An Evaluation of the Accuracy of Licensed Wolf Harvest Data and the Correlation with Population Trends in British Columbia Mowat G.

Abstract: 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.
