Effects of thinning, prescribed burning, and burning season on the physiological performance of ponderosa pine
Low elevation ponderosa pine (Pinus ponderosa Dougl. ex. Laws.) forests of the northern Rocky Mountains historically experienced frequent, low intensity fires that maintained open, uneven-aged stands. A century of fire suppression has led to denser ponderosa pine forests with higher competition for resources, higher tree stress, and greater risk of insect attack and stand destroying fire. Activ...

A century of fire exclusion has contributed to denser ponderosa pine forests with greater competition for resources, higher tree stress and greater risk of insect attack and stand-destroying fire.

متن کاملSearing the Rhizosphere: Belowground Impacts of Prescribed Fires
A century of fire suppression has resulted in dense fuel loads within the dry pine forests of eastern Oregon . To alleviate the risk of stand-replacing wildfire, forest managers are using prescribed fire and thinning treatments . Until recently, the impact of these fuel treatments on soil productivity has been largely unknown . Such information is essential for making sound management decisions...
متن کاملInfluence of humans and climate on the fire history of a ponderosa pine-mixed conifer forest in the southeastern Klamath Mountains, California
Fire history of a ponderosa pine-mixed conifer forest was investigated in the Whiskeytown National Recreation Area, southeastern Klamath Mountains, California. Fire return intervals were found to be frequent and similar to other comparable forests in California. Median fire interval for the six sample plots (1.4–1.7 ha) ranged from 2 to 4 years (mean range, 4.8–7.4 years). Most fires (93%) occu...
متن کاملManaging Ponderosa Pine Forests in Central Oregon: Who Will Speak for the Soil?
The soils of the central Oregon pumice plateau are relatively young and infertile, yet support an array of plant diversity and growth in the region’s pine forests. Whether these coarsetextured, pumice and ash soils are resilient to forest disturbance is not well understood. We present results from a long-term experiment that examined changes in soil quality in response to combinations of thinni...
