As it prepares to expand training operations at Ft. Irwin in the Mojave Desert, the U.S. Army is again proposing to move more than 1,100 threatened California desert tortoises -- an unprecedented number of an endangered species that has not fared well during previous relocations.
The Army is seeking the approval of the federal Bureau of Land Management to move the tortoises from nearly 100,000 acres in portions of the National Training Center to lands managed by the BLM. The environmental assessment is under BLM review and the proposed action is open for a 15-day public comment period.
Moving desert tortoises is not always successful. The Army relocated more than 600 of the animals last year but suspended the $8.7-million program after the first phase when officials noted high mortality rates among the tortoises, chiefly because of coyotes.
About 90 animals were found dead from suspected coyote predation. But Clarence Everly, natural and cultural resources program manager at Ft. Irwin, said only one animal died during the relocation.
The sheer numbers of tortoises proposed to be moved in this latest operation, beginning next spring through 2012, alarms conservationists.
"Nothing's ever been done on this scale before," said Ileene Anderson, a biologist with the Center for Biological Diversity, who says a total of 252 tortoises have died in the translocation area. "Every time the animals recognize that they don’t know where they are, they have some built-in mechanism that tells them to head for home and they make a break for home."
In the last move, some tortoises traveled up to five or six miles to get back to their home range, Anderson said.
The relocation of desert tortoises from Ft. Irwin, northeast of Barstow, to the drought-ravaged western Mojave puts more pressure on the species, whose population is already crashing, in part because of an upper respiratory disease that afflicts some animals. Everly said the Army is blood testing every tortoise and will quarantine any found to have the disease.

If you take a block of the four yards around where I live there are 3 houses and one vacant lot. Like this:
OX
XX
The O being the empty lot. In our three houses combined there are 13 kids. The rest of the subdivision is more than 50% vacant. The north end is a charter school K-8. The number of prairie dogs are unimagineable. You can't put your shovel into the ground without government say so. The kids run through the lots and the prairie dogs are so used to it they are nearly tame.
The Utah prairie dog is federally protected. The female is sexually mature at one year of age and she had multiple partners. The females give birth to a litter of 3-4 pups. So while it seems that we procreate rather effectively, we can't keep up with that and we take care of the possibility of life threatening diseases by immunizing our young. These animals carry the plague (of the European black death fame), tularemia, monkey pox and Rocky Mountain Spotted fever. They are silent carriers and an outbreak is possible at any time. Oh and have I mentioned that my mother's oldest brother died at the age of 12 from a disease that he contracted from a prairie dog??
The important thing is that they are safe. After all, people aren't nearly extinct. But I have a really great idea. Leave the tortoises alone. They were there first. The Army can do whatever it is they need to do behind my house. Move the prairie dogs. Our kids? Well they aren't all that important, are they? The Army is actually less dangerous to them.
