Wyoming - Pinedale Anticline and Jonah

State: Wyoming
Region: Upper Green River Valley

EcoFlight’s mission in this area is to protect and preserve the clear air, clean water and abundant wildlife that define the extraordinary Upper Green River Valley in Western Wyoming.  There is substantial energy development on BLM lands here. Gas reserves in the Pinedale Anticline and Jonah fields have proven to be some of the most productive and lucrative in the nation. While development brings increased revenue to the state and solidifies Wyoming’s role as a key energy provider to the country, there is a downside. Air quality is markedly poorer than it was before large-scale gas development appeared. In March 2011, pollution from natural gas drilling in the Upper Green River Basin in western Wyoming triggered levels of ground-level ozone, the main ingredient in smog, worse than those recorded in Los Angeles, one of the smoggiest cities in the U.S.

Documented impacts to wildlife populations, particularly sage-grouse and mule deer, are well known. The oil and gas boom is also affecting the quality of life in small towns like Pinedale, causing spikes in the housing market and adversely affecting tourism, the state’s second largest industry.

EcoFlight will work with its partners to ensure that energy development is balanced and responsible and with the least impact on our valuable natural resources.
