Title: Site index, height growth, normal yields and stocking levels for larch in Oregon and Washington.

Author: Cochran, P.H.;

Date: 1985

Source: Res. Pap. PNW-RP-424. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 24 p

Publication Series: Research Note (RN)

Description: Even-aged stands of larch in Oregon and Washington have cubic volume yields similar to yields from larch in Idaho and Montana. Site index values derived from the heights of the single tallest tree on 1/5-acre plots at an age at breast height of 50 years range from 50 to 110 feet. These values have the same index to productivity as the site index values of 30 to 90 feet based on average height of dominant and codominant trees at a total age of 50 years. Maintaining basal area levels between 45 and 75 percent of normal once trees reach commercial size is recommended.

Keywords: site index, increment (height), yield (forest), stocking level, larch
