Stands are dominated by ponderosa pine, and are divided into moist, mesic, and dry stand types with decreasing elevation and moisture availability. A historical fire regime of frequent, low-severity surface fires is widely documented, but there is growing evidence of historical mixed-severity and high-severity fires, especially for steep slopes Author: John L.

Cited by: ” Prior to European settlement, northern Arizona’s Ponderosa pine stands had 20 to 40 trees per acre. Today, many areas of northern Arizona have to 1, trees per acre. This is a much greater density than can be supported under our climatic conditions.
The Warner Mountains of northeastern California on the Modoc National Forest experienced a high incidence of tree mortality () that was associated with drought and bark beetle (Coleoptera: Curculionidae, Scolytinae) attack.

Probability of ponderosa pine infestation by mountain pine beetle in the Colorado Front Range. Invasive species are a rapidly expanding threat to wildland ecosystems throughout the Western United States. Invasive species are defined as those that are nonnative to the invaded ecosystem and whose introduction is likely to result in economic or environmental harm, or reduce ecosystem integrity.
We have also included native outbreaks of plants, pathogens, and insects within their. Mountain pine beetle-caused mortality over eight years in two pine hosts in mixed-conifer stands of the southern Rocky Mountains. Forest Ecology and Management. Williams, Mary I.; Dumroese, R.

What is a pest pp, 3() 1. What is a Pest. A pest can be defined as a plant, animal, insect, or pathogen, acting singly or in combination, often aggravated by environmental stressors, which by its presence, abundance, or activity interferes with accomplishment of resource management goals and objectives.

Abstract. Climate-driven tree mortality has increased globally in response to warmer temperature and more severe drought. To examine how tree mortality in semi-arid biomes impacts surface water balance, we experimentally manipulated a piñon-juniper (PJ) woodland by girdling all adult piñon trees in a 4 ha area, decreasing piñon basal area by ~65%.Cited by: 6.

In western North America, efforts have concentrated on single tree or small scale stand protection, primarily from mountain pine beetle, Dendroctonus ponderosae Hopkins, infestations. Results have been favorable but inconsistent.
Lodgepole pine stands harbour a major commercial significance in British Columbia. The lodgepole pine forests not only make up half of the British Columbia Interior annual harvest, but are also highly utilized and acceptable for lumber and pulp production.
Unfortunately, mature lodgepole pine stands have been surmounted by outbreaks of mountain pine beetle, which is. Mountain pine beetle-caused tree mortality in uneven-aged ponderosa pine stands in the Black Hills of South Dakota and Wyoming was found to be positively correlated with basal area and ponderosa pine stand density index, which is similar to previous findings in even-aged stands (Schmid and Mata ).
