Torre Jorgenson leads ABR’s Ecological Land
Survey Program and has directed and participated
in more than 100 Alaska studies involving vegetation
classification and mapping, permafrost and geomorphology,
restoration, bioremediation, climate change, and
wetland science. His most recent research has focused
on the development of ecological land classifications
of military lands and national parks throughout
Alaska, which have employed analysis of satellite
imagery, true-color and infrared photography, ground-truthing,
and GIS spatial analysis to develop maps suitable
for land-use assessments. Torre also has been involved
in assessing effects of global warming on sea-level
rise and ecological changes on the Yukon-Kuskokwim
Delta, coastal erosion along the Beaufort Sea coast,
permafrost degradation in central and northern Alaska,
and monitoring landscape change through repeat photography
in southwestern Alaska.
