Riparian and stream degradation is a major threat to water quality, in-stream habitat, terrestrial wildlife, aquatic species, and overall stream health. Conversely, proper management, protection, and restoration of riparian areas decrease bacteria, nutrient, and sediment loadings to waterbodies; lower in-stream temperatures; improve dissolved oxygen levels; improve aquatic habitat; and ultimately improves macrobenthos and fish community integrity. Two 100 foot reaches along a moderately erodible section of Geronimo Creek in Seguin, TX were selected for evaluating the impact of riparian revegetation as a restoration technique. One site was re-vegetated, and the other was left in its current condition. Water quality samples pre and post restoration were collected quarterly and after large storms. The impact of the re-vegetation was evaluated using the Bank Erodibility Hazard Index (BEHI) and cross section changes with time. pH, electrical conductivity, total suspended solids (TSS), and dissolved oxygen data was also used to evaluate the restoration. Preliminary findings will be presented in this presentation.
