New research by the University of California suggests we should take a harder look at the potential carbon sequestration capacity of America's deserts.  According to the study, disturbing approximately 11 square miles of desert habitat could release 6,000 metric tons of carbon per year.  That is roughly the equivalent of putting a fleet of 5,300 SUVs on the road, each traveling 120 miles per month.  Desert plants and soil organisms take in and store tons of carbon each year.   When the desert habitat is destroyed, not only does it lose its ability to capture and store carbon, but carbon locked into the soils is likely to be released. According to the study: When desert plants grow, they absorb carbon dioxide (CO2). The carbons (C), as sugars, move into the roots and soil organisms.  Carbon dioxide is respired back into the soil, part of which reacts with calcium (Ca) in the soil to form calcium carbonate.  This is how our deserts sequester large amounts of C and thus function to r

In late February, the Department of Interior reversed its longstanding position in favor of a landfill just outside of Joshua Tree National Park.  For 24 years the Department of Interior supported legal efforts by a company to establish the world's largest landfill just outside of Joshua Tree National Park, where several square miles of canyons would have been filled with 20,000 tons of garbage each day.  The trash, and 24 hour dumping operations would have brought air pollution and subsidized predators that threaten the protected ecosystems that provide peace to many visitors each year.  Over 1.4 million Americans visited Joshua Tree National Park last year, and they came to see beautiful desert vistas, wildlife, and wildflowers, not trash. The efforts to reverse Department of Interior's position were spearheaded by two citizens concerned about misguided policy in California's deserts--Donna and Larry Charpied.  At issue is the landfill company's proposed land sw

I just finished reading A State of Change: Forgotten Landscapes of California by Laura Cunningham.  The author uses her experience as a biologist and artist to reconstruct ecosystems and interactions of California's past using what we know of nature today.  You do not need to be a biologist to appreciate this experience. The book will take you to California's shoreline, oak savannas,  a pristine Delta ecosystem, and deserts, allowing you to observe the interactions among plant and wildlife as it existed in the past.  But this is not just a history book, either.  The author uses her field work observing relict or remaining populations of natural life to reconstruct the past and explain how these landscapes continue to evolve today.  For example, she vividly describes and sketches the majestic California condor and how it behaves with other birds based on hours of her own studies, and recounts her observation of elk herds being stalked by wolves in Yellowstone, where the two spe

Basin and Range Watch posted a review of the proposed desert tortoise habitat mitigation plan being considered by BrightSource Energy LLC.  The company's Ivanpah Solar Energy Generating System is being built on 5.6 square miles of public land, and has already displaced as many as 50 endangered desert tortoises.   As part of it's agreement allowing the company to bulldoze and operate on public land, the company must purchase several thousand acres of privately held desert as mitigation -- the land must serve as good quality desert tortoise habitat and habitat for other special status species affected by the massive solar project. The mitigation land under consideration near the Castle Peaks in the northeastern Mojave Desert is mostly at an elevation higher than 4,000 feet, which is above the average range of the desert tortoise.  The proposed site also does not host many of the rare plants that will be destroyed by the Ivanpah solar project Desert experts have raised seri

An update on the " Friends of Jawbone Canyon " website highlights recent route closures as a result of illegal off-highway vehicle use causing damage to private property and areas of critical environmental concern.  Jawbone Canyon is a checkerboard of public and private land on the western edge of the Mojave Desert, just northeast of Tehachapi and southwest of Ridgecrest.  Some of the public land is designated as protected under the Jawbone-Butterbredt Area of Critical Environmental Concern (ACEC). In partnership with private landowners and the Bureau of Land Management (BLM), dozens of miles of OHV routes were opened to the public to enjoy the natural splendor of the area.  An unlawful few, however, began to create new routes, irreparably harming undisturbed land, natural springs, and even cutting private fences.  Some routes have been closed as Friend of Jawbone (FOJ) Canyon works in partnership with Kern County and the BLM to restore damaged lands. There is such thing

The Twentynine Palms Marine Base released a draft Environmental Impact Statement (draft EIS) for its proposed expansion, which would put over 146,000 acres of the Johnson Valley Off-Highway Vehicle (OHV) area under military control for live-fire exercises.  The military has reportedly met with OHV groups to work out arrangements that give OHV users access to part of the exercise area when it is not being used by the military.  As a result, the Marines' preferred alternative would let OHV users access a portion of the area during 10 months out of the year. The Johnson OHV area is one of the largest in the Mojave Desert, and draws thousands of OHV enthusiasts each year.  OHV use takes a heavy toll on the viability of desert habitat, so much of the area has already been degraded by years of intense OHV use.  However, desert plant and wildlife would still be impacted by the heavy military use of the area, and the Marines expect that anywhere from 121 to 189 adult desert tortoises co

The Federal government is currently reviewing a broad policy shift that could encourage solar energy development on thousands of square miles of pristine public land in America's deserts, according to its Draft Programmatic Environmental Impact Statement ( Draft EIS ).  Unfortunately, the new policy fails to consider a much better alternative, which is to encourage solar energy development on rooftops and on already-disturbed lands.  After a summary of the policy's potential impacts, you can read below to learn how to submit public comments on the policy as a concerned citizen, and urge a smarter approach . Summary of the Policy : The Departments of Interior and Energy are jointly reviewing three alternative policies for permitting solar energy on public land.   Each alternative makes a different amount of public land available to energy companies, but the government estimates that companies will use 214,000 acres (334 square miles) within 20 years.
