Increasing concern about climate change and the need to reduce carbon emissions has led to new policies and support mechanisms for developing alternative energy sources, including the development of biofuels for fossil fuel substitution. It may now be cost effective to consider harvesting brash from forest areas for this purpose.

The following downloadable guidelines ^(PDF-1078K) consider site selection for brash removal in upland conifer forests, with a focus on Sitka spruce stands.
