Our overall project objective is to build on existing interagency efforts at state and federal levels to develop web-based ecosystem service credit calculators using remotely-sensed data and vetted best-of-breed models for both farms (tracts) and watersheds at the 6th-order (12-digit) hydrologic unit level. We will focus on the following ecosystem services: (1) carbon sequestration in woody biomass, (2) water quality (sediment and nutrient loading), and (3) habitat/biodiversity as an undergirding element. Our selected agroecosystem is Southeastern forests, which are at substantial risk for reduced delivery of ecosystem services from both climate and land use change. Our initial implementation area will be the Commonwealth of Virginia with explicit attention on scalability to enable an eventual rollout to other states in the region.
