The tortoise, which ranges across southern Arizona and Sonora, Mexico, is the focus of one petition filed jointly by WildEarth Guardians and the Western Watersheds Project. The groups say the tortoise's population has been reduced by more than half since 1987, and that urban sprawl, off-roading and grazing continue to put pressure on the species. In addition, long droughts brought on by climate change are expected to result in less food and lower reproduction rates for the tortoise, the groups say. Rosmarino said drought is also likely to have an impact on the white-sided jackrabbit's grassland habitat. Without federal protection, Rosmarino said, conservationists worry that the tortoise and the jackrabbit
-- like the other species listed in the petitions -- might be lost. She quipped that the tortoise and the hare are not racing each other but are "in a race with extinction and neither of them has an interest in winning that race." __ On the Net: WildEarth Guardians: U.S. Fish and Wildlife Service:
