This month, contractors will begin the annual control efforts to manage Arundo along the Pedernales River and several tributary creeks. Arundo, also referred to as Giant Reed or Carrizo Cane, is a non-native, invasive plant that can take over creeks and rivers.

Since 2016, the Texas Parks & Wildlife Department (TPWD), Hill Country Alliance (HCA), City of Fredericksburg, and other organizations have partnered with volunteering landowners through the Healthy Creeks Initiative to control Arundo and enhance the creek-side (or riparian) habitat along Barons Creek, Town Creek, and other portions of the Pedernales River Basin primarily upstream of Johnson City.

This invasive plant has the potential to significantly damage the health of Hill Country streams and rivers by worsening flooding, displacing native plants, destabilizing banks, contributing to erosion, degrading fish and wildlife habitat, and increasing wildfire risk.

Daniel Oppenheimer, Land Program Manager at Hill Country Alliance, notes, “Landowners should not cut, mow, or bulldoze Arundo. These mechanical methods are likely to spread Arundo infestations to downstream neighbors through small fragments of the cane or root material.”

Over the past five years, more than 115 landowners have volunteered to participate in the Healthy Creeks Initiative to control Arundo in the Pedernales River Basin using targeted, aquatic-approved herbicide application. This control method has the least impact on the stream ecosystem and is currently being provided at no cost to the landowners.

Oppenheimer encourages landowners to talk with their neighbors. “This invasive plant does not care about property boundaries. We need to be talking with friends and neighbors, making sure everyone knows about the threats posed by Arundo, the no-cost opportunity provided by TPWD to landowners, and the importance of our healthy riparian areas.” Healthy riparian areas comprised of diverse and abundant native plants mitigate floods, improve water quantity and quality, stabilize banks, reduce erosion, and provide fish and wildlife habitat.

If landowners think they may have Arundo growing on their property or have any questions about the project, please contact either Daniel Oppenheimer at Hill Country Alliance (210-287-0478; or TPWD project staff (; 512-289-2740).

Arundo control efforts for the year will continue through August. To learn more about the Healthy Creeks Initiative, visit Texas Parks and Wildlife’s website at
