A major spruce beetle outbreak has been spreading across forests of southwest Colorado, but that hasn’t been a big factor in recent wildfires in the region, according to CU-Boulder research.
Climate, topography likely more significant, researchers say
Colorado researchers have added another chapter to the long-running debate over beetle-kill and wildfires, finding that spruce beetle infestations haven’t increased the severity of wildfires in southwestern Colorado.
Spruce bark beetles have affected roughly half a million acres of Engelmann spruce and subalpine fir forests across the state in recent years, with infestations documented across an additional 87,000 acres in 2014. Continue reading

‘Fire is not destroying our forests, rather, it is restoring these ecosystems …’
A group of scientists has weighed in on the political tug-of-war over forest policies by writing a letter to the U.S. Senate and President Obama, warning that two bills currently on the table would be destructive to forest ecosystems and wildlife
At issue are House Resolution 2647 and Senate Bill 1691, both proposed in response to ongoing concerns about forest fires. But the measures won’t improve forest health or reduce fire risks, the scientists said. Instead, the laws are aimed at short-cutting environmental studies, reducing public involvement and preventing courts from enforcing environmental laws.
The role of the timber industry in federal forest management would also unfairly increase under the deceptive guise of promoting decision-making by “collaborative” groups, the scientists wrote.

Budget ‘borrowing’ reaches $700 million as political gridlock prevents meaningful budget reform

With wildfires still raging across the West, the U.S. Forest Service has already used up its firefighting budget for the year. This week, the agency notified Congress that another $250 million will be needed to cover the spiraling costs.
Subsequently, top cabinet officials sent a formal letter asking Congress to change the way the nation pays for firefighting so that the Forest Service and Bureau of Land Management can invest in forest and rangeland restoration, and make lands less vulnerable to catastrophic wildfire.

Drying grasses and shrubs up fire danger in parts of Colorado
FRISCO — Summer may be winding down, but the wildfire season is not over yet. In the past ten days, fire managers and park rangers at Rocky Mountain National Park have responded to four illegal, escaped campfires.
All four were quickly extinguished, each burning less than 0.25 acres, but park managers say they all had the potential to spread quickly and threaten lives and property. Continue reading

Giant fires, insect outbreaks could be ‘game-changer’ for some forests
FRISCO —Forest Service researchers say “mega-disturbances” like giant wildfires and insect outbreaks are likely to hasten the slow demise of temperate forest ecosystems in the coming decades.
Even without those large-scale events, some forests appear to be transitioning to shrublands and steppe, and big disturbances could speed that process, according to a new study published this month in Science. Continue reading

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

New study tracks regional nuances, global trends
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.
