New analysis offers important forest health information
Colorful mushrooms that pop up in forests around the world are much more than decorative baubles. Much more than realized, fungi are key components of forest ecosystems, helping to regulate the carbon cycle and driving the nutrient exchange between soil and trees.
Alaska, Southwest could see early season forest fires
April precipitation may have helped dampen the potential for a severe wildfire season in parts of the Rocky Mountain region and in the adjacent Great Plains, according to a new outlook from the interagency Rocky Mountain Area Coordination Center.
The projections is based on various seasonal indicators including precipitation, snowpack average, temperatures, wind, plant and soil moisture, and the timing of green-up. These indices support a below average to near average fire season in 2016.
After taking a big-picture look at the water cycle, U.S. Forest Service researchers say global warming may decrease the amount of water produced by forests and grasslands across the country — even with increases in precipitation.

The Lower Austrian landscape encompasses everything from wild beech forests and deep river canyons to manicured fields — not to mention acres and acres of vineyard, but that’s another story! Austrians are still getting used to the concept of national parks. Thayatal was founded in 2002, so some local visitors still don’t quite understand why the park managers simply leave downed trees on the ground. It’s considered a waste by some, and the park features signs explaining how it’s a deliberate effort to recreate landscapes where natural processes are left to function without much interference. In this small country, nearly every acre of land is spoken for, most of it outside towns and cities dedicated to agriculture, but slowly, resource managers are making some headway in restoring natural ecosystems in a few areas, to the benefit of native species.
Global warming has killed half a billion trees across the U.S.
Scientists tracking massive forest die-offs say a new study may help forest managers learn how to predict which trees will succumb to global warming — and what the implications are for the global carbon balance.
“There are some common threads that we might be able to use to predict which species are going to be more vulnerable in the future,” said University of Utah biologist William Anderegg, explaining that recent tree-killing droughts in the western U.S. were marked more by elevated temperature than by a lack of rainfall.
“These widespread tree die-offs are a really early and visible sign of climate change already affecting our landscapes,” Anderegg said.
Long-term camping, littering and wildfire danger cited as reasons for proposal
A popular free camping zone between Keystone and Montezuma could be shut down by the U.S. Forest Service. According to the agency, the informal campsites have become a nuisance, with long-term campers damaging natural resources and littering the area with human waste and trash.
As proposed in April 2015, the the plan would have resulted in major real estate sprawl around the village of Tusayan, with up to 2,100 residential units and 3 million square feet of retail space along with hotels, a spa and conference center.
