubrum, and A. saccharum); American beech (Fagus
grandifolia), basswood (Tilia americana), eastern hemlock, northern red oak
(Quercus rubra), balsam
fir, and red spruce (Picea rubens) [24,36,55,143]. Prior to crown closure, raspberries (Rubus
spp.) and red elderberry (Sambucus racemosa ssp. pubens) are also abundant. Following stand closure,
these species are replaced by
shade-tolerant shrubs such as hobblebush (V. lantanoides) and Canada yew
(Taxus canadensis). Other common understory
plants include dwarf raspberry (R. arcticus ssp. acaulis), wild sarsaparilla, whorled wood
aster, bracken fern (Pteridium aquilinum), spinulose woodfern (Dryopteris
carthusiana), and shining clubmoss (Huperzia lucidula) [55,143]. In the Central and Lake States,
chokecherry (Prunus virginiana) and black
cherry (Prunus serotina) are particularly common associates [36,55,143].


In the southern and mid-Appalachian mountains, common pin cherry associates
are eastern hemlock; red spruce; Fraser fir (Abies fraseri); yellow and sweet birch (B. lenta);
American beech; pignut hickory (Carya glabra); sugar, red, mountain, and
striped maple; black cherry; American mountain-ash
(Sorbus americana); and northern red oak. Understory associates include
downy serviceberry (A. arborea), Allegheny serviceberry (A. laevis), Canadian serviceberry
(A. canadensis), flowering and alternate-leaf dogwood (Cornus florida and C. alternifolia),
red elderberry, southern bush honeysuckle (Diervilla
sessilifolia), mountain
holly (Ilex montana), mountain-laurel (Kalmia latifolia),
hobblebush, huckleberry (Vaccinium spp.), thornless blackberry (R. canadensis),
red raspberry, and Appalachian gooseberry (Ribes
rotundifolium) [24,30,31,34,55,81,105,143].


Pin cherry is also common in
heath balds adjacent to southern spruce-fir forests, occurring in thickets with
American mountain-ash, hawthorn (Crataegus spp.), mountain maple,
treefern (Dicksonia spp.), currants (Ribes spp.), raspberries (Rubus
spp.), sedges (Carex spp.), Catawba rosebay (Rhododendron catawbiense),

Management considerations

Due to its short life span and thin foliage, pin cherry is not usually considered
a serious competitor to commercially valuable hardwoods. However, high
densities of pin cherry may reduce the establishment and growth of commercial
hardwoods (e.g. black cherry, white ash, and sugar maple) [63]. Following clearcutting,
control plots in a northern hardwood forest study
demonstrated pin cherry dominance in stands aged 6 to 23 years. Basal area and
leaf area of pin cherry peaked at about year 17, followed by a steady decline in
pin cherry dominance. Fertilization treatments (combined N, P, K, Ca, Mg)
increased and prolonged pin cherry dominance, indicating that nutrient
limitation may accelerate the demise of pin cherry during the 2nd and 3rd
decades of stand development. In response to fertilization,
pin cherry had more leaf area pre unit stem basal area, and proportionally more
of this leaf area was in the upper canopy [14]. Demchik and Sharpe
[40], however, found little response of pin cherry to N-P-K
fertilizer following cutting. Frequency of pin cherry tends to increase after
stand harvest because seed stores well in the seed bank and is stimulated to
germinate when the canopy is opened [40]. Following cutting in a Massachusetts northern
hardwood forest, initial pin cherry density was approximately 40,000 stems/acre
(100,000 stems/ha).
Within 20 years, density decreased to 720 stems/acre (1,800 stems/ha), and
dropped to 5.6 stems/acre (14 stems/ha) after 40 years. Prior to cutting no pin cherry was documented
in the stand, illustrating the volume of seeds that may be buried in the seed
bank [5]. Due to the prolonged viability of pin cherry seeds
in the soil, harvest rotations of 120 years are recommended to allow sufficient
depletion of the pin cherry seed bank and stabilize population size. A study of
northern hardwood stands in New Hampshire found seed bank depletion to be
negligible in stands aged 40-60 years, and moderate (30% over 20 years) in
stands aged 95-115 years. Short harvest rotations (e.g. 60 years) may triple the
size of the pin cherry seed bank, resulting in greater proliferation
post-harvest [133]. Shading from slash cover may prevent pin
cherry germination and/or survival of new germinants [111].

