Spatial relationships between burn patterns, pre-burn vegetation composition and distribution, and short-term vegetation recovery in Okefenokee National Wildlife Refuge, Georgia (collaborator: Paul Wetzel, Smith College)

fire in Okefenokee Swamp, GA<br />


May 2008 - February 2010


1. Describe fire severity and fire spatial (patch size and shape) patterns based on spatial data currently available from ONWR (i.e., the 2007, 2.5m resolution SPOT panchromatic data).
2. Develop a vegetation classification of newly acquired (this study) satellite imagery with aerial photography and site-based sampling (limited to ground-truthing sites).
3. Compare the burn pattern descriptive analysis with new (this study) and archived (Loftin and McCloskey) vegetation classifications to document short-term vegetation change following the 2007 fires.
