Patch Retention

[image:] ¼ acre patch retention with vernal pool.Research Issue

Patch retention can be used to maintain certain components of biodiversity by leaving trees normally cut during a timber harvest.  Patch retention (patch retention, tree islands, leave patches, buffer strips, trail corridors) is applied during harvests, thinnings, regeneration cuts, and other silvicultural treatments to achieve desired ecological characteristics at different scales, ranging from sub-stand to watersheds and landscapes.  Landowners and managers need information about the tradeoffs between economic costs and ecological benefits to determine how to apply patch retention at levels consistent with their management goals.

Our Research

This study’s focus is on estimating the long-term opportunity/capital recovery costs and density of large trees (an indicator of ecological benefits) associated with alternative patch retention treatments in eastern oak forests.

Expected Outcomes

The results will provide information on the economic/ecological tradeoffs of implementing alternative patch retention treatments.
