That may be true but I can't say for sure. Maybe in areas where they do salvage cuts, they might exceed the 1%/yr. rate.
The Bureau of Forestry currently maintains 150 acres of deer exclosures in High Tensile
Electric and Woven Wire fences. Over the past 10 years, 800 acres of forestland have been
harvested for timber, forest age class structure, and wildlife management goals. We have
plans to conduct 400 acres of additional timber harvest in this area over the next 5 years.
Currently, 35 % of timber harvests in this area must be fenced to ensure forest regeneration
and sustainability.
But the thing that I think is significant is that because of damage done by insects and disease the canopy is more open allowing more regeneration in areas that have not been cut. That would indicate if DCNR did more work to open the canopy in the forests surrounding a planned cut, they wouldn't have to do as much fencing.
