Hi, It is important to remember that an important part of most farms until recently was the woodlot. An 80 acre farm, for example, might have had 50 or 60 acres under cultivation or in pasture. The rest would have been woodlot. This was the source of fuel for heating and cooking as well as a source of timber for barn and fence construction. So, in an area with 1,000,000 acres of farms, not all of this was devoid of what we might call forest. Although there was extensive reforestation of some areas during the 30s, it was the stands of woodlot trees which provided the seeds for the return of the original mixed-species woods. Homer
