​​​Broad-scale Lake and Permafrost Dynamics in the Western Alaska LCC Region

Project Summary

​Project ID: WA2011_02 ​
Lead Investigator: Guido Grosse, Alfred Wegener Institute Centre for Polar and Marine Research; Vladimir Romanovsky, University of Alaska Fairbanks Geophysical Institute​
Collaborators: Tom Dolittle, USFWS; Ben Jones, USGS; Michael Brubaker, ANTHC; David Swanson, NPS
Project Duration: 2011 - 2014

This project assessed changes in lake abundance and size distribution in six major lake districts of the Western Alaska LCC. Land, resource, and wildlife managers, as well as local communities in Western Alaska, need spatially explicit information to determine past lake habitat changes, identify spatial patterns that could be correlated to climate, and project future changes in these important freshwater habitats. Forecasting future changes will assist with developing habitat conservation plans and assessing the stability of freshwater resources for communities.
