Tsuga mertensiana/Menziesia ferruginea
(mountain hemlock/rusty menziesia)
(TSUMER/MENFER; 19 sites)
IA1f. Closed needleleaf forest, mountain hemlock
A mountain hemlock / rusty menziezia stand on the 800' bench above Fourth of July Creek.
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.
