Below is a very preliminary and incomplete list of non-native plants that have been observed spreading out of cultivation in Marion County. Some of these are aggressive invaders that are extreme hazards to our landscape, whereas others are only trivial nuisances. Some of these plants have created serious problems in other regions, but have not yet done so here. Some are common lawn and garden weeds that only move into disturbed soil. Many are valuable horticultural or agricultural species that are beneficial in the right places, but interfere with appropriate management of native vegetation if allowed to grow on natural lands.

The species highlighted in yellow are the invasives currently of greatest concern to Marion County public land managers. Cogongrass, highlighted in orange, is the focus of MCISMC's efforts.

The Florida Exotic Pest Plant Council's 2005 rankings of the most invasive species are given in the right-hand column. 

We are currently seeking funding to expand this table, adding all reported species, describing their status in Marion County, evaluating the risks they present here, and providing information on identification and control. If your organization  might be able to support any of this work, please contact Linda Duever at ConwayConservation@conway.com.
