The goals of the MBSS, which began in 1995, are to assess current condition and changes in ecological resources of Maryland\u2019s 1st through 4th order non-tidal streams, as well as provide an inventory of biodiversity and identify effects of stressors on the natural resources (Stranko et al., 2014). The MBSS is a stratified random survey with a lattice design. Year and basin are included as strata and sampling has been restricted to approximately one-third of the major drainage basins each year (Mercurio et al., 1999). An electrofishing component is utilized to survey fish communities. Community composition data is used to calculate a suite of summary metrics that are included in the calculation of a F-IBI for the Coastal Plain region (Southerland et al., 2005). Established criteria are then used to score the metrics 1, 3, or 5, and the average of all individual metric scores represents the F-IBI (Stribling et al., 1998). The MBSS F-IBI scores can be further classified into four condition ranges: \u201cGood\u201c (≥4.0), \u201cFair\u201d (3.0-3.9), \u201cPoor\u201d (2.0-2.9), and \u201cVery Poor\u201c (1.0-1.9). The F-IBI values for each station and sampling date were coded for condition based on these criteria.", "geometryType": "esriGeometryPoint", "sourceSpatialReference": { "wkid": 102100, "latestWkid":
