MBSS IBI Strata

Layer created using Maryland Department of Natural Resources' 8-Digit Watersheds and Marlyland Geologic Survey's Physiographic Province data. MDNR 8-Digit Watershed file divides the state into 138 separate watersheds. MGS physiographic province file was primarily to show divisions between physiographic provinces within the state. The "MBSS IBI Strata" layer is used to determine which of the IBI strata to use for calculations in a given watershed or at a given site(s). For FIBI calculations in the Highland region, the "MBSS Coldwater Stratum" file must be used in determining Coldwater Highlands designations.Acknowledgement of the Maryland Department of Natural Resources and the Maryland Geological Survey would be appreciated in products derived from these data. User may be required to sign a Maryland DNR Spatial Data Products and Services License Agreement.
