1995 MARYLAND BIOLOGICAL STREAM SITE LOCATION (SITES95)

Description:
The Maryland Biological Stream Survey (MBSS) is a multi-year probability-based sampling program designed to assess the status of biological resources in non-tidal streams of Maryland. The MBSS study area comprises eighteen drainage basins across the state of Maryland, providing biological, water chemistry, and physical habitat data for approximately 300 first- through third-order stream sites per year. 1995 was the first year of full implementation of the MBSS, with all basins to be sampled during 1995-1997. Beginning in 1995, the program implemented a revised sampling design, based on results of the earlier 1994 MBSS Demonstration Project. MBSS 1995 sampling was conducted in six basins: Youghiogheny, Upper Potomac, Lower Potomac, Patapsco, Chester, and Nanticoke-Wicomico. The SITES95 data set contains information describing the location of each site at which samples were collected during the MBSS 1995 sampling year. This information includes spatial coordinates and other site descriptors including the basin, county, physiographic province, stream reach, stream order, sampleability and site type with respect to the study design. Variables in this data set are useful in sorting, stratifying, or otherwise interpreting the other MBSS 1995 data sets.
