Parent Layer: Non-Tidal

Name: MBSS Sentinel Site

Display Field: StreamName

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This layer displays the location of the fixed Sentinel Site in the Choptank River (2000-2014), as surveyed by the Maryland Biological Stream Survey (MBSS, http://dnr.maryland.gov/streams/Pages/mbss.aspx). The goals of the MBSS, which began in 1995, are to assess current condition and changes in ecological resources of Maryland’s 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). Sites in the Sentinel Site Network were chosen in areas with minimal human impacts and have been sampled annually since 2000. At each MBSS sampling location, benthic macroinvertebrates are sampled from a 20 ft2 area with a standard D-net (Stranko et al., 2014). Community composition data is used to calculate a suite of summary metrics that are included in the calculation of a Benthic Index of Biotic Integrity (B-IBI) for the Coastal Plain region (Southerland et al., 2005).
