This book was released on 1982 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arizona's natural ponderosa pine stands are characterized by open, mature groups and adjacent closed, dense thickets. The open structure of the mature groups permits a warm, dry environment, resulting in very low fuel moisture during much of the fire season and creating high ignition and fire spread potentials in the abundant fuels. The large woody fuel component of the adjacent closed groups contributes to a high crown fire potential in the low, dense sapling crowns. These findings suggest a need for fuel management activities where values-at-risk are high.
