Media Advisory: How are Louisiana Wetlands Changing?

New Map Shows Losses and Gains Since 1932


Bookmark and Share

Coastal Louisiana has lost a wetland area the size of Delaware, equaling 1,883 square miles, over the past 78 years, according to a new U.S. Geological Survey National Wetlands Research Center study.

A new map that illustrates wetland losses and gains on the Louisiana coastline from 1932-2010 has been developed by the USGS National Wetlands Research Center. This product provides opportunities to better understand the timing and causes of wetland loss, which are critical for forecasting landscape changes in the future. 

The USGS map can be used to help inform land managers on ways to manage this national treasure to become a more resilient ecosystem. Coastal Louisiana wetlands support the largest commercial fishery in the lower 48 states and provide critical habitat to many threatened and endangered species. The delta is the seventh largest on Earth and the wetlands help to buffer populations and property from hurricanes and other storms.
