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.

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
