The main purpose of this legislation, known as the Building Native Habitats at Federal Facilities Act, is to encourage the use of native plants in federal projects. This aims to enhance environmental sustainability by promoting biodiversity, supporting local wildlife, and improving the ecological health of landscapes managed by federal agencies. Key provisions of the law require federal agencies to prioritize the use of native plants over non-native plants in their construction and maintenance projects, as long as it is feasible in terms of cost, schedule, and availability.
