The outlook for desert wildlands is dismal under a Trump Administration, and we will have to be even more vigilant and vocal to stop Washington from undermining the legal and administrative pillars that protect our public lands and wildlife and to keep  bulldozers off of intact habitat.  I have been critical of some of the Obama Administration's choices and policies regarding wildlife and wildlands, but there was always give and take within the bounds of existing laws and a relatively strong role for science in how policies were formulated; that probably will not be the case under Trump. Trump and the Republican-controlled Congress probably will slow or reverse progress we have made greenhouse gas emissions , and they will severely weaken or eliminate the legal and bureaucratic institutions that protect our wildlands and wildlife.  Science will be ignored in policy formulation and decision making. Budgets for the folks at the Department of Interior and the Env...

Mount Charleston blue butterfly finally received Federal protection. Photo by Corey Kallstrom, USFWS The U.S. Fish and Wildlife Service listed the Mount Charleston blue butterfly as endangered in September, which should result in more resources to protect this species from vanishing.  The Mt. Charleston blue butterfly is only known to occur in the higher reaches of the Spring Mountains in Nevada, west and northwest of Las Vegas.  The butterfly's population is likely declining, although information gaps preclude us from quantifying its population trends.  The species is believed to be extirpated from six of 16 locations that it has been known to inhabit, and it is only "presumed" to occupy eight of the 10 other locations.  In other words, it may exist in 10 relatively confined locations throughout the mountains, but for eight of those locations it probably has only a tentative existence, at best. The butterfly faces a threat from climate change - more extr...

The petition filed by Basin and Range Watch asking the California Energy Commission (CEC) to reconsider its decision on the BrightSource Energy Ivanpah Solar power project raises new information regarding the potential impact of the solar project on the survivability of desert tortoises.  The CEC approved the project earlier this month based on the assumption that a translocation plan and mitigation funds could offset the likely loss of endangered desert tortoises.  Such mitigation funds were designated for the purchase of land elsewhere in the Mojave Desert to be set aside for tortoise conservation. Genetically Significant Tortoise Population In Decline The Basin and Range Watch petition highlights new information from the Bureau of Land Management's (BLM) biological opinion for another proposed project in the Ivanpah Valley that charactierized the tortoise population in the area -- identified as the Northeastern Mojave Recovery Unit--as the least abundant of all of the t...

The Department of Interior is currently considering a petition by Defenders of Wildlife to list the Mohave Ground Squirrel as an endangered species.  The Mohave Ground Squirrel--whose range spans portions of the western and north-western Mojave Desert--is currently listed as a threatened species under the California Endangered Species Act, but it is not recognized under the Federal Endangered Species Act. I have to take this opportunity to correct mistaken references to the Mohave Ground Squirrel (MGS; alternatively: Mojave Ground Squirrel) on this blog as an "endangered species," even though it has not technically been listed as such under Federal authorities.  The U.S. Fish and Wildlife Service (USFWS)--part of the Department of the Interior--has deemed the petition contains substantial information indicating that listing the MGS as an endangered species may be warranted.     According to the Federal Register (April 27, 2010; Vol 75, Number 80), the USFWS ...
