There are only a few districts in the country which probably will never again support much tree growth.

Their denuded condition is due largely to the destruction of the neighboring mountain forests and to the activities of erosion.

Under ordinary conditions, natural reforestation will maintain a satisfactory tree growth on lands where a practical system of forest protection is practiced.
The complete removal of the forest is now accomplished only in fertile farming regions, where the agricultural value of the land is too high to permit it to remain longer in forest cover.
Even in the Mississippi Valley and the Great Lakes belts there are still large areas of forest land.

Most of the farms have woodlots which provide fuel, fencing, and some lumber.

For the most part, these farm woodlots are abused.
