Brief Summary

provided by EOL authors

Redbay (Persea borbonia) is a perennial evergreen tree in the laurel family (Lauraceae).It is native to the Southeastern United States, and grows along the Gulf coast plain patchily in Texas and Louisiana, from Mississippi across panhandle and peninsular Florida and north to North Carolina and the southeast coast of Virginia.It also grows in the Bahamas and is cultivated in Hawaii. Redbay usually grows on the borders of swamp land.It is also known as tisswood, scrubbay, shorebay, and swampbay.

Persea borbonia grows as either a small tree or a large shrub. Its lance-shaped leaves are about 3 to 6 inches long, bright to dark green in color, and arranged alternately on the stem.When crushed, the leaves emit a spicy smell.In April-May, small white flowers form on axils branching from new growth.Bees and wind pollinate the flowers.Blue or black drupe fruits ripen in August-September.Songbirds, white-tailed deer, bobwhite quail, wild turkey, and black bear eat the fruit and disseminate the seeds. Deer and bear also browse redbay foliage, consuming up to as much as 40% of its annual growth without jeopardizing the tree.In some habitats redbay provides essential habitat for gray squirrels.

Redbay is not widely used in the present day for medicinal uses, however the Seminole Indians used to use it as an emetic to induce vomiting.The dried leaves can be used as an alternative to tropical bay spice for cooking.The wood is hard and strong, and used locally to build boats, cabinets and for lining the interior of structures.Persea borbonia is cultivated as an ornamental tree for gardens and parks.

In 2002 an ambrosia beetle (Xyleborus glabratus) was discovered as a recent introduction to the Southeastern United States from Asia.Now called the redbay ambrosia beetle, it arrived with a fungal symbiont (Raffaelea lauricola) which the adult and larvae cultivate as their food source.The ambrosia beetle bores into the wood of healthy trees, inoculating the xylem with the fungi.The fungi plug the tree’s xylem and prevent transport of water, causing wilting symptoms.At this point, the diseased tree is susceptible to other ambrosia beetles and their associated fungi.These pathogens cause rapid discoloration of foliage and wood and the tree dies within months.Although still a new pathogen complex, the beetle-fungi complex appears to spread rapidly, and is thought to be a very high risk pest to redbay and other laurel species with a potentially huge impact on these flora.As yet there is no known means of preventing the spread of the redbay ambrosia beetle.

Description

provided by Fire Effects Information System Plants
More info for the terms: perfect, tree

Redbay's growth habit varies over its range [5]. It usually grows as a
medium-sized tree, commonly shrubby, up to 45 feet (15 m) tall [13,20].
Occasionally, old trees may reach a d.b.h. of 3 feet (1 m), with a large
crown [20]. In southern Florida hammocks, redbay grows branched and
crooked, seldom achieving tree form [15].

Redbay leaves are alternate, simple, evergreen, and aromatic [13].
Stomatal characteristics suggest adaptation for water conservation [14].
Redbay flowers are perfect, small, cymes [5,12]. Annually produced
fruits are drupes which turn black or blue as they ripen [5].

Fire Ecology

provided by Fire Effects Information System Plants
More info for the terms: fire intensity, fire regime, moderate-severity fire

The postfire survival of redbay apparently depends on fire intensity.
After moderate-severity fire which top-kills only small-diameter redbay,
redbay stands persist through sprouting and the survival of large
individuals [7]. Severe fire may eliminate all age classes.

Fire Management Considerations

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

Redbay should be protected from fire [27] or subjected only to
low-severity prescribed fires [13] where wildlife habitat maintenance is
a goal. Atlantic white-cedar production may benefit from frequent fires
which reduce redbay competition [9,34]. Consult Hough [21] to predict
potential heat release when burning in redbay stands.

Habitat characteristics

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

Redbay soils are frequently Histosols consisting of a thick layer of
peat [15,36], a sandy-humis, or an organic muck [36]. When layered over
the Everglades' marl these soils may be basic [15], although throughout
most of redbay's range these soils are acidic [36]. The soils are
infertile [7] and provide poor mechanical support [5].

The climate throughout redbay's range is warm-temperate to subtropical.
The frost-free period is usually greater than 250 days per year and
normal temperatures range from 100 to 10 degrees F (38-minus 12 deg C).
Mean annual rainfall is between 52 and 64 inches (1,020 and 1,630 mm)
and is well distributed seasonally [5].

Immediate Effect of Fire

provided by Fire Effects Information System Plants
More info for the term: top-kill

Aromatic leaves and a dense, shrubby growth form [7] favor intense fires
in redbay stands. Most fires probably kill or at least top-kill redbay,
since it appears to survive only moderate-severity fires. Those
individuals that survive fire may experience delayed mortality because
of fire-related scarring and stem deterioration [5].

