Tsuga caroliniana Engelm.

Comments ( Anglèis )

fornì da eFloras
Tsuga caroliniana is valuable as an attractive ornamental; a number of cultivars have been developed. The wood is of little commercial importance because of the combination of mediocre quality and the relative rarity of the species in nature.

More info for the term: tree

Carolina hemlock is a native, slow-growing, coniferous, evergreen tree
usually 40 to 70 feet (12-21 m) tall and 8 to 12 inches (20-30 cm) in
d.b.h. [4,8,15]. Heights of 150 to 180 feet (46-55 m) and diameters of
5 to 6 feet (1.5-1.8 m) have been reported [8].

Carolina hemlock has a long slender trunk and a narrow crown of slightly
drooping branches. The leaf blades spread from the twig in all
directions. The cones are 1.0 to 1.5 inches (2.5-3.8 cm) long, and the
seeds are the longest of any of the native hemlocks [18]. The bark on
younger trees is flaky and scaly and on older trees, deeply furrowed.
The root system is shallow and spreading [2,6,8].

Habitat characteristics ( Anglèis )

fornì da Fire Effects Information System Plants
More info for the terms: cover, cover type, litter

Carolina hemlock is common on rocky slopes and ridges of the Appalachian
Mountains at elevations between 2,100 and 4,000 feet (400-1,220 m)
[7,8]. Typically, most soils are very acidic (between 3.5-4.5 pH), but
some are near neutral. The heavy, slowly decomposing litter fosters
podzolization as the stand increases in age [7,8].

Other associates of Carolina hemlock in addition to the cover type
species are eastern hemlock (T. canadensis), Carolina silverbell
(Halesia carolina), American holly (Ilex opaca), mountain rosebay
(Rhododendron catawbiense), mountain-laurel (Kalmia latifolia), and oak
(Quercus spp.) [7,8,9].

Zweig mit Nadeln

Die Carolina-Hemlocktanne (Tsuga caroliniana) ist ein Nadelbaum aus der Gattung der Hemlocktannen. Sie wächst in den Vereinigten Staaten in den Appalachen.

Beschreibung

Die Carolina-Hemlocktanne ist ein etwa 15 bis 25 Meter hoher Baum, der einen Brusthöhendurchmesser von 50 bis 60 Zentimetern (maximal 150 Zentimeter)[1] erreicht. Die Borke älterer Bäume ist rau und schuppig, außen rötlich grau und rotbrauner Borke in den Rissen.[2] Die dichte Krone ist kegelförmig, die Äste sind abstehend und oft hängend. Die Triebe sind in den Furchen etwas behaart und glänzend orangebraun, die Knospen eiförmig rundlich.[3]

Die ganzrandigen Nadeln stehen gescheitelt an den Zweigen. Sie werden 15 bis 20 Millimeter lang und 1,5 bis 2,0 Millimeter breit, sind vorne abgerundet oder gestutzt. Die Oberseite ist glänzend dunkelgrün und gefurcht, die Unterseite zeigt zwei auffallende weiße Spaltöffnungsstreifen.[3]

Die Zapfen sind länglich-eiförmig, etwa 2,0 bis 3,5 Zentimeter lang, kurz gestielt oder sitzend. Die Zapfenschuppen sind länglich-eiförmig, abgerundet, dick und außen etwas flaumig behaart. Zur Reife sind sie weit gespreizt.[3] Die Pollen werden zwischen März und April freigesetzt, die Zapfen reifen von Ende August bis Ende September des folgenden Jahres, die Samen werden ab September über den Winter ausgesetzt.[1]

Die Chromosomenzahl beträgt 2n = 24.[4]

Verbreitung, Ökologie und Gefährdung

Das Verbreitungsgebiet der Art befindet sich im östlichen Nordamerika und erstreckt sich entlang der Appalachen[5] von Virginia über Tennessee, South Carolina, North Carolina bis ins nördliche Georgia.[6][7]

Die Carolina-Hemlocktanne wächst auf trockenen, felsigen Hängen[6] in 750 bis 1200 Metern, seltener ab 600 und bis 1500 Metern Höhe[5] auf durchlässigen, sauren bis neutralen, sandig- oder kiesig-humosen, mäßig nährstoffreichen, kalkarmen Böden. Man findet sie an sonnigen bis lichtschattigen Standorten.[3] Die jährliche Niederschlagsmenge übersteigt 1000 Millimeter und fällt über das ganze Jahr.[5]

