AUSTIN – In 2017, the 85th Texas Legislature provided $6.3 million to the Texas Parks and Wildlife Department for aquatic invasive species management in 2018-2019. With this and previous investments, the department has continued to expand prevention and control efforts against aquatic invasive species like giant salvinia, zebra mussels, giant cane and many others that cause environmental and economic harm to Texas.

In cooperation with universities, river authorities, municipal water districts, non-profits, local, state and federal agencies, and other partners, during this time TPWD has delivered more than 60 aquatic invasive species management projects statewide, including these examples:

64 high-risk lakes were monitored to aid in early detection of invasive zebra mussels
