Conservation advocates say more protection needed to protect critical ecosystem services
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.

New inventory assesses state’s woodland resources
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

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

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

Can we log our way to forest health?
Science sometimes missing from forest management policies
By Bob Berwyn
FRISCO — While politicians and policy makers continue to conflate a number of complex forest health and wildfire issues, a new study suggests there’s little evidence supporting the idea that logging helps to control or contain the spread of tree-killing pine beetles.
Nobody disputes the need to clear trees, brush and other fuels from around homes in fire-prone forest areas, but some lawmakers who should know better have been pushing for more logging under the guise of restoring forest health and as an antidote to insect infestations.
The idea that speedy approval of logging projects could help restore forest health was also used as a basis for short-cutting environmental reviews for logging projects, possibly resulting in negative long-term environmental impacts in forests.
But forest researchers in California and Montana said there isn’t much monitoring to assess the effectiveness of logging, and that failures often aren’t reported, probably because they don’t fit the popular narrative. Continue reading

Budget woes still hindering forest restoration efforts

By Bob Berwyn
FRISCO — The Colorado high country may be buried in snow right now, but lawmakers and fire experts are already brainstorming about the upcoming wildfire season.
As part of that process, Sen. Mark Udall (D-Colo.) met with local officials in Summit County recently to get feedback on recent successes and remaining challenges in forest management and wildfire mitigation policies and actions.
“It’s not a question of if we’re going to have more megafires, but when,” Udall said, without ever mentioning global warming as a key factor in the wildfire equation. Continue reading

Smooth-barked trees better able to repel insects
By Summit Voice
FRISCO — Lodgepole and ponderosa pines with smoother bark may be better at repelling tree-killing bugs, according to Boulder-based researchers with the University of Colorado.
The new findings may help forest managers as they plan logging projects, especially in areas where there is a need to protect high-value trees — in developed recreation areas or on private property.
The study was published online in the journal Functional Ecology. While the current pine beetle epidemic has slowed dramatically in many areas, it wiped out millions of trees across 3.4 million acres since 1996. Continue reading
