Maryland Biological Stream Survey Sentinel Sites
Overview
This dataset identifies watersheds that support high quality, long-term monitoring sites important for understanding the effects of environmental and land use change.

Description
The Maryland Biological Stream Survey (MBSS), started in 1995, assesses the ecological condition of 1st through 4th order, non-tidal streams at statewide, basin and watershed scales by measuring key chemical, physical and biological parameters. The watersheds selected for this data layer represent drainages that contain the MBSS Sentinel Site Network (SSN). Certain stream segments within these watersheds are considered to be minimally-disturbed and located in places not likely to experience anthropogenic impacts. Long term monitoring of these sites allows the MBSS to evaluate changes in ecological condition that are primarily attributed to seasonal and annual variations in hydrology and temperature/dissolved oxygen regimes, as well as biotic interactions.
