Initiatives for Arundo Control

Arundo donax, commonly called Arundo, giant reed, or carrizo cane, is a highly invasive, non-native grass with the potential to significantly damage the health of streams and rivers by affecting water quality and quantity, worsening flooding, displacing native plants, destabilizing banks, contributing to erosion, increasing fire risk, and harboring cattle ticks and other invasive species such as feral hogs.

Targeted, aquatic-approved herbicide application is used to gain control of significant Arundo infestations. This control method has the least impact on the stream ecosystem and is currently being provided at no cost to landowners in priority areas. Our ultimate goal is to help restore healthy stream function and improve habitats beside and within the creeks. These measures will benefit our state fish, Guadalupe Bass, found only in the Hill Country.

Healthy Creeks Initiative

Through the Healthy Creeks Initiative, TPWD partners with government entities, nonprofit organizations, volunteers, and hundreds of private landowners to implement large-scale management of Arundo on Hill Country rivers and streams. Since 2015, efforts have been highly successful (see project map) and continue to expand to new areas.

Nueces River Basin

Since 2010, the Pull.Kill.Plant. initiative has been a model for successful management of Arundo through building partnerships with riverside landowners. This project is active along the Frio, Dry Frio, Sabinal, Nueces and Leona rivers in Frio, Real, Uvalde, and Zavala counties. The Nueces River Authority leads the project, with support from TPWD.
