Chojnacky is a Research Forester in the Bark +Beetle Disturbance Ecology Research Work Unit at Rocky +Mountain Research Station in Logan, UT.

His research interests include forest measurements, sampling, wildlife habitat assessment, bark +beetle hazard rating, and dryland forests. +Research Summary +The Forest Inventory and Analysis (FIA) group within +the Forest Service, U.S. Department of Agriculture, conducts forest resource inventories nationwide with various +sample designs. This paper documents the use of double +sampling for FIA inventories in the Interior West. Results +show that 18 equations describe the entire inventory +summarization process for estimating population totals +and means, and respective variances. Most equations +are for standard use of double sampling, but equations +are also given for a ratio method and a special method +for data defined by county and land ownership. Inventory +data from 800,000 ha of forest land in southern Idaho are +used to illustrate application of several equations \ No newline at end of file -- 2.18.1
