Wolf Progress Reports 1999-2009

The Wisconsin Department of Natural Resources (WDNR), with its many partners and volunteers, has annually conducted surveys of gray wolves (Canis lupus) every year since winter 1979-1980. Techniques used to monitor wolf numbers include radio tracking of collared wolves, snow track surveys, and collection of reports of wolf observations.

The reports below summarize the DNR's wolf survey and summary findings through 2009. After 2009, all survey, progress, and research summary reports can be found in an annual, online Endangered Resources report: "Status of the Timber Wolf in Wisconsin Performance Report".

The Spring/Summer Survey Reports cover wolf surveys and management activity for April through September, including live-captures & radio-collaring, howl surveys, wolf mortalities, wolf movements, and any depredations on domestic animals.

The Fall Surveys and Annual Summary of Wolf Activities Reports cover wolf survey activity during fall and the summary of certain data for the calendar year including total wolf captures, total mortalities, and total wolf depredations. There is some overlap with this report and the Winter Report one. These reports are now included in Spring/Summer Report.

The Winter Surveys and Population Estimation Reports cover wolf survey activities including snow track surveys, pilot monitoring of collared wolves, volunteer tracking results, wolf movements, wolf mortalities, any depredations, and summary of the winter population count. This report also covers the background information of how we census wolves and the basis for our spring announcement of the new wolf population estimation for the state.
