GTR-NE-319: Comprehensive Database of Diameter-based Biomass Regressions for North American Tree Species by Jennifer C. Jenkins, David C. Chojnacky, Linda S. Heath, & Richard A. Birdsey

A database consisting of 2,640 equations compiled from the literature for predicting the biomass of trees and tree components from diameter measurements of species found in North America. Bibliographic information, geographic locations, diameter limits, diameter and biomass units, equation forms, statistical errors, and coefficients are provided for each equation, along with examples of how to use the database. The CD-ROM included with this publication contains the complete database (Table 3) in spreadsheet format (Microsoft Excel 2002® with Windows XP®).

Below are links to Microsoft Excel Spreadsheets that are on the accompanying CD-ROM to this publication. PDF's are provided for users who do not use Microsoft Excel.

The full text report can be found under Treesearch
