Korkeasaari Zoo is one of the most popular leisure destinations in Finland, and every year, it attracts almost half a million visitors of all ages. The zoo is open all year round. The most important mission of Korkeasaari is to conserve biodiversity and each and every one of the visitors supports this work. Korkeasaari is home for nearly two thousand animals representing approximately 160 species.

Korkeasaari conserves biodiversity as part of the network of zoos and conservation organizations. Endangered species are conserved by breeding as genetically diverse populations as possible to ensure the future of the species. Declining populations in the nature can be strengthened with the help of zoo populations, and animals can be reintroduced to areas where they have previously lived. European forest reindeers, Przewalski's wild horses and many other species have been sent from Korkeasaari Zoo to the wild.

The Zoo is managed by a non-profit foundation, called the Foundation of Korkeasaari Zoo (officially Korkeasaaren eläintarhan säätiö).

The European Association of Zoos and Aquaria is the organisation that sets the standard for progressive zoos, aquariums, and other partners across Europe and Western Asia. EAZA makes sure that its member zoos and aquariums achieve and maintain the highest standards of animal care.

Formed in 1992, EAZA’s mission is to facilitate cooperation within the European zoo and aquarium community towards the goals of education, research and conservation. The organization believes that zoos and aquaria have a strong role to play in protecting nature and wildlife both at the institutions and out in the field.

It is estimated that more than 140 million people visit EAZA members each year, equivalent to approximately one in five European citizens.
