Janzen in 2009 }}

Daniel Hunt Janzen (born January 18, 1939) is an American evolutionary ecologist, and conservationist. He divides his time between his professorship in biology at the University of Pennsylvania , where he has been since 1976, and his research and field work in Costa Rica, where he is an ''ad honorem'' (without remuneration) technical advisor for two long-term and long-range projects, which he conceived and initiated in the early 1970s: Area de Conservación Guanacaste, one of the oldest, largest and most successful habitat restoration project in the world, 1.430 km², located just south of the Costa Rica-Nicaragua border, between the Pacific Ocean and the Cordillera de Tilaran; and the Instituto Nacional de Biodiversidad (INBio), a research organisation that has taken the task of inventorying, cataloguing and describing the country's gigantic natural endowment. He has been influential in the creation of a "model" park, the Area de Conservacion Guanacaste in Costa Rica's northern region of Guanacaste. This park exemplifies Dr. Janzen's beliefs about how a park should be run. It is known for being the site of considerable biological research and for forest restoration and community outreach.
