About CIRCLE: The Centre for the Integration of Research, Conservation and Learning is a collaborative initiative between the University of York (a Russell Group University and top 5 for Environmental Science in the UK) and the UK’s most visited zoo, Flamingo Land (Malton, North Yorkshire). The aim of CIRCLE is to carry out ground-breaking research that will contribute to the conservation of wild animals and places, and to disseminate the information in a manner that is accessible, interesting and fun.

 

About Flamingo Land: The zoo at Flamingo Land is part of a global network of zoos and aquariums working together to manage the captive population of threatened animals, to educate visitors on biodiversity conservation and to raise funds for conservation causes. Included among the 130 animal species at Flamingo Land are several animals on the European Endangered Species Program.
