Over a career spanning forty-two years, he served in various government departments, focusing on the predatory mammals of the American West, including wolves, coyotes, cougars, and bobcats. Young's research contributed to a deeper understanding of these species and their roles in the ecosystem, advocating for their conservation and management in the face of changing environmental conditions and human encroachment. In addition to his scientific contributions, Young was a prolific author, sharing his insights and findings through numerous publications. His notable works include studies that highlighted the ecological importance of predators and the need for sustainable wildlife practices. Young's legacy endures in the field of ecology, where his pioneering efforts laid the groundwork for modern wildlife management strategies and conservation policies, making him a key figure in the history of American environmental science.
