Crushing, also commonly known as trampling, is a method of site preparation whereby heavy machinery is used to knock down an rum over dead and unmerchantable trees, and unwanted vegetation. This treatment is usually followed by a prescribed burn or a slash windrowing operation to eliminate as much of the downed material as possible prior to planting. This method of site preparation has been practiced in the past in Ontario for the treatment of difficult sites. Despite its limited use and the operational concerns involved, there is potential for this type of treatment on sites having heavy residuals and brush. This report gives details and results obtained during field studies undertaken by FERIC on two Winter crushing operations in Ontario.