More info for the term: fruit

Wild turkeys and many songbirds eat redbay fruit [5]. The northern
bobwhite eats red bay seeds, especially during the winter [5,27].
White-tailed deer and black bears eat the foliage and fruit of redbay.
Redbay can sustain browsing of up to 40 percent of its current annual
growth [5]. In otherwise pure stands of even-age pine in southern
Alabama, redbay-dominated "stringers" provide essential habitat for
gray squirrels [18].

Key Plant Community Associations

provided by Fire Effects Information System Plants
More info for the terms: hardwood, mesic, swamp, tree, xeric

Redbay is common in pocosins [10,30], forested wetlands [1], mixed
hardwood swamps [38,40], and Mississippi pitcher-plant (Sarrecenia spp.)
bogs [16]. In the drier Big Thicket area of eastern Texas, it sometimes
grows on upland longleaf pine (Pinus palustris) savannas [6,33] and
poorly drained sites where mesic vegetation form localized patches in a
more xeric landscape [41]. Redbay is a principal associate in the
Okefenokee Swamp [8], a dominant in Cumberland Island understories [10],
and common in the Great Dismal Swamp [44] and Big Cypress Swamp [11].
Red bay dominates many everglades tree islands [30,40] and cypress dome
[40] understories. It is occasional in the understories of high
hammocks [2] but a major component in low hammocks. When seen from the
air, southern Florida low hammocks have a characteristic
redbay-dominated tail which extends downstream in the direction of the
everglade's flow [15]. Some southern Florida tree islands are so
dominated by redbay, sweetbay (Magnolia virginiana), and loblolly-bay
(Gordonia lasianthus) that they are known as "bayheads" [23].

Overstory associates include red maple (Acer rubrum) [36], cabbage
palmetto (Sabel palmetto) [39], spruce pine (Pinus glabra) [25], slash
pine (P. elliottii) [17], loblolly pine (P. taeda) [3], sand pine (P.
clausa) [4], southern redcedar (Juniperus silicicola), loblolly-bay,
cassena (Ilex cassine), titi (Cyrilla racemiflora) [8], sweetbay, and
Atlantic white-cedar (Chamaecyparis thyoides) [24].

Understory associates include hurrahbush (Lyonia lucida), swamp
fetterbush (Leucothoe racemosa), sweetspire (Itea virginica), poor-man's
soap (Clethra alnifolia), coral greenbriar (Smilax Walteri), and wax
myrtle (Myrica cerifera) [8,23].

Wells [42] cited redbay as a dominant in his classification system of
Coastal Plain community types.

More info for the terms: competition, natural

The primary mode of regeneration for redbay is sexual. The flowers are
insect- and wind-pollinated. Songbirds, wild turkeys, northern
bobwhites, black bears, and white-tailed deer disperse seeds. Natural
stands of redbay are patchy and diffuse due to overstory competition
[5].

Taxonomy

provided by Fire Effects Information System Plants
The currently accepted scientific name for redbay is Persea borbonia
(L.) Spreng. (Lauraceae). Morphological variety complicates redbay
taxonomy. Three varieties, also regarded as separate species, are
distinguished based on habitat differences and the morphology of the
hair on the undersides of the leaves:

P. b. var. borbonia - typical variety

P. b. var. humilis (Nash) Kopp [P. humulis Nash] - commonly known as
silkbay; distinguished from the typical variety by especially dense hair
[12]; restricted to the oak (Quercus spp.)-pine (Pinus spp.) scrub of
peninsular Florida [4].

P. b. var. pubescens (Pursh) Little [P. palustris (Raf.) Sarg.] - commonly
known as swampbay; distinguished from the type by crooked hair [13] and
an affinity for swampy areas [12,20].

This review follows Little [29] and Kartesz and Kartesz [22] who favor
three varieties. There are no recognized subspecies or forms.

Associated Forest Cover

provided by Silvics of North America
In the forest cover type Sweetbay-Swamp Tupelo-Redbay (Society of American Foresters Type 104), redbay is a major component (1). Stocking within this type may consist of combinations of any two or all three of these species, but locally a single species may dominate. It is a common associate of the following cover types: Loblolly Pine-Hardwood (Type 82), Pond Pine (Type 98), Baldcypress-Tupelo (Type 102), and Water Tupelo-Swamp Tupelo (Type 103). Redbay is a minor component of the following cover types: Cabbage Palmetto (Type 74), Loblolly Pine (Type 81), Atlantic White-Cedar (Type 97), Pondcypress (Type 100), and Baldcypress (Type 101).

