GUIDING DESERT RIVER RESTORATION: MONITORING RESULTS FROM AN EXPERIMENTAL HABITAT RESTORATION PROJECT ON THE SAN RAFAEL RIVER, UTAH
Development of river restoration activities that maintain and enhance essential habitat within constraints imposed by water development and climate change are essential for native fish conservation. However, such restoration is challenging in desert river systems, because water is limited and desert rivers are naturally extremely dynamic. The complexities necessitate an experimental restoration approach. Based on several years of biological and geomorphic research, we designed and implemented an experimental and adaptive restoration plan for the San Rafael River, a desert river in southeastern Utah. Activities included systematic removal of non-native tamarisk trees, planting of native cottonwood trees, placement of gravel in the river channel, and installation of beaver-dam mimicking structures. Here, we report results of two years of monitoring data, use the information to identify effective techniques, and provide recommendations for future restoration efforts. Recommendations include alternative hypotheses about river response to restoration that can be further tested in subsequent restoration phases. Evaluating these alternative hypotheses will help improve restoration on the San Rafael River and inform the science and practice of river restoration in desert rivers in general.
