The Sierra Nevada bighorn sheep (Ovis canadensis sierrae), unique to California's Sierra Nevada mountains, was listed as federally endangered in 2000. The population, which reached over 600 in 2016, has declined to about 300 in 2023 due to mountain lion predation and heavy snowfall. These sheep have specialized hooves for rocky terrain and exhibit distinct seasonal coloration. They inhabit elevations from 4,790 to 14,100 feet, preferring open, rocky areas. Efforts by the California Department of Fish and Wildlife, including relocations and GPS tracking, aim to recover the population, which had dropped to 100 individuals in 1995.
The Bonin flying fox has faced fluctuating conservation statuses over the years. Initially classified as vulnerable by the IUCN in 1994 and 1996, it was deemed critically endangered in 2000, but downgraded to endangered in 2017. The species is endangered due to its limited range of less than 100 km², fragmented habitat, and a population of fewer than 250 mature individuals. Designated a Natural Monument of Japan in 1969, capturing or hunting them is illegal. Population estimates on Chichijima Island dropped from 150 in 1997 to 65-80 by 2002, likely due to agricultural net entanglement, feral cats, and competition with invasive species.