Pin cherry responds well to clipping and/or browsing [3,29,40,53]; a study in the Lake States region found
annual growth increased by 88 to 121% following 4 years of  "heavy"
clipping [3]. A study in western Ontario found cutting of pin cherry stems
initially decreased density by 25% after 1 year. However, stem density in the
2nd and 3rd years exceeded precut levels by 5 and 8%, respectively. Stem thinning by
natural mortality in the untreated control plots was 41% to 69% over 4 years [84]. A New England study found that moose and
white-tailed deer preferred browsing taller pin cherry plants. Browsed plants
had higher relative
height growth following browsing (compensatory growth) than unbrowsed plants at
"low" and "intermediate" densities. Compensatory growth decreased with increased
density. Despite browser preference for taller plants, there was a clear
net growth advantage for pin cherry of initial large size, when the effects
of competition, browsing and compensatory growth were combined [121]. Though it
generally does well under moderate to heavy browsing [53], heavy browsing of pin cherry can nearly eliminate it from a site [126].
A Pennsylvania study found that white-tailed deer browsing significantly reduced (p<0.05) pin
cherry density [90]. Heavy barking of stems by snowshoe hares can cause pin
cherry mortality [39].


Pin cherry is easily controlled by 2,4-D, 2,4,5-T, and triclopyr
[29,98], and moderately controlled by hexazinone
[29,146] and glyphosate [29,83,98,103,130].
Yarborough and Bhowmik [146] found hexazinone significantly
reduced (p<0.05) cover and frequency of pin cherry. Raymond and others [107]
report a single application of glyphosate resulted in an 82% reduction
in pin cherry browse by posttreatment year 2. Mallik and others [84] found
that both single and multiple applications of glyphosate significantly reduced
(p=0.035) pin cherry stem density, achieving 90% mortality by the 3rd year
following treatment.



Pin cherry is susceptible to many diseases and parasitic insects [53,143]. Several leaf spot
pathogens infect pin cherry; the most
common is cherry leaf spot, Coccomyces hiemalis. Repeated attacks reduce
tree vigor. Additional pin cherry diseases are powdery mildew, rust, and leaf
curler. Pin cherry is also susceptible to extensive trunk rot (caused by
Fomes pomaceus) which delignifies the wood and leaves it soft, stringy, and
discolored with brown flecks. The most widespread and commonly observed disease
of pin cherry is black knot disease [143]. This disease (caused by Apiosporina morbosa)
may provide effective biological control of pin cherry, particularly if
introduced in the 1st 2 years of stand development. Establishment of the
pathogen occurs earlier and with more intensity in harvested than burned areas [140,141].
A Nova Scotia study found that introducing
black knot disease 3 years after disturbance ended site dominance by pin cherry
during the subsequent 5 years [140]. Following cutting, pin cherry stump
treatments with fungal isolates of Chondrostereum purpureum may be
effective in controlling sprouting [70,142]. Insect attacks on
pin cherry primarily consist of leaf feeders [143].

Other uses and values

More info for the terms: fruit, fuel

Pin cherry currently has little commercial value [63], though recent interest in commercial production of pin cherry fruit has emerged [122]. The fruit is edible and can be used in jams and preserves [109,137].

Wood Products: Pin cherry wood is light, moderately soft, porous, and low in strength [66,143] giving it little commercial value. In general, pin cherry is not used for lumber and is considered a noncommercial species. It occurs in abundance, however, over a wide range of sites and produces large quantities of biomass in a relatively short time. The species has been described as well adapted to intensive management and chip harvesting on short rotations for fiber and fuel [143]

Plant Response to Fire

provided by Fire Effects Information System Plants
More info for the term: seed

Pin cherry establishes and reproduces abundantly and at an early age after fire [11,125,145]. Burning provides a good seed bed for pin cherry germination [2]; as a result, pin cherry is often more frequent on burned than unburned sites [29,95]. Dormant seeds germinate in response to disturbance by fire. This response, combined with the rapid initial growth of seedlings, enables pin cherry to dominate recently burned over sites [48].

Regeneration Processes

provided by Fire Effects Information System Plants
More info for the terms: basal area, bisexual, density, duff, forest, formation, fruit, hardwood, presence, seed

Pin cherry regenerates by both seed and sprouts. However, in a 25-year-old Maine hardwood forest 1 year after clearcutting, pin cherry was represented primarily by seedlings, not sprouts [144].

Breeding system: The flowers of nearly all Prunus species are bisexual [57].

Pollination: Prunus species are insect-pollinated [57].

Seed production: Pin cherry produces abundant seed at early ages [63]. Sexual maturity may be reached as early as 2 years [87,133,143], though large quantities of fruit are generally not produced for several years later [143]. Fruit is produced annually with large crops occurring every 2 to 3 years [87]. By the time pin cherry dies off (20 to 40 years), sufficient numbers of seeds have been produced and disseminated in a dormant condition for the reestablishment of pin cherry following disturbance [87,133]. Despite its short life span, fruit production of pin cherry is high. In New Hampshire, annual fruit production of 15-year-old, open-grown trees in pure stands was estimated at 1,118,000 fruits/acre (2,762,500/ha). For 25-year-old pin cherry stands in the same area, annual seed production was 940,700 seeds/acre (2,324,500/ha) [143]. Seed production peaks between 10 and 25 years, declining thereafter [22,133].

