A few quotes from That I thought you might find interesting. This is only talking in relation to broadleaved woodland in the UK.

If ancient woodland is clear felled there is usually little or no loss of plant species, execpt for lichens and other bryophytes, provided it is replanted with native broadleaves (Forestry Comission, 1984)
|
Which makes me wonder whether the lichen and other bryophyte populations recover over time or are lost forever. At any rate it's alot better than the timber extraction which involves uprooting the stumps and buldozing ground.

Felling to increasestructural diversity in the course of normal management will aid conservation (Forestry Comission, 1984)
|
This doesn't directly mean that logging is beneficial but some of the timber may be used for such purposes without causing a problem, depending on the extraction techniques used.

Management often brings direct benefits to wildlife and it is these benefits that allow a compromise to be reached betwqeen conservation and timber growing (Steele and Peterken 1982)......managed woodlands usually contain a richer variety of habitats within a limited area and thus more species than unmanaged woods (Watkins, C., 1990)
|
There was another quote that gave the time period of unmanagement after which species diversity and conservation value declined but I can't find it at the moment.
