Hey those are great ideas! All public land should be managed using those principles! But we have to make adjustments for private land most of which has been high-graded. Sometimes we have to take out up to 1/2 the volume on severely high-graded woodlots because species diversity has already been diminished on these lots as well as timber quality. On these lots we need to work to restore species diversity so sometimes that requires cutting a bit heavier than the recommended 20 - 35%. I agree more dead wood should be left in the woods but landowners don't like it so we have to compromise. Connectivity can mean establishing "greenways" or in forestry it could mean don't fragment the forest with clearcuts or patch cuts.
Mike and from Jim Drescher who suggests 5 management principles: 1.maximize canopy height 2. keep canopy closure ... to the natural range in the mature Acadian Forest. The natural canopy closure , 65%-80% closed, has evolved in synchronization with the existing biodiversity. 3. Maintain volumes and distribution of dead wood very close to those found in the old-growth reference points 4. don't do anything to reduce species diversity 5.maintain connectivity, or enhance it where it has been diminished --~--~---------~--~----~------------~-------~--~----~ Eastern Native Tree Society http://www.nativetreesociety.org Send email to [email protected] Visit this group at http://groups.google.com/group/entstrees?hl=en To unsubscribe send email to [email protected] -~----------~----~----~----~------~----~------~--~---
