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.

Wildfires burn record 1.8 million acres in Alaska

Nationally, fires have scorched more than 2.5 million acres

Staff Report

FRISCO — U.S. Wildfire activity has surged above the 10-year average in the past few weeks, primarily because of what will be a record-breaking fire season in Alaska.

After months of mostly above-average temperatures, Alaska’s vast forests and brushlands were primed, and the Alaska Interagency Coordination Center is reporting that more  600 fires have burned across more than 1.8 million acres in the state.

Fires have caused evacuations, highway closures, and rail and flight disruptions. More than 350 structures have been damaged, including about 70 homes.

Above-average temperatures and a longstanding drought in the western U.S. are big factors in the wildfires burning in parts of Washington, Oregon and California.

According to the National Interagency Fire Center, there are currently 26 major fires burning in Alaska. Nationally, the NIFC is reporting that about 26,000 fires have burned across more than 2.5 million acres for the year to-date, the highest number since 2011, when fires had already scorched more than 4.8 million acres by this time of year.

Colorado firefighters speak out on climate change

Short documentary film explores links between global warming and growing wildfire danger

Staff Report

FRISCO — Colorado firefighters who have battled some of the state’s biggest blazes are speaking up about the risks of climate change in a new short documentary film that premiers in Denver this week.

The film links the increase in the number and intensity of Colorado wildfires with climate change. The 7 p.m. showing at the Sie FilmCenter (2510 East Colfax Ave.) is open to the public. Free tickets can be reserved at http://www.denverfilm.org/filmcenter/detail.aspx?id=27436

The screening is presented by The Story Group and Working Films.

In the movie, Rod Moraga, a fire behavior analyst with 26 years of experience, recounts directing firefighting efforts at the 2010 Fourmile Canyon Fire when he realized his own house was threatened. Continue reading

Wildfire season starts slow for 2d year in a row

Continued Western drought, warmth set stage for significant wildfires later this summer

Western wildfires have always been shape-shifting beasts, roaring to life wherever there is hot and dry weather, wind and fuel. But last year’s relatively cool and wet summer brought relief to parts of the region — including Colorado — that had been especially hard the previous few years.

The 2015 wildfire season is starting similarly slow to last year, according to statistics from the National Interagency Fire Center showing that, since January 1, there have been about 6,200 fires that burned across a 100,000 acre footprint, just 30 percent of the average from the past 10 years.

Study: Pine beetle outbreaks not a big factor in the ecological severity of Western wildfires

Study shows no clear link between beetle-kill and ecological severity of western wildfires

Staff Report

FRISCO — For all their frenzied tree-killing during the past 10 years, mountain pine beetles haven’t been a big factor in the ecological severity of wildfires in the West, a team of university scientists said this week.

Weather and topography are the main factors in determining how much damage a wildfire does to forest ecosystems, according to the researchers with the University of Wisconsin-Madison and the Washington State Department of Natural Resources.

The new study, published in the Proceedings of the National Academy of Sciences, provides some of the first rigorous field data to test whether fires that burn in areas impacted by mountain pine beetles are more ecologically severe than in those not attacked by the native bug. The study didn’t look at fire behavior, including how fast they spread or how dangerous they are to fight. Continue reading

New study challenges the conventional wisdom on severity of Front Range wildfires in Colorado

A new study examines the history of wildfires along the Colorado Front Range.

Historic wildfires in the pre-suppression era burned just as intensely, scientists say

Staff Report

FRISCO — New research challenges the conventional wisdom that wildfires along the Colorado Front Range have become more severe.

A detailed assessment of fire history across more 1 million acres of forest suggests that only 16 percent of the area showed a shift from historically low-severity fires to severe, potential crown fires that can jump from treetop to treetop.

Even in the days before fire suppression, fires along the Front Range were often destructive, killing many mature trees in the burn areas, the study concluded. Continue reading
