G&A Alumnus Authority on Rate of Coastal Wetland Loss

brady-couvillionGeography alumnus Brady Couvillion has been widely cited for expressing coastal wetland loss in terms the public can comprehend. In 2011, he expressed the average rate of wetland loss between 1985 and 2010 as equivalent to a football field every hour. Since earning his degree, he has become one of the key players in mapping wetland loss.
