  1. Linking Regional Carbon Storage to Land-Ownership Changes in the Southeastern United StatesMichael W. Binford1, Grenville Barnes2 and Henry Gholz31Department of Geography, University of Florida, Gainesville, FL 32611, USA, mbinford@ufl.edu2School of Forest Resources and Conservation and Geomatics Program, University of Florida, Gainesville, FL 32611, USA, gbarnes@ufl.edu3Division of Environmental Biology, National Science Foundation, 4201 Wilson Blvd., Arlington, VA 22230, USA, hgholz@nsf.gov UF SFRC UF GEOG Effects of Timber Price: Carbon storage for nearly all ownership types, and all ownership trajectories was indifferent to pulpwood price. Timber companies hold vast areas of land and cut a small fraction each year regardless of pulpwood prices. Other owners are not, in general, motivated by timber sales. Hypothesis 2 is rejected. Conclusions and Perspectives The US national forest-products industry has undergone significant changes since the 1980’s, especially the creation of TIMO and REIT ownerships that may or may not have the same management objectives of the traditional timber companies (e.g., Smith et al. 2009). Most of the conversion of vertically integrated timber companies has occurred since 2000. The results of our study, while standing on their own, may be useful as a baseline for comparing how the recent changes in ownership influence carbon stocks and cycling. Research Question: How do both ownership and changes in ownership affect regional carbon storage over time? Hypotheses: (1) changing land ownership triggers premature anticipatory or subsequent cutting and hence decreases overall carbon storage, (2) timber companies would cut more as pulpwood prices rise, which also would decrease overall carbon density, but that other ownership types would be indifferent to prices. Effects of Ownership Type : -T: Density and Total: some fluctuation with general increase -P: Density and Total cyclic (~10-yr?) -C: Density and Total generally drop over time, sharply with sales. Overall totals are low across region. -G: Densities fluctuate with purchases, Total general increase over time, again with purchases.
