The desert tortoise population continues to experience a significant decline, despite 26 years of recovery efforts under the Endangered Species Act.  Since 2004 - years into the recovery effort - the overall population has declined by nearly 32% , and the decline is even steeper in certain portions of the tortoise's range. This startling trend is not evident in the Department of Interior's public posture, which is optimistic on the ability of landscape-level planning to protect habitat linkages and project-level mitigation to offset local population losses.  A closer examination of land management and mitigation practices calls into question Interior's resolve to arrest the decline of the desert tortoise as its habitat becomes increasingly fragmented. Tortoise Population Spirals Downward When the desert tortoise was listed as threatened under the Endangered Species Act in 1990, initial research and anecdotal evidence suggested human impacts were chiefly responsib...

NextEra Energy is proposing to build a 250 megawatt solar project in Nevada's Pahrump Valley that would destroy 4.6 square miles of intact desert habitat on public land.  The project would further push the distance that residents of the Las Vegas area will travel to experience desert wildlands not scarred by industrial-scale energy projects.  The Ivanpah, El Dorado, and Moapa areas to the south and north of Las Vegas have lost approximately 21 square miles of desert habitat to industrial-scale solar development in the past few years. Approximate area under consideration by NextEra for the Yellow Pine Solar project in the Pahrump Valley.  The total application area covers over 9,000 acres, and the final project would destroy approximately 3,000 acres of the parcel. Some of the lands being considered for the project host desert tortoises already relocated once from a Clark County sanctuary, meaning the animals that survived the initial translocation will again be je...

The Pahrump Valley, a vast stretch of creosote, yucca and Joshua tree that unfolds as you descend from the Spring Mountains, remains the target of extensive development proposals despite a recent decision to terminate a solar power tower project here.  BrightSource Energy this week cancelled its proposal to build the destructive Hidden Hills solar power tower project on the California side of the Pahrump Valley.  The project would have replaced desert habitat with nearly 5 square miles of giant heliostat mirrors and two 750-tall towers that would have burned birds and insects, as is the case with the Ivanpah Solar and Crescent Dunes power tower projects.  Hidden Hills also would have pumped hundreds of millions of gallons of groundwater over its construction and operational lifetime from an already-overdrafted basin, threatening wildlife that depend on nearby natural springs.  So it is indeed a relief that the project has been withdrawn. The Spring Mountains in ...