Seed dispersal: Pin cherry seeds are dispersed by birds, small mammals [53,55,87,143], and gravity [53,143].

Seed banking: As part of its reproductive strategy, pin cherry maintains a bank of seeds in the soil that remain viable for many years [32,133]. Seeds accumulate over prolonged periods (e.g. 50 years) [12,87,89], and most pin cherry seeds available for establishment following disturbance in mature stands (~100 years) are the result of seed banking rather than recently dispersed seed [55,89]. In a clearcut Maine hardwood forest, pin cherry seedlings were numerous although occurrence in surrounding stands and presumably in the preharvest stand was low [144]. Estimates of pin cherry seed contained in the duff of middle-aged northeastern deciduous forests range from 100,000 to >1.8 million per acre (250,000-4.5 million/ha) [11]. In 2 areas in New Hampshire, the average number of viable pin cherry seeds in the forest floor ranged from 139,676/acre (345,000/ha) to 200,000/acre (494,000/ha). In other New Hampshire stands, depending on stand age, the number of viable seeds in the forest floor ranged from 4,050 to 450,000/acre (10,000-1,110,500/ha) [143]. The distribution of pin cherry seeds in the forest floor is influenced by prior colonization of the site by pin cherry; dissemination of fruits by birds; and small mammal caches that tend to shift the distribution of seeds toward more or less discrete aggregations [32,87]. Longevity of buried pin cherry seeds has been estimated at 50 to 100 years [55,87]; pin cherry establishment after the removal of older stands relies primarily on seed dispersal into disturbed areas [55].  Seeds lose viability over time, so the pin cherry seed bank is eventually depleted in the absence of large-scale disturbance. The seed bank may persist at least 30 years after production ceases with little depletion, but is depleted gradually thereafter [22,133]. Seed bank losses are the result of seed rot and consumption by small mammals [32].

Germination: Pin cherry germination requires 1) the aging of the endocarp, either to break down an inhibitor or to increase permeability; and 2) an altered microclimate conducive to germination [87]. Dormancy of pin cherry seeds is caused by an initial physiological inhibition for several years followed by a secondary dormancy that remains until germination is stimulated by disturbance [133]. Because pin cherry seeds require open conditions for germination, there is often a prolonged delay between seed dispersal and germination [32]. Pin cherry seed banks may germinate in response to changes in soil temperature, light, or other triggering factors associated with the formation of a large gap due to disturbance [12,32,87,110]. However, the specific aspect of the changed environment that triggers germination is not known [32]. A study of stand development in Nova Scotia found higher incidence of pin cherry regeneration on soil disturbed by logging machinery than on undisturbed soil [139]. Laboratory experiments indicate that germination in open areas may be related to more extreme temperature fluctuations [76,143]. Germination may also be promoted by increased soluble nitrogen concentrations in the soil, based on increases in pin cherry germination following nitrogen (especially nitrate) fertilization [11].

The presence of occasional pin cherry seedlings beneath the canopy of undisturbed forest suggests that at least some germination occurs on a regular or annual basis [32,87,143]; however, seedlings have been reported to survive only in large openings where light and moisture were more available [143].

Seedling establishment/growth: Pin cherry establishment is directly related to open stand conditions. In a study of spruce-balsam fir forest canopy disturbance (spruce budworm outbreak), pin cherry established in greater abundance with 100% canopy removal than with partial canopy removal [99]. When established in high density, pin cherry grows quickly with early attainment of canopy closure [87]. When pin cherry occurs in high density (more than one 5-foot stem/43 ft2 (1.5-m/4 m)), it may live longer than when occurring at lower density (less than one 5-foot stem/43 ft2), because high pin cherry density early in stand development delays the time when shade-tolerant species reach a stable proportion of the total basal area. Pin cherry develops an early height advantage over other species, and as pin cherry density increases, growth and survival of other hardwood (black cherry, red maple, sugar maple) seedlings decreases. A study of an Allegheny hardwood stand found that survival of black cherry, red maple, and sugar maple at age 15 decreased as the density of pin cherry >5 feet (1.5 m) tall at age 3 increased. The height of black cherry and white ash (Fraxinus americana) also decreased [110]. In dense stands, the pin cherry canopy closes in about 3 years, shading out many of the other early intolerant species. After 25-30 years, sugar maple, beech and balsam fir are the seral species. At intermediate densities, pin cherry may codominate with yellow birch, paper birch, and quaking aspen. At low densities, dominance is shared by many species including blackberries, striped maple, paper and yellow birch, quaking aspen, and stump sprouts of cut trees [143].

