Description :
This study examines the relationship between vegetation and soil characteristics in an active thaw pond complex on Seward Peninsula in order to determine the mechanistic relationship between thermokarst formation and vegetation change at the forest-tundra boundary. In particular, the AA. address 2 questions : what is the relationship between active-layer thickness, soil drainage, and vegetation? what are the temporal dynamics of tree colonization and mortality in this thaw-pond complex?
