Tsuga mertensiana/Menziesia ferruginea

(mountain hemlock/rusty menziesia)

(TSUMER/MENFER; 19 sites)

Vegetation- Tsuga mertensiana (mountain hemlock) dominates the tree

layer. Picea X lutzii (Lutz spruce) is an important associated canopy species,

which is often codominant. Menziesia ferruginea (rusty menziesia) is

abundant in the tall shrub layer. Vaccinium vitis-idaea (lowbush cranberry) is

usually present or common, but rarely exceeds 5 percent cover. Other

shrubs are generally poorly represented or absent. Rubus pedatus (fiveleaf

bramble) is usually well represented.

Physical setting- Mountain hemlock/rusty menziesia is a common type in the

Kenai Mountains. It occurs on non-disturbed, dissected, and broken

mountain side slopes, non-disturbed foot slopes, and high relief hills. Sites

sampled are on all aspects, on slopes up to 75 percent, and at elevations

from 600 to 1900 feet.
