Penny Langhammer, Ph.D.

Director of Key Biodiversity Areas and Species Assessment

Dr. Penny Langhammer leads the organization’s efforts to identify and promote the conservation of Key Biodiversity Areas. She also oversees the work within GWC to assess species for the IUCN Red List. As co-chair of the IUCN WCPA-SSC Joint Task Force on Biodiversity and Protected Areas, Penny led the development of A Global Standard for the Identification of Key Biodiversity Areas, for which she received the George Rabb Award for Conservation Innovation from the IUCN Species Survival Commission. Penny has a strong interest in amphibian conservation and also serves as Director of Key Biodiversity Areas for the Amphibian Survival Alliance.

Penny maintains active research collaborations with the School of Life Sciences and the Center for Biodiversity Outcomes at Arizona State University, and she co-facilitates the Infectious Disease Working Group for the IUCN Amphibian Specialist Group. Prior to joining Global Wildlife Conservation, she founded the biodiversity consulting firm Terra Consilium and acted as its principal consultant. Penny began her career at Conservation International, working for nearly a decade to support CI programs and partners across the globe in defining science-based outcomes and priorities for conservation.
