FRISCO — The vulnerability of the world’s forests to global warming has been widely underestimated, a group of scientists concluded after taking a hard look at all the scientific data on forest mortality.

“We expect to see widespread declines in forest productivity, changes in the species composition and dominance patterns of forest trees, a shift to smaller-sized trees, and reductions in forest extent in some regions,” said U.S. Geological Survey researcher Craig Allen, adding that, even forests in wetter parts of the world are going to be affected by rapidly warming global temperatures.

Federal court shuts Tongass national forest roadless loophole

Country’s largest rainforest to be protected from destructive logging

Staff Report

FRISCO — A federal court has overturned yet another lawless environmental decision made by the former Bush administration by striking down a huge roadless rule exemption for logging in Alaska’s Tongass National Forest — thew country’s largest.

Conservation groups hailed the decision by the U.S. Court of Appeals for the 9th Circuit as a major victory for efforts to preserve southeast Alaska’s environment. The national roadless rule, issued in 2001, protected about 60 million acres of public lands across the country, which the Bush administration promptly tried to undermine with all sorts of administrative exemptions.

New satellite data aids wildfire efforts

Real-time info and detailed imaging helps firefighter get the jump on dangerous blazes

Staff Report

FRISCO — New satellite-based technologies developed by NASA have already helped firefighters in South Africa respond to dangerous wildfires, and could help resource managers in the U.S. get a jump on blazes that threaten communities.

The new fire detection tool uses data from the Suomi National Polar-orbiting Partnership satellite to detect smaller fires in more detail than previous space-based products. The high-resolution data have been used with a cutting-edge computer model to predict how a fire will change direction based on weather and land conditions. Continue reading

Climate change contributes to longer fire seasons worldwide

New study tracks regional nuances, global trends

Staff Report

FRISCO — U.S. Forest Service scientists and other researchers say there has been a significant increase in the length of wildfire seasons on nearly every continent, with the exception of Australia. Fire weather seasons around the globe have increased by nearly 20 percent and the global burnable area doubled over the past 35 years.

Most vegetation types, except boreal forests, showed significant increases in the fire weather season length, the new study found. Some areas, such as the Western and Southeastern United States, Alaska, tropical and sub-tropical South America and Eastern Africa and large parts of Eurasia show a steady lengthening of the fire season from 1979-2013.

Summit County: Frey Gulch restoration begins

Construction of new dirt bike trails also under way

The Forest Service and volunteer partners are simultaneously building new dirt bike trails and closing forest roads in the Tenderfoot Mountain area.

Staff Report

FRISCO — The U.S. Forest Service is implementing restoration plans associated with approval of the new off-road motorcycle trail system on Tenderfoot Mountain.

The trail system, long a local point of contention, was approved last year based on a compromise agreement among stakeholders. The Forest Service has already started building part of the trail, with new single-track visible just a few feet above, and running parallel to Straight Creek Road.

This summer, Tenderfoot Mountain Road (#66.2B) in Frey Gulch will be closed and rehabilitated in order to improve water quality and improved habitat for fish and wildlife. The restoration of Frey Gulch was included as a condition the trail system permit. Continue reading

USFS OKs road to private land at Breckenridge Ski Area

The ultimate ski cabin?

Road construction to a private inholding at Breckenridge Ski Area could begin this summer.

FRISCO —The U.S. Forest Service has authorized construction of a 1,300-foot road across national forest lands at Breckenridge Ski Resort to access a privately owned 10-acre parcel.

The inholding was bought last year by a Breckenridge resident who plans to build a cabin on the tract, located located near the top of the Zendo Chair and base of the Kensho chair on Peak 6. Continue reading

Study: Western pine beetle outbreak may have weakened next generation of trees by wiping out key fungi

Widespread mushroom die-off dramatically lowers seedling survival rate

Staff Report

FRISCO — The recent pine beetle outbreak in western forests may have left the next generation of trees more vulnerable to future pests, Canadian researchers concluded in a new study that examined how the wave of tree deaths affected fungi that grow together with lodgepole pines.

Many trees, including lodgepoles, are partly dependent on certain fungi that enable a nutrient exchange at the cellular level. But the pine beetle outbreak was so widespread that many of the beneficial fungi disappeared. Continue reading
