New JFSP Brief – Rising Temps Trigger Ecological Changes in the Boreal Forest of Alaska

Key Findings:

1.  Understory or overstory Composite Burn Index (CBI) ratings for 10 fires were not substantially affected by slope aspect, and elevation, but for two of the fires, results related to timing, or burn season, were significant.

2.  Within the next 50 years, simulation results indicate that boreal forest vegetation will likely shift from primarily spruce-dominated to deciduous-dominated.

3.  Despite the shift to less flammable species, simulation results predict an increase in fire frequency and number of acres burned annually.

4.  ALFRESCO model simulations and changes in the projected cumulative area burned suggest a general rise in fire activity through the end of this century, with the most rapid change in fire activity occurring in the next 20-30 years.

“Projected Vegetation and Fire Regime Response to Future Climate Change in National Parks in Interior Alaska”

Excerpt from: Loya, W., Springsteen, A., Barnes, J., and S. Rupp. Projected Vegetation and Fire Regime Response to Future Climate Change in National Parks in Interior Alaska. Alaska Park Science 10:1 (22-25).

Climate change presents a significant challenge to managing our natural and cultural resources. Ecological models that project effects of climate change on plants, animals, and other system components can be used by managers to understand how these effects will impact park resources.

New findings from the 2007 Anaktuvuk River Fire revealed just how much carbon was  released into the atmosphere from this single fire and the potential role tundra fire disturbances play in feedbacks driving global climate change.
