This module serves as a focal point for students on the Wildlife Health and Conservation MSc Programme. As natural habitats are increasingly affected by human activities, a growing number of species worldwide will require active management to survive. The long-term goals of such management are to secure self-sustaining, healthy and genetically robust populations within natural ecosystems. Zoos have a crucial role to play in the active management of threatened species, offering protection and intensive management of those species in most immediate danger of extinction, and an active role in reintroduction programmes and the conservation of natural populations. This module is taught at Chester Zoo by conservation professionals with internationally leading expertise in the successful management and conservation breeding of threatened species. Students will gain theoretical knowledge and skills necessary to contribute to the management of threatened species, including an understanding of international legislation and policy frameworks. The module combines focus on the conservation of natural populations (in situ- conservation) with the management and conservation breeding of endangered species in zoos (ex-situ- conservation). This combined or ‘One Plan’ approach to conserving endangered species provides a distinctive theme throughout the module. Topics covered include the One Plan Approach to conservation science, zoo facility and husbandry design concepts, monitoring and evaluating animal welfare, managing animal health and disease, population management and genetics, international conservation breeding programmes, reproductive health, contraception, endocrinology, assisted reproductive technologies, and conservation science leadership. The module is taught using active learning methods that include lectures, workshops and student-led discussions. Directed key reading and other learning resources are provided in a virtual learning environment (VLE) that develops digital fluency and encourages assimilation and appraisal of module content. The module is assessed using two assignments that are designed to demonstrate depth of understanding and the ability to apply knowledge to real-world conservation scenarios. For the first assignment, students will produce a five-minute video designed as an opening presentation for a One Plan Approach stakeholder workshop. For the second assignment, students will write a report explaining how they have utilised a professional welfare evaluation tool for a species kept as part of a conservation breeding programme. The report should demonstrate compliance with the Animal Welfare Goal of the World Association of Zoos and Aquariums (WAZA).