Pin cherry exhibits a strong self-thinning tendency. On a jack pine (Pinus banksiana) plantation in Ontario, pin cherry density (sprouting) was 1,440 stems/acre (3,600 stems/ha) 4 years after harvest and fell to 488 stems/acre (1,220 stems/ha) 6 years after harvest [82]. In a study of Allegheny hardwoods, pin cherry seedlings ranged from 1,400 to 78,000 stems/acre (3,500-195,000 stems/ha) 1 year after overstory removal. First-year seedlings were less than 5 feet (1.5 m) tall. By year 3, stands averaged 6,800 stems/acre (17,000 stems/ha), and trees were more than 5 feet tall. After year 5, the number of pin cherry stems declined rapidly and only 1,600 stems/acre (4,000 stems/ha) remained at year 15. The 15-year-old stems exceeded 39 feet (12 m) in height [110].

Pin cherry seedlings grow rapidly, especially when young [53,109]. It is not uncommon for pin cherry growing on good sites in the central Appalachians to reach 8 to 10 inches (20-25 cm) in diameter in 25 years. Rapid growth is directly related to the amount of light received [143]. In preliminary results, Roberts [112] found height growth of pin cherry seedlings was significantly greater (p<0.05) under partial-canopy (4.4 feet (1.3 m) tall) and open-canopy (9.8 feet (3 m) tall) conditions than under closed-canopy conditions (1.2 feet (0.4 m) tall).

Asexual regeneration: Once established, pin cherry seedlings may reproduce by sprouting and may form thickets [53]. Pin cherry has a high potential for stem sprouting and root suckering after cutting [71,71,143]. In a Quebec study most of the suckers forming a clone emerged 1 to 2 years after the parent stem was cut, with the number of suckers per clone ranging from 11 to 32. The largest clone studied covered 153 square feet (14.25 m2) [71].

Successional Status

More info for the terms: basal area, competition, density, forest, hardwood, phase, presence, seed, succession

Pin cherry is an early to mid-seral species, important in both primary and secondary succession after fire or harvest [12,20,32,35,105,145]. Pin cherry is common in rock- and soil-slide succession, but is usually far more numerous after windthrow, logging, or light fires because its presence is highly dependent on seed buried in the forest floor [29,143]. Pin cherry does, however, colonize through "seeding in" [29,87]. It is generally restricted to sites that supported forest vegetation prior to disturbance; it is not common in abandoned pastures or old fields. Pin cherry is further restricted to colonization of open areas larger than about 0.25 acre (0.1 ha) [87].

Pin cherry is a particularly common successional species in northern hardwood and spruce-fir forest ecosystems, dying out relatively quickly as seral stands develop [24,49,87,139]. For example, pin cherry that established following a landslide in the northeastern spruce-fir zone was no longer present in the stand after 40 years [50]. In northern hardwood forests, pin cherry grows quickly after stands are cut and is often the tallest species from the 2nd to the 6th year of stand regrowth [27]. Pin cherry can be an effective competitor on disturbed sites [63,109] because it employs a vertical competition strategy, competing with other species for light by overtopping them due to rapid height growth [82].  Pin cherry often dominates regenerating northern hardwood or spruce stands (up to 70% of stems) for 15-20 years after disturbance [48,53,80,133,145], though it may die out sooner [48]. Pin cherry may also codominate with aspen, black cherry, red maple, and white or gray birch [53].

The pin cherry forest type develops rapidly, forming a closed canopy in 3 to 7 years and reaching maturity in 20 to 30 years [55]. Dominance shifts to mature forest species after approximately 30 years, and pin cherry rarely persists in stands after 40 years due to a combination of nutrient limitation, shade intolerance, and the relatively short life span of pin cherry [5,11,55,133]. A study in New England hardwoods found pin cherry was initially prominent following clearcutting, especially near the center of openings, but had died or become moribund after 20 years [126]. The initial density of pin cherry stands, determined by available buried seed, is an important determinant of succession. Where pin cherry is very dense, canopy closure limits the establishment and growth of other early successional species. Succession occurs in 2 distinct phases: the 1st is characterized by an almost pure pin cherry overstory and sparse understory; the 2nd phase involves the relatively abrupt dominance by shade tolerant species like sugar maple, beech, and balsam fir. At intermediate densities, pin cherry may codominate with other fast-growing species (e.g. yellow birch, paper birch, quaking aspen, bigtooth aspen), with shade-tolerant species gaining dominance gradually because shade-intolerant species die and are replaced at different times [55,63,87]. Successional patterns in low-density stands of pin cherry are quite variable, primarily because the rate of canopy closure is slower [87]. Repeated disturbance may result in persistent dominance of pin cherry or codominance of pin cherry and aspens [80].