In der Roten Liste der IUCN wird die Carolina-Hemlocktanne als nicht gefährdet („Lower Risk/least concern“) geführt. Es wird jedoch darauf hingewiesen, dass eine neuerliche Überprüfung der Gefährdung nötig ist.[8]

Systematik

Die Carolina-Hemlocktanne (Tsuga caroliniana) ist eine Art der Gattung der Hemlocktannen (Tsuga). Dort wird sie der Untergattung Tsuga zugeordnet.[9] Das Artepitheton caroliniana verweist auf die beiden US-Bundesstaaten North Carolina und South Carolina.[2]

Verwendung

Das Holz wird aufgrund der Seltenheit der Art und der mittelmäßigen Qualität selten verwendet,[1] die Art ist jedoch als Parkbaum und Heckenpflanze beliebt. In Mitteleuropa ist sie winterhart.[6]

Tsuga caroliniana ( Anglèis )

fornì da wikipedia EN

Tsuga caroliniana, the Carolina hemlock,[3] is a species of hemlock endemic to the United States. As of 2023, it is under review for listing under the Endangered Species Act of 1973.[4]

Distribution and habitat

Carolina hemlock is native to the Appalachian Mountains in southwest Virginia, western North Carolina, extreme northeast Georgia, northwest South Carolina, and eastern Tennessee.[5] Its habitat is on rocky mountain slopes at elevations of 700–1,200 m (2,300–3,900 ft). The optimal growing condition is a partly shady area with moist but well-drained soil in a cool climate.[6] There is a small, self-sustaining population of Carolina hemlock in the Virginia Kendall State Park Historic District of the Cuyahoga Valley National Park in northeast Ohio planted originally as part of reforestation efforts during the park’s development in the 1930s and 40s.[7]

Description

It is an evergreen coniferous tree growing up to 30 m (98 ft) (exceptionally 34 m or 112 ft) tall and 110 cm (43 in) in trunk diameter under forest conditions. The crown is compact and pyramidal, growing up to 8 m (26 ft) wide. The bark is thick and reddish-brown, and becomes fissured between scaly ridges. The branches are stout and usually horizontal, but often slightly drooping. The shoots are red-brown to orange-brown, and finely hairy. The leaves are 5–20 mm (0.20–0.79 in) long and 1.8–2 mm (0.071–0.079 in) broad, flattened, not tapering toward their ends, with a rounded or slightly notched apex; they radiate outward in all directions from the twigs, and smell of tangerine if crushed. They are glossy dark green above and paler on the underside, with two white stomatal bands. The cones are 2–4 cm (0.79–1.57 in) long, green, maturing light to mid-brown 6–7 months after pollination. When fully open, their scales are positioned at a right angle or reflexed to the central axis.[6][8][9]

Threats

The hemlock woolly adelgid (Adelges tsugae), an adelgid introduced to the United States from Asia in 1924, threatens Carolina hemlock, which is as susceptible as the related eastern hemlock.[8] The trees may also be attacked by elongate hemlock scale (Fiorinia externa).[7]: 15–16 [10]

Horticulture

Carolina hemlock is used more often as an ornamental tree than for timber production, due to its overall rarity.[9] In landscaping, it is similar in appearance to eastern hemlock, but the Carolina hemlock has a deep taproot, compared with the shallow, aggressive roots of eastern hemlock. This means shrubs and other plants can be grown more easily under Carolina hemlock.[11]

Tsuga caroliniana, la tsuga de Carolina,[2]​es una especie arbórea perteneciente a las coníferas Pinophyta, originaria de los montes Apalaches en el suroeste de Virginia, oeste de Carolina del Norte, extremo noreste de Georgia, noroeste de Carolina del Sur, y este de Tennessee.[3]​ Su hábitat se encuentra en las laderas rocosas de montaña a alturas de 700-1200 m. La condición de crecimiento óptimo es una zona parcialmente umbría con suelo húmedo pero bien drenado en un clima fresco.[4]

Es una conífera siempreverde que crece hasta 30 m (excepcionalmente 34 m) de alto y 110 cm en diámetro de tronco en condiciones forestales. La copa es compacta y piramidal, que crece hasta 8 m de ancho. La corteza es gruesa, de pardo rojizo y se va fisurando entre las crestas escamosas. Las ramas son rígidas y usualmente horizontales, pero a menudo ligeramente caídas. Los brotes son pardo rojizo a pardo anaranjado con una fina vellosidad. Las hojas tienen 5-20 mm de largo y 1,8–2 mm de ancho, son aplanadas, con una punta redondeada. Los estróbilos tienen 2-4 cm de largo, verdes, cuando maduran son de pardo claro a medio 6–7 meses después de la polinización. Cuando están totalmente abiertos, sus escamas se encuentran en ángulo recto o flexionados respecto al eje central.[4][5][6]

