Surface-water resources are sparsely distributed on the desert landscape but are critical for the persistence of native flora and fauna—including many endemic species—in the Mojave and Great Basin deserts. Springs are the most numerous surface-water habitats in the Mojave Desert Network parks.
Network staff monitor about 240 springs in the network parks by visiting a statistically-selected sample of springs (approximately 120) each year. During these site visits we measure water quality, water quantity, riparian vegetation, and site disturbance. Sensors are also deployed in a small number of springs to monitor the timing of wet and dry periods.
Join Logan and Marisa from the Mojave Desert Inventory and Monitoring Network for a day in the field monitoring desert springs. Learn why these springs are so critical to desert ecosystems and how scientists study these special places.

Reports, Publications, and DatasetsMonitoring protocols describe why and how we collect, manage, analyze, and report monitoring data about the network's Vital Signs. Each protocol consists of a narrative and an associated set of standard operating procedures (SOPs).
Monitoring reports summarize data and findings from our Vital Signs monitoring activities, and monitoring data include final datasets, data packages, and metadata.
