Where water meets land – Riparian areas

The Hill Country Steward
By Central Texas Conservation Partnership

Often, when we think about the health of our Hill Country creeks or rivers, our tendency is to look straight down in the channel. Is there any water down there? How much? See any fish?

No doubt, these are important questions. However, by narrowing our focus solely onto what is in the stream channel, we disregard the extensive natural infrastructure that sustains our creeks and rivers. A key part of this natural infrastructure is the riparian zone. 

“Riparian” is not a word we hear too often in Texas—perhaps to our detriment. This term refers to the narrow and verdant vegetated areas along our waterways. These transitional zones between a creek, river, or lakebed and the drier uplands are fairly small, making up only about 1-2% of the Hill Country but crucial to the broader region.

When comprised of a diverse and healthy mixture of plants, riparian zones provide many benefits to humans, wildlife, and livestock. Intertwined roots of grasses, shrubs, and other plants help stabilize creek banks, keeping that part of your property in place. While a deep cradle of roots stabilizes the soil and stream channel, the above-ground plant growth in the riparian zone helps slow down water, storing it in creek banks and the broader floodplain like a sponge for drier times. 

Slowing down water – whether rising flood waters or runoff pouring down a hillside – is an important first domino to stewarding healthy riparian areas. As vegetation, downed tree limbs, and logs left along the banks of riparian zones slow down flowing water, they help mitigate the destructive and erosive forces of flood surges. These areas also trap particles of sediment. Trapping sediment rich in organic matter helps enlarge the floodplain, which in turn absorbs water like a sponge, recharges groundwater, and sustains creek flows.  

It is this domino effect, starting with riparian vegetation, that provides many values we seek as landowners and residents. Values like clean and abundant water, forage for livestock, fish and wildlife habitat, bank stability, and recreational opportunities all emerge from a healthy, functioning riparian zone. What happens in our riparian areas impacts everyone downstream.

Riparian zones are a small, dynamic, and remarkably resilient part of the landscape. Often, if we can identify the stressors (e.g. overgrazing, over-mowing, overabundance of native or exotic deer) and manage them effectively, riparian zones will restore themselves. Sometimes planting native plant species can help expedite the recovery process.

The challenge and opportunity for each riparian land steward is to find the right balance, given their stewardship goals. This could mean maintaining recreational access with targeted access points interspersed by riparian “grow zones,” or possibly limiting the timing, frequency, and / or duration of grazing along the creek to maintain the riparian plant community. Thankfully, there are numerous technical, educational, and financial resources to support riparian land stewards in these efforts.
