Pennsylvania Forestry Pamphlets Vol 2 Classic Reprint PDF Download

Excerpt from Pennsylvania Trees Trees are among the commonest and most conspicuous objects of nature. The numerous products derived from them are very use ful, often indispensable. In all ages trees and grasses have been the most important products of the soil. A dense and valuable tree growth covered originally almost the entire area of Pennsylvania. About 278 species of trees and shrubs are native to this State, of which number 125 are trees. The number of native representatives in the present forests is the same as in the original forest. While the number of representatives remains the same, yet one finds a marked difference in the degree of their abundance, and in their age, size, form, density, quality, value, and productivity. The original forest of the State was large, dense, and extremely productive. The present. Forests are small, Open, and very unproductive. Each gener ation of mankind has seen a smaller, more open, and less productive generation of forests. It is not a prophecy, but the statement of a fact, when we say that the source of our timber supply is becom ing an acute and vital question. Fast-vanishing forests and ever rising lumber prices are couriers of this fact. The Federal and some State Governments have already inaugurated policies to offset the present destructive tendency in our forests by starting constructive work. To date no state has made a greater advance in forestry than Pennsylvania. She has, however, just started on this useful mission. The men who are directing her forest. Policies are endeavoring to lay a substantial foundation upon which a stable superstructure may be reared. In order to accomplish this it is necessary to have the co-operation of the citizens of the State, especially the woodland owners and managers. Forestry needs the support of public senti ment. No substantial and permanent advance is insured until our citizens understand the fundamentals of forestry and can distin guish the important timber trees from the inferior weed trees. It is hoped that the sphere of usefulness of this bulletin, will not be limited to woodland owners and managers, but will extend to lay men, students, and botanists.
