In his 1998 book Consilience, E.O. Wilson set forth the idea that integrating knowledge and insights from across the spectrum of human study -- the humanities, social science, and natural sciences -- is the key to solving complex environmental and social problems. Experiments in Consilience tells the unique story of a pathbreaking effort to apply this theoretical construct in a real-world setting. The book describes the work of the Biodiversity Research Network, a team of experts from the United States and Canada brought together to build interdisciplinary connections and stimulate an exchange of expertise. Team members sought to understand the ecology and population dynamics of key species in particular ecosystems, to understand the impact of human populations on those species and ecosystems, and to develop tools and processes for involving a greater variety of stakeholders in conservation efforts. In order to keep the experiment grounded, the network focused on a single type of conservation planning workshop run by a single organization -- the Population and Habitat Viability Assessment Workshop (PHVA) of the IUCN-sponsored Conservation Breeding Specialist Group (CBSG).
