What is Patch Cutting?

The patch cut system removes all the trees from a small area within a stand. In this study area, patch size varies from 0.5 hectares (the minimum considered necessary to provide the amount of light Douglas-fir needs to develop satisfactorily) to 2 hectares (the maximum area that is visually unobtrusive). After cutting, each patch is managed as a distinct, even-aged unit, and over time, the management area becomes a multi-aged mosaic of patches.
