Many people have been apprised of the value of early successional growth that results from commercial timber harvests. The following from Tom Wessels is another perspective that is in support of the ecosystem that an older forest provides:

There has been lots of research at both the Harvard Forest in Petersham, MA and the Hubbard Brook Research Station in NH regarding how older forests sequester carbon to a far greater degree than younger forests. I am sure there is also good research on the relationship between forest disturbance and increase in invasive exotics although I haven't delved into that. The key to countering there argument is that whenever we manage for certain species, like early successional wildlife, we also are managing in ways that are detrimental to other late successional species. Also what makes Pisgah so unique at a larger landscape-scale is exactly the large array of older forests it holds that is very different from the rest of Cheshire County. 

Tom Wessels is a terrestrial ecologist and a professor at Antioch University New England in the Department of Environmental Studies, where he founded a master's program in conservation biology. He is the author of three books and is an active environmentalist.

Also the attached document Preemptive and Salvage Harvesting of New England Forests: When Doing Nothing Is a Viable Alternative by David R. Foster and David A. Orwig suggests that the best approach to forest management is to do nothing.
