Environment: New mapping project traces global forest degradation

Spruce beetle populations are surging in the southern Rocky Mountains.

Conservation advocates say more protection needed to protect critical ecosystem services

Staff Report

FRISCO — Forest degradation continues unchecked in many parts of the world and especially in the northern hemisphere boreal forest belt in Canada, Russia and Alaska, conservation advocates said this week, unveiling new maps showing forest impacts across more than 100 million hectares — an are three times the size of Germany.

Just since 2000, about 8 percent of the world’s remaining intact forest landscapes have been subject to some type of degradation from human activities, including logging and energy development.

The Greenpeace GIS Laboratory, the University of Maryland and Transparent World, in collaboration with the World Resources Institute and WWF-Russia, used satellite technology to determine the location and extent of the world’s last remaining large undisturbed forests, important harbors for biodiversity that are still unaffected by logging and infrastructure such as roads, mining and oil or gas development.

Are New Mexico forests holding steady in the face of climate change, drought and wildfires?

New inventory assesses state’s woodland resources

STAFF REPORT

FRISCO — Mortality is increasing and growth is slowing down in New Mexico’s forest lands, according to a new forest inventory released in late August. The only species showing overall growth are ponderosa and piñon pines, as well as junipers, as insects, wildfires drought and disease take an increasing toll on the state’s woodlands.

Forests grow on about 25 million acres in New Mexico, with 44 percent on private lands and 31 percent on national forest lands. About 40 percent (10.8 million acres) of the forests are piñon-juniper woodlands, by far the state’s most extensive forest type. Gambel oak is the most abundant tree species by number of trees, and ponderosa pine is the most abundant by volume or biomass. Overall, researchers estimate there are more than 6 billion live trees growing in the state.

The inventory documented the drought-induced piñon pine die-off in the early 2000s, estimating that about 8 percent the species died, but noted that the mortality rate has tapered off.New Mexico’s aspen forests, covering about 380,000 acres, held steady in the past decade. Continue reading

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

Crowdfunding project includes matching funds

By Bob Berwyn

FRISCO — The generous response to last month’s call for grassroots donations has encouraged us to tap into a great fundraising opportunity with Beacon, a cool new journalism incubator and crowdfunding platform.

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
