Record Effort to Combat Aquatic Invaders in Texas Yields Early Success, Looks to Next Steps

AUSTIN – Efforts to stop aquatic invasive species from taking over Texas waterways are ramping up this spring, made possible through record funding from state lawmakers. Invaders like giant salvinia, zebra mussels and many others blanket waterways and block boating, fishing and swimming, crowd out native species, spoil rivers and lakes, and clog power plant and municipal water pipes. Experts say it’s a huge challenge, but progress is being made, and the public still has a key role to play.

The 84th Texas Legislature provided $6.3 million to the Texas Parks and Wildlife Department for aquatic invasive species management in 2016-2017, an increase from $1.1 million in the previous biennium. Bolstered by this record appropriation, the department has built or expanded partnerships with universities, river authorities, municipal water districts, non-profits, local, state and federal agencies, and other partners to deliver more than 60 projects statewide, including these examples:

Details about this work, including photos and story profiles showcasing various projects, are on the department’s aquatic invasive species management web pages.

With the summer boating season just ahead, the department and its partners will be calling for boaters help to stop the spread of aquatic invasive species like giant salvinia and zebra mussels that can be spread from lake to lake on boats and trailers. Given boats are the primary way these invasive species are spread, boaters need to “Clean, Drain and Dry” their boats, trailers, and gear every time they travel from one waterbody to another. An online video demonstrates the simple steps to properly clean, drain and dry a boat.