Tsuga caroliniana se usa más como árbol ornamental, debido a su rareza.[6]​ En paisajismo, es parecido en apariencia a la Tsuga de Canadá, pero la especie caroliniana tiene una profunda raíz primaria, en comparación con las raíces agresivas y superficiales de la canadensis. Esto significa que los arbustos y otras plantas pueden crecer más fácilmente por debajo de la caroliniana.[7]

Rotkohemlokki ( Finlandèis )

fornì da wikipedia FI

Rotkohemlokki (Tsuga caroliniana) on mäntykasvien (Pinaceae) heimoon kuuluva havupuu. Se kasvaa luonnonvaraisena pienellä alueella Yhdysvalloissa Appalakkien vuoristossa. Kasvupaikkoja ovat vuorenrinteet 750–1200 metrin korkeudessa. Rotkohemlokki voi kasvaa 30 metrin pituiseksi ja 1,5 metrin paksuiseksi.[2]

Rotkohemlokkia käytetään yleisemmin koristepuuna kuin metsätaloudessa. Sitä on kokeiltu Suomessa hyvin vähän.[3]

Pruche de la Caroline ( Fransèis )

fornì da wikipedia FR

Tsuga caroliniana

La Pruche de la Caroline (Tsuga caroliniana ) est un arbre conifère appartenant au genre Tsuga à la famille des Pinaceae.

Habitat

Le Tsuga caroliniana est un conifère originaire des États-Unis où on le retrouve à l'état naturel dans les États de Caroline du Nord, de Caroline du Sud, de Géorgie, du Tennessee et de Virginie. L'arbre apprécie les endroits semi ensoleillés, dont le sol est humide mais bien drainé.

Description

L'arbre est surtout utilisé à titre ornemental. Sa rareté a empêché toute exploitation forestière spécifique. Le conifère atteint généralement une taille de 30 mètres (jusque 34 mètres maximum) et son tronc atteint 1,1 mètre de diamètre en forêt. Sa forme est pyramidale et peut atteindre 8 mètres de large. Le tronc est de couleur brun-rougeâtre et se fissure avec l'âge. Les feuilles sont longues de 10 à 20 mm. Elles sont vert foncé au-dessus et possèdent en plus deux rangées de stomates blancs en dessous.

Le cône de l'arbre mesure entre 25 et 40 mm de long et est de couleur brun clair. Lorsque celui-ci est ouvert, ses écailles sont positionnées à angle droit par rapport à l'axe central du cône.

Fagurþöll ( Islandèis )

Fagurþöll (fræðiheiti: Tsuga caroliniana[2][3][4][5]) er tegund í þallarættkvísl (Tsuga) ættuð frá Appalasíufjöllum í suðvestur Virginíu, vestur Norður-Karólínu, norðaustast í Georgíu, norðvestur Suður-Karólínu og austur Tennessee í Bandaríkjunum.[6] Búsvæði þess eru klettóttar fjallahlíðar í 700 til 1200 metra hæð. Heppileg vaxtarskilyrði eru í hálfskugga með rökum en gljúpum jarðvegi í svölu loftslagi.[7]

Þetta er sígrænt barrtré sem verður að 30 metra hátt (einstaka sinnum 34m) og 110 sm í þvermál út í skógi. Krónan er þétt og pýramídalaga, að 8 m breið. Börkurinn er þykkur og rauðbrúnn, og verður ´sprunginn með hreistruðum hryggjum. Greinarnar eru kröftugar og yfirleitt láréttar, en geta verið lítið eitt drjúpandi. Sprotarnir eru rauðbrúnir til rauðgulbrúnir, og fínhærðir. Barrið er 5 - 20 mm langt og 1,8 til 2 mm breitt, útflatt bogadregin ofan eða næstum þverstýfð, sjaldan lítillega framjaðrað. Þær standa út í allar áttir út frá greinunum, og ilma af tangerínum ef kramdar. Þau eru gljáandi dökkgræn að ofan og á neðra borði ljósari og með tvær hvítar loftaugarákir. Könglarnir eru 2 til 4 sm langir, grænir óþroskaðir og með þroska verða brúnir til ljósbrúnir 6 til 7 mánuðum eftir frjóvgun. Þegar þeir eru fullopnir eru hreisturblöðkurnar hornrétt eða aftursveigðar frá miðju.[7][8][9]

