Abstract:Given their large areal coverage, high carbon densities, and unique land surface properties and disturbance regimes (e.g., wildfires), the world’s boreal forests are integral components of the global and regional climate systems. A large portion of boreal forests contains permafrost. In northwestern Canada, the northernmost boreal forests grow on cold and thick continuous permafrost. More southerly boreal forests occur in areas with discontinuous and sporadic permafrost. Using satellite remote sensing in combination with micrometeorological measurements,I will discuss howrapidly changing permafrost conditions affect boreal forest cover along thesouthern limit of permafrost, and how thaw-induced boreal forest cover lossaffects land-atmosphere interactions in the southern Taiga Plains ecozone,Northwest Territories.
