Broad-scale Impacts of Plant Response to Fire ( englanti )

tarjonnut Fire Effects Information System Plants
More info for the terms: root crown, seed, severity

Fire severity can affect willow postfire recovery. High-severity fires can damage the roots and rhizomes to the point of no recovery [38]. Following low-severity fires most willows will recover quickly due to the ability of the root crown to send up new roots. Severe fires that destroy the organic soil layer kill willows but can expose the mineral soil necessary for seed propagation [24,38].

Habitat characteristics ( englanti )

tarjonnut Fire Effects Information System Plants
More info for the terms: lichens, root collar, shrubs, tundra

In Alaska and northern Canada, littletree willow is found in both upland and lowland forests. It grows in the open tundra above timberline, along riverbanks and streambanks, and on floodplains. In interior Alaska, it forms dense thickets in riparian habitats, and grows as small shrubs in white spruce (Picea glauca) and black spruce (P. mariana) woodlands and in black spruce muskegs [3,5]. Soils: Littletree willow grows best in deep, moist alluvial bottomlands but is found in a wide variety of substrates. The general pH range of the soil for willows is 5.5 to 7.5 [15]. Growth of littletree willow is reduced when water levels are maintained at or above the root collar for extended periods [15]. Plant associates: Littletree willow is commonly associated with the following species: black spruce, white spruce, paper birch, aspen, resin birch (Betula glandulosa), Cladonia lichens, alder (Alnum crispa and A. tenuifolia), willows (Salix scouleriana and S. bebbiana), grasses (Calamagrostis canadensis and Carex species), mosses (Polytrichum spp.), and herbs (Epilobium spp.) [4,26,37].

Importance to Livestock and Wildlife ( englanti )

tarjonnut Fire Effects Information System Plants
Littletree willow is an important browse species for moose, deer, caribou, snowshoe hares, beavers, small mammals, and some birds [15,16,28,29,31,42]. In young, seral communities in Alaska, moose in the winter feed primarily on willow shoots, quaking aspen (Populus tremuloides), paper birch (Betula papyrifera), and balsam poplar (Populus balsamifera) [28]. Of these plants, willow is considered the most preferred by moose, and littletree willow the most preferred willow [28,29]. In one study willows accounted for 94 percent of the biomass consumed by radio-collared moose during observed foraging periods, with littletree willow comprising 14 percent of total biomass consumed [32]. Snowshoe hares also utilize Salix spp. a great deal in interior Alaska, occasionally showing a preference for littletree willow [31].

Management considerations ( englanti )

tarjonnut Fire Effects Information System Plants
Littletree willow is an important browse source for moose in Alaska.
When assessing moose range conditions only the amount of browsing
sustained by the highly and moderately preferred willow species, such as
littletree willow, should be considered. Where these species are
overutilized, certain nonpreferred species will scarcely be touched by
moose [29].

Plant Response to Fire ( englanti )

tarjonnut Fire Effects Information System Plants
More info for the terms: herbaceous, presence, severity

Littletree willow is one of the most common willows on recent burns in interior Alaska [36]. Invasion by willows after fire depends on the season and severity of fire, weather, and presence of a mineral soil seedbed [38]. In young black spruce stands originating following fire, littletree willow regenerated at about 4,000 to 5,000 stems per acre (9,880-12,350 stems/ha) [27]. The chance of littletree willow establishing years after a fire lessens as the available mineral soil seedbed sites are occupied by the faster growing herbaceous species or mosses [38]. Littletree willow is the dominant species following fire in black spruce communities for 6 to 25 years [38].

Regeneration Processes ( englanti )

tarjonnut Fire Effects Information System Plants
More info for the terms: capsule, fruit, seed

Sexual reproduction: Male and female flowers are borne in catkins on separate plants. The fruit is contained in a capsule that splits in half to release many seeds that are then dispersed by wind or water [15]. Optimum seed production is reached when trees are between 2 and 10 years of age [15]. The flowers are mostly insect pollinated, with bees playing the most important role [11,15]. The seeds of littletree willow are short-lived and nondormant, and germinate immediately on moist surfaces [10,44]. The broad temperature range of germination for these seeds, 41 to 77 degrees Fahrenheit (5-25 deg C), appears to be a compensatory mechanism for the short seed life [10,44]. Germination occurs best in moist, exposed mineral substrates that receive substantial sunlight [15]. Vegetative reproduction: Littletree willow will sprout from the root crown or basal stems [8,16,]. It is also capable of vegetative reproduction by underground rhizomes or roots [38].

More info for the term: fresh

Littletree willow is a common early seral species that will invade fresh alluvium deposits, glacial outwash, and silty-sandy alluvial deposits [1,39]. It is a common species after fire in open stands of black spruce in wet sites, and is one of the most successful colonizers in other types of disturbed areas such as roads, borrow pits, bladed slopes, and mine sites [9,19,36]. Littletree willow can become established during periods of low water on floodplains but are usually swept away by high water later. Once they are well established they can withstand both flooding and silting and can slow down river flow [39]. Littletree willow has low shade tolerance and cannot persist on sites that are heavily forested [39].

Salix arbusculoides ( englanti )

tarjonnut wikipedia EN

Salix arbusculoides is a species of flowering plant in the willow family known by the common name little tree willow.[1] It is native to northern North America, where its distribution extends across Alaska and most of Canada.[2]

This willow is a shrub or tree growing up to 9 meters tall. It has many branches with smooth gray or reddish-brown bark. The leaves are up to 7.5 centimeters long and often have a thin coat of hairs on the undersides.[2] Immature leaves have thicker coats of hair and are paler and yellowish in color. The leaves have toothed edges that are studded with glands that function as resin glands as well as hydathodes.[3] This species is dioecious, with male and female catkins borne on separate individuals. The flowers are pollinated by insects, especially bees.[2]

This plant grows in forests and open meadows. It dominates or codominates willow communities, particularly in interior Alaska and parts of the Northwest Territories. It can grow on the tundra above the timberline. It is often found near rivers and streams and on floodplains, forming dense thickets near water. It can be found in spruce woodlands and muskegs. Associated species include black spruce (Picea mariana), white spruce (Picea glauca), paper birch (Betula papyrifera), resin birch (Betula glandulosa), mountain alder (Alnus Viridis Crispa), thin leaf alder (Alnus incana tenuifolia), Scouler willow (Salix scouleriana), Bebb willow (Salix bebbiana), blue joint reedgrass (Calamagrostis Canadensis), Cladonia lichens, sedges, and mosses.[2]

This is an early seral species that colonizes freshly disturbed habitats, such as floodplains recently scoured by floodwaters. The seeds germinate immediately when they are deposited upon moist substrate, and the plant grows best on wet alluvium. It also commonly sprouts up in recently burned areas. It can grow on other types of disturbed habitats, such as roadsides and mine sites. It does not tolerate shade and will be shaded out as the habitat transitions to the forest when other trees begin to grow.[2]

This plant provides food for many animals, such as moose, deer, caribou, snowshoe hares, beavers, and small mammals and birds. It is especially palatable to moose, and it is nutritious. The plant also provides cover when it forms dense thickets. When it grows along waterways it provides overhangs for fish to hide under.[2]

Medicinal uses

This plant was used medicinally by the Eskimo for ailments such as skin sores and watery eyes.[4] Native Americans used parts of willows, including this species, for medicinal purposes, basket weaving, to make bows and arrows, and for building animal traps.[2] It is a species of diamond willow and can be used for woodworking.[2]
