    Wild hogs cause problems at levees because they dig around them, allowing other invasive plants to get established and increasing costs for treating invasives on the levee that normally wouldn’t be there.

    Going Hog Wild

    With their growing population, feral hogs are threatening human, animal and native species health throughout Florida. Their rooting behavior destroys habitat, kills plants and creates disturbed areas where invasive plants can easily grow. They carry diseases that can infect livestock or humans.

    Burmese pythons threaten native species and restoration efforts

    A hunt for Burmese pythons in south Florida is not a hoax; this non-native invasive species is threatening Everglades ecosystem restoration efforts and native wildlife. The one-month ‘Python Challenge’ organized by the Florida Fish and Wildlife Conservation Commission allows anyone older than 18 to hunt the snakes on state land. Burmese pythons are exceptionally difficult to locate, due to their camouflaging capabilities. The ISM branch has initiated efforts to detect the pythons by using dogs and thermal energy remote sensing by an Unmanned Aerial Vehicle (UAV).

    A warmer than normal winter and heavy early season rains contributed to the highest levels of water hyacinth on the St. Johns River and Lake Okeechobee since 1986.

    Invasive Species biologists combat explosion of aquatic plant growth

    The year 2012 brought many challenges for the Invasive Species Management (ISM) Branch to tackle. Multiple factors led to the highest levels of water hyacinth on Lake Okeechobee since 1986. Water hyacinth invades lakes, ponds, rivers, marshes and other types of wetland habitats. According to the Early Detection and Distribution Mapping System website, water hyacinth can reproduce and quickly form dense floating mats of vegetation, sometimes doubling in size over a two week period. These dense mats reduce light and deplete oxygen levels for submerged plants and aquatic invertebrates.
