Publisher's Synopsis
Excerpt from The Forest Resources of New Hampshire
Through the mcsweeney-mcnary Act of 1928, Congress authorized the Secretary of Agriculture to conduct a comprehensive survey of the forest resources of the United States. This work was assigned to the Forest Service. The purposes of this forest survey are (1) to make a field inventory of the present supply of standing timber; (2) to ascertain its current rate of growth, (3) to determine how much it is being reduced through industrial and domestic uses, fire, and other causes, (4) to estimate the present consumption and the probable future trends in requirements for forest products, and (5) to interpret and cor relate these findings so that they may be useful in formulating private and public forest policies.
Results of this first comprehensive survey of the forest resources of New Hampshire are reported here. However, other estimates of the State 3 forest inventory have been made in the past, the most recent being the Reappraisal of 1945, which was made by the Forest Service in cooperation with the American Forestry Associa ion These previous estimates were based largely on general knowledge and on the judgment of informed persons; the present survey is based on a scientifically designed procedure using aerial photographs and ground plots. Furthermore, some specifications used in this report are different from those used in previous studies. For these reasons changes in forest conditions in New Hampshire cannot be determined by comparing this report with previ ous estimates. Valid comparisons of changing forest conditions in New Hampshire will be possible when the same area is resurveyed in the future.
