The historic Cajun Prairie once encompassed over 2.5 million acres in Louisiana and Texas and supported a highly diverse community of plants, wildlife, and pollinating insects. Decades of agricultural and industrial practices, urbanization, and land development have nearly eliminated this ecosystem, with less than 0.01 percent remaining. This urban prairie is a green infrastructure project developed through the Campus as a Living Lab initiative for sustainable development. Students, faculty, and staff planted the area with wildflowers, grasses, and shrubs native to Louisiana. Designated as a low mow zone, it is mowed just once or twice a year to encourage restoration of the Cajun Prairie, increase biodiversity, and improve air quality. At its center is an inland storm drain connected to a municipal storm water management system that is part of the Teche-Vermilion watershed. The urban prairie also acts as a bioswale, reducing storm water runoff, improving local water quality, and recharging the groundwater supply in the Chicot Aquifer. The area is carefully maintained to enhance campus beauty and create a habitat for vital pollinators.
