Navigating wetlands can be difficult for traditional boats due to the changes in water depth and the amount of mud and muck, as well as the meandering of the waterways. Because of these complications, boats that travel both over land and water are needed to explore coastal wetlands. The creation of airboats and innovations in their design have allowed for greater exploration of wetlands and are vital to CWPPRA’s wetland restoration.
Airboats evolved since their introduction in 1905 by Alexander Graham Bell, who is also credited as the inventor of the telephone. His first model was named the “Ugly Duckling”, a crude test vehicle that incorporated an aircraft propeller mounted on the back of a simple pontoon boat. Over the next decade, further developments turned airboats into World War I reconnaissance vessels. Following the end of the war, commercialization led to a rise in popularity among civilians with companies designing taxis and recreation vessels alongside independent innovators creating their own airboat designs. One of the most revolutionary models was built in 1943 at Bear River Migratory Bird Refuge in Utah and dubbed the “Alligator I”. This design was the first known to use air rudders rather than traditional rudders, and most airboats today replicate the Alligator I’s flat bottom hull with air rudders. [1]
Thanks to the inventors at Bear River, Louisiana’s wetlands are more navigable than ever. Further developments have allowed airboats to pass over land, increased passenger capacity and engine horsepower, allowing those in pursuit of recreation, scientific research, and sport hunting/fishing to reach previously inaccessible parts of our wetlands. CWPPRA teams visit project sites using airboats to help get an idea of problems to be addressed through the duration of projects, ensuring the best quality of restoration for our coast. Restoration and preservation have been made easier with creative solutions like airboats, so we would like to recognize the innovators who worked a century ago to improve upon each other’s designs. Once again, the land loss crisis and need for wetland restoration in Louisiana is too large for us to do it alone. We need all the help we can get from innovators like those at Bear River Migratory Bird Refuge to help restore our coast.

projects require monitoring and evaluation of project effectiveness. There is also a need to assess the cumulative effects of all projects to achieve a sustainable coastal environment. In 2003, the Louisiana Office of Coastal Protection and Restoration (now CPRA) and the U.S. Geological Survey (USGS) received approval from the CWPPRA Task Force to implement the Coastwide Reference Monitoring System (CRMS) as a mechanism to monitor and evaluate the effectiveness of CWPPRA projects at the project, region, and coastwide levels (Steyer and others, 2003). The CRMS network is currently funded through CWPPRA and provides data for a variety of user groups, including resource managers, academics, landowners, and researchers.
