The Maryland Biological Survey (MBSS or the Survey) is a comprehensive program of the Maryland Department of Natural Resources (DNR) with the following goals: to assess the status of biological resources in Maryland's non-tidal streams; to quantify the extent to which acidic deposition has affected or may be affecting critical biological resources in the state; to examine which other water chemistry, physical habitat, and land use factors are important in explaining the current status of biological resources in streams; to establish a benchmark for long-term monitoring of trends in these resources; and to target future local-scale assessments and mitigation measures needed to restore degraded biological resources. To meet these and other objectives, the Survey has established a list of questions of interest to environmental decision makers to guide its design, implementation, and analysis. These questions fall into three categories: (1) characterizing biological resources and ecological condition (such as the number of fish in a given area or the number of stream miles with pH<5), (2) assessing the condition of these resources (as deviation from minimally impacted expectations), and (3) identifying likely sources of degradation (by delineating relationships between biological conditions and anthropogenic stresses).
