Nonnative Weeds Engulf Breeding Grounds Of Mono Lake’s California Gulls

"MONO LAKE, Calif. — The people who guard the gulls that nest on Mono Lake’s islets in the eastern Sierra Nevada have used dynamite, electric fences and lawsuits to protect the birds from wily coyotes and diversions of water to Los Angeles.

Through it all, California gulls returned each year to rear new generations of their species in roughly 25,000 nests.

Now, the gulls are facing a botanical invader they may not be able to overcome: thickets of invasive weeds that have engulfed most of their breeding grounds."
