Dan - I couldn't find the pics I know you are taling about - they must be on my old Computer still.
Basically - they showed a browse line all the way around the field edge - Pictures of the same field 2 years after serious food plots - show Trees, shrubs, and forbs/grasses along the same field edges - right down to the ground.
Combined increased deer harvest & especially having food plots - AT THE RIGHT TIME OF YEAR - have helped to restore the field edges - as well as the understory in so many of our woods.
Woods that used to lookbarren on the forest floor - now have shrub, forb, and young tree growth - without cutting trees. In areas we cut trees out too - the growth is incredible.
Notice the green forb growth in this picture :
This is a 60 year old hemlock, cherrry, Ash, Maple & White Pine woods that was WIDE OPEN a couple years ago. In areas where trees fell or we cut - the woody growth is HUGE.
I'll try to get some good pictures this week when hunting.
