Statistics & Biometrics


Biometricians with WEST are internationally known for their common sense application of statistics to solve natural resource problems. They specialize in practical, state-of-the-art design and analysis of field and laboratory studies. WEST’s statisticians have written and published 9 books and over 250 manuscripts on the use of statistics in natural resource applications. To complement these books and articles, WEST offers short courses and workshops on a variety of statistical topics related to natural resource and wildlife applications.

WEST can provide state-of-the-art consulting on all aspects of studies designed to estimate size and geographic extent of a biological population. This expertise includes the use of capture-recapture, distance sampling and aerial survey methods. WEST has been actively involved in the development, review, and analysis of capture-recapture studies for the estimation of population parameters. WEST biometricians are internationally known experts in distance sampling and the development of models for analysis of capture-recapture. WEST developed and has conducted a population surveys for golden eagles across a ~2 million km2 area in the western US for the US Fish and Wildlife Service.

WEST’s major contribution in many studies is expert consultation on design and statistical analysis of field ecology studies. Emphasis is placed on development of study protocols and standard field procedures that result in statistical inferences, which are justified by the study design. WEST employees often contribute to field studies by directly participating in collection of field data.
