Seasonal variations in the presence of water is common at many small springs in Mojave National Preserve; some may go dry during periods of drought. Each fall, volunteers from all over California, Nevada, and Arizona-including many from Quail Unlimited and the Society for the Conservation of Bighorn Sheep-head to springs in the Preserve to monitor water supplies used by wildlife. The 2012 Spring Snapshot Survey will take place from September through November. The National Park Service is seeking volunteers with four-wheel drive vehicles and GPS units who are willing to visit desert springs, record their observations, and return the information to NPS researchers. This year we will be adding ibutton® data loggers to the survey protocol.
