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

State Forest Service warns against transporting firewood
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.

Funding shortfall has ripple effect in other public lands programs
By Bob Berwyn
FRISCO — With a dangerous fire season forecast for parts of the country, especially the drought-stricken far West and Southern Plains, federal firefighting agencies will likely once again face a huge budget shortfall. That could require the Forest Service to divert funds from other programs, according to top administration officials who presented the report to Congress.
The report projects firefighting costs of about $1.8 billion, with only $1.4 billion budgeted. The Obama administration is advocating for a budget that would close the gap by giving firefighting agencies the ability to use emergency funds separate from their discretionary budgets to fight fires.
Similar legislation is pending in Congress, where the Wildfire Disaster Funding Act is cosponsored by Sen.Michal Bennet (D-CO) and Senators Mike Crapo (R-ID) and Ron Wyden (D-OR). Continue reading

State report details status of insect activities
Spruce beetles are widely active across the mountains of southern Colorado.
FRISCO — Windstorms, mild winters and drought are the key factors in the continued spread of spruce beetles, which have become the dominant change agent in Colorado forests the past few years.
According to the latest annual forest health report compiled by state forest experts, spruce beetles were active across 398,000 acres in 2013, affected more than triple the amount of acreage than mountain pine beetles. Continue reading
