Invasive plants in Florida, non-native species introduced to the state, carry significant impacts. They:

  • Displace native species
  • Cause extensive economic harm to the state’s ecosystems and agricultural sectors
  • Clog drainage canals
  • Contribute to erosion
  • Alter Florida plant communities
  • Pose an estimated annual agricultural loss of $179 million.

    Invasive plants, which are often non native plants, considerably threaten native species by outcompeting them for resources and habitat. This intense rivalry may result in less species diversity, possibly driving native animals away or even leading to their extinction.


    Managing these invasive plants costs taxpayers around $30 million to $45 million per year. Category II invasive plants are a group of invasive species that have increased in abundance but have not yet altered Florida plant communities to the extent shown by Category I species. The management of these plants, as well as monitoring invasive species lists, is also included in the efforts.

    Identifying Common Invasive Species in Florida

    Among the most problematic invasive plants in Florida are:


    • Skunkvine: bears small, light grayish pink or lilac flowers and can reach up to 35 feet in length, posing a significant threat to native plant communities.
    • Australian pine: displaces native vegetation and alters natural habitats.
    • Melaleuca tree: forms dense stands that can displace native plants and alter water flow in wetlands.
    • Old World climbing fern: forms dense mats that smother native vegetation and alter fire regimes.




    Each of these species has the potential to out-compete native species, alter habitats, and cause economic and environmental damage. Some invasive species in Florida include:


    • Australian pine, which can reach heights of up to 150 feet and contributes to the alteration of native plant communities and the displacement of native species
    • Melaleuca tree, distinguished by its considerable height and unique brownish white, multi-layered papery bark, poses a threat to Florida plant communities
    • Old World climbing fern, characterized by long unlobed leaflets and thin, wiry vines, is known for altering native plant communities in Florida.

    Identifying these invasive plants early is key to halt their spread and lessen ecological damage. Recognizing these plants’ traits helps distinguish them from native species and can expedite prompt management actions. By displacing native flora, disrupting habitats, and jeopardizing biodiversity, these invasive species pose challenges to Florida’s ecosystems.


    These challenges emphasize the need for efficient management and control strategies to safeguard the environmental health of the state.

    Strategies for Managing Invasive Plants


    Florida implements various measures to prevent the spread of invasive plants. These measures include:

    • Decontamination of boats and equipment
    • Removal of invasive species before dispersal
    • Recognition education
    • Physical and cultural control methods like hand-pulling, drawdowns, flooding, burning, dredging, and shading

      Decontamination procedures help in the early detection of invasive plants by preventing their unintended spread. Additionally, early detection and rapid response protocols are utilized, helping to protect Florida’s natural communities from the negative impacts of invasive plants.


      mowing, tractor, mow


      In terms of control, Florida employs a wide range of techniques, including:

      • Mechanical methods such as mowing and hoeing
      • Use of herbicides for shrubs
      • Environmentally conscious approaches like Integrated Pest Management, which aims to manage invasive species in a way that minimizes risk to people and the environment.

        Invasive plant management strategies can be applied to minimize the disturbance of soil and canopies. These include control methods that focus on minimal disturbance, such as hand-pulling and careful placement of physical barriers. Strategic use of these methods can help maintain soil integrity and minimize canopy alteration, allowing forestry activities to manage invasives while preserving the ecosystem.

        Restoration of Native Plant Communities

        Restoring native plant communities in Florida offers advantages including the promotion of interactions between species, preservation of biodiversity, and provision of ecosystem services and wildlife habitat.


        The process for restoring these native plant communities is well-documented and can be found in the manual developed by The Nature Conservancy for the Florida Department of Environmental Protection. Native plants in Florida that are well-suited for restoration projects include:


        • Baccharis dioica
        • Dalea carnea
        • Fagus grandifolia
        • Gaillardia aestivalis


        These plants significantly contribute to the restoration of native plant ecosystems and help preserve Florida’s natural areas. There have been several successful instances of native plant community restoration in Florida. The Wetlands Committee, for instance, has effectively restored stormwater ponds and wooded nature areas with Florida native vegetation. Additionally, there is a noteworthy restoration project in Lake County for the Zone 9 Sandhill plant community.

        Legal Framework and Reporting Systems


        There can be legal consequences, including fines, if invasive plants in Florida are not controlled. Chapter 5B-57 explicitly prohibits the following activities without a permit:

        • cultivation
        • introduction
        • collection
        • transport

        Non-compliance can lead to penalties. With laws and programs in place, including statewide coordination and funding by the Invasive Plant Management Section, Florida actively manages invasive plant species. The state’s approach is both legislative and administrative, with the goal of controlling the spread of invasive plants. The EDDMaPS Invasive Species Mapping System serves as a crucial tool for documenting invasive species. It facilitates:

        • The submission of observations
        • Viewing of results
        • Maintenance of personal records
        • Data visualization through interactive maps

        This system enhances tracking and monitoring efforts of Florida fish in Florida.
