Results of Research to Develop Cost Effective Biomonitoring at Oil Shale Lease Tracts. Phase I. Fall Sampling Report

摘要

This report presents the results of censuses conducted during October 1981 to estimate the fall abundance of small mammals and avifauna on replicate plots in the vicinity of Federal Tract C-a (Rio Blanco Oil Shale Company). The objectives of the fall censuses were to evaluate alternative census techniques, test assumptions vital to the use of indices and abundance estimators, determine cost-functions associated with monitoring efforts, and estimate variance components needed to devise optimal monitoring designs. Analyses of the fall census data on small mammal abundance were performed.
