Co-ordination and development of activities relating to species conservation assessments, in particular the application of the IUCN Red List categories and criteria.

The central node for species conservation assessment activity at Kew. Role includes: the development of a database and web infrastructure for assessment auditing/dissemination (CATS), the provision of training protocols for assessment activities and the development of tools (such as GeoCAT) for automated conservation assessments. In addition, the role includes the development of methodologies to improve the quality of and increase output of conservation assessments from Kew. This contributes substantially to the delivery of the Breathing Planet Programme target 2 (BPP 2) - mapping and prioritising and the Key Performance Indicator (KPI) 3 target. Additional interests include the application of GIS methods for Red Listing and conservation, use of the Red List as a barometer for biodiversity (e.g. Sampled Red List Index), the use of electronic devices for data capture in the field, large scale digitisation, georeferencing and web mapping tools.
