Eastern USA

We assess the current status (2000) and potential future status (2100) following climate change, of 134 tree species in the eastern United States (east of 100th meridian). We use US Forest Service inventory data with 38 environmental variables to generate models of current suitable habitat for each species. We then change the climate according to three General Circulation Model (GCM) climate models (HADCM3, PCM & GFDL - see 3-GCMs for details) and two emissions scenarios (A1FI (Hi) = little conservation efforts to mitigate CO2emissions, B1 (Lo) = significant conservation effort), and model the potential future species habitats. These two emissions scenarios bracket most of the emission futures as outlined by the Intergovernmental Panel on Climate Change’s (IPCC) evaluation of emission scenarios (Nakicenovic et al., 2000), and end the 21st century at roughly double (550 ppm-B1) and triple (970 ppm-A1fi) the pre-industrial levels of CO2.
