Tara McHugh, Director

ARS’s Pacific West Area (PWA) delivers innovative research-based solutions to solve problems of importance to U.S. agriculture. Our programs ensure high agricultural productivity, good nutrition, prosperous rural and national economies, and healthy agroecosystems. The Area is composed of 49 research units at 21 locations in 8 states.

Our diverse research portfolio includes ecologically friendly bioproducts, food processing, crop health and productivity, natural resources conservation, rangeland health, crop germplasm preservation, animal health, and human nutrition programs. Our relationships with stakeholders are paramount and ensure that the benefits of our research are realized by American agriculture and associated industries.
