Abstract

Basinwide visual estimation techniques (BVET) are statistically reliable and cost effective for estimating habitat and fish populations across entire watersheds. Survey teams visit habitats in every reach of the study area to record visual observations. At preselected intervals, teams also record actual measurements. These observations and measurements are used to compute calibration ratios that correct for observer bias. This publication introduces modifications of the original BVET protocols and provides examples and practical instructions for use by resource managers.
