Conservation Groups Warn Against Approval of Ivanpah Projects

Image
Defenders of Wildlife this month warned the Department of Interior that its pending approval of two large-scale solar projects in the Ivanpah Valley would destroy irreplaceable desert habitat and degrade an important wildlife linkage , despite smarter alternatives .  In a separate letter, the Nature Conservancy noted that Interior's approval of the projects would ignore science-based guidance on how to manage public lands and minimize impacts of energy projects. The two solar projects - First Solar's Silver State South and Sateline projects - would be built on the California-Nevada border on a narrow corridor of habitat that connects different populations of the beleaguered desert tortoise.  A loss or degradation of this habitat linkage would make it more difficult for the desert tortoise to recover from the downward spiral it has experienced over the last half century, and erode its resilience as it faces a host of human threats, including climate change.  Conservationists

Amargosa Toad

I had the distinct pleasure of meeting a rare desert amphibian this month, thanks to the folks at Basin and Range Watch .  The Amargosa toad lives along a roughly ten mile stretch of the Amargosa River and associated springs in the Nevada desert.  The toad's habitat is threatened by human development and pumping of water resources, but luckily some local residents and the Nature Conservancy are working to preserve some of its habitat along the river. An Amargosa toad (Bufi nelsoni) sits relatively camouflaged along a rare source of water in the desert. The BLM in 2006 considered auctioning off thousands of acres of public lands along the Amargosa River, which would have threatened its habitat with construction activity and more water pumping. Although this toad only inhabits a small stretch, the Amargosa River actually stretches about 185 miles from Nevada into the Mojave Desert, just east of Death Valley National Park, and supports an array of wildlife, including migratory b

BLM Urged to Preserve Ivanpah Linkage

Image
In a rather strong and thorough letter, the US Fish and Wildlife Service (FWS) in November asked the Bureau of Land Management (BLM) to reject First Solar's Silver State South solar project in the Ivanpah Valley, reiterating FWS concerns that the project will reduce or eliminate a critical linkage for the threatened desert tortoise.  FWS' letter preceded a joint letter submitted in December by eight different environmental groups asking the BLM to suspend approval of any additional projects in the Ivanpah Valley until a conservation plan is in place, indicating that BLM decisions impacting the Ivanpah Valley so far have underestimated its biological importance. FWS Comments on Silver State South Solar FWS's asks the BLM to work with the applicant to modify the layout of the project if it is not possible to reject the project altogether, suggesting the alternatives already analyzed by BLM do not offer a sufficiently wide habitat linkage. Human development to the west,

Two Reports Highlight Ecological Importance of Ivanpah Valley

Image
Two separate reports from the Nature Conservancy and the Renewable Energy Action Team indicate that the Ivanpah Valley is important to the ecological health of the Mojave Desert, suggesting the area is not suitable for destructive solar facilities.   The Ivanpah Valley is currently the focus of concerned citizens since at least three massive solar facilities could destroy over 20 square miles of pristine desert in the area, and displace or kill hundreds of endangered desert tortoises.  Many argue that rooftop solar installations--not remote facilities on public land--should be the centerpiece of renewable energy policy. Solar facilities targeting the Ivanpah Valley: Ivanpah Solar Energy Generating System: Under construction by BrightSource Energy LLC, NRG, and Bechtel, with financing from Google. (5.6 square miles) Stateline Solar power project: Proposed by First Solar LLC (3.4 square miles) Silver State North and South: Proposed by First Solar LLC. BLM approved a portion of the
