Modern zoos consider themselves to be nature conservation centres and have formulated a common worldwide conservation strategy, which is backed up by the world conservation union IUCN. The Zurich Zoo's strategy verbalized in 1992 draws on this strategy; this makes the Zurich Zoo one of the most modern zoos of the world. Its core piece is the Masoala Rainforest. An appealing nature experience with animals and plants as centre stage is meant to conquer the hearts of the visitors. The display of these treasures and wonders of nature are to fascinate young and old; they are to be informed and encouraged to make a personal contribution to conservation.

The zoo shows you the causes of the disappearance of forests, but also projects that help conserve the forests. Through direct contributions, the Masoala Rainforest at the zoo is bearing one third of the costs that are necessary to finance the park in the long run. The promotion of ecotourism shall bring money into the region; thus the park also acquires an economic value. Sponsored by the Wildlife Conservation Society and the Malagasy national park authorities ANGAP, an important part of the whole enterprise are small development projects in favour of the surrounding villages, which in return must assume more responsibilities for the parc.
