ABBREVIATION : SALBRA SYNONYMS : NO-ENTRY SCS PLANT CODE : SABR SABRN COMMON NAMES : barren-ground willow TAXONOMY : The currently accepted scientific name for barren-ground willow is Salix brachycarpa Nutt [19]. There are two recognized varieties based on slight morphological and ecological differences [15,19,22]: var. brachycarpa Nutt. (typical variety) var. niphoclada (Rydb.) Argus (artic variety) LIFE FORM : Shrub FEDERAL LEGAL STATUS : No special status OTHER STATUS : NO-ENTRY


DISTRIBUTION AND OCCURRENCE

SPECIES: Salix brachycarpa
GENERAL DISTRIBUTION : Barren-ground willow grows throughout Alaska except for the Aleutian Islands and along the southeastern coast. In northern Canada it grows from the Yukon Territory to adjacent British Columbia and east to the Hudson Bay. In the contiguous United States barren-ground willow grows from the Canadian border southward in the cordilleras to Utah and Colorado [3,7,15,19].

In northwestern Colorado, it is a codominant along rivers and streams along with diamondleaf willow (Salix planifolia), marsh marigold (Caltha leptosepala), and water sedge (Carex aquatilis) [3]. Other riparian community associates include Alaska willow (S. alaxensis), littletree willow (S. arbusculoides), grayleaf willow (S. glauca), and alders (Alnus spp.) [4,18].

MANAGEMENT CONSIDERATIONS

SPECIES: Salix brachycarpa
IMPORTANCE TO LIVESTOCK AND WILDLIFE : Barren-ground willow is an important forage for moose in the floodplains of interior Alaska and has been planted for moose habitat restoration on the North Slope of Alaska [8,26]. Willows (Salix spp.) are generally a preferred food and building material for beaver [2]. Willow shoots, catkins, and buds are eaten by numerous small mammals and birds [5,12]. PALATABILITY : NO-ENTRY NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : Willow stems are commonly planted for restoration of wildlife habitat, streambank protection, and the reclamation of sites disturbed by mining and construction [20]. Barren-ground willow is apparently well suited for these purposes. Barren-ground willow is also planted for windbreaks [27]. OTHER USES AND VALUES : All willows produce salacin which is closely related chemically to aspirin. Native American used various preparations from willows to treat toothache, bee stings, stomachache, and diarrhea [14,17]. Native Americans also used flexible willow stems for making baskets, bows, arrows, and fish and muskrat traps [14]. OTHER MANAGEMENT CONSIDERATIONS : NO-ENTRY

BOTANICAL AND ECOLOGICAL CHARACTERISTICS

SPECIES: Salix brachycarpa
GENERAL BOTANICAL CHARACTERISTICS : Barren-ground willow is a much-branched, low-growing, and often prostrate shrub typically between 1 and 3 feet (0.3-0.9 m) tall. Male and female flowers occur on separate plants in 0.7- to 2-inch-long (1.5-5 cm) catkins that persist throughout the summer and often through the following winter. The fruit is a two-valved capsule [3,6,19,28]. RAUNKIAER LIFE FORM : Phanerophyte REGENERATION PROCESSES : Like all willows, barren-ground willow's primary mode of reproduction is sexual. It produces an abundance of lightweight seed and begins seed production at an early age (between 2 and 10 years) [12]. Willow seed has an extremely short period of viability. Under natural conditions, most seeds remain viable for only a few days. Seeds usually germinate within 12 to 24 hours of landing on a suitable seedbed. At maturity, the capsular fruits split open to release the minute downy seeds that are dispersed by either wind or water [12,19]. Vegetative reproduction: Willows are prolific sprouters. Barren-ground willow sprouts from the root crown if aboveground stems are broken or destroyed by cutting or fire [12]. SITE CHARACTERISTICS : Barren-ground willow occurs on a wide variety of sites including open woodlands, bogs, muskegs, meadows, streambanks, alpine slopes, swamp margins, and moraines. It also occurs on serpentine barrens, salt marshes, alkaline meadows, and salt flats [11,28]. SUCCESSIONAL STATUS : Obligate Initial Community Species Barren-ground willow is an early seral species. It is one of the first species to become established on exposed silt and gravel bars and the inside of river meanders [1,18]. SEASONAL DEVELOPMENT : Barren-ground willow flowers in June and July, and the seed is dispersed in July and August [28].

FIRE ECOLOGY

SPECIES: Salix brachycarpa
FIRE ECOLOGY OR ADAPTATIONS : Information on barren-ground willow's ability to sprout after fire is lacking. Like most willows it probably sprouts prolifically after fire. Barren-ground willow's wind-dispersed seed are probably important in colonizing recently burned sites [12]. POSTFIRE REGENERATION STRATEGY : Small shrub, adventitious-bud root crown Initial-offsite colonizer (off-site, initial community)

FIRE EFFECTS

SPECIES: Salix brachycarpa
IMMEDIATE FIRE EFFECT ON PLANT : Low- to moderate-severity fires generally top-kill willows. Severe fire can kill willows by completely removing soil organic layers and charring the roots [29]. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Like most willows barren-ground willow will probably sprout vigorously after fire [3,12]. Information regarding postfire establishment for barren-ground willow is lacking. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : NO-ENTRY