At lower elevations in New England, pin cherry succeeds to aspens, white pine, or white pine-northern red oak-red maple. In the southern Appalachians, succession is to red spruce, red spruce-Fraser fir, or northern hardwoods [55]. Twenty-five years after a fire in the Southern Appalachian spruce-fir forest, pin cherry density was 182 trees per acre (455 trees/ha), comprising 12.2% of total basal area, while Fraser fir had reached 531 stems per acre (1,327 stems/ha) and comprised 63.8% of total basal area [117,118]. This seral community was still several decades from a mature, closed-canopy spruce-fir forest. Pin cherry may persist longer on sites where severe fire, steep slopes, and shallow soil combine to slow development of mature stands [117].

Pin cherry sequesters nutrients that might otherwise be lost from the ecosystem during early stages of succession [88,109,133]. Rapid establishment and growth of pin cherry minimizes nutrient loss by 1) channeling water from runoff to evapotranspiration, reducing erosion and nutrient loss; 2) reduction in rates of decomposition through moderation of the microclimate during the growing season so that the supply of soluble ions available for loss in drainage water is reduced; and 3) incorporation into the rapidly developing biomass of nutrients that do become available and that may otherwise might be lost from the system [88].

Value for rehabilitation of disturbed sites

More info for the terms: scarification, seed, stratification

Propagation: Soaking the seeds is helpful for pin cherry propagation, but scarification is unnecessary [53]. Seed germination rate can be improved by drastic temperature fluctuation treatments. Effective treatment involves a 24-hour soak followed by 30 days of stratification with 5 days at 41 oF (5 oC) alternating with 5 days at 86 oF (30 oC). The next step is 60 to 90 days of stratification at 41 oF, followed by a 10-day germination period with 12 hours at 41 oF alternating with 12 hours at 86 oF. This procedure can be expected to achieve at least 75% germination [76]. Belcher [19] recommends prechilling 60 to 90 days at 37 to 41 oF (3-5 oC) and encouraging germination with temperatures from 68 to 86 oF (20-30 oC). Air-dried seeds can be stored at 37 to 41 oF for 3-5 years [19]. Pin cherry seeds have retained viability for up to 10 years when stored in sealed containers at 34 to 38 oF (1-3 oC) [53].

Pin cherry suckers readily and is assumed by some authors to grow well from root cuttings [143]. However, propagation of pin cherry from cuttings has proved difficult with little success reported [23]. Pin cherry is used as grafting stock for sour cherry (Prunus cerasus) [53,143].

Restoration: Pin cherry grows naturally on unreclaimed coal mine spoils [53,67]

Damaging Agents

provided by Silvics of North America
Many diseases attack pin cherry during its short life. The most common leaf disease is cherry leaf spot, Coccomyces hiemalis, which is recognized by purplish to brown shot holes in the leaves that eventually cause yellowing of leaves and premature leaf fall. Repeated attacks reduce tree vigor. Other leaf spots on pin cherry are caused by Cercospora circumscissa, Coryneum carpophyllum, and three species of Phyllosticta. Additional pin cherry diseases are powdery mildew, Podosphaera oxyacanthae var. tridactyla; rust, Tranzschelia pruni-spinosae; and leaf curler, Taphrina cerasi.

The most widespread and commonly observed disease of pin cherry is black knot, Apiosporina morbosa (31). Extensive trunk rot in the East is caused by Fomes pomaceus. This decay delignifies the wood, which then becomes soft, stringy, and discolored with brown flecks and streaks (18).

Most of the important insects that attack pin cherry are leaf feeders, but because of the low economic value of pin cherry, they are considered unimportant. A major leaf feeder is the uglynest caterpillar, Archips cerasivoranus (Fitch) and occasionally the eastern tent caterpillar, Malacosoma americanum (17,30). Other leaf feeders are the cherry leaf beetle, Pyrrhalta cavicollis, a relative of the elm leaf beetle; Bruce spanworm, Operophtera bruceata; fall canker worm, Alsophila pometaria; and a web-spinning sawfly, Neurotoma fasciata (4). Many other insects attack Prunus, but there are only a few references to their attacks on pin cherry.

Flowering and Fruiting

provided by Silvics of North America
Pin cherry flowers from late March to early July. Flower buds are formed in August or September of the preceding year (17). In Warren County, PA, flowers appear from May 1 to May 15. The perfect flowers are white and 12 to 16 min (0.47 to 0.63 in) broad with long pedicels; they are borne in corymbs or umbels and expand with the leaves. The globose fruits ripen from July to September, depending on locality. They are light red, 5 to 7 min (0.20 to 0.28 in) in diameter, and have thin, acid flesh and subglobose stones 4 to 5 mm (0.16 to 0.20 in) long (9,10,16). Fruiting occurs as early as age 2 in natural stands in Pennsylvania (16). Sexual maturity of natural dominant trees in New Hampshire may be attained during the fourth growing season though large quantities of fruits are not produced until several years later (23).

