Diana is responsible for The IUCN Red List of Oaks initiative at the Morton Arboretum. The goal of this program is to assess the threat level of oaks around the word. Oak-dominated ecosystems all over the world are disappearing, and many species are threatened with extinction. Less than half of the world’s roughly 425 oak species have been evaluated for the IUCN Red List of Threatened Species, the most comprehensive and widely accepted process for evaluating the global threat status of plant and animal species. Diana compiles biological, ecological, and demographic information on the worlds oak trees in order to evaluate their conservation status. She works with the IUCN/SSC Global Tree Specialist group to prioritize Oak species for ex situ conservation collections and for potential protection under policy measures.
