May 18, 2011: Fuels Treatment Practices for Mixed Conifer Forests in the Southwest

Presenter: Alexander Evans (Forest Guild)

The webinar covered the guide’s definition of mixed conifer, past land use and management activities, fire regimes and historic conditions, and impact of altered fire regimes in mixed conifer forests of the southwest. Since Euro-American settlement, many mixed conifer forests have become more homogeneous and can therefore facilitate larger, higher-severity fires than those that occurred historically. Increasing heterogeneity in mixed conifer forests at the landscape scale to approximate historic conditions is important for achieving many management objectives, from fuel reduction to wildlife habitat. Dr. Evans also discussed effectiveness and impacts of different fuels treatment techniques such as prescribed fire, silvicultural treatments, and combinations of cutting and burning in mixed conifer forests. The Guide also draws on interviews with 75 managers and experts and the webinar included the synthesis of their insights into the impediments to management and ways of overcoming them. For example, smoke management and wildlife habitat protections are two common issues that can make treatments more complicated, though not impossible.
