The Frankfurt Zoological Society

FZS is an international conservation organisation based in Frankfurt in Germany. Founded by Prof. Bernhard Grzimek, FZS is committed to preserving wildlands and biological diversity in the last remaining wilderness areas on the planet.

The Serengeti National Park in Tanzania was the starting point of the Frankfurt Zoological Society's conservation efforts. At the end of the 1950s Bernhard Grzimek launched what has since become a comprehensive programme consisting of some 30 projects dedicated to the protection of outstanding wilderness areas and national parks in 18 countries. The conservation focus of all FZS projects is on protecting wilderness areas and preserving biodiversity. All FZS programmes are oriented towards these two criteria.


FZS is active in biodiversity-rich areas in central and eastern Europe, in east Africa, in central South America and in south-east Asia. In terms of habitats the main focus is on the great savanna, forest, wetland and mountain areas. The main emphasis in Europe is on wilderness development in Germany and the conservation of pristine habitats in the Balkan states, Ukraine, Belarus and Kazakhstan. Our project countries in east Africa are: Tanzania, DR Congo, Zambia, Zimbabwe and Ethiopia. The focus in South America is on our major programme in Peru and our new project in Guyana. The project areas in south-east Asia are Sumatra and Vietnam.

Society & Foundation


Zoologische Gesellschaft Frankfurt von 1858 e.V. is a registered non-profit-making society. Our work is financed by the contributions from our members, private donations and bequests and endowments from our supporting foundation, Hilfe für die bedrohte Tierwelt. Support for our projects also comes in the form of external funding, for instance from foundations or public funding programmes.


FZS has roughly 350 employees, with almost 30 working at the head office in Frankfurt, and all the others in the different project countries. In addition there are around 40 volunteers working as conservation ambassadors at Frankfurt Zoo, and 30 or 40 volunteers are also currently carrying out environmental education work as part of the Peru Programme.
