The pika, a fist-sized relative of the rabbit, lives in high-elevation boulder fields in the Sierra Nevada and is sensitive to warm weather. The Center for Biological Diversity asked the California Fish and Game Commission to protect the species, citing evidence the pika is declining as its habitat shrinks due to climate change. The commission voted unanimously to reject the petition, calling the evidence inadequate to justify protection.
