Aquatic Invasive Species Management

Funding Supports Expanded Effort

Bolstered by record appropriations from the Texas Legislature, Texas Parks and Wildlife Department, river authorities and other partners are waging a war against non-native plants and animals that threaten our waterways.

Addressing a Statewide Problem

Continued Funding in 2018-2019

The 84th Legislature provided $6.3 million to address statewide management of aquatic invasive species in the 2016-2017 biennium. An additional $6.3 million has been provided for the 2018-2019 budget. These investments are expanding TPWD's ability to apply known control methods, fund research into new solutions, and support outreach and prevention.

The impacts of aquatic invasive species are far-reaching and cost Texas billions of dollars each year. Floating plants such as water hyacinth and giant salvinia form dense mats that degrade habitat for fish and wildlife, choke water conveyance structures, and interfere with boating and fishing on Texas lakes. Giant reed and saltcedar proliferate along the banks of creeks and rivers where they crowd out native vegetation, channelize streams, and alter natural flood plains. Zebra mussels colonize beaches with their sharp shells, foul boat propellers, and clog municipal water intake pipes.

TPWD is enlisting the help of boaters, riverside landowners, river authorities, water management districts, and other partners to expand prevention and control efforts across the state. Some highlights are provided in these pages.
