South Shale Ridge Oil and Gas Leasing

Case Overview

The South Shale Ridge wilderness is home to wildlife and rare plants, and is a popular destination for hikers and hunters. However, the BLM reversed an earlier recommendation to protect the ridge as a Wilderness Study Area and instead leased the vast majority of land for oil and gas drilling.


In August 2007, the Federal District Court in Colorado ruled that the BLM violated the Endangered Species Act and the National Environmental Policy Act when it granted the leases, and ordered the BLM to consider the effect of drilling and development on rare species in the area.
