TAXONOMY:
The currently accepted scientific name of Geyer willow is Salix
geyeriana Anderss. [15,34].

Hitchcock and Cronquist [27] recognize two varieties of Geyer willow:
var. geyeriana and var. meliana Henry. However, recent research in
Idaho has shown that plants designated as var. meliana more closely
match descriptions of Lemmon willow (S. lemmonii) than they do Geyer
willow [9]. Proper identification can be difficult when the two species
grow near each other. In Idaho, these two species are morphologically
and ecologically distinct, but in areas of contact, identification is
complicated by hybridization [9]. Geyer willow may also hybridize with
Sitka willow (S. sitchensis) in British Columbia [6].

Fire Management Considerations

provided by Fire Effects Information System Plants
Prescribed fire can be used to rejuvenate decadent Geyer willow [5].
Following fire, 5 or more years are required before stems reach
browse-resistant size [30].

Geyer willow often occurs in wet, poorly drained marshes or swamps.
These sites are difficult to burn until they become dry in the late
summer or fall [30].

Key Plant Community Associations

provided by Fire Effects Information System Plants
More info for the terms: forbs, mesic

Geyer willow commonly dominates shrubby communities associated with
lower, middle, and upper elevation mountain streams and meadows
[23,30,44,54]. These communities have an "open and clumpy appearance"
or an "open, corridor-like structure". Large patches of Geyer willow
form the overstory, with lesser amounts of shrubby willow species
intermixed in the openings. Willow associates include Booth willow
(Salix boothii), yellow willow (S. lutea), Bebb willow (S. bebbiana),
planeleaf willow (S. planifolia ssp. planifolia), Drummond willow (S.
drummondiana), and Lemmon willow [5,30,54]. The undergrowth
is often dense, and dominated by sedges (Carex spp.), bluegrasses (Poa spp.), tufted
hairgrass (Deschampsia caespitosa), bluejoint reedgrass (Calamagrostis
canadensis), or mesic forbs [24,30,44,54].

Management considerations

provided by Fire Effects Information System Plants
Geyer willow communities are open and easily accessible, and produce
large amounts of forage. They are often heavily used by stock when
nearby uplands become dry [25]. Many Geyer willow communities have a
long history of overgrazing, which has resulted in the replacement of
native grasses and sedges with bluegrasses [30]. Overuse also results
in soil compaction, streambank sloughing, and damage to willows and
other vegetation [24]. Prolonged overbrowsing of Geyer willow results
in poor vigor and decadence, indicated by uneven stem age distribution,
a hedged or clubbed appearance, and dead plants [30]. Decadent plants
will recover from overbrowsing with 5 to 6 years of rest [30].

Salix geyeriana

provided by wikipedia EN

Salix geyeriana is a species of willow known by the common names Geyer's willow, Geyer willow and silver willow.[4][11] The type specimen was collected by the botanist Karl Andreas Geyer, for whom it was named.[1] Its conspicuous, yellow flowers begin to bloom as early as March, to as late as the end of June.[2][12]

Description

Salix geyeriana is a shrub growing up to 5 m (16 ft) tall, sometimes forming dense colonial thickets. The leaves are narrowly or widely lance-shaped and may grow over 7 cm long. Young leaves are coated in white or pale silky hairs, and some adult leaves retain their hairy textures. The leaves generally lack stipules or have only vestigial ones. The inflorescence is a spherical or slightly elongated catkin usually not more than about 2 cm long.

This species reproduces sexually by seed, as well as vegetatively, by sprouting from the stem or sections of the stem, which contain early root structures that readily sprout when buried in moist substrate.[11]

Habitat

S. geyeriana grows in moist and wet habitat types, such as lakesides, riverbanks, and bogs.[2][11]

Distribution

S. geyeriana is native to western North America. It is distributed from western Canada in southern British Columbia; through the US in Washington; central Idaho; western Montana and Wyoming; eastern Oregon; Nevada; and northern Utah; to southern and western Colorado; through central California; eastern and central Arizona; and western New Mexico. It is found in the Great Basin region, and in the mountains in the High Cascades, the Rockies, the northern and southern High Sierra Nevada, and the San Bernardino Mountains. Populations are especially dense over the Kern Plateau.[2][3][4][11][13]

Hybrids

The lack of stipules and small, stubby catkins help identify this species; however, it easily hybridizes with many other willows in the wild; the daughter plants differ in morphology.[2]

The most widely distributed natural hybrid is S. geyeriana × S. lemmonii. It is known from British Columbia (in the vicinity of Victoria), Oregon (in Jefferson and Lane counties), and California (in Lassen and Sierra counties).[2]

Hybrids with S. bebbiana are known from Montana (collected from Beaverhead County); those with S. pedicellaris are known from Washington; and those with S. irrorata and S. ligulifolia are known from Arizona.[2][14]

Wildlife value

S. geyeriana is browsed in the wild by moose (Alces alces) and elk (Cervus canadensis) in all seasons, but is essential during winter.[11]

Grouse (Phasianidae subf. Tetraoninae), ducks (Anatidae), and other small birds, and small mammals regularly consume the buds, catkins, shoots, and leaves of G. geyeriana; and it is one of many Salix species used in the construction of beaver dams for North American beavers (Castor canadensis).[11]

Salix geyeriana ( Spanish; Castilian )

provided by wikipedia ES

Salix geyeriana es una especie de sauce perteneciente a la familia de las salicáceas.[3][4]​ Sus notables flores amarillas comienzan a florecer a principios de marzo, hasta tan tarde como a finales de junio.[2][5]

