This dissertation examines the operation of neoliberal environmentality through the instrumentalization of the Greater Sage-grouse (Centrocercus urophasianus) in Wyoming. It treats technological interventions within environmental construction as generating biotic-machinic entanglements termed technonature. I present the formation and operation of the Wyoming Conservation Exchange as a case study of technonatural territorialization connected to global trona and hydrocarbon commodity flows. The theoretical framework elaborates how "the environment" is constructed and governed through tactical instrumental deployments connected to technocratic management allowing economically powerful actors to inscribe their desires within Wyoming's landscape, politics and biota as a function of environmental security related to commodity development. The question motivating this work is "Whose environment is the Environmental Defense Fund defending?"

The Greater Sage-grouse has become an object of U.S. Federal environmental governance since the late 1990's. It has experienced significant population declines due to anthropogenic disturbance and habitat loss through industrial action across its range. Wyoming's Sagebrush Steppe contains 37.5% of the remaining range wide population. The grouse was listed as a candidate species under the 1973 U.S. Endangered Species Act triggering responses from Federal, State, and international wildlife management agencies, as well as environmental non-governmental organizations. Wyoming could lose nearly a quarter of its surface should Federal regulations require the designation of critical sage-grouse habitat. Governor Dave Freudenthal signed Executive Order 2008-2 into law in response to the regulatory threat to Wyoming's hydrocarbon and mineral based economy. The grouse, in response was de-listed as a candidate species in 2015 by the U.S. Fish and Wildlife Service.

EO 2008-2 established the Wyoming Core Area Strategy as a statewide conservation umbrella and laid the framework for a habitat mitigation economy allowing industrial activity to continue within sage-grouse habitat. This incentivized the Environmental Defense Fund (EDF) to test a market-based instrument – a habitat exchange – within Wyoming. The Greater Sage-grouse is a test species as it is highly sensitive to changes in its environment and this dissertation examines how the habitat mitigation economy advanced by EDF is drawing the grouse into global commodity networks as a territorialization process for global flows of hydrocarbons and minerals. At stake is the ability to write the history of the species, land, and the global environment as EDF develops conservation technologies prioritizing flows critical to the hydrocarbon environment through the technology of the Wyoming Conservation Exchange.
