Abstract

Equations are presented for estimating the twig, foliage, and combined biomass for 58 plant species in interior Alaska. The equations can be used for estimating biomass from percentage of foliar cover of 10-centimeter layers in a vertical profile from 0 to 6 meters. Few differences were found in regressions of the same species between layers except when the ratio of foliar-to-twig biomass changed drastically between layers; for example, Rosa acicularis Lind[. Eighteen species were tested for regression differences between years. Thirteen showed no significant differences; five were different. Of these five, three were feather mosses for which live and dead biomass are easily confused when measured.
