Jenny Daltry, Ph.D. F.R.G.S.

Caribbean Alliance Director

    Education

    Ph.D., Tropical Zoology, University of Aberdeen

    B.Sc. Zoology, University of Bristol







    Dr. Jenny Daltry works chiefly on the restoration of island ecosystems and recovery of endangered species. Though perhaps best known for leading programs to save critically threatened reptiles, including Siamese Crocodiles, Antiguan Racers and Union Island Geckos, she has worked on a wide variety of animal and plant taxa in over 30 countries. Prior to joining Global Wildlife Conservation, Dr. Jenny Daltry was Senior Conservation Biologist at Fauna & Flora International and for many years served as director of operations in the Caribbean and Cambodia, where she received a knighthood for her services to conservation.

    Jenny began her career as a volunteer, working in zoos and supporting research and conservation of India’s Andaman and Nicobar Islands. Her doctoral research took her to Southeast Asia, where she studied the ecology of venomous snakes before embarking on biodiversity inventories and working with Indigenous communities to preserve critical habitats and improve livelihoods. Jenny’s interest in ecosystem restoration began in 1995 upon seeing the devastating impacts that non-native rats have on Caribbean biodiversity. Since then, she has led projects to successfully eradicate harmful invasive animals and plants from nearly 30 islands, catalysing the rapid recovery of native species and ecosystems. Jenny is particularly interested in how restoring healthy, functioning ecosystems, both inside and outside of protected areas, can strengthen the resilience of island people and wildlife to climate change.

    Dr. Daltry is a strong believer in responding to locally identified needs and encouraging and enabling local community groups and government agencies to raise funds and run their own custom-designed conservation programs. She is an active member of six IUCN SSC Specialist Groups, an Adventure Ambassador for GREAT Britain and North Ireland campaign, and a National Geographic Emerging Explorer.
