This is an interesting read about oaks being pushed out of where they once dominated in Monongahela National Forest in the Central Appalachians. The article is based on work from a local researcher and what he believes is the biggest culprit - deer. He encourages hunting. Story below:

There are plenty of mature oaks, but few baby oaks to take their place.
"We are marching down a road to losing the historical dominance of oak in the Eastern forests within the next 100 years, and once the process starts, it could be virtually impossible to stop," said Walter Carson, a plant ecologist at the University of Pittsburgh who is studying the phenomenon scientists call "failed oak regeneration."
Unless radical changes are made in forestry management practices, the economic and environmental consequences of this shift in tree species could devastate the American wilderness, Carson said.
Oaks provide a lucrative source of hardwood to West Virginia's timber industry, which brings in more than $3.2 billion annually to the state's economy, according to the state's Division of Forestry. The tree's familiar seed product -- acorns -- are a dietary staple for insects, migrating neotropical songbirds, small mammals, deer and black bear.
