Abstract
More than three million acres of woodland have been cleared since 1952 and converted to other uses - cropland and pasture, homesites, highways, airports, and industrial sites. And yet the area of farmland that has reverted to forest in recent years has exceeded the area cleared for pasture and crops in the Northern States. Land cleared for agricultural uses is usually second-growth woodland, while that cleared for residential uses is more apt to be good forest land.
