Ben manages the Indicators and Assessments Unit at the Institute of Zoology, Zoological Society of London. This includes four major projects aimed at measuring the status and trends in biodiversity in order to improve conservation science and inform progress towards the CBD 2010 Target. Ben has experience primarily with global-level Red Listing, but has also worked on both the Mongolian Red List of Mammals and of Fishes.