Growth and Yield

provided by Silvics of North America
Information on the growth and yield of pin cherry is scarce. In thickets, it forms a closed canopy in 3 to 7 years and reaches maturity in 20 to 40 years (14). On dry, compact glacial till soils in New Hampshire, where pin cherry may comprise 50 percent of the species composition in sapling stands, mean annual biomass production was 3290 kg/ha (2,931 lb/acre), mean annual basal area growth was 1.30 m²/ha (5.66 ft²/acre), mean annual d.b.h growth was 2 mm (0.08 in), and mean annual height growth was 0.23 m (0.75 ft) (21).

When young stands of northern hardwoods are cut, nearly pure stands of pin cherry often become established. When the pin cherry dies, the succession is to sugar maple and beech. When older stands are cut and the initial density of pin cherry is lower, the succession is towards quaking aspen and bigtooth aspen, yellow birch and paper birch. On lower elevations in New England and south through the Appalachians, the succession is to the White Pine-Northern Red Oak-Red Maple, White Pine, Red Spruce, or Red Spruce-Fraser Fir types, or to the northern hardwood types (14).

Pin cherry growth is rapid, and it is not uncommon for trees growing on better sites in the central Appalachians to reach 20 to 25 cm (8 to 10 in) in diameter in 25 years (25). Pin cherry rarely persists in eastern upland hardwood forests in the United States for more than 35 years (2).

Annual biomass production, including belowground material, in 6-year-old stands of pin cherry was about 1660 g/m² (0.34 lb/ft²), which is higher than production in other temperate climate forests (22).

Reaction to Competition

provided by Silvics of North America
Pin cherry is classed as very intolerant of shade. Early height growth is rapid, and where there is a high concentration of buried seed to produce seedlings after cutting or burning, pin cherry usually is dominant over all other vegetation.

In dense stands, the canopy closes in about 3 years, shading out many of the early intolerant species. After 25 to 30 years, sugar maple, beech, and in the northernmost regions, balsam fir are the seral species. At intermediate densities, pin cherry may be codominant with yellow birch, paper birch, and quaking aspen. At low densities, dominance is shared by many species including blackberries, striped maple paper and yellow birch, quaking aspen, and stump sprouts of cut trees (23).

Rooting Habit

provided by Silvics of North America
Once a seedling attains a height of about 1 m (3 ft), lateral roots begin rapid growth (17). In New England, root systems in 4- to 14-yearold stands were found to be shallow, generally not over 36 cm (14 in) deep, and to have many lateral branches (23). In West Virginia, root systems of wind-thrown trees 25 years old were found to be confined to the upper 61 cm. (24 in) of soil (25). New shoots can arise from pieces of root left in the soil following site disturbance. Root cuttings, about 10 cm (4 in) in length, rooted 33 percent when incubated in soil under favorable greenhouse conditions (17).

Seed Production and Dissemination

provided by Silvics of North America
Fruits are dispersed by gravity and to a much lesser degree by birds and small mammals after the fruits ripen in July (12). The weight of cleaned seeds per 45 kg (100 lb) of fruit ranges from 7 to 12 kg (16 to 27 lb). The number of cleaned seeds per kilogram ranges from 17,600 (8,000/lb) to 48,100 (21,800/lb) and averages about 31,300/kg (14,200/lb) (16).

In a 4-year study on the Monongahela National Forest in West Virginia, trees with an average d.b.h. of 12 cm (4.7 in) yielded 0.64 liter (0.68 qt) of fruit per tree (26). Half the trees bore fruit, and fruit yields varied substantially from year to year. Fruits were produced at 3- to 4-year intervals. In New Hampshire, dominant trees produced some fruit at 4 years, but quantity production occurred later.

Despite its short life span of about 30 years, fruit production in pin cherry is high. For 15-year-old, open-grown trees in pure stands, annual fruit production was estimated at 2,762,500 fruits per hectare (1,118,000/acre). For 25-year-old pin cherry stands in the same area of New Hampshire, annual seed production was 2,324,500/ha (940,700/acre) (23).

Many seeds remain buried in the soil in areas where pin cherry once grew. Some seeds are disseminated by birds that excrete or regurgitate the seeds at a distance from their source, and some are moved by mammals (1,23). In two areas in New Hampshire, the average number of viable pin cherry seeds in the forest floor ranged from 345,000/ha (139,676/acre) to 494,000/ha (200,000/acre) (23). In other New Hampshire stands, depending on stand age, the number of viable seeds in the forest floor ranged from 10,000 to 1,110,500/ha (4,050 to 450,000/acre) (15). It has been estimated that some seeds buried in the soil retain their viability for 50 to 150 years (15,22).

