BOTANICAL AND ECOLOGICAL CHARACTERISTICS

SPECIES: Salix brachycarpa | Barren-Ground Willow
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].