Numerous species that grow on moist to wet sites may be associated with Sweetbay-Swamp Tupelo-Redbay, depending on the geographic location, site, and stand history. Common hardwoods include red maple (Acer rubrum), black tupelo (Nyssa sylvatica), loblolly-bay (Gordonia lasianthus), sweetgum (Liquidambar styraciflua), water oak Quercus nigra), laurel oak (Q. laurifolia), yellow-poplar (Liriodendron tulipifera), and southern magnolia (Magnolia grandiflora). Associated conifers include slash pine (Pinus elliottii), longleaf pine (P. palustris), loblolly pine (P. taeda), pond pine (P. serotina), baldcypress (Taxodium distichum), pondcypress (T distichum var. nutans), and Atlantic white-cedar (Chamaecyparis thyoides). Small trees and shrubs associated with redbay include buckwheat-tree (Cliftonia monophylla), dahoon (Ilex cassine), yaupon (I. vomitoria), inkberry (I. glabra), lyonia fetterbush (Lyonia lucida), bayberry (Myrica spp.), and poison-sumac (Toxicodendron vernix).

Silvics of North America

Climate

provided by Silvics of North America
Redbay grows in a climate ranging from warm-temperate along the Atlantic Coast to semitropical in southern Florida and the lower gulf coast of Texas. The frost-free period varies from a minimum of 200 days to a maximum of 365 days and is more than 250 in much of its range. Average January temperatures of these coastal areas range from 3° C (38° F) in southern Delaware to 20° C (68° F) in south Florida, with 10° to 13° C (50° to 56° F) characteristic of most of this region. Summers are hot and humid. Average July temperatures range from 26° to 28° C (78° to 82° F). Temperatures above 38° C (100° F) or below -12° C (10° F) seldom occur over most of this species range.

Average annual rainfall within the natural range of redbay varies from a low of 1020 mm (40 in) in southern Delaware increasing to about 1320 mm (52 in) along the Atlantic coast of Florida and reaches a maximum of 1630 mm (64 in) in several areas along the gulf coast. Rainfall is quite well distributed, with about 55 percent of the total annual rainfall occurring in the warm season (April through September). Periodic summer droughts are more common in the western part than in the rest of this species range (9).

Damaging Agents

provided by Silvics of North America
Fire may cause substantial damage to redbay. Fire scarring with the associated deterioration of the butt portion of the tree is common. It may also prevent or forestall the establishment of reproduction.

Insects or diseases apparently do not cause serious damage to redbay. It is the principal host of Trioza magnoliae, a psyllid or jumping plant louse. This psyllid forms large, unsightly galls on redbay leaves but apparently causes little damage to the tree because a large proportion of the leaves remain unaffected (6). A leaf spot of redbay caused by the fungus Phyllachora perseae has been reported. Evidently this disease is not a serious problem because only a portion of the leaf area is affected (5).

Although some species of the genus Persea are susceptible to a root disease caused by the fungus Phytophthora cinnamomi, redbay is resistant. This resistance is due to a borbonol, a preformed antifungal substance that is a component of the roots and stems of certain species of Persea. Some species of this genus, including several avocado cultivars highly susceptible to this root disease, do not contain antifungal compounds with the properties of borbonol (10).

Flowering and Fruiting

provided by Silvics of North America
The flowers are perfect, appearing in the spring in the axils of the new foliage. Insects, primarily bees, are the principal pollination vector; however, pollen is also disseminated by wind. The fruit is a small drupe about 13 mm (0.5 in) long that is bright blue or blue-black when ripe. A thin layer of rather dry flesh surrounds the seed or pit of the fruit (4).

Growth and Yield

provided by Silvics of North America
Redbay is included in a list of commercial trees of southern hardwood forests, but its growth or the size it attains varies considerably over its range. Presumably these differences in growth are a reflection of variation in site quality (8).

One source (4) describes redbay as a beautiful evergreen tree, sometimes 18 to 21 m (60 to 70 ft) in height and 61 to 91 cm (24 to 36 in) in diameter. Under forest growth conditions it develops a clear, cylindrical bole and a dense, pyramidal crown with ascending branches.

A second source (3) describes redbay as a small evergreen tree seldom more than 9 to 15 m (30 to 50 ft) tall with a trunk diameter of 31 to 61 cm (12 to 24 in). Redbay found growing in the pocosins along the Atlantic Coast has been described as a shrub.

