Effects of Fire on Water Infiltration Rates in a Ponderosa Pine Stand

摘要: One of the more important ways in which water supplies can be maintained and, some cases increased substantially, is through proper management watersheds or land areas producing water. Attention being focused, particular, on supporting forest vegetation, specifically Arizona, ponderosa pine type. Watershed studies have shown that these forested areas, are normally limited to regions high rain and snow fall, best suited for intensive yield management. There are, however, practices may affect from a watershed. The importance as timber area has led protection wildfire. This resulted dense stand growth with destructive fire potential transpirational loss. In many South West, prescribed burning been used effectively reduce fuel hazards forest. For example, 400,000 acres Fort Apache Indian Reservation, all lie Salt River Watershed, burned periodically surface fuels raise crown levels. With periodic
