Wetland Loss

Wetlands have historically provided habitat for many Rio Grande fauna including birds, fishes, and other migratory animals. They also provide water for plants that depend on groundwater. They are important in filtering water and maintaining water quality.

How is it measured?

Wetland loss is scored by calculating the change in wetland area over four years (2016 to 2019) using data from the National Land Cover Database.
