Research Brief: Is Alaska’s Forest Crossing a Threshold?

 Is Alaska’s Boreal Forest Now Crossing a Major Ecological Threshold?: rb-2013-4-thumbnailRead up on what Alaskan forest and climate research has found out about the influence of warming climate on boreal forests in the Interior!  Here’s a new 2-page Research Brief that digests one of the more significant papers on forest and climate change.  The authors– Dan Mann, Scott Rupp, Mark Olson and Paul Duffy– are well-known to Alaska fire managers. This is a good basis to our upcoming focus on multi-faceted influences of dynamic climate on fire regime, forests, and fire management in Alaska in 2014!     Read More >>  |  Download PDF (861 kb)

Climate, Fire, Frost and the Carbon Bank Research Brief

CarbonBank-pub-thumb

Climate, Fire, Frost and the Carbon Bank: This 2-page research brief summarizes several years of field studies–citing recently published articles–by USGS soil scientists Jennifer Harden and Kristen Manies.  Their studies shed new light on the impact of fires on permafrost in Alaska boreal forest, and  interactions of fire effects and freezing effects on the forest floor.  The insulating moss/duff layer plays a critical role in protecting permafrost and conditions suitable for the rapid regrowth of permafrost are keys to determining whether boreal forest will retain its ability to store large amounts of biomass carbon.     Read More >>  |  Download PDF (1.5 Mb)