Seedling Development

provided by Silvics of North America
Pin cherry germination is epigeal and most pin cherry reproduction arises from seed stored in the forest floor. In natural stands in northwestern Pennsylvania, Marquis (24) reported 36,800/ha (14,900/acre), 14,100/ha (5,700/acre), and 46,700/ha (18,900/acre) pin cherry seedlings germinating after removal of one-half, two-thirds, and all of the overstory, respectively.

In New England, more pin cherry seedlings germinated from soil blocks taken from 38- and 95-yearold stands than from 5- or 200-year-old stands (15). More than 70 percent germinated during the first summer in the 38- and 95-year-old stand samples. The number of germinating seeds was 2, 111, 52, and 1 per m² (from fewer than 1 to 10/ft²) for the 5-, 38-, 95-, and 200-year-old stands, respectively.

In the central Appalachians in West Virginia, dense thickets of pin cherry frequently develop after clearcutting 40- to 70-year-old hardwood stands. On two areas 5 years after clearcutting, there were between 2,470 and 7,410 pin cherry seedlings/ha (1,000 and 3,000/acre) 0.3 m (1.0 ft) high and up to 2.5 cm (1.0 in) in d.b.h. and between 680 and 990 stems/ha (275 to 400/acre) 2.5 to 12.7 cm (1.0 to 5.0 in) d.b.h. (25).

A small amount of pin cherry seed probably germinates annually in northern hardwood stands. However, seedlings have been reported to survive only in large openings where light and moisture were more available. The largest number of pin cherry seedlings appeared in response to major disturbances such as heavy cutting or burning (23). In one study, mechanical removal of the endocarp and a cool temperature, 15° C (59° F), promoted better pin cherry germination. The germination rate of pin cherry was greatly improved by soaking seed for 24 hours in a chemical solution (0.5 M hydroxylammonium chloride) followed by a series of drastic temperature fluctuation treatments (20). With this treatment the seed germination rate was more than 75 percent. Often pin cherry seed germination is less than 10 percent when seed viability is 100 percent. It appears that the factor triggering increased germination of buried pin cherry seed following forest disturbance is the more extreme temperature fluctuation created by removing the overstory (20). Although the factors accounting for the natural germination of pin cherry could not be determined exactly, apparently (a) time is needed to age the endocarp so it becomes more permeable to water and oxygen, and (b) changes in soil and water chemistry in response to the altered microclimate of a disturbed site or to other conditions is necessary (22).

In northeastern Pennsylvania, pin cherry germination generally increased with light under no moisture stress, but under normal moisture stress, germination was best under partial shade. Under heavy shade, pin cherry seedling mortality is high, but with increasing light, survival is increased. Growth of seedlings is rapid and directly related to the amount of light received (24). Repeated applications of N to existing sawtimber stands could reduce the pin cherry component in future stands. In situations where pin cherry outgrows other more desirable species after regeneration cuttings, N fertilization might benefit maturing stands by increasing growth rates of residual trees and reducing the numbers of pin cherry seeds that would germinate and later compete with preferred reproduction (2).

Ripened fruits of pin cherry should be collected from trees or from the ground in late summer. For storage the pulp should be removed and the seeds stored in sealed containers at 1° to 3° C (34° to 38° F). Seed viability has been retained for up to 10 years under these conditions (12).

For nursery sowing, pin cherry seed should be stratified in moist sand for 60 days at alternating temperatures of 20° to 30° C (68° to 86° F) and for 90 days between 3° to 5° C (37° to 41° F) (16).

Special Uses

provided by Silvics of North America
Twenty-five species of nongame birds, several upland game birds, fur and game mammals, and small mammals eat pin cherry fruit. Buds are eaten by upland game birds, especially sharp-tailed and

ruffed grouse. Foliage and twigs are browsed by deer. However, the foliage has a high calcium to phosphorous ratio which is undesirable for good deer nutrition. Except in dense thickets, pin cherry provides only fair nesting cover and materials for birds. Beavers cut pin cherry and may completely remove small stands (12). Leaves are poison (hydrocyanic acid) to livestock under certain conditions. However, the toxicity of pin cherry leaves is lower than that of most other cherry species (17).

Because of its early place in succession and its rapid growth, pin cherry is important for minimizing losses of nutrients from an ecosystem. The rapid development of early successional species, such as pin cherry, channels water from runoff to evapotranspiration, thereby reducing erosion and nutrient loss; modifies the microclimate which reduces the rate of decomposition of litter and production of soluble ions; and incorporates into the developing biomass nutrients that do become available (22).

