Back in June 2009, someone named Tom posted a great question about applying the Dauerwald concept in Minnesota. In a nutshell, the Dauerwald approach involves intensive management designed to maintain a high diversity of tree species and ages. This approach can be attractive to those interested in active management but less comfortable with more extensive harvests such as clearcuts or shelterwood treatments.
This month we feature a two-part video response to Tom’s question and the ensuing discussion from Tony D’Amato, silviculturist at the University of Minnesota’s Department of Forest Resources. Tony’s first video addresses the concept of natural disturbance-based silviculture. His second video addresses a somewhat related concept, of active management to restore late-successional structure. Tony discusses how ecological forestry can complement other approaches like production forestry and multiple use sustained yield forestry on the landscape.

How does (or doesn’t) ecological forestry fit into your woodland plans? Why or why not? Leave a comment below or add to the initial discussion begun by Tom.
