The National Wetland Condition Assessment (NWCA) is a collaborative survey of our Nation’s wetlands. The NWCA examines the chemical, physical and biological integrity of wetlands through a set of commonly used and widely accepted indicators.
Though we are aware of the important benefits wetlands provide, we know very little about their actual ecological health. The NWCA is a statistical survey that begins to address some of the gaps in our understanding of wetland health by providing information on the ecological condition of the nation’s wetlands and stressors most commonly associated with poor condition.
The NWCA is designed to answer basic questions about the extent to which our nation’s wetlands support healthy ecological conditions and the prevalence of key stressors at the national and regional scale.
The National Aquatic Resource Surveys (NARS) are a collaboration between EPA, states and tribes to assess the quality of the nation’s coastal waters, lakes, rivers, streams and wetlands. The NARS provide critical, nationally-consistent data on the nation’s waters.
