Brett Wolk at Colorado Forest Restoration Institute describes that “in the fall of 2014, the Front Range Roundtable identified the need for best management practice guidelines on chipping and mastication on the Colorado Front Range. These guidelines were collaboratively developed by the Colorado Forest Restoration Institute and the Southern Rockies Fire Science Network for and with the Front Range Roundtable. A wide range of professionals contributed their expertise and perspectives to this project. The purpose of this document is to clarify the benefits and limitations of mulching, and to inform planning of mulching projects in forests and woodlands along the Colorado Front Range.”
