Re-greening a Dryland Watershed
The installation of thousands of rock detention structures in the Turkey Pen Watershed, of the Chiricahua Mountains in SE Arizona, provided a 30-year case study to consider low-tech and low-cost Natural Infrastructure in dryland watersheds. The USGS systematic study, through observation and experiment, offers verifiable data that documents their efficacy as a Nature-based Solution, that can provide climate adaptation and mitigation benefits here in the Chiricahua Mountains and beyond.
