About the Maryland Coastal Bays report card

Environmental and cultural change is one constant in the Coastal Bays due to their position at the land and sea interface and as a result of changes occurring similarly in coastal areas throughout the world, such as sea level rise, land conversion, and population pressures. As a result of these changes, there have been major impacts on the health of the Coastal Bays.

The Coastal Bays report card provides a transparent, timely, and geographically detailed annual assessment of Coastal Bays health. This report card will be released each year providing an assessment of the previous year’s health. The report card rates six reporting regions of the Coastal Bays and uses six indicators that are combined into a single overarching index of health.

Health is defined as progress of the six indicators towards established scientifically derived ecological thresholds or goals. A low score therefore means that the region rarely meets the ecological threshold levels. A high score means that the region often meets the threshold levels. This website enables you to explore the report card through the six regions, by the indicators and index, and as an overview of Coastal Bays health.
