Baltimore has a long history of social science research that takes an ecological perspective. This is quite rare, and means that we will be able to very readily connect ecological and physical sciences research with an already well developed understanding of the social organization and processes in Baltimore. Researchers at the University of Maryland, Baltimore County, Johns Hopkins University, and the US Geological Survey are key members of the LTER team. In addition, there are wonderful paleoecological (ancient) records, and great geographic data and historical records. The connection with the Chesapeake Bay is also important. Last, but by no means least, there is a well established and mutually respectful network of interaction between researchers, community leaders, managers, and policy makers. Revitalizing Baltimore and the Parks and People Foundation have been crucial in maintaining these links.
