The Army’s proposal to move 1,000 desert tortoises has been placed on hold by the U.S. Bureau of Land Management, amid concerns over the Army’s previous plan that resulted in the death of 252 out of 600 tortoises.
The Center for Biological Diversity announced that a plan by the Army to move over 1,000 federally and state-listed threatened desert tortoises (Gopherus agassizii) from their Fort Irwin habitat to Bureau of Land Management lands has successfully been halted.

The U.S. Fish and Wildlife Service has announced that they will consider listing the Sonoran desert tortoise as a distinct population.
A 90-day finding on a petition to list the Sonoran desert tortoise (Gopherus agasizzii) as a distinct population (DPS) under the Endangered Species Act has been announced by the USFWS. This announcement has come after the review of filed petitions showed substantial evidence that the Sonoran desert tortoise may meet the criteria of “discreteness and significance” required for distinct population segments.

The Mexican gray wolf population continues to struggle at just 52 wolves. However, listing the species as a “distinct population segment” may hold the key to recovery.
The Center for Biological Diversity issued a press release today to announce that they have filed a petition with the U.S. Fish and Wildlife Service to formally separate the Mexican gray wolf (Canis lupus baileyi) from other wolf populations in the United States and list it as either an endangered subspecies or a “distinct population segment.”
Although a 1982 reintroduction effort along the Arizona-New Mexico line hoped to result in at least 100 wolves in the wild, and 18 breeding pairs by 2006, the most recent survey - conducted in 2008 - found only 52 wolves. Unfortunately, illegal shootings, combined with complaints by ranchers who claim to have lost cattle to wolves (wolves that have been involved in three livestock kills in a year can be killed or trapped by federal agents), have taken their toll on the reintroduction plan.
