Alaska's Changing Wildfire Environment s an outreach booklet that takes a broad look at how wildfire has been changing in the 21st in relation to climate change.
This AFSC research brief takes a look at early Alaska fire history from the 1940s. The "Zombie" Fires of 1942 is a historical narrative of an exceptional fire event releated to the Alaska Railroad, including an early description of a holdover fire burning over winter.
Alaska's Fire Environment: Not an Average Place is a compilation of excerpts from the keynote presentation given by Robert "Zeke" Ziel at the Albuquerque location of the 2019 Fire Behavior and Fuels Conference.
Alaska is nearly 18% of USA landmass. Its size is often unappreciated, as it’s frequently shown in whole without other states as reference.
Report from the three-day Remote Sensing workshop held at the University of Alaska Fairbanks from April 4-6, 2017. The interagency, international workshop was hosted by the Alaska Fire Science Consortium (AFSC) with funding from the NASA Applied Sciences Program to bring sciences users and producers together to explore new opportunities for applied remote sensing research in boreal and arctic fire management.
Trends in regional fire cycles for Alaska, 1943-2016, were analyzed by Thomas Paragi, Alaska Department of Fish & Game, Maija Wehmas, Alaska Fire Science Consortium, and David Verbyla, University of Alaska Fairbanks.
The research is highlighted in an AFSC research brief and accompanied by a detailed report with methodology/figures and tables.
GIS data and Python scripts from the project are available.
In this Research Brief, Robert Ziel highlights and defines different aspects concerning the science of fire hazard, potential, and risk to provide a concise handout that was made in conjunction to the 2019 Spring Fire Science Workshop by identifying the different fire potential assessment efforts and comparing them with the assessment tools available.
Caribou herds in North America seem to be declining. Is warming climate or it’s effects on habitat to blame? The relationship of caribou to lichen-rich winter ranges and fire is often oversimplified. Many factors besides habitat affect caribou numbers, which undergo large fluctuations naturally. In this Research Brief, we highlight recent publications on caribou-fire relationships and explore some of the factors that make it complicated to predict exactly what will happen and when if old-growth caribou habitats diminish with warming climate and more frequent burning.
It’s hard to keep up with the myriad investigations NASA ABoVE campaign is working on in Alaska. This short research brief is a round-up of recently published fire effects field studies and remote sensing products research and has some LINKS to show you where to access some intriguing new datasets and project results. The “Big Data” coming from ABoVE is going to be a big boost to conducting regional or state-wide fire trends and assessments–you’ll want to know where that data lives.
An update from AKFireInfo about the Livingston Fire mentions smokejumpers setting up sprinklers around 5 cabins about a mile from the head of the fire. This is a common tactic for protecting isolated values at risk, but we did not have good information on how much sprinkling was needed and how long wetting down an area would last. Until now.
Devon Barnes, a graduate student at the University of Alberta, worked with BLM-Alaska Fire Service Fire Ecologist Eric Miller to measure the effect of sprinkling on interior Alaska feathermoss fuel beds. Their work found that it takes 0.8 inches (20 mm) of sprinkled water to bring the top 5 inches of duff to saturation. This takes about 7 hours of sprinkling with a Mark 3 pump at a low throttle, and uses about 2 gallons of gas. Devon and Eric estimate that the sprinkled area can resist ignition by firebrands and surface spread for about 3 days in typical summer weather. The area may of course dry more quickly in very hot and windy conditions.
There are at least 5 important factors that lead Alaska fire managers to continue their use of the Canadian CFFDRS system of fire danger and fire behavior tools for fire potential assessments in Alaska. Fire behavior expert Robert “Zeke” Ziel gives a succinct review of them in this illustrated 3-page report. Essential reading for anyone involved in fire management here in the 49th state!
