SUMMIT COUNTY — With more than 3,000 miles of contiguous border with American Indian and Alaska Native-owned lands, the U.S. Forest Service wants to work more closely with tribal governments in the protection, respectful interpretation and appropriate access to Indian sacred sites.
U.S. Agriculture Secretary John Vilsack this month released a new report recommending that the agency should take steps to strengthen the partnerships between the agency, tribal governments, and American Indian and Alaska Native communities to help preserve America’s rich native traditions.
10-year research project show short-term warming boost, with subsequent degradation of ecosystem
By Bob Berwyn
SUMMIT COUNTY — Global warming can boost short-term plant growth, but over time, warming temperatures disrupt the nitrogen cycle and quickly lead to the deterioration of dry grassland ecosystems, according to a 10-year study done by Northern Arizona University scientists.
The researchers subjected four grassland ecosystems to simulated climate change during the decade-long study. Plants grew more the first year in the global warming treatment, but this effect progressively diminished over the next nine years, and finally disappeared.
Arizona research calculates wildfire carbon-balance impacts
By Summit Voice
SUMMIT COUNTY — Wildfires that have burned across almost 750,000 acres in Arizona are doing more than turning forests into charred stumps.
Researchers with Northern Arizona University say the fires, burning in unnaturally dense stands of ponderosa pine, are turning the forests from carbon sinks into net carbon producers — and, the fires have burned so hot that they aren’t finding many signs of regeneration.
