IC2.-IC1. Open and closed mixed forest
A Sitka spruce - black cottonwood / common horsetail stand on a Resurrection River terrace.
Vegetation- Picea X lutzii (Lutz spruce) and Populus balsamifera ssp.
trichocarpa(black cottonwood) share overstory dominance in this type.
Equisetum arvense(common horsetail) is abundant and the indicator species
for this type. Calamagrostis canadensis (bluejoint reedgrass) is abundant
and shares dominance in the undergrowth. Fairly consistent tall shrub
components are Viburnum edule (highbush cranberry), Salix barclayi (Barclay
willow), and Rosa acicularis (prickly rose). Low and dwarf shrubs are sparse.
Remaining herbaceous species composition is quite variable, the most
common species including Sanguisorba stipulata (Sitka burnet), Epilobium
angustifolium(tall fireweed), Pyrola secunda (one-sided wintergreen), and
Physical setting- Lutz spruce-black cottonwood/common horsetail is a minor
type in the Kenai Mountains. It occurs on flood plains, flat lowlands, and
non-disturbed foot slopes. Sites sampled are on northerly aspects on slopes
up to 5 percent and at elevations from 400 to 1200 feet.
