Louisiana has lost tens of thousands of acres of coastal wetlands in the past half-century, and faces the loss of more coastal wetlands because of sea level increases caused by climate change. The loss of coastal wetlands also hurts the state's protection against major storms, such as Hurricane Katrina in 2005, because the wetlands absorb storm surges and help decrease the impact of hurricanes coming in off the Gulf of Mexico. TPL is working to protect lands along the coast, and slow the loss of wetlands.
In the northeastern corner of Louisiana, TPL is leading an effort to plant trees at the Tensas National Wildlife Refuge. When fully grown, the trees will sequester hundreds of thousands of tons of carbon dioxide, which is the equivalent of taking more than 100,000 cars off the roads. The Tensas region used to be home of some of the largest stands of lowland hardwood forests in the southeastern United States, but the land was completely logged more than 70 years ago.
