Riparian Management

An easy way to keep Hill Country streams clean and flowing is to use simple riparian management techniques. A riparian area is often described as the “river bank” but in reality it is much more. The riparian area is the interface between land and water along a body of water. It includes the vegetation, soils and features from the water’s edge across the flood plain to the upland area. Typically, the best approach for managing this system is to do nothing, observe and let nature do the work.

Where riparian areas have been disturbed from overgrazing, mechanical lawn mowing, excessive erosion or other alterations to the natural order, restoration MAY be necessary to re-create a healthy functioning system, resulting in more water and cleaner water. The value of riparian preservation/restoration work is immeasurable when you consider the quandary we face with dwindling water supplies throughout the Hill Country. Healthy riparian areas protect water supply in times of drought and slow water velocity in times of flood.

In a nutshell, dense vegetation (native trees, shrubs and grasses) and an active floodplain are necessary to slow water down (dissipate energy) and trap mobile sediment. These are the building blocks of riparian health. Interlaced roots and trapped sediment rich in water storing organic material help to stabilize banks and conserve floodwater. That water recharges groundwater resources and can return to the channel in the form of clean base flow.

The first step toward good riparian management is having an understanding of what a healthy riparian area looks like and how it functions in both drought and flood. On this page you’ll find important links and documents to help educate Hill Country landowners and citizens about proper riparian land management.

Arundo donax and the Healthy Creeks Initiative

Arundo donax, also referred to as Giant Reed or Carrizo Cane, is a non-native, invasive plant that can take over creeks and rivers. 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. Click here to view an informational graphic on Arundo.

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 donax 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. The Healthy Creeks Initiative focuses its efforts within rivers and creeks in the headwaters of the Blanco, Guadalupe, Llano, Medina, and Pedernales watersheds. The initiative focuses on improving riparian health by providing Arundo control at no cost to landowners.

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.

Tips & Tidbits for Hill Country Landowners: Grow Zones and Targeted Access Along Creeks & Rivers

Cover for PDF "Grow Zones and Targeted Access Along Creeks & Rivers"
Across the Texas Hill Country, private landowners, businesses, housing developments and public parks are establishing “Grow Zones” along creeks and rivers to protect the land and water. Grow Zones are specific areas where disturbances, such as excessive mowing and foot traffic, are proactively restricted to allow native plants to thrive.

Riparian Stewardship in the Texas Hill Country: Strategies for Native Plant Restoration

Regardless of the season, it’s always a great time to consider what’s growing on your riverbank! Learn more about strategies for native plant restoration in riparian areas, where land and water meet. Filmed on location at the YMCA’s Roberts Ranch near Comfort, TX, this video features Steve Nelle of NRCS (retired), Ryan McGillicuddy of Texas Parks and Wildlife, and HCA’s Land Program Manager, Daniel Oppenheimer.

Pull. Kill. Plant: Arundo Control & Riparian Restoration in the Nueces Basin

The Giant Reed (Arundo donax) is a well known invasive plant on Texas riversides. Since 2010, groups like the Nueces River Authority  are working to pull and kill the invasive plant to make way for planting native riparian plants on riverbanks along the Nueces and its tributaries. The project is a great example of successful management in partnership with riverside landowners. Click here to learn more. 

Riparian Recovery in the Blanco River

The Hill Country is no stranger to catastrophic flooding, as evidenced by the 2015 Memorial Day Flood. While the region does not always experience severe flooding, we often go back and forth in a cycle between extreme flooding and drought. As our region grows and landscapes are developed for housing and commercial purposes, it is crucial that we take care to preserve our riparian areas. Healthy riparian areas serve as a buffer – they slow floodwaters, stabilize banks, increase recharge into our groundwater resources, and even help to filter water as it rushes by. By following the processes recommended in this videos, landowners can take proactive steps to preserve their riverfront property when severe weather comes our way.
