The Florida Fish and Wildlife Conservation Commission (FWC) will be conducting aquatic plant management on Lake Okeechobee throughout the week of May 20.

Management areas include the lake’s northwest marsh between Buckhead and Dyess canals. A total of 2,400 acres of torpedograss, a Category I invasive species, will be managed. Due to the large scale of the project, management will be conducted using helicopters. Drones, airboats and argos (amphibious all-terrain vehicles) will be used to conduct treatment in small areas mixed with native vegetation.

According to FWC, torpedograss outcompetes native plant species, creating extensive dense mats that limit fish and wildlife use.  

Torpedograss will be managed with herbicide (imazapyr). Past torpedograss management has shown that once torpedograss dies, native plants quickly germinate and colonize the area. Imazapyr is approved for use in water bodies by the U.S. Environmental Protection Agency and Florida Department of Agriculture and Consumer Services. There are no restrictions related to fishing, swimming or drinking in affected areas of the lake.

The torpedograss management areas proposed by the FWC have been vetted through and approved by the Lake Okeechobee Aquatic Plant Management Interagency Task Force, an advisory group of state and federal agencies with public input on aquatic plant management conducted by the FWC, the U.S. Army Corps of Engineers and South Florida Water Management District on Lake Okeechobee.

Habitat enhancement using multiple selective management techniques, such as herbicides and prescribed burning, coupled with occasional drying events during low water periods, is part of an integrated management approach used by the FWC on many lakes and wetlands throughout Florida.

Management areas will be posted at boat ramps and FWC staff will be present to ensure all agency protocols are being followed. For questions about this project, contact FWC biologist Alyssa Jordan at 863-697-2181.
