Redberry Juniper

Juniperus coahuilensis (Martínez) Gaussen ex R. P. Adams

Comments

provided by eFloras
Roseberry juniper is unusual in that it sprouts from the stump after burning or cutting. Hybridization with Juniperus pinchotii occurs in Big Bend National Park, Texas (R. P. Adams and J. R. Kistler 1991), and possibly near Saltillo, Mexico. Reports of hybridization with J . ashei have been refuted (R. P. Adams 1975).

Description

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

Redberry juniper is a native, evergreen, small tree or large shrub.
Mature height usually ranges from 12 to 15 feet (3.6-4.5 m), with
spreading and ascending branches forming an open, irregular crown.  The
ovulate cones contain one seed [15].  The bark is shreddy, but but is
formed close to the trunk.  Redberry juniper tends to have a central
erect stem with lower branches originating near the ground level [5].

Fire Ecology

provided by Fire Effects Information System Plants
More info for the terms: fire regime, shrubs

Redberry juniper occurs on juniper savannas, which are kept open by
fire.  Fires in these habitats tend to be surface fires carried by
grasses, which burn so rapidly that heat levels lethal to large redberry
juniper are rarely generated [7].  Fire-free intervals of 10 years or
more are usually sufficient to allow juniper (Juniperus spp.) saplings
to reach fire-resistant size:  about 3 to 6 feet (1-2 m) [22].  Redberry
juniper occurs in evergreen oak woodlands [11] which experience rapidly
burning grass fires approximately every 10 to 20 years [22].

In some areas, junipers (probably including redberry juniper) are
encroaching on grasslands that were historically kept clear of trees and
shrubs by very frequent fires.  Climatic changes and intensive livestock
grazing have also been implicated in this encroachment [7].

Key Plant Community Associations

provided by Fire Effects Information System Plants
More info for the terms: codominant, shrub

In the Southwest junipers (Juniperus spp.) are associated with oaks
(Quercus spp.) and true pinyon (Pinus edulis).  Junipers increase in
dominance over oaks and pinyons on dry sites [14].  Redberry juniper is
common in alligator juniper (J. deppeana)-pinyon woodlands and savannas,
and in areas where its range overlaps with Utah juniper (J.
osteosperma), oneseed juniper (J. monosperma), and Rocky Mountain
juniper (J. scopulorum) [8].  It occurs in evergreen oak woodlands with
Emory oak (Q. emoryi) and Mexican blue oak (Q. oblongifolia) [11].
Redberry juniper is also found in Arizona chaparral woodlands with shrub
live oak (Q. turbinella) and Arizona rosewood (Vauquelinia californica)
[20].  It occurs as scattered individuals in grama (Bouteloua spp.)
grasslands, along with scattered velvet mesquite (Prosopis velutina),
Mexican blue oak, and alligator juniper [14].

Regeneration Processes

provided by Fire Effects Information System Plants
More info for the terms: seed, top-kill

Redberry juniper reproduces by seed.  Further information specific to
reproduction in redberry juniper is not available.  Pinchot juniper is
one of the few juniper species known to sprout after top-kill, and it is
closely related to redberry juniper.  In most junipers germination may
be delayed up to 2 years through embryo dormancy, seedcoat
impermeability, or chemical inhibitors.  Juniper seedling establishment
is enhanced by light shade, which helps maintain adequate moisture [7].

Taxonomy

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

The currently accepted scientific name for redberry juniper is Juniperus coahuilensis
(Martinez) Gaussen [10,26,27]. Confusion about the correct name for this entity arose
over its morphological resemblance to oneseed juniper (J. monosperma) and over its red
cones, which resemble those of Pinchot juniper (J. pinchottii). Redberry juniper
intergrades with Pinchot juniper in the Trans-Pecos region of Texas, where their
ranges overlap. There is a probable hybrid swarm in the Basin of the Chisos Mountains,
Texas [1,14]. Zanoni and Adams [24] determined that redberry juniper and Pinchot
juniper are the most closely related junipers based on similarity of leaf oil
terpenoids and other characters.