Reaction to Competition

provided by Silvics of North America
Redbay is classed as tolerant of shade but is also found growing well in the open, and in both young and old forest stands. Reproduction is generally erratic and scattered in groups among swamp tupelo and sweetbay. Overstory competition may account for the scarcity and poor form of redbay growing under certain forest conditions (8).

Soils and Topography

provided by Silvics of North America
Redbay is found growing on the borders of swamps and swampy drains in the rich, moist, mucky soil of the lower Coastal Plain. Such muck swamps are not of alluvial origin but generally originate from impoundment of water in land-locked depressions. The water of these swamps is usually dark brown from accumulated organic matter. The bottoms of the swamps do not provide firm support. Sites similar to the deep muck swamps are found in the shallow ponds, strands, and pocosins in the longleaf, slash, and pond pine woods but here tree growth is usually stunted (8). These soils are most commonly found in the order Histosols.

Special Uses

provided by Silvics of North America
The wood is heavy, hard, strong, and bright red, with a thin, lighter colored sapwood, but it has no established place in commerce. It is used locally for cabinet making and interior finish and for boatbuilding. Dried leaves of redbay make an excellent substitute for those of the tropical bay and may be used in the same way for seasoning food. The tree is occasionally used as an ornamental because of the evergreen leaves and its fruit.

Redbay is reported to be of significant importance to wildlife. The fruit is eaten by several species of songbirds and wild turkey. In order of volumetric importance, the redbay fruits were in 15th place in a list of 63 food items. Redbay seeds may form a sizable portion of the bobwhite diet during the fall and winter months. The fruits and leaves of redbay are eaten by deer. It is browsed heaviest in fall and winter but withstands such grazing well. As much as 40 percent of the annual growth has been removed as browse for 2- or 3-year periods without causing death of the plants. Reports that black bear consume both the fruits and leaves of redbay have been noted in North Carolina and Florida (2).

Vegetative Merkmale

Persea borbonia wächst als immergrüner, kleiner Baum oder großer Strauch.

Die wechselständig am Zweig angeordneten Laubblätter sind in Blattstiel und Blattspreite gegliedert. Die Laubblätter riechen aromatisch, wenn sie zerrieben werden.[2] Die einfache Blattspreite ist bei einer Länge von 7 bis 15 Zentimetern (3 bis 6 in) lanzettlich.[3] Die Blattspreiten variieren in der Farbe von hell- bis dunkelgrün.

Generative Merkmale

Die relativ kleine Steinfrucht ist bei Reife blau oder schwarz.[4]

Ökologie

Laubblatt mit den Fraßspuren der Miniermotte Phyllocnistis hyperpersea

Wegen einer Invasion des Borkenkäfers Xyleborus glabratus in den Südstaaten der USA stirbt Persea borbonia vielleicht langsam aus. Dieser Borkenkäfer wurde 2002 nahe Savannah (Georgia) erstmals beobachtet. Er überträgt eine durch den Pilz Raffaelea lauricola hervorgerufene Krankheit, die sogenannte „Lorbeer-Welke“ (englisch laurel wilt), die für das Absterben der Bäume verantwortlich ist.[5]

Einige Förster sind sich jedoch darin einig, dass Persea borbonia nicht aussterben wird, weil sie sich bis zu einem gewissen Grad aus eigener Kraft verjüngen kann.

Hirsche und Bären fressen die Blätter und Früchte von Persea borbonia, Vögel wie Truthühner nur die Früchte.[6]

Natürliches Verbreitungsgebiet

Verbreitung

Persea borbonia wächst an den Küsten der südöstlichen Vereinigten Staaten in den Tiefländern von Texas, Arkansas, Louisiana, Florida, Mississippi, Alabama, Georgia, South Carolina, und Ost-North Carolina. Kleine, isolierte Populationen finden sich an den Küsten von Virginia sowie nahe der Grenze zwischen Maryland und Delaware.[3] Sie wächst auch auf den Bahamas und wird auf Hawaii kultiviert.[7] Normalerweise wächst sie an den Rändern von Brüchen.

Taxonomie

Die Erstveröffentlichung erfolgte 1753 unter dem Namen (Basionym) Laurus borbonia durch Carl von Linné in Species Plantarum, 1, Seite 370.[8] Die Neukombination zu Persea borbonia (L.) Spreng. wurde 1825 durch Kurt Polycarp Joachim Sprengel in Systema Vegetabilium, editio decima sexta, 2, Seite 268 veröffentlicht.[8] Weitere Synonyme für Persea borbonia (L.) Spreng. sind: Persea littoralis Small, Tamala borbonia (L.) Raf., Tamala littoralis (Small) Small.[8][1]

Nutzung

Persea borbonia wird als Zierpflanze für Gärten und Parks verwendet.

