Silvicultural systems for the major forest types of the United States

The current trend toward the establishment and care of forests for a wide combination of uses requires flexibility in forest culture and a knowledge of the silvicultural choices available to the resource manager. This publication summarizes for each of 37 major forest types in the United States the silvicultural systems that appear biologically feasible on the basis of present knowledge. Supporting information is given on the occurrence of the 37 forest types, the cultural requirements of the component species, and the biological factors that control the choice of silvicultural options. The text is arranged in regional sections suitable for reprinting.Gerald W. Williams Collectio

State forests for public use

Progress in State forestry has been stimulated by Federal assistance since 1924 when Congress passed the Clarke-McNary Act authoriz­ing cooperation with the States in forest-fire control measures with a view to the protection of forest and water resources and to the continuous production of timber on lands chiefly suitable for the purpose. Under this cooperative program definite forest-land policies and action programs have been initiated. Protection of forests from fires and rehabilitation of devastated areas are needed to insure the social and economic stability of forest communities and workers. The possibilities of State forests as administrative centers in a broad conservation program on private lands have been demonstrated. The effectiveness of the field organ­izations is measured, however, largely by the available equipment and funds. Much remains to be done to improve present methods and to extend operations to cover areas as yet unprotected. The future livelihood of many communities is dependent upon the speed with which the forest-conservation program can be ex­panded. The one-third of our continental area classified as forest land must be protected and so managed that it will support its fair share of the population. State ownership and supervision of certain forest lands are now definitely recognized as means to this end. Additional millions of acres of tax-delinquent and devastated lands must eventually be brought under State or Federal custodian­ship. Consolidation of much of this land in additional State­owned forests will facilitate expansion of organized fire protection to all forest lands.Gerald W. Williams Collectio

Monitoring fluoride pollution in Flathead National Forest and Glacier National Park, 1972

During August 1972, 15 vegetation plots monitered for foliar fluoride concentrations in 1971 were resampled near the Anaconda aluminum plant at Columbia Falls, Montana. Statistical analysis of the data showed that essentially the same amount of fluoride was taken in by conifers, shrubs, and grasses in 1972 as in 1971. It is concluded that the area over which plants accumulated fluoride and resultant damage occurred remained unchanged from 1971 at 179,000 acres and 15,000 acres, respectively. Vegetation in Glacier National Park continued to show some fluoride injury and to accumulate abnormally high amounts of fluoride

Decay resistance of heated and unheated mesquite and Utah juniper post wood

The heartwood of mesquite (Prosopis juliflora var. velutina) and of Utah juniper (Juniperus utahensis) is generally considered to have outstanding decay resistance. Quantitative evidence of the juniper superiority appears in a study of old fence lines by Meagher. Nearly three fourths of the juniper posts averaging 3.6 inches in diameter were still serviceable after 50 years on woodland zones presenting moderate decay hazard. By way of comparison, less than half of the cypress posts of comparable size remained serviceable
