    The Malheur National Forest is located in the Blue Mountains on Oregon's eastern side, the portion of the state that lies east of the Cascade Crest. In the mid s, researchers and land managers conceived a suite of experiments to explore the effects of prescribed fire on forest health. The studies were designed to coincide with prescribed burns conducted by the USDA Forest.   Post-fire conifer regeneration in ponderosa pine forests of the southern Rocky Mountains, USA Wildfires in the southern Rocky Mountain region have increased in size, frequency, and severity over the past three decades, but forest recovery following high severity wildfire events is .

    ponderosa pine type where decomposition is relatively slow, death of trees when their cambium or fine roots are damaged by smoldering fires, is of great concern. Numerous sources have observed that ponderosa pines with crowns scorched more than 50 percent usually become attractive to bark beetles. derosa pine and Douglas-fir comprise the majority of the overstory, with occasional lodgepole pine (Pinus contorta Douglas ex Louden) and western larch (Larix occidentalis Nutt) in mixture. Seedlings and saplings of shade-tolerant Douglas-fir are abundant in the understory, whereas simi-lar-sized ponderosa pines occur mostly in scattered thickets.

    Sampling of trees was conducted in the Side wildfire (4 May ), Bridger-Knoll wildfire (20 June ) and Dauber prescribed fire (9 September ) in northern Arizona ponderosa pine.

Cone maturation in ponderosa pine foliage scorched by wildfire. [Fort Collins, Colo.]: Dept. of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station, (OCoLC) Trees scorched to varying degrees were studied to determine the effects of a late fall wildfire on several cone and seed characteristics.

While cone size, seed soundness, and seed weight were markedly less in severly scorched trees, trees with crowns scorched as much as two-thirds produced highly viable seed. Trees scorched more than two-thirds yielded small amounts of seed of. Scorched.

Ponderosa pine is well suited to survive low-intensity surface fires primarily due to its bark characteristics. Ponderosa pine develops a protective outer corky bark ( cm) early in life whenCited by: Ponderosa pine ecosystems—Graham and Jain dominated by ponderosa pine, these or similar stages may develop in less than years but in other systems, such as Pacific coastal Douglas-fir (Psuedotsuga menziesii (Mirbel) Franco var.

Planting of ponderosa pine after wildfire may accelerate reforestation, but little is known about survival of plantings and the amount of post-fire natural regeneration.

We compared ponderosa pine regeneration between paired planted and unplanted plots at eight sites in Arizona and New Mexico that recently (–) burned by: EFFECT OF THINNING AND PRESCRIBED BURNING ON WILDFIRE SEVERITY IN PONDEROSA PINE FORESTS Jolie Pollet, Fire Ecologist Lakeview Bureau of Land Management HC 10 BoxLakeview, OR Phone: () E-mail: [email protected] Philip N.

It continued to burn for two days, torching approximately hectares (~ acres) of stands dominated by ponderosa pine. The wildfire burned into three BMERP. Ponderosa pine forests are especially susceptible to fires due to the extreme flammability of the foliage surrounding them on the forest floor (Cromack, ).

The Ponderosa pine itself, is considered to be fire resistant, and is only damaged when the fire “crowns” (burning at canopy height) and 60% or more of the tree is destroyed ().

Ponderosa pine delayed mortality, and bark beetle attacks and emergence were monitored on trees for 3 years following one prescribed fire in Idaho and one wildland fire in Montana. Resin flow volume (ml) was measured on fire-injured ponderosa pine 2 and 3.

The cambium at the base of the tree on the left in these pictures is scorched while the ponderosa pine on the right shows no obvious cambium damage and thus has a better chance of survival. Bud damage also is a factor in ponderosa pine survival after a wildfire.

The buds occur at the terminal ends of branches and are responsible for the. Ponderosa pine is not serotinous, thus requiring seed dispersal from adjacent areas to reforest stand-replacing wildfires; therefore seed availability has often been considered the limiting factor for regeneration following stand-replacing wildfire (Allen et al.,Bonnet et al., ).Cited by: The summer of was certainly a scorcher, with forest fires blazing across the Western United States.
