The Florida Fish and Wildlife Conservation Commission (FWC) is set to begin aquatic plant management on Lake Okeechobee from July 28, subject to weather conditions. This initiative will focus on managing 2,500 acres of torpedograss in the Indian Prairie and Steamboat marshes located on the northwest and western sides of the lake.
Torpedograss is classified as a Category 1 invasive species, which can displace native species and alter ecological functions. The FWC will use helicopters for this large-scale project, guided by the Lake Okeechobee Fish, Wildlife and Habitat Management Plan developed in 2022.
Lake Okeechobee serves as an important habitat for various species including the endangered Everglade snail kite, wading birds, waterfowl, and other marsh species. Managing torpedograss aims to improve forage availability for these species while also enhancing access for anglers and hunters. The invasive grass forms dense mats that hinder fish and wildlife usage.
The herbicide imazapyr will be used to manage torpedograss. It has been approved by both the U.S. Environmental Protection Agency and Florida Department of Agriculture and Consumer Services for use in water bodies. There are no restrictions on fishing, swimming, or drinking in affected areas post-treatment.
The proposed management areas have received approval from the Lake Okeechobee Aquatic Plant Management Interagency Task Force, comprising state and federal agencies with public input.
FWC employs an integrated management approach across Florida’s lakes and wetlands using techniques such as herbicides, prescribed burning, and occasional drying events during low water periods.
