Selected Large Springs

Protocol

Importance/Issues

In the Mojave Desert, springs often represent the only surface water over large areas. As a result, springs are extremely important as habitat to aquatic or amphibian animal species and riparian plant species and as water sources to terrestrial wildlife. Springs in the western United States support several hundred endemic plant and animal species, some of which are listed as endangered.

Numerous populations of springsnails, fish, and other species have been extirpated from Great Basin Springs due to anthropogenic habitat changes. The water quality and spring discharge monitoring in this protocol will allow us to detect habitat changes that could threaten endemic and endangered species in the selected large springs in the MOJN parks.

Monitoring Objectives

  • What is the status of and what are the trends in discharge from each of the selected large springs in the MOJN parks?

  • What is the status of and what are the trends in water quality and water chemistry in each of the selected large springs in the MOJN parks?

  • What is the status of and what are the trends in benthic macroinvertebrate communities and springsnail populations in each of the selected large springs?

  • Are water levels in the aquifers associated with the monitored springs changing over time?
