ABBREVIATION : SALFUS SYNONYMS : Salix arbutifolia Pall. SCS PLANT CODE : SAFU COMMON NAMES : Alaska bog willow TAXONOMY : The currently accepted scientific name for Alaska bog willow is Salix fuscescens Anderss. [9]. There are no recognized subspecies, varieties, or forms. LIFE FORM : Shrub FEDERAL LEGAL STATUS : No special status OTHER STATUS : NO-ENTRY


SPECIES: Salix fuscescens
GENERAL DISTRIBUTION : Alaska bog willow occurs throughout most of the Alaskan boreal forest except in the Aleutian Islands and the along the southeastern coast of Alaska. Outside of Alaska, its range extends from the Yukon Territory to the Hudson Bay [2,12,18] ECOSYSTEMS : FRES11 Spruce - fir STATES : AK MB NT YT BLM PHYSIOGRAPHIC REGIONS : NO-ENTRY KUCHLER PLANT ASSOCIATIONS : K094 Conifer bog SAF COVER TYPES : 12 Black spruce SRM (RANGELAND) COVER TYPES : NO-ENTRY HABITAT TYPES AND PLANT COMMUNITIES : NO-ENTRY


SPECIES: Salix fuscescens
IMPORTANCE TO LIVESTOCK AND WILDLIFE : Willows (Salix spp.) are generally preferred food and building materials for beaver [1]. Willow shoots, catkins, leaves, and buds are eaten by numerous small mammals and birds [6]. Willows are a staple year-round food for moose. Moose browse on twigs in winter and consume leaves and new shoots in summer [6]. PALATABILITY : NO-ENTRY NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : Willow stem cuttings are commonly planted for restoration of wildlife habitat, streambank protection, and the reclamation of sites disturbed by mining and construction [10,13]. Alaska bog willow is apparently well adapted for these purposes [11,14]. OTHER USES AND VALUES : All willows produce salacin, which is closely related to aspirin. Native Americans used various preparations of willows to treat toothaches, bee stings, stomach aches, and diarrhea; they used the stems for making baskets, bows, arrows, and fish and muskrat traps [8,12]. OTHER MANAGEMENT CONSIDERATIONS : NO-ENTRY


SPECIES: Salix fuscescens
GENERAL BOTANICAL CHARACTERISTICS : Alaska bog willow is a native, low-growing, much-branched, trailing deciduous shrub 4 to 12 inches (10-30 cm) tall [18]. Male and female flowers occur on separate plants in 0.75 to 1.5 inch (1.9-3.8 cm) long catkins. The fruit is a two-valved capsule [2,13,18]. RAUNKIAER LIFE FORM : Phanerophyte REGENERATION PROCESSES : Like all willows, Alaska bog willow's primary mode of reproduction is sexual. It produces an abundance of small, lightweight seed. It probably begins seed production at an early age (between 2 to 10 years). At maturity the capsular fruits split open to release the minute downy seeds that are dispersed by either wind or water [6,13]. Vegetative reproduction: Willows are prolific sprouters. Alaska bog willow sprouts from from the root crown if aboveground stems are broken or destroyed by cutting or fire [6]. SITE CHARACTERISTICS : Alaska bog willow commonly occurs in wet tundra, small bogs, swamps, riverbanks, and in open black spruce (Picea mariana) muskegs throughout most of the Alaskan boreal forest [2,18]. Frequent associates include alder (Alder spp.), bog birch (Betula glandulosa), balsam popular (Populus balsamifera), and numerous willows (Salix spp.) [3,7,13]. SUCCESSIONAL STATUS : Obligate Initial Community Species Alaska bog willow is an early seral species. Like other willows it probably becomes abundant after disturbances that open the canopy and expose the mineral soil. It occurs in the early seral stages following fire in black spruce stands [18]. SEASONAL DEVELOPMENT : Alaska bog willow flowers in June; the fruits ripen in July [18].


SPECIES: Salix fuscescens
FIRE ECOLOGY OR ADAPTATIONS : Information on Alaska bog willows's ability to sprout following fire is lacking. It probably sprouts prolifically immediately after fire. Like most willows, Alaska bog willow's wind-dispersed seed are probably important in colonizing recently burned sites [6]. FIRE REGIMES : Find fire regime information for the plant communities in which this species may occur by entering the species name in the FEIS home page under "Find Fire Regimes". POSTFIRE REGENERATION STRATEGY : Small shrub, adventitious-bud root crown Initial-offsite colonizer (off-site, initial community)


SPECIES: Salix fuscescens
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 [19]. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Like most willows, Alaska bog willow probably sprouts vigorously after fire [2,6]. Information regarding postfire establishment for Alaska bog willow is lacking. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : NO-ENTRY
