Fire Ecology ( англиски )

добавил Fire Effects Information System Plants
More info for the terms: fire regime, root crown, seed, top-kill

Drummond's willow sprouts from the root crown following top-kill by fire
[6,21]. Its abundant wind-dispersed seed may be important in colonizing
burned areas.

Fire is relatively infrequent in the meadow and streamside habitats
Drummond's willow occupies. In fact, these riparian areas frequently act
as fire breaks. However, under dry conditions, riparian habitats can
burn severely [11].

Habitat characteristics ( англиски )

добавил Fire Effects Information System Plants
More info for the terms: marsh, organic soils, shrubs

Drummond's willow occurs along the borders of streams, rivers, beaver
ponds, and lakes, and in wet meadows and marshes [6,9]. It grows at
moderate elevations from lower forested and nonforested foothills to
subalpine habitats. It is generally most abundant in subalpine fir
(Abies lasiocarpa)-Engelmann spruce (Picea engelmannii) habitat types
[6,9]. In these cool habitats, it is not restricted to steamsides, but
occupies moist, well-aerated soils of meadows, broad valley bottoms,
side slope seeps, and stream and pond margins [6,9,25]. At lower
elevations it is uncommon, and usually confined to the edges of streams
in sagebrush (Artemisia spp.), Douglas-fir (Pseudotsuga menziesii), or
ponderosa pine (Pinus ponderosa) vegetation zones [6,9]. In a valley in
northwestern Yellowstone National Park dominated by silver sagebrush
(Artemisia cana), Drummond's willow is primarily found within 65 feet (20
m) of the river's edge [30].


Soils: Drummond's willow typically grows on moist, well-aerated mineral
soils [19]. Textures vary greatly from cobbles and gravels immediately
adjacent to waterways to sandy or clay loams in broad valleys [19]. It
often occurs on fine-textured soils of sediment-filled beaver ponds
[44]. Shallow organic soils overlying alluvium may develop on wet,
marshy, sedge-dominated sites [44]. Water tables vary from near the
surface to about 39 inches (1 m) [19,44].

Elevation: Drummond's willow grows at moderate elevations in the
mountains. Elevational ranges for the following western states are
presented below:

from 8,400 to 9,500 feet (2,560-2,896 m) in California [28]
from 4,000 to 7,100 feet (1,220-2,165 m) in nw Montana [6]
from 7,000 to 10,790 feet (2,135-3,290 m) in Utah [43]
from 6,000 to 10,000 feet (1,829-3,049 m) in Wyoming [2,44]

Associates: Associated shrubs include Booth willow, Barclay willow
(Salix barclayi), planeleaf willow (S. planifolia ssp. planifolia),
Geyer willow (S. geyeriana), mountain willow (S. monticola), Wolf willow
(S. wolfii), mountain gooseberry (Ribes montigenum), whitestem currant
(Ribes inerme), bearberry honeysuckle (Lonicera involucrata), thinleaf
alder (Alnus incana ssp. tenuifolia), red-osier dogwood (Cornus
sericea), alder buckthorn (Rhamnus alnifolia), and marsh cinquefoil
(Potentilla palustris) [4,6,9]. Understory associates include bluejoint
reedgrass (Calamagrostis canadensis), beaked sedge (Carex rostrata),
water sedge (C. aquatilis), tufted hairgrass (Deschampsia cespitosa),
Kentucky bluegrass (Poa pratensis), field mint (Mentha arvensis), and
arrowleaf groundsel (Senecio triangularis) [6,9,23,29].

Importance to Livestock and Wildlife ( англиски )

добавил Fire Effects Information System Plants
In the West, all classes of livestock eat willows (Salix spp.), but
cattle probably consume more than others because they tend to frequent
riparian areas [38]. Drummond's willow is palatable to livestock, but its
importance in their diets has not been reported.

Moose consume large amounts of Drummond's willow during the winter, but
use by other ungulates is generally moderate to light. In Glacier
National Park, moose, elk, and white-tailed deer consumption of Drummond's
willow was moderate, light, and practically nil, respectively [36]. In
the Uinta Mountains of Utah, it made up 92 percent of moose winter
browse [31]. Winter consumption by moose in southwestern Montana was
also high [37]. In some areas of Yellowstone National Park,
overbrowsing by moose and elk has stunted Drummond's willow; most plants
do not reach heights above 5 feet (1.5 m) [10,30].

