The U.S. National Parks Service needed a restoration contractor to assist with the removal of invasive cattails in the ecologically sensitive Indiana Dunes National Lakeshore at the southern tip of Lake Michigan.
Due to the size of the project, rough ground conditions in the once-forested wetland, and due to the significance of the rare Great Lakes ecosystem, the usual methods with ATV, or spot-spraying, or even helicopter broadcast spraying for cattail removal were not an option.
AES deployed a Gulf Coast amphibious Marsh Master with custom spray boom and tank system fabricated in-house, to achieve uniform coverage of invasive cattails but with maneuverability to avoid sensitive native species and communities that the project was intended to save.
The Marsh Master allowed the job to be completed within a two‐week window which would have been impossible or cost-prohibitive with any other application method in such a sensitive site.
The tracked vehicle made from lightweight aluminum has a lighter soil compaction footprint per square inch than an average person standing on two feet.
The fight against invasive species in the upper Midwest wetlands, and throughout the country, is a maintenance challenge that has been escalating in the past couple decades.
At the Indiana Dunes, AES marshaled marsh buggy technology, and field crews with hand-wicking assignments, to effectively control the cattail invasives while protecting precious, rare dunal and wetland vegetation.
