We used a low cost hobby drone to produce high resolution aerial photographs of a 12 ha mature longleaf pine (Pinus palustris) stand. The photos were combined into orthophoto mosaics and digital surface models to produce repeatable crown maps. Repeated flights allowed the use of tree phenology to separate longleaf from loblolly (Pinus taeda) and pond (Pinus serotina) pines, as well some hardwood species.

New Publication : A minimally managed switchgrass ecosystem in a humid subtropical climate is a source of carbon to the atmosphere.
New publication with our collaborators at Virginia Tech shows that our predictions of net carbon climate benefits from bioenergy crops cannot assume that the ecosystem will always be a net sink of carbon from the atmosphere. The importance of background climate, management, and land-use history, could determine whether widespread deployment of switchgrass as a bioenergy feedstock for climate change mitigation will truly achieve the desired outcome.
