Previous estimate was 32-38
The Bureau of Land Management has increased the estimate of how many desert tortoises will be displaced by the Ivanpah solar plant in southern California just southwest of Las Vegas. The previous estimate was that there would only be 32-38 tortoises displaced by the development. They now estimate that there will be 140 of the endangered tortoises displaced by the 5.6 square mile development. The new estimate has required the BLM to seek new consultations with the US Fish and Wildlife Service.
Previous attempts at moving tortoises to new locations have resulted in half of the tortoises dying and similar number of resident tortoises dying at the relocation site due to displacement. If this relocation effort has similar results then it would result in 140 dead tortoises.
Tortoises are long living creatures that mature at age 15 and can live up to 80 years or more. They have declined by as much as 90% since the 1980’s due to habitat destruction and increased predation by ravens which thrive in areas where they previously didn’t because of human trash and livestock which die or leave birthing materials in the spring. They also are illegally collected by people who want them as pets. Land development, such as BrightSource’s Ivanpah solar plant, are also becoming threats to their survival.
Ivanpah solar project could displace 140 tortoises.