Willows are a preferred food and building material of beaver [1].
Willow shoots, catkins, buds, and leaves are eaten by ducks and grouse,
other birds, and small mammals [2,18]. In Colorado, red-napped
sapsuckers drill wells in the stems and feed on the sap of Drummond's
willow. Heavy drilling can occur, with up to 90 percent of a single
plant's branches containing wells. These wells serve as feeding sites
for other animals such as warblers, hummingbirds, chipmunks, and red
squirrels [15].

simplicity, riparian communities dominated by either willow are
classified as Booth willow types in eastern Idaho, western Wyoming, and
Utah [29,44].

Management considerations ( англиски )

добавил Fire Effects Information System Plants
Drummond's willow provides important streambank protection by effectively
stabilizing soils. Heavy grazing in moist Drummond's willow communities
can lead to soil compaction, streambank sloughing, and damage to willow
plants [6]. Drummond's willow becomes decadent or stunted when
overbrowsed by cattle or wild ungulates. Plants recover relatively
rapidly when browsing is excluded [10,35].

Palatability ( англиски )

добавил Fire Effects Information System Plants
Most willows are palatable to livestock and big game [2,38]. In the
West, willows are generally more palatable to sheep than to cattle and
tend to become more palatable to stock as the growing season advances
[38]. In Oregon, Drummond's willow is highly palatable to livestock, big
game, and beavers [21]. In a Yellowstone National Park study, Drummond's
willow was moderately to highly palatable to elk; however, it was
considered to be slightly less palatable than yellow and sandbar willow
(Salix lutea, S. exigua) [30]. In most areas, it is highly palatable to
moose [31].

Plant Response to Fire ( англиски )

добавил Fire Effects Information System Plants
Top-killed Drummond's willow plants sprout following fire. Quick, hot
fires generally result in numerous sprouts per plant. Slow burning
fires result in fewer sprouts because these fires often burn down into
the roots, reducing Drummond's willow's sprouting ability [6].

Although there is no documentation of Drummond's willow seedling
establishment following fire, other willows have been observed to do so
when moist mineral soils are present [40]. Drummond's willow seeds are
dispersed in the summer, remain viable for only about 1 week, and
require moist mineral soil for germination. Therefore, the degree of
seedling establishment following fire depends upon the season of burn,
on the weather, and on the amount of mineral soil exposed [41].

Regeneration Processes ( англиски )

добавил Fire Effects Information System Plants
More info for the terms: fresh, fruit, litter, root crown, seed

Drummond's willow's primary mode of reproduction is sexual. It produces
an abundance of small, light-weight seeds. Like most willows, it
probably begins seed production at an early age (between 2 and 10 years)
[18]. At maturity, the fruit splits open and releases the seed. Each
seed has a cottony down that aids in dispersal by wind and water [8].
Seeds are dispersed during the growing season and remain viable for only
about 1 week [8]. The seeds contain significant amounts of chlorophyll
and photosynthesis generally begins as soon as the seed is moistened.
Germination occurs within 24 hours of dispersal if a moist seedbed is
reached [8]. Exposed mineral soils are the best seedbed [18].
Germination and/or seedling establishment is inhibited by litter [18].

Vegetative reproduction: Drummond's willow sprouts from the root crown or
stem base if aboveground stems are broken or destroyed by cutting,
flooding, or fire [18]. Detached stem fragments will root if they are
buried in moist soil [18]. This occurs when stem fragments are
transported by floodwaters and deposited on fresh alluvium [3,18].

More info for the term: shrubs

Drummond's willow tends to form relatively stable, long-lived seral
communities that are maintained by seasonal flooding or high water
tables. However, these sites experience successional shifts if water
tables change. If sites become wetter, sedges may replace Drummond's
willow. If they become drier, Drummond's willow may be replaced by upland
shrubs or conifers [18,44].

In northwestern Montana, high-elevation thinleaf and Sitka alder (Alnus
sinuata) are seral to Drummond's willow [6].

Taxonomy ( англиски )

добавил Fire Effects Information System Plants
The currently accepted scientific name of Drummond's willow is Salix
drummondiana Barratt [3,13].

Early taxonomists subdivided Drummond's willow into several species or
varieties. Recent taxonomic treatments, however, have placed these in
synonomy; thus there are currently no recognized subspecies or varieties
[3,13]. Brunsfeld and Johnson [9] reported that plants from eastern
Washington and northern Idaho appear to be clearly distinct at some
taxonomic level, and that further study of the group is needed.

Value for rehabilitation of disturbed sites ( англиски )

добавил Fire Effects Information System Plants
Drummond's willow is recommended for use in revegetating disturbed
riparian areas. It is especially useful for streambank stabilization.
It is usually planted as rooted or unrooted stem cuttings [33].

