Picea X lutzii-Populus balsamifera ssp. trichocarpa/Equisetum arvense

(Lutz spruce-black cottonwood/common horsetail)

(PICLUT-POPBALT/EQUARV; 5 sites)

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

Cornus canadensis (bunchberry).

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.