Descripción

Salix geyeriana es un arbusto que alcanza un tamaño de hasta 5 metros de altura, a veces formando colonias de densos matorrales. Las hojas son estrechas en forma de lanza y pueden crecer hasta más de 7 centímetros de largo. Las hojas jóvenes están cubiertas de pelos sedosos de color blanco o pálido, y en algunos adultos las hojas conservan su textura peluda. Las hojas generalmente carecen de estípulas o sólo tienen vestigios de ellas. La inflorescencia es un amento esférico o ligeramente alargado por lo general no más de unos 2 centímetros de largo. Esta especie se reproduce sexualmente por semilla, así como vegetativamente, porque brotan del tallo, o sus secciones, ya que contienen las estructuras fundamentales para brotar con facilidad cuando son enterrados en el sustrato húmedo.[4]

Hábitat

S. geyeriana crece en hábitats húmedos y muy húmedos, como orillas de los lagos, ríos y pantanos.[2][4]

Distribución

S. geyeriana es nativa de Norteamérica occidental. Se distribuye desde el oeste de Canadá en el sur de la Columbia Británica, a través de los estados de Washington, el centro de Idaho, el oeste de Montana y Wyoming, este de Oregon, Nevada, y el norte de Utah, al sur y el oeste de Colorado, por el centro de California, este y centro de Arizona, y oeste de Nuevo México. Se encuentra en la región de la Gran Cuenca, y en las montañas en la cordillera de las Cascadas, las Montañas Rocosas, en Sierra Nevada y la Sierra de San Bernardino.[2][6][3][4][7]

Ecología

G. geyeriana es buscada como alimento en la naturaleza por los alces (Alces alces) y (Cervus canadensis) en todas las estaciones, pero es esencial durante el invierno.[4]

Urogallos (Phasianidae subf. Tetraoninae), patos (Anatidae), y otras pequeñas aves y pequeños mamíferos consumen regularmente las yemas, amentos, brotes y hojas de G. geyeriana , y es uno de las muchas especies de Salix utilizadas en la construcción de las represas de castores (Castor canadensis ).[4]

Taxonomía

Salix geyeriana fue descrita por Nils Johan Andersson y publicado en Öfversigt af Förhandlingar: Kongl. Svenska Vetenskaps-Akademien 15(3): 122–123, en el año 1858.[8]

Etimología

El epíteto geyeriana fue otorgado en honor del botánico Carl Andreas Geyer que recogió la especie tipo[1]

Saule de Geyer

Salix geyeriana est une espèce de saule d'Amérique du Nord connue sous le nom de saule de Geyer (en anglais : Geyer's willow) et saule argenté (silver willow)[2],[3].

Le spécimen type a été récolté par le botaniste allemand Karl Andreas Geyer (en), dont on a donné le nom à l'espèce[1]. Ses fleurs jaunes commencent à apparaître de début mars à la fin juin, suivant les régions[4],[5].

Description

Salix geyeriana est un buisson atteignant 5 m de haut, formant parfois de véritables bosquets. Les feuilles sont plus ou moins lancéolées et peuvent mesurer plus de 7 cm de long. Les jeunes feuilles sont couvertes d'une pilosité blanche ou pâles, certaines feuilles adultes conservant cette texture. Elles perdent généralement leurs stipules ou en conservent seulement des vestiges. L'inflorescence est un chaton sphérique ou légèrement allongé qui ne fait guère plus de 2 cm de long. L'espèce se reproduit par semis naturel aussi bien que par marcottage de sections de racines que la moindre humidité conduit à s'enraciner[3].

 src=
Détail des chatons.

Habitat

Salix geyeriana se plait en tous lieux humides, bords de lacs, de rivières et marais[4],[3].

Distribution

Salix geyeriana est natif de l'Ouest de l'Amérique du Nord. On le trouve de l'Ouest du Canada, au Sud de la Colombie-Britannique ; aux USA, dans l'État de Washington ; au centre de l'Idaho ; ouest du Montana et le Wyoming ; est de l'Oregon ; Nevada ; et nord de l'Utah ; jusqu'au sud et à l'ouest du Colorado ; le centre de la Californie ; est et centre de l'Arizona ; ouest du Nouveau-Mexique. Il est présent dans la région de Great Basin et dans les montagnes de la chaîne des Cascades, des Rocheuses, nord et sud de la sierra Nevada, et les montagnes de San Bernardino. On trouve de denses populations sur le plateau de Kern et près de la Kern River[4],[6],[2],[3],[7].

Hybridations

S. Monticola en ().

L'absence de stipules et la petitesse des chatons aident à l'identification de l'espèce ; cependant, elle s'hybride facilement avec les autres saules dans la nature mais les plantes parentes différent par leur morphologie[4]. L'hybride naturel le plus fréquent est S. geyeriana × S. lemmonii[4].

Les hybridations avec Salix bebbiana se rencontrent au Montana (Beaverhead); celles avec S. pedicellarisse trouvent dans le Washington ; et celles avec S. irrorata et S. ligulifolia sont rencontrées en Arizona[4],[8].

Plus-value pour la faune

S. geyeriana est répandu dans la nature par les élans (Alces alces) et les wapitis (Cervus canadensis), en toutes saisons mais surtout en hiver[3].

Des Grouses (Phasianidae subf. Tetraoninae), des canards (Anatidae), d'autres petits oiseaux et de petits mammifères se nourrissent de bourgeons, chatons, racines, rameaux et feuilles. C'est par ailleurs une des nombreuses espèces de saule utilisées par les castors (Castor canadensis) pour construire leurs barrages[3].
