We examined the British Columbia hunter survey data to see how accurately
the kill was estimated by the various methods of recording kills and to test how
well the kill data indexed changes in wolf abundance and distribution. All wolf
kill data are inaccurate to some unknown extent and sampling methods would
need to be changed to estimate the level of inaccuracy. Hunter and trapper kill
data can be used to index large changes in wolf abundance and distribution across
areas with large harvests. Use of harvest data to monitor population trend at finer
scales (Wildlife Management Unit or Population Management Unit) would
require improvements in harvest data collection. Hunter success and effort are
not good proxies to index trends in wolf abundance due to uncertainty in hunter
numbers and effort. We provide recommendations on how to improve the data.
