Approximately 200 different animal species reside in the Zoo, and there are almost a 1000 different plant species. Protecting endangered species is a heartfelt matter for the zoo. The zoos in Europe form a network which works to preserve a number of species. Zoos are often the last refuge for many endangered species.