Rotbeeren-Wacholder ( German )

provided by wikipedia DE

Der Rotbeeren-Wacholder (Juniperus coahuilensis) ist eine Pflanzenart aus der Familie der Zypressengewächse (Cupressaceae). Er ist im Süden der USA sowie in Nord-Mexiko heimisch.

Beschreibung

Der Rotbeeren-Wacholder wächst als immergrüner Strauch oder Baum, der Wuchshöhen von bis zu 8 Meter und Brusthöhendurchmesser von bis zu 1 Meter erreichen kann. Als Baum ist er einstämmig, während sich die Strauchform bereits am Boden verzweigt. Die Äste gehen gerade oder aufsteigend vom Stamm ab und bilden eine flach-kugelige bis unregelmäßige Krone. Die graue bis braune Borke blättert in langen Streifen ab. Die Rinde der dünneren Zweige ist glatt, während die von dickeren Zweigen in Streifen oder gelegentlich auch in Flocken abblättert.[1]

Die Art bildet zwei verschiedene Arten von Nadeln aus. Die grünem bis hellgrünen, schuppenartigen Blätter erreichen eine Länge von 1 bis 3 Millimeter. Sie sind gekielt und ihre Spitze ist spitz zulaufend. Sie überlappen sich nie oder nur bis zu einem Viertel ihrer Gesamtlänge. Die begeißelten Nadeln sind an der Nadeloberseite blaugrün gefärbt und werden 4 bis 6 Millimeter groß. Alle Nadeln haben gezähnte Blattränder und an ihrer Unterseite findet man elliptische oder eiförmige Drüsen von denen einige ein auffällig weiße, kristalline Flüssigkeit absondern.[1]

Der Rotbeeren-Wacholder ist zweihäusig-getrenntgeschlechtlich (diözisch) und die Zapfen reifen nach einem Jahr. Die beerenförmigen Zapfen stehen an geraden Stielen und sind bei einer Größe von 6 bis 7 Millimeter kugelig bis eiförmig geformt. Zur Reife hin sind sie rosa, gelborange, orange oder dunkelrot gefärbt und werden von einer blaugrünlichen Schicht bedeckt. Jeder der fleischigen und süß schmeckenden Zapfen trägt ein bis zwei Samenkörner. Die Samen erreichen eine Länge von 4 bis 5 Millimeter.[1]

Verbreitung und Standort

Das natürliche Verbreitungsgebiet des Rotbeeren-Wacholder liegt im Süden der USA sowie im Norden Mexikos. Es umfasst in den USA die Bundesstaaten Arizona, New Mexico und das südwestliche Texas. In Mexiko findet man die Art nur im Bundesstaat Coahuila.[1]

Der Rotbeeren-Wacholder gedeiht in Höhenlagen von 980 bis 2200 Metern. Man findet die Art vor allem in Grassteppen sowie auf daran angrenzenden, felsigen Berghängen. Vor allem in Arizona kommt es zur Bildung von Mischbeständen mit dem Utah-Wacholder (Juniperus osteosperma). Als weitere vergesellschaftete Arten können Opuntien (Opuntia) sowie Palmlilien (Yucca) auftreten.[1]

Nutzung

Früher wurde das Holz zur Herstellung von Zaunpfählen genutzt.[2]

Systematik

Die Erstbeschreibung als Juniperus erythrocarpa var. coahuilensis erfolgte 1946 durch Maximino Martínez in Anales del Institutó de Biología de la Universidad Nacional Autonoma de México, Série Biologia, Band 17, Nummer 1, Seite 115–116. Henri Marcel Gaussen beschrieb die Varietät im Jahr 1968 in Travaux du Laboratorie Forestier de Toulouse, Nummer 1(2/10), Seite 154 als eigenständige Art Juniperus coahuilensis.[3]

Die Art wird in zwei Varietäten unterteilt:[3]

