(See USGS Data Series DS-437) The purpose of this map service is to explore current oil and gas energy development in the area encompassing the Wyoming Landscape Conservation Initiative (WLCI). The WLCI is a long-term science-based effort to ensure southwestern Wyoming's wildlife and habitat remain viable in areas facing development pressure. Wyoming encompasses some of the highest quality wildlife habitats in the Intermountain West. At the same time, this region is an important source of natural gas. Using Geographic Information System (GIS) technology, energy data pertinent to the conservation decision-making process have been assembled to illustrate the temporal evolution of oil and gas production in the Greater Green River Basin over the last century. In addition to historical data, estimates of undiscovered oil and gas are included from the 2002 USGS National Assessment of Oil and Gas in the Southwestern Wyoming Province. This report is meant to facilitate integrating existing data with new knowledge
