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.
