Forest fragmentation alters global carbon cycle

Careful measurements show how roads and other disturbances affect moisture and the ability of fungi and bacteria to break down dead wood

FRISCO —Logging roads, clearcuts and other disturbances that fragment forests can slow the decay of dead wood and significantly alter the cycling of carbon and nutrients in woodland ecosystems, according to a new study.

Scientists with Earthwatch and the University of Exeter (UK) took a hard look at global forest fragmentation, starting the well-known fact that the edge effect influences temperature, moisture and other elements of forest microclimates. But the effect on the carbon cycle is less understood, so the researchers used on-the-ground experiments combined with modeling to try and fill the gaps. Continue reading

More than 20 people, from California to Pennsylvania, responded with donation. We know there are more Summit Voice readers and subscribers ready to step up, and this could be the best time, with a generous sponsor willing to match every dollar you donate. Continue reading

Wildfire activity well below average for year to-date

The far West and northern Great Basin are especially prone to wildfires this summer.

Potential for big fires still a concern in California

By Bob Berwyn

FRISCO — For the first time in 10 years, the acreage burned by wildfires was less than 1 million acres as of the beginning of July. With extreme drought and high fire danger in parts of the far West, that could change quickly, but for now, both the number of fires and the acreage affected is well below average for the season, according to the National Interagency Fire Center.

To-date, 26,684 fires have burned across about 909,000 acres, less than half he average 2.5 million acres for this time of year. By comparison, wildfires had already burned across more than 1.7 million acres last year at this time. In 2011 that number was at 4.8 million acres. Continue reading

Colorado: Forest Service comment letter shows breadth and depth of impacts from Denver Water’s diversion plan

Current plan underestimates impacts to water and wildlife

By Bob Berwyn

FRISCO — As currently spelled out, Denver Water’s plan to divert more water from the headwaters of the Colorado River will result in unacceptable impacts to wildlife and other resources on publicly owned national forest lands, the U.S. Forest Service wrote in a June 9 comment letter to the U.S. Army Corps of Engineers.

The Forest Service also wrote that the creation of a pool of environmental water in an expanded Gross Reservoir doesn’t compensate for the loss of two acres of wetlands and 1.5 miles of stream habitat that will be lost as a result of the expansion. Continue reading

Colorado boosts funding for early wildfire response

From flood to flames: Western Colorado under Red Flag warning; wildfire danger highest in far west and Southwest

FRISCO — It doesn’t take long to go from floods to fire in Colorado. Even with mountain streams still running high with runoff, weather experts say the fire danger is on the rise as June turns warm and windy. About a third of the state (mostly western Colorado) is under a Red Flag warning going into the weekend, with the National Weather Service warning that warm temps, low humidity and gusty winds will combine to raise the risk of wildfires.

Overall, the fire season outlook for Colorado is not as critical as the past few years, according to the National Interagency Fire Center, which is emphasizing the current fire danger in the far west and the Southwest, including big parts of Arizona and southwestern New Mexico. Continue reading

Numerous Colorado projects delayed as feds juggle budgets in era of monster wildfires

By Bob Berwyn

FRISCO — U.S. Forest Service officials said they’ve had to defer reviews of ski area projects, delay trail improvements and forest restoration work because of the high cost of fighting wildfires. This year, the agency projects a $470 million gap that ripples through the entire Forest Service budget.

More than a dozen important projects in Colorado were on the hit list, according to a  new report released this week by the Department of Agriculture. Some of the projects were canceled altogether because their funding has been diverted to fighting wildfires.   Continue reading

Climate: Forest growing season expands

Detailed Harvard research tracks changes in eastern forests

Staff Report

FRISCO — Forests in the eastern U.S. are greening up earlier than ever and staying green longer at the end of the growing season, Harvard scientists conclude in a new study.

Thanks to the extended growing season, the trees are storing more carbon dioxide, but there’s no guarantee that beneficial side effect will persist into the future, the researchers said, explaining that changing precipitation patterns could disrupt forests in other ways. Continue reading

Is global warming the knockout punch?

Staff Report

FRISCO — After watching Amazon forests change for decades, a team of researchers say the region is under the gun from multiple threats that threaten to deliver a knockout punch.

The 35-year study focused on how diverse communities of trees and vines respond when the Amazonian rainforest is fragmented by cattle ranching. Continue reading

Is out-of-state firewood a threat to Colorado trees?

State Forest Service warns against transporting firewood

Staff Report

FRISCO — It may be a little like the Dutch boy putting his finger in the leaky dike, but Colorado Forest Service officials are warning that transporting firewood from place to place may increase the spread of invasive tree-killing bugs.

Moving firewood even short distances increases the risk to Colorado’s native forests and urban trees. With the 2013 detection of the highly destructive emerald ash borer in the City of Boulder, and ongoing bark beetle epidemics in the state’s mountain forests, the Colorado State Forest Service wants to be sure people are aware of the risks associated with moving firewood.
