FOREST MANAGEMENT WORKSHOP MANUAL

MOUNTAIN SITE CLASSIFICATION

The following forestland classification system was developed as a simple method of determining forest site quality for use by the landowner. More technical systems of site classification are in use by foresters, district conservationists, and other resource managers.
Class I
Highly productive alluvial soils on flood plains of larger streams. Drainage variable. Subject to periodic flooding.
Class II
Highly productive well-drained alluvial-colluvial soils at the top of slopes or on narrow flood plains of mountain creeks.
Class III
Lower 1/3 of slope (higher on north-facing); in well-protected, moist cove sites, and on fertile benches situated on slope sites.
Class IV
Intermediate sites. Mid-slope positions on side or on open (wide) cove sites.
Class V
Marginal sites. Middle (flat or concave) portion of broad ridges. Upper 1/4 of slope on most exposed side slopes, but upper 1/3 of slope on steep south and southwest slopes, small finger ridges.
Class VI
The poorest sites. Narrow ridges or edge of broad ridges with more than 50% rocks and boulders or less than 3 inches of topsoil. These sites should not justify management for timber, but might have other values.
