Other Information

Prior to joining the BTO in November 2015, Teresa worked in Local Environmental Records Centres for several years and sat on the Boards of the Association of Local Environmental Records Centres and the National Biodiversity Network. She is interested in engaging people in recording and monitoring their local wildlife and fostering cross-taxa collaboration between wildlife organisations and groups; and in making better and more extensive use of biodiversity recording and monitoring data for policy, research and conservation at all scales. She is a keen but novice naturalist and record moths and other invertebrates as well as enjoying birding.

Teresa sits on the Strategic Working Group of the African-Eurasian Waterbird Monitoring Partnership.
