The Tree Kangaroo Conservation Program was founded at the Woodland Park Zoo (Seattle, WA, USA) in 1996. It began as the first wild study of the endangered Matschie’s tree kangaroo in Papua New Guinea and grew into a community conservation, development, and health effort. It now protects roughly 180,000 acres of cloud forest in the YUS Conservation Area while supporting the 15,000-plus people who live there. Framed in terms of the ethics and science of one health, the program recognizes that people depend directly on the forest, so human, animal, and environmental health are inseparable.

This series on One Health Ethics is co-hosted with the Society for Conservation Biology North America.  ...
