A mile of citizen-funded solar-powered electric fence is up and running, protecting Mono Lake’s nesting gulls—one of the three largest colonies in the world—from mainland predators. The fence is the result of a year and a half of planning by the Mono Lake Committee and California State Parks along with other agency partners, a dedicated local installation team, and generous funding from Mono Lake supporters across the country.
The temporary electric fence stretching one mile across the landbridge has 11 motion-activated wildlife cameras with infrared nighttime flash capability along its length. In late April, camera #5 documented a coyote walking the fence line, confirming that the fence is functioning as a coyote barrier. Mono Lake Committee wildlife camera photo.
Why is the temporary fence—which will be removed when nesting is finished—needed? Five years of drought lowered Mono Lake seven feet, shrinking the protective moat of water between the lake’s north shore and Negit Island and adjacent islets—exposing a landbridge that allows coyotes access to the lake’s long-established nesting colony of California Gulls. Last summer signs were found on a few of these islets that coyotes had indeed walked the landbridge and then swum the remaining 500 feet or so of shallow water to prey on eggs and chicks, disrupting nesting and causing gulls to be suspicious of returning to these sites in future years.
