Analysis: Top Ten Carbon Storing National Forests in America PDF

National forests, national parks and other federally-owned forests in the Pacific Northwest and Southeast Alaska hold extraordinary amounts of carbon and therefore play an important role in defending against climate change. According to United States Forest Service data, the ten national forests in the United States that store the most carbon per forested acre are all located in western Oregon, western Washington and southeast Alaska. Moist late-successional forests west of the Cascade Range mountains are among the Earth's greatest carbon storing ecosystems.

Influences of Motorized Route Networks on Fisher (Martes pennanti) Habitat Quality in Sierra National Forest PDF

Roads and motorized trails can fragment landscapes and reduce the quality of adjacent habitat for a wide range of wildlife species. This report demonstrates an approach for assessing the influences of the extent and configuration of motorized route networks on habitat quality for fishers (Martes pennanti) in Sierra National Forest, in the central Sierra Nevada range of California.

Charcoal and Carbon Storage in Forest Soils of the Rocky Mountain West PDF

Charcoal produced during wildfire events represents an important form of long-term Carbon storage in forest ecosystems. Forest management practices, such as salvage logging or thinning without prescribed fire, may reduce soil charcoal content and, thus, long-term Carbon storage in mineral soils.   Conclusions  Charcoal represents an important component of the soil organic matter pool in temperate grasslands and forests. It contributes to the total water-holding capacity, ion exchange complex, and surface area of the soil environment.
