Protecting Texas Lakes and Waterfowl Habitat from Invasive Species
Waterfowl hunters play a crucial role in preserving the health of Texas lakes and wetlands by preventing the spread of aquatic invasive species like giant salvinia and zebra mussels. These species not only threaten native habitats but also impact recreational opportunities and waterfowl hunting access.
The Risk of Aquatic Invasive Species
Invasive plants and animals can easily hitch a ride on boats, trailers, and hunting gear, spreading to new water bodies where they can cause significant harm. Giant salvinia, for example, doubles in size in less than a week, forming thick mats that block access to prime hunting areas and outcompete native plants that waterfowl depend on for food and habitat. Similarly, zebra mussels attach to boats and equipment, causing costly damage to water systems and littering shorelines with sharp shells.
Currently, giant salvinia is found in 25 East Texas lakes and various rivers and marshes, while zebra mussels have infested 37 lakes across seven river basins. The potential for these invaders to spread makes it essential for hunters to take preventive action.
Simple Steps to Prevent the Spread
Hunters can help protect waterfowl habitats by following these steps every time they leave the water:
Clean: Remove plants, debris, and mud from boats, trailers, decoys, waders, and other equipment.
Drain: Empty all water from boats, live wells, and other containers, including bait buckets.
Dry: Allow all equipment to dry completely before traveling to another lake or wetland.
A short video on the Texas Parks and Wildlife Department (TPWD) YouTube Channel provides additional guidance on properly cleaning, draining, and drying gear.
Legal Requirements for Hunters and Boaters
Texas law prohibits the transport of invasive species, with fines of up to $500 per violation. Boaters are required to drain all water from their vessels and onboard receptacles before leaving or approaching a freshwater body. Removing invasive plants from boats, trailers, and tow vehicles is also mandatory.
Reporting Invasive Species
TPWD monitors invasive species across the state, but the public can help by reporting sightings of invasive plants or mussels in new locations. If you spot an invasive species on a lake or on equipment being moved, contact TPWD at (512) 389-4848 or email photos and location details to aquaticinvasives@tpwd.texas.gov.
Protecting Texas Lakes for Future Generations
By taking a few simple steps, hunters can help stop the spread of aquatic invasive species and protect the habitats that waterfowl and other wildlife rely on. These actions not only preserve ecosystems but also ensure the continued enjoyment of hunting and recreation on Texas lakes.
