The revival of the housing market has renewed a perennial threat to desert wildlands - urban sprawl.  Developers are considering plans for large new suburban developments across the southwest, years after such large developments mostly stalled when the housing industry began to crash in 2006.  At a time when most of our efforts have been focused on protecting public lands from industrial-scale development, urban sprawl underscores the need for local efforts to protect open space under private ownership. The NASA video above shows the extent of Las Vegas' urban sprawl since 1972. Along the Mojave River in California, the Tapestry project could result in the destruction of nearly 9 square miles of juniper woodland and chaparral habitat in the Summit Valley to make way for at least 16,196 homes.  The area is popular for hiking, jogging, and mountain bike riding.  During environmental surveys, biologists observed or detected western pond turtles, coastal horned lizards, bobc

The Department of Interior on Tuesday released the final environmental impact statement for the first phase of the Desert Renewable Energy Conservation Plan ( DRECP ), which significantly alters the land use planning for public lands administered by Interior in the California desert.  Although the final version expands conservation designations that were popular in the draft DRECP,  it also seems to introduce uncertainty for nearly 802,000 acres of "unallocated" lands that are neither part of conservation nor a development designation.  The public has 30 days to submit any concerns regarding the final draft before it is made official by a Record of Decision. Subtle Change Has Significant Impacts If you looked at the draft DRECP released for public comment late last year you probably paid attention to where large-scale energy development would be allowed, and where it would not.  After all, it is the added threat posed by utility-scale energy development to public lands

Solar power tower developers have chided critical press coverage of their massive facilities as letting perfect be the enemy of good.  But we have learned enough about this technology to know that power tower projects do not even qualify as "good" clean energy projects.  Far superior alternatives exist in terms of life-cycle carbon emissions and sustainable siting. Solar power towers have earned a bad reputation, and their developers are desperate to restore the green halo that they enjoyed a few years ago.  NRG - the current owner of the Ivanpah Solar project in California - and Solar Reserve - owner of the Crescent Dunes project in Nevada - have long been on the defensive with inaccurate and misleading public relations efforts.  But they have stepped up their PR efforts after new reports on their natural gas use and impacts on wildlife. Although developers promise to eventually deliver energy storage benefits, other technologies allow us to do so without burning birds
