  • He divides his time between his professorship in biology at the University of Pennsylvania, where he is the DiMaura Professor of Conservation Biology, and his research and field work in Costa Rica.In Costa Rica, Janzen and his partner Winifred Hallwachs helped to establish the Area de Conservación Guanacaste World Heritage Site, one of the oldest, largest and most successful habitat restoration projects in the world.
  • As of 2019, it consists of 169,000 hectares (420,000 acres), located just south of the Costa Rica-Nicaragua border, between the Pacific Ocean and the Cordillera de Tilaran.
  • The park exemplifies their beliefs about how a park should be run.
  • It is known as a center of biological research, forest restoration and community outreach.Closely related is their work cataloguing the biodiversity of Costa Rica.
  • Through a DNA barcoding initiative with geneticist Paul Hebert, they have registered over 500,000 specimens representing more than 45,000 species from Área de Conservación Guanacaste.
  • This research has led to the identification of cryptic species of near-identical appearance that differ in terms of genetics and ecological niche.
