_Forest Protection Studies._ Studies in forest protection endeavor to find the best methods of protecting the National Forests from fire, grazing, disease, insects, wind, snow, hail, and animals. The most efficient protection of the National Forests from fire calls for an accurate, scientific knowledge of all the factors that enter into the problem. Comprehensive studies are undertaken to secure the basis for a more scientific method of distributing National Forest fire-protecting funds. The aim has been to find the degree of intensiveness in fire protection warranted by timber, forage, and watershed values, as modified by their susceptibility to damage by fire. Under the ideal system of allotting fire-protecting funds, the most valuable resources, which at the same time are most in danger of destruction by fire, should receive the largest amount of funds and therefore the greatest amount of protection. Less valuable resources, less susceptible to fire danger, should receive protection in proportion. Other classes of fire protection studies have to do with the various phases of fire prevention, fire detection, and fire control. Studies have also been carried on to determine the rapidity with which fire spreads in different forest types, and under a given set of climatic conditions. _Protection from Grazing Damage._ Studies of the effects of grazing upon the natural reproduction of forests are conducted with a view to devising a system of range control which would minimize such injury without requiring the total exclusion of the stock from the range. Studies have shown that serious damage occurs to seedlings under four feet in height during the dry season, on areas containing poor forage, or which have been overgrazed, or where there was little or no underbrush. It was found that sheep do twice as much damage as cattle. Some of the measures that have been adopted to lessen the injury to reproduction by sheep and cattle are: the revegetation of overgrazed areas, reductions in the amount of stock, provisions for the better distribution of stock by the regulation of watering places, and the exclusion of sheep from cut-over areas on which reproduction is deficient until the seedlings reach a sufficient height to be out of the reach of the animals.
