St. Louis City, MO had 121 acres managed as woodland or forested natural areas: 98 acres in Forest Park and 13 acres in O’Fallon Park. In Forest Park, standardized Missouri forest vegetation monitoring plots were started in 1993 to develop and guide habitat management such as thinning, species richness development, etc. In 2018 and 2019, a holistic Natural Resources Management Plan (NRMP) for Forest Park provided additional recommended metrics and monitoring, some of which have already begun implementation.
