1995 MARYLAND BIOLOGICAL STREAM SURVEY MACROPHYTES (PLANTS95)

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 data set PLANTS95 contains presence/absence data on macrophytes (aquatic plants) found within each 75-meter sample segment during the summer index period. Both submerged aquatic vegetation (SAV) and emergent plant species were recorded. Plants were identified to species level when possible during field observation. Data are from the 1995 MBSS sampling year.
