BOTANICAL AND ECOLOGICAL CHARACTERISTICS

SPECIES: Salix fuscescens | Alaska Bog Willow
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].
