Peter Berulf Johnsen has worked on recovering endangered and threatened fish in the Pacific Northwest for more than eight years. With a master's degree and expertise in Behavioral Ecology and Evolutionary biology, he has a strong understanding about the importance of biological diversity. He also has a background in social and economic development and has recently begun exploring the important connection between human and environmental relationships. In 2010, Peter started The Great Salmon Tour, which illustrates the connection between salmonids and people. He has visited communities in Alaska, California, Bosnia-Herzegovina and Mongolia to document salmon diversity and interview people about their ties to these fish.
