National Wetland Condition Assessment

Purpose/Objectives

The U.S. Environmental Protection Agency (EPA) will collaborate with state and tribal partners to implement the National Wetland Condition Assessment (NWCA) to meet three goals:

  1. Produce a national report that describes the quality of the nation's wetlands;
  2. Help States and Tribes implement wetland monitoring and assessment programs to guide policy development and project decision-making; and
  3. Advance the science of wetlands monitoring and assessment.

The sampling design for this survey is a probability-based network that will provide statistically-valid estimates of condition for a population of wetlands with a known confidence. It is designed using modern survey techniques. Sample points are selected at random to represent the condition of wetlands across the country.

Description

The NWCA is a statistical survey of the quality of the nation's wetlands. The NWCA is designed to:

  • Determine the ecological integrity of wetlands at regional and national scales.
  • Build state and tribal capacity for monitoring and analyses.
  • Promote collaboration across jurisdictional boundaries.
  • Achieve a robust, statistically-valid set of wetland data.
  • Develop baseline information to evaluate progress.

This is one of a series of water surveys being conducted by the EPA, states, tribes, and other partners. In addition to wetlands, partners will also study coastal waters, wadeable streams, rivers, and lakes in a revolving sequence. The purpose of these surveys is to generate statistically-valid and environmentally relevant reports on the condition of the nation's water resources.