Drummond's willow stems contain predeveloped root primordia. Stem
cuttings develop roots along the entire length of the buried portion
within about 10 days of planting [33]. Because it roots quickly,
unrooted Drummond's willow cuttings may be planted on sites with
sufficient moisture throughout the growing season to start and maintain
growth [26,33]. Rooted cuttings have higher survival rates than
unrooted cuttings.

Procedures and techniques for collecting, preparing, and planting willow
cuttings are described by Platts and others [33] and McClusky and others
[26].

Salix drummondiana is a species of willow known by the common name Drummond's willow. It is native to western North America from Yukon and the Northwest Territories in the north to California and New Mexico in the south. It is a resident of moist mountain habitats, including forests, riverbanks, and floodplains.

Description

Salix drummondiana is a shrub growing one to five meters tall. Its brittle branches are hairless to velvety when new, becoming waxy and shiny with age. The leaves are lance-shaped to oval and pointed, with smooth or rippled edges that roll under slightly. The leaves are up to 8.5 centimeters long and are woolly on the undersides and hairless to lightly hairy on the top surfaces. New leaves are coated in silky hairs.

The inflorescences are produced before the leaves. Each is a catkin of flowers. Male catkins are 2 to 4 centimeters long, and female catkins can be almost 9 centimeters in length, lengthening further as the fruits develop. This willow primarily reproduces sexually, by seed, but it can also reproduce vegetatively from stem fragments; this often happens when the shrub is broken up by a flood and pieces of the stem are washed away and deposited in a new area.[1]

This willow is an important winter food for moose in many areas, and beavers use it for food and to build their dams.[1]

Salix drummondiana ( шпански; кастиљски )

добавил wikipedia ES

Salix drummondiana, es una especie de sauce perteneciente a la familia de las salicáceas. Es nativa del oeste de Norteamérica desde Yukon y los Territorios del Noroeste en el norte, hasta California y Nuevo México en el sur. Se encuentra en hábitat húmedos de montaña, incluidos los bosques, ríos y llanuras aluviales.

Descripción

Salix drummondiana es un arbusto que alcanza un tamaño de uno a cinco metros de altura. Sus ramas son frágiles con vello aterciopelado cuando son nuevas, son cerosas y brillantes con la edad. Las hojas son lanceoladas u ovales y puntiagudas, con bordes lisos o arrugados. Las hojas miden hasta 8,5 centímetros de largo y son lanosas en la parte inferior y sin pelo a ligeramente peludas en la superficie superior. Las nuevas hojas están recubiertas de pelos sedosos. La inflorescencia se produce antes que las hojas. Cada una es un amento, con los amentos masculinos de 2 a 4 centímetros de largo, y los femeninos que pueden alcanzar casi 9 centímetros de largo. Este sauce, principalmente, se reproduce sexualmente, por semillas, pero también puede reproducirse vegetativamente a partir de fragmentos del tallo, lo que sucede a menudo cuando el arbusto es interrumpido por una inundación y trozos del tallo son arrastrados y depositados en una nueva área.[1]

Ecología

Este sauce es un alimento importante en el invierno para el alce en muchas áreas, y los castores lo utilizan como alimento y para construir sus represas.[1]

Taxonomía

Salix drummondiana fue descrita por Barratt ex Hook. y publicado en Flora Boreali-Americana 2(9): 144, en el año 1838.[2]

Description

Site dominé par Salix drummondiana.

Salix drummondiana est un buisson de un à cinq mètres de haut. Ses branches fragiles vont de glabres à duveteuses quand elles sont jeunes. Elles deviennent cireuses et brillantes avec l'âge. Les feuilles varient d'ovales à lancéolées et sont pointues avec des bords lisses ou ridés. Elles ne dépassent guère 8,5 centimètres de long et sont cotonneuses au-dessous, glabres à légèrement velues au-dessus. Les jeunes feuilles sont recouvertes de poils cotonneux.

Les inflorescences apparaissent avant les feuilles. Les chatons mâles mesurent de 4 cm de long tandis que les chatons femelles peuvent aller jusqu'à 9 centimètres, continuant à s'allonger après l'apparition des fructifications. La reproduction se fait naturellement par les graines mais aussi par morceaux de rameaux brisés par les flots. Les brisures sont alors disséminées par les eaux courantes dans de nouveaux secteurs[2].

Cette espèce fournit de la nourriture en hiver pour les élans dans de nombreuses régions et les castors nord-américains l'utilisent pour construire leurs barrages[2].
