Desert Springs Monitoring

Overview

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.

Monitoring Objectives

• What are the status and trends of water availability at a subsample of springs in each of the five monitored parks?
• What are the status and trends of water quality at a subsample of springs in each of the five monitored parks?

A Look at the Wet/Dry Status of Desert Springs

Use the repeat photo slider below for a visual comparison the wet/dry status of Sparrow Spring in Joshua Tree National Park. This spring is one of the 45 desert springs in Joshua Tree National Park that were visited during the initial inventory in 2006 and then revisited during the 2016-2017 monitoring field season. We determined that 60% fewer springs had surface water in 2016-2017 compared to 2006.
While this is only a comparison of two field seasons a decade apart, and we do not have enough years of data to detect long-term trends in surface water, our continuing efforts to monitor the Mojave Desert springs will allow us to learn more about these fluctuations over time.

Mojave Desert Network staff interviewed about desert springs!

National Public Radio station KNPR staff interviewed the MOJN program manager and ecologist about the importance of desert springs and why we are monitoring them, along with the vegetation associated with them. Listen as they discuss these vital ecological resources in the network parks in Nevada and what we are learning so far. You can also read a portion of the interview.

Reports, Publications, and Datasets

Monitoring 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.
