Daniel H. Janzen and his wife and research partner, Winifred Hallwachs, have dedicated their lives to studying, restoring and protecting tropical forests. Their groundbreaking work pioneered a new era in ecological restoration, most notably in the creation of the Area de Conservacion Guanacaste in northwestern Costa Rica. At 410,000 acres, this reserve is one of the largest protected areas in Central America and contains four distinct ecosystems. Through stunning images, Janzen will share his great passion for conserving the intricate caterpillars and breathtaking butterflies that live in the reserve. By studying these insects in their natural habitat, Janzen and Hallwachs have discovered hundreds of new species, including Porphyrogenes peterwegei, a butterfly they named after fellow conservationist and West Michigan philanthropist Peter Wege, for his friendship and ardent support of their work. Janzen will conclude his lecture with poignant perspectives on the future of biodiversity conservation, the role of social integration with complex tropical wildlands and both the opportunities and challenges of managing a globally significant biological hotspot.
