WV Wetland Rapid Assessment Method (WVWRAM)

Overview

The Water Quality Standards and Assessment Section of DEP has developed a standardized method for rapidly assessing some of the important natural functions of all types of wetlands present in West Virginia. It is called the West Virginia Wetland Rapid Assessment Method (WVWRAM). WVWRAM uses on-site observations and off-site spatial data. This is a regulatory assessment tool for agency staff and environmental professionals. It requires a knowledge of Geographic Information Systems (GIS), wetland soils, plants, hydrology, and stressors.

WVWRAM has two components:

1. GIS tool for preliminary scoring and off-site metrics.
2. Rapid field method for final scoring.

Both components are required for regulatory use, but the GIS tool can be used as a stand-alone for planning purposes.

• Statewide Map of Preliminary WVWRAM Scores

  View mapped wetlands in West Virginia, including wetland types and preliminary wetland function (WVWRAM) scores. Note that West Virginia's wetland maps are based on the National Wetland Inventory, which was mapped in the early 1980's in our area. Many wetlands are only approximately mapped. Smaller, drier, or forested wetlands are often missing from this map. WVDEP hopes to be able to update the wetland maps after LiDAR imagery becomes available for the state.

• Wetlands Decontamination Steps

  It's important to decontaminate all your equipment and tools used at a wetland site to help prevent the spread of disease and invasive plants between wetlands. Just follow these four easy steps to help keep our West Virginia wetlands healthy.​
