July 2, 2020 (San Diego)—Once the most common butterfly in Southern California, the Quino Checkerspot Butterfly has lost over 70 percent of its habitat.  It’s been listed as a federally endangered species since 1997, but is not on California Endangered Species Act. That could soon change, if a petition filed this week by the Center for Biological Diversity and the Endangered Habitats League is successful.

The butterfly is now found only in San Diego and Riverside Counties. The petition, filed with the California Fish and Game Commission, would make the colorful butterfly an endangered species under state law, giving stronger protections against habitat destruction and fragmentation, climate change, nitrogen pollution, invasive species and enforcement.

Some populations face extinction threat from freeways, sprawl, rat poison

June 25, 2019 (San Diego) -- The Center for Biological Diversity and Mountain Lion Foundation formally petitioned the California Fish and Game Commission today to protect mountain lions under the California Endangered Species Act.

The petition seeks protections for “gravely imperiled” cougar populations in Southern California and on the Central Coast, including all of San Diego County, the Eastern Peninsular Range as well as Santa Ana Mountains, San Bernardino Mountains, San Gabriel Mountains, Santa Monica Mountains, and north along the coast to the Santa Cruz Mountains.

Traditionally, conservation biologists have relied on field observation and sample and statistical analysis to help them understand the dynamics behind species loss, but today genetics is taking on an increasingly important role in helping quantify the biodiversity around us and even save some threatened species.

February 6, 2012  (Washington D. C.) -- The Interior Department’s U.S. Fish and Wildlife Service (FWS) and NOAA’s National Marine Fisheries Service (NOAA Fisheries), the two federal agencies responsible for administering the Endangered Species Act (ESA), today announced a 30-day extension of the public comment period on a draft policy interpreting the phrase “significant portion of its range” (SPR) in the ESA’s definitions of “endangered species” and “threatened species.”