Persea borbonia wird nicht mehr sehr als Heilpflanze genutzt. Die Seminolen nutzten sie früher als Brechmittel.[9] Die getrockneten Laubblätter können als Würzmittel verwendet werden.

Das Holz ist hart und haltbar und kann zum Bootsbau, zur Täfelung und zum Fußbodenbau genutzt werden.[9] Es wird nicht im großen Maßstab gehandelt, so dass seine Verwendung auf das Verbreitungsgebiet von Persea borbonia beschränkt ist.

Forschung

Persea borbonia war im Zusammenhang mit Pfropfung und Hybridisierung mit Avocado (Persea americana) Forschungsobjekt. Es sollten mögliche Vorteile für die Resistenz gegen Krankheiten und die Toleranz gegenüber feuchten Böden und kühlen Temperaturen ermittelt werden. Beide Arten bilden wenn überhaupt, dann selten Hybride miteinander. Zur Pfropfung gab es zwei kompatible Gruppen von Persea americana und Persea borbonia, die aber keine lebensfähigen Exemplare hervorbrachten.[10][11]

Persea borbonia

provided by wikipedia EN

Persea borbonia or redbay[3] is a small, evergreen tree in the laurel family (Lauraceae), native to the southeastern United States. It belongs to the genus Persea, a group of evergreen trees including bays and the avocado. Persea borbonia has several common names including tisswood,[3] scrubbay, shorebay, and swampbay.

Description

Persea borbonia can be present as either a small tree or a large shrub. It has evergreen leaves that are about 3 to 6 inches long[4] with a lance shape. The leaves are arranged alternately and emit a spicy smell when crushed.[5] The leaves vary in color from bright green to dark green. These trees are capable of producing fruit that is a small, blue or black drupe.[6] Redbay is a perennial, with a non-herbaceous stem that is lignified.[7]

Distribution

Persea borbonia grows in the coastal margins of the southeastern United States. It is endemic to the lowlands of Texas, Arkansas, Louisiana, Florida, Mississippi, Alabama, Georgia, South Carolina, and eastern North Carolina. Small, isolated populations can be found in coastal Virginia, and near the Maryland and Delaware state line.[8] It also grows in the Bahamas and is cultivated in Hawaii.[9] It usually grows on the borders of swamp land.

Due to an invasion of redbay ambrosia beetle in the Southern United States the tree is slowly dying out. The beetle was discovered in 2002 near Savannah, Georgia and it carries a laurel wilt fungal disease that is responsible for killing redbays.[10] However, foresters agree the species will likely not go extinct in the southeastern U.S. since it appears to rejuvenate to some degree on its own.

Persea borbonia leaf with leaf mines by larvae of the moth Phyllocnistis hyperpersea.

Uses

The plant is not widely used now for medicinal purposes, however members of the Seminole tribe formerly used it as an emetic to induce vomiting.[11] The dried-up leaves can be used as a condiment.[12]

The wood is hard and strong and can be used to build boats, cabinets and for lining the interior of structures. The wood is not traded on a large scale so it is confined to the regions where P. borbonia grows.

Cultivation

Persea borbonia is cultivated as an ornamental tree for gardens and parks.

Wildlife

Deer and bears also eat the leaves and fruits of redbay. Birds, including turkey, eat the plant's bitter fruit.[13][12]

Персея бурбонская, или Красный лавр (лат. Persea borbonia) — вид вечнозелёных растений из рода Персея семейства Лавровые (Lauraceae), распространённых в южных районах Северной Америки, от Техаса до Флориды и Северной Каролины.

Ботаническое описание

Крупный кустарник или небольшое дерево высотой до 20 м, растущее на окраинах болот и в других переувлажнённых местах, нередко по несколько недель находящихся под водой.

Листья кожистые, узкие.

Плоды сухие, размером чуть больше сантиметра.

Одна из разновидностей этого вида, Персея приземистая (Persea borbonia var. humilis), растущая в штате Флорида, является охраняемым растением, поскольку наблюдается серьёзное сокращение её численности из-за проводимого осушения заболоченных участков[3]:191—192.

Применение

Ранее индейцы племени семинолы широко использовали части растения в своей традиционной медицинской практике, для лечения многих недугов, но прежде всего как рвотное и очищающее средство.[4]

Может культивироваться в качестве вечнозелёного декоративного растения, в США культивируется также на Гавайях.

Древесина твердая и прочная, может использоваться для постройки лодок, мебели и декорации помещений. В виду ограниченного распространения растения, его древесина не представлена на глобальном рынке.
