Title
Pacific Northwest Plant Biomass Component Equation Library
Abstract
This database contains a collection of regression equations to predict various biomass components for many plants of the Pacific Northwest based on common parameters such as diameter, height, and cover. Documentation, including sources of raw data and source publications, is provided for each equation.
