IIB1b. Closed tall scrub, alder


Vegetation- Alnus crispa ssp. sinuata (Sitka alder) is abundant and

dominates this tall shrub type. Echinopanax horridum (devilís club) is a

Physical setting- Sitka alder-devilís club is a major tall shrub type in the

Portage, Placer, and Twentymile wetland area and in the Kenai Mountains. In

the wetland area this type is usually found on flood plains. Sites sampled in

the wetland area are mostly on northerly aspects with slopes to 45 percent

(but most sites are level) and elevations to 400 feet. In the Kenai

Mountains this type occurs on dissected and non-disturbed side slopes.

Sites sampled in the Kenai Mountains are on all aspects, on slopes up to 80

percent, and at elevations to 1950 feet.