  • Juniperus coahuilensis var. arizonica R.P.Adams kommt in Arizona, New Mexico, Texas und im mexikanischen Bundesstaat Sonora vor.[1][4] Eine von Robert Phillip Adams im Jahr 2006 veröffentlichte Arbeit stützt mithilfe von DNA-Analysen die Annahme, dass die Varietät als eigenständige Art Juniperus arizonica R.P.Adams angesehen werden sollte.[5]
  • Juniperus coahuilensis var. coahuilensis ist die Nominatform und kommt vom südwestlichen Texas bis ins nordöstliche Mexiko vor.[1][4]

Im Big-Bend-Nationalpark sowie wahrscheinlich in der Nähe von Saltillo kommt es zur Hybridbildung mit Juniperus pinchotii.[1]

Gefährdung und Schutz

Der Rotbeeren-Wacholder wird in der Roten Liste der IUCN als „nicht gefährdet“ geführt. Die Varietät arizonica wird ebenfalls als „nicht gefährdet“ gelistet. Beide Varietäten kommen häufig vor und die Bestände scheinen sich zu vergrößern.[2][6]

Juniperus coahuilensis

provided by wikipedia EN

Juniperus coahuilensis, commonly known as redberry juniper, is a species of conifer in the family Cupressaceae.[2]

Description

Juniperus coahuilensis grows as a large shrubby tree up to 8 metres (26 feet) tall. It is usually multi-trunked.[3] The bark is brown to gray, exfoliating in long strips on mature trunks and branches.[3]

The leaves are green to light green, and have glands that can produce a white crystalline exudate.[3]

The cones are a fleshy glaucous yellow-orange to dark red, 6–7 millimetres (14932 in) in diameter, and mature in one year.[3]

This species is unusual in that it sprouts from the stump when cut or burned, which has probably allowed it to remain in the grasslands in spite of periodic grass fires that kill all other juniper species.[4]

Fossil record

The species is known to have been present during the Late Wisconsin Glacial Episode of the last glacial period, in North American latitudes defined by fossils from the Waterman Mountains in present-day Arizona.[5]

Distribution

The shrubby tree is found in northern Mexico and areas of the Southwestern United States within central and southeastern Arizona, southwestern New Mexico, and West Texas including Big Bend National Park.[3]

This species occurs in high desert grasslands at elevations of 1,200–2,000 m (3,900–6,600 ft), in Bouteloua spp. grasslands and adjacent rocky areas.[1] In Mexico, it can also occur in canyons or alluvial fans. In the Chihuahuan Desert and Sonoran Desert ecoregions, it often in association with Opuntia spp. and/or Yucca spp.[4]

Таксономічні примітки

Juniperus coahuilensis var. arizonica раніше був включений в цей вид, а в даний час визнається як окремий вид (Farjon 2010).

Поширення, екологія

Країни зростання: Мексика (Чіуауа, Коауїла, Дуранго, Наяріт, Тамауліпас, Сакатекас); США (Техас). Цей вид зустрічається в високогірній пустелі (1200–2000 м над рівнем моря), на луках і в прилеглих скелястих районах. Він незвичайний тим, що J. coahuilensis пускає пагони з пня, коли вирізати або спалити. Ця особливість, ймовірно, дозволяє йому залишатися на луках, незважаючи на періодичні трав'яні пожежі, які вбивають всі інші види ялівцю.

Морфологія

Чагарники або дводомні дерева, до 8 м, стовбур один; крона від плоско-кулястої до нерівної й до кулястої. Кора від сірого до коричневого кольору, лущиться на довгі рвані смуги. Гілки від розлогих до висхідних. Листки від зеленого до світло-зеленого кольору; батогоподібні листки 4-6 мм, сизо зверху; лускоподібні листки 1-3 мм з гострою вершиною. Шишки зріють 1 рік, від кулястих до яйцеподібних, 6-7 мм, трояндового кольору але жовто-оранжеві, оранжеві або темно-червоні під сизим покриттям, м'ясисті й дещо солодкуваті, з 1 (- 2) насінням. Насіння 4-5 мм.

Використання

Комерційне використання не відоме цього виду.

Загрози та охорона

Здається, немає ніяких загроз для цього виду, хоча надмірний випас в Мексиці може бути проблемою в деяких областях. Ялівець присутній в кількох ПОТ в США, у Мексиці — ні.
