The Environmental Institute of Houston conducted the National Wetland Condition Assessment (NWCA) for Texas in the summer of 2021. The project is a national assessment coordinated by the U.S. Environmental Protection Agency to meet three primary goals:
- Produce a national report that describes the quality of the nation's wetlands;
- Help states and tribes implement wetland monitoring and assessment programs to guide policy development and project decision-making; and
- 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.
The NWCA is a statistical survey of the quality of our nation's wetlands, and is 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; and
- 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. The purpose of these surveys is to generate statistically-valid and environmentally relevant reports on the condition of the nation's water resources.
