This item contains a service link that returns the count of catchments having moderate risk to habitat degradation in the Northeastern States, which can be used to populate the Current Degradation Chart. In addition, it returns the geometry for the selected catchments, which can be used to spatially display the location of the catchments having moderate disturbance.
The United States is home to a diverse array of freshwater and marine fish, shellfish, and other aquatic species. More than 3,000 species of fish inhabit America’s streams, rivers, lakes, reservoirs, marshes, swamps, bays, estuaries, coral reefs, seagrass beds, shallow water banks, deep ocean canyons, and other watery habitats. The United States is also home to over 300 million people, all depending on the same water that fish depend upon. Healthy habitats are essential for sustainable fish populations. Unfortunately, in many places around the United States, fish and the habitats on which they depend are in decline. Almost 40 percent of the nation’s freshwater fish species are considered at risk or vulnerable to...
Figure 1: This chart displays the Risk of Current Degradation for catchments in the Northeastern United States.
This item contains a service link that returns the count of catchments having very low risk to habitat degradation in the Northeastern States, which can be used to populate the Current Degradation Chart. In addition, it returns the geometry for the selected catchments, which can be used to spatially display the location of the catchments having very low disturbance.
