摘要

This interagency technical reference provides the basis for consistent, uniform, and standard vegetation attribute sampling that is economical, repeatable, statistically reliable, and technically adequate. While not all inclusive, this reference does include the primary vegetation sampling methods used across the West (frequency methods, dry weight rank method, Daubenmire, line intercept, density method, comparative yield, etc.).
