By Haley Dunleavy, PhD Candidate at Northern Arizona University Leaving my house, I feel like a runaway. I am packed inside an economy-sized rental car with my field clothes, camping gear, and of course, face masks, heading 300 miles north to meet my advisor Michelle Mack and fellow lab members for a couple days of… Read more »
As boreal forest wildfires increase in severity and frequency, new patterns of post-fire recovery are emerging. Research led by Jill Johnstone at Bonanza Creek LTER has found that recent wildfires led to changes in tree species dominance that are persisting through post-fire succession in Alaskan boreal forests, indicating the potential for a widespread shift in… Read more »
In 2014, massive wildfires swept through the Northwest Territories of Canada, burning over two million hectares of boreal forest, as well as the highly organic soils on which they stood. Researchers with the Bonanza Creek LTER used this unplanned experiment to learn whether the carbon released from burned land had been recently deposited or if… Read more »
Inspired by several citizen science projects, a team from Bonanza Creek LTER studied how changes to season lengths in Interior Alaska affected native and non-native species.
Researchers from Bonanza Creek LTER developed a framework for boreal forest management that considers climate uncertainty, public safety related to fire regimes, and harvest and biodiversity goals.
If carbon is currency, wildfires are the brokers; that is, they distribute carbon between land and air. In the short-run, fire emits carbon dioxide into the atmosphere. Over time, it also strengthens subsequent carbon uptake through plant regrowth. This exchange is like a natural Ponzi scheme – the carbon offsets from yesterday’s fires take up today’s emissions….

Interior Alaska: black spruce and mosses as far as the eye can see. New research suggests that image may change dramatically over the next century. As the intensity of fires in interior Alaska increases, forest regrowth is shifting from spruce to deciduous species such as trembling aspen and Alaska paper birch. But intense fires also… Read more »
While Florida, Texas, and Puerto Rico recover from a devastating hurricane season, another natural disaster rages on the other side the continent. Following a record-hot summer and dry conditions, the northwestern United States and Canada have experienced one of the most intense fire seasons on record. As global temperatures rise, scientists will need a better… Read more »
Each forest reflects a legacy of past disturbances—from the literal detritus left behind a storm or fire to the prominence of particular species traits that enable species to bounce back after a specific type of disturbance.
Climate-change is predicted to have a larger impact on Arctic regions than on temperate ecosystems. As a result, rural communities relying on local wild resources, or subsistence harvesting, are vulnerable to climate-change-induced environmental trends affecting the availability of fish, waterfowl, and other key resources.
