Restoring health to ponderosa pine ecosystems while reducing threats of wildfire within the wildland-urban interface.

Management practices such as the suppression and exclusion of antiaircraft in the Southwestern bull pine pine ecosystem bear created problems by notably disturbing natural fire patterns and congenital plant health. These practices ontogenesis incidences of dwarf mistletoe infections and the risk of ruinous wildfires from hazardous snub accumulations. This is a serious problem for managers and residents of this ecosystem. takings and hazardous go off reduction of the Southwestern western yellow pine pine pine ecosystem should be the scarce methods used to reduce the panic of wildfires within the wildland-urban interface, as substantially as revitalize and support the health of this ecosystem. Before European-Ameri bottomland settlement, the ponderosa pine ecosystem consisted of striking diameter, widely spaced trees visited tell only by low-in cardinalsity, surface fires. The ponderosa pines have developed evolutionary traits such as: buddy-buddy bark, prolific s eed production, rapid seedling growth, persistent resinous needles that down to the ground and produce highly flammable litter, and longevity, all of which ar interpreted as adaptations to frequent, low-intensity, surface fires (Edmonds, 2000). The ponderosa pines are a fire-dependant species and require frequent low-intensity, surface fires each two to ten years for their continuous survival. Surface fires, usually ignited by lightning, enkindle remove ofttimes of the small, diseased, and decease vegetation (fuel).

Without frequent surface fires, these fuels build upon the forest chronicle to create a lad der for an ignited fire to make a crusade ! to the crown of the trees. Crown fires can produce catastrophic, heat-intensive fires that can sack away the forest floor, exposing the vulnerable mineral soil to erosion. When the mineral soil layer is damaged by a heat-intensive fire, ofttimes of the genetic materials and seeds can be lost from the resulting erosion and this can permanently alter the landscape. At this point after a heat-intensive fire, only bare soil remains and vegetation rehabilitation may be inhibited even...
