TRRP is concerned with a number of invasive species issues on the Trinity River. Channel rehabilitation actions employ various measures to reduce weedy exotic plants. Wetland enhancements are designed both to benefit native species such as Western Pond Turtle and to reduce the prevalence of the invasive Bull Frog. These and other invasive species issues are a focus of the Riparian and Wildlife Work Group.
