Landscape-scale management of forest wildlife populations in Wisconsin


August 2011 - June 2023


Conservation of species has shifted from single site efforts to landscape-scale approaches due to the scale at which forest management operates. And wildlife inventory and monitoring programs provide important data and tools to help assess how management may be influencing populations through space and time. However, while national forest managers can conduct monitoring activities on populations according to the Forest Plan, they often lack time and expertise to complete the quantitative analysis required to fully interpret the data. This project is a collaboration between the USGS Wisconsin Cooperative Wildlife Research Unit, researchers from the US Forest Service Northern Research Station, and managers from the Chequamegon-Nicolet National Forest. The project will evaluate several long-term wildlife monitoring programs to provide science-based information to support inventory and monitoring efforts that contribute to the management of ecosystems and activities on the national forest.