In general, pin cherry is not used for lumber and is considered a noncommercial species. It occurs in abundance, however, over a wide range of sites and produces large quantities of biomass in a relatively short time. The species has been described as well adapted to intensive management and chip harvesting on short rotations for fiber and fuel (13). At least one paper company accepts pin cherry along with other hardwood species in West Virginia (8). Undoubtedly, it is also mixed with hardwoods in other areas.

In the nursery trade, pin cherry has been used as a grafting and budding stock for sour cherry (12,29).

Brief Summary

provided by Silvics of North America
Rosaceae -- Rose family

G. W. Wendel

Pin cherry (Prunus pensylvanica) is a small common tree inhabiting a great variety of lands in the northern part of the United States and Canada. It is sometimes called fire cherry for its value as a reforesting agent after forest fires. It forms pure stands that provide shade for seedlings of slower growing species, then dies off, making way for the new trees. Another common name, bird cherry, reflects the prevalent use of the fruit by birds as food. It is also called northern pin cherry, wild red cherry, and pigeon cherry. The soft porous wood is of little commercial value.

Distribution

provided by Silvics of North America
Pin cherry grows from Newfoundland and Labrador west to southern Mackenzie District and British Columbia in Canada. Scattered stands are found south in the Rocky Mountains to Montana and Colorado; southeastward from the Black Hills of South Dakota to Iowa, Illinois, Pennsylvania, and New Jersey, northeast to New England. In the Southeast its range follows the Appalachian Mountains south to northern Georgia and eastern Tennessee.

Prunus pensylvanica

provided by wikipedia EN

Prunus pensylvanica, also known as bird cherry,[3] fire cherry,[3] pin cherry,[3] and red cherry,[3] is a North American cherry species in the genus Prunus.

Description

Prunus pensylvanica grows as a shrub or small tree, usually with a straight trunk and a narrow, round-topped crown. It grows 5–15 metres (16–49 feet) tall and 10–51 centimetres (4–20 inches) in diameter. Trees up to 30 m (98 ft) tall have been found growing in the southern Appalachians, with the largest found on the western slopes of the Great Smoky Mountains. Its foliage is thin,[5] with leaves 4–11 cm (1+124+14 in) long and 1–4.5 cm (381+34 in) wide. Flowers occur in small groupings of five to seven with individual flowers 1 cm (12 in) across. The fruit are drupes, ranging from 4–8 millimetres (1838 in), each with a single seed 4–6 mm (31614 in) in diameter contained within a hard "stone".[6][7]

Distribution

The species is widespread across much of Canada from Newfoundland and southern Labrador to British Columbia and the southern Northwest Territories. Additionally it is very common in New England and the Great Lakes region. It can also be found in the Appalachian Mountains as far south as northern Georgia and eastern Tennessee. Scattered growth of the pin cherry also occurs in the Rocky Mountains, south to Colorado as well as in the Black Hills of South Dakota.[8]

Ecology

The pin cherry can regenerate by seed and sprout. Its flowers are bisexual and pollinated by insects. Seeds are dispersed by birds, small mammals, and gravity. As part of its reproductive strategy, pin cherries seeds can remain viable in the soil for many years. Seeds accumulate over prolonged periods, and soil seed banks may be viable for 50–100 years. Asexual reproduction is achieved by sprouting, and often thickets of pin cherry plants form.[6]

The pin cherry is rather short lived, having a lifespan of only 20 to 40 years following a rapid maturation. Its root system is shallow, with roots tending to grow laterally. It is an important food source for many animals. Winter moose browse it in the Great Lake states and boreal forest region.[6]

Though they are documented to sprout following cutting, individual pin cherry thickets are often killed if exposed to fire. Nonetheless, they have adapted as a species by the establishment of their seed banks which are protected from the most severe heat by their soil cover and fed by the nutrients in the resultant ash residue. Following a fire or other disturbance, seeds which may be dormant for years will germinate rapidly, stimulated by the altered conditions after fire. Combined with the rapid initial growth of seedlings, these characteristics enable groupings of Pin cherry thickets to dominate many burned-over areas, particularly in the northern hardwood forest.

The pin cherry serves as food for various Lepidoptera.

Uses

Culinary

Pin cherry currently has little commercial value, though recent interest in commercial production of pin cherry fruit has emerged. The fruit is edible and can be used in jams, jellies, and preserves.[9]

Lumber

Pin cherry wood is light, moderately soft, porous, and low in strength giving it little commercial value. In general, it is not used for lumber and is considered a noncommercial species. It occurs in abundance, however, over a wide range of sites and produces large quantities of biomass in a relatively short time. The species has been described as well adapted to intensive management and chip harvesting on short rotations for fiber and fuel.