Ullarlúsin Adelges tsugae, var flutt til austur Bandaríkjanna frá Asíu 1924, ógnar fagurþöll, en hún er næm fyrir henni eins og kanadaþöll.[8]

Fagurþöll er meir notuð sem skrauttré en til timburframleiðslu, ekki síst vegna þess hversu sjaldgæf hún er.[9] Í görðum eru þær svipaðar, en fagurþöll er með stólparót, öfugt við yfirborðskenndar og ágengar rætur kanadaþallar. Það þýðir að runnar og aðrar plöntur þrífast betur undir fagurþöll.[10]

Carolinahemlokk ( norvegèis )

fornì da wikipedia NO

Carolinahemlokk (vitenskapelig navn Tsuga caroliniana) er en art av bartrær innenfor hemlokkslekten i furufamilien. Den er en av fire arter som vokser i Nord-Amerika. I USA kalles den Carolina Hemlock

Trærne er middelsstore, gjerne 20-30 meter høye, sjelden inntil 35 meter. Den har kompakt konisk eller pyramideformet trekrone, som er inntil 8 meter bred. barken er tjukk og rød-brun. Greinene er store, og enten horisontalt utstående eller svakt nedoverbøyde. Diameteren på stammen kan nå 1,15 meter.

Nålene er inntil 2 cm lange, og peker til alle kanter. De har avrundet spiss, og lukter mandarin om de knuses. De er mørkegrønne øverst og har to hvite bånd av spalteåpninger på undersiden. Konglene er grønne og 2-4 cm lange, de åpner seg i løpet av et halvår og blir da lyst brune.

Et insekt som kalles Hemlock woolly adelgid (Adelges tsugae) truer bestanden, som nå er avgrenset til Appalachene i sørvestre Virginia, Nord-Carolina og Sør-Carolina, østlige Tennessee, og det nordøstligste Georgia. Den overlapper nord i fjellkjeden med canadahemlokk (Tsuga canadensis).

Tsuga caroliniana ( ucrain )

fornì da wikipedia UK

Поширення, екологія

Країни проживання: Сполучені Штати Америки (Джорджия, Північна Кароліна, Південна Кароліна, Теннессі, Вірджинія). Росте на висоті від 600 м до 1500 м над рівнем моря (зазвичай 750 м — 1200 м), на скелястих, вологих північних чи східних схилах або скелястих грядах, також уздовж струмків в прохолодних ярах. Клімат вологий і прохолодний, відносно теплий на більш низьких висотах, річна кількість опадів перевищує 1000 мм і падає протягом усього року; є багато хмарної погоди у будь-який час року. Це рідкісне і розсіяне дерево, яке росте поодинці, змішується з широколистяними дерев і чагарниками, або в невеликих майже чистих гаях на лише кілька особин.

Морфологія

Дерева до 30 м заввишки, до 150 см діаметра на рівні грудей. Крона конічна, сплощена на старих деревах; гілки першого порядку довгі, стрункі, поширюються по горизонталі. Кора гладка, червоно-коричнева з жовтими бульбашками смоли, з віком стає грубою, лускатою і потрісканою, з фіолетово-сірою зовнішньою корою і червоно-коричневою внутрішньою корою. Вегетативні бруньки довгасті, 3-4 мм. Листки довжиною 10-20 мм, плоскі, але трохи донизу; нижня поверхня сизо, з 2 широкими, помітними смугами, верхня поверхня блискуча зелена. Насіннєві шишки від яйцеподібної до довгастої форми, розмір 2,5-4 × 1,5-2,5 см, вершини округлі, зелені, після дозрівання через 6-7 місяців після запилення від світло- до серединьо-коричневі. 2n = 24.

Використання

Деревина T. caroliniana має аналогічні властивості, що й Tsuga canadensis, але вид набагато рідший, так що його комерційна цінність обмежена. Як декоративне дерево він також менш широко використовується, бо з насіння вирощується досить повільно. Кілька сортів були вирощені, в основному компактні або карликові.

Загрози та охорона

Цей вид живе розрізненими, невеликими підгрупами на прохолодних, вологих або скельних ділянках, де більшість інших (покритонасінних) дерев і чагарників процвітають менш. Вид може бути в небезпеці, якщо зміна клімату змінить ці місця зростання до більш теплих і сухих умов у майбутньому. Цей вид зустрічається в кількох охоронних територіях.
