GenEst (Generalized Estimator) is a software tool for estimating the total
number of individuals arriving in an area during a specific time period when
their detection probability is unknown but estimable. Its development was
motivated by the need to accurately estimate the total number of bird and bat
fatalities occurring at wind and solar energy facilities, but it is applicable
in a variety of other contexts as well. Simple counts of carcasses are not an
accurate measure of the true number of fatalities because some carcasses are
inevitably missed in carcass searches. Furthermore, simple carcass counts do not
allow comparison among locations or years because carcasses may be detected at
different rates. This software uses data collected during carcass searches and
estimates of detection rates to accurately estimate the number of fatalities and
to provide a measure of precision associated with the estimate. These estimates
are fundamental to understanding acute and cumulative effects of renewable
energy development on wildlife populations. The software package is available
with a user-friendly graphic interface as well as a flexible and powerful
command-line implementation. GenEst includes tools for estimating searcher
efficiency, carcass persistence, and other detection probability parameters from
experimental field trials. Included in the software are example datasets for
analyses, standard R package help files, this user guide, and vignettes
detailing use at the command-line.
