Current projects of the association
«Chräbs im Chräbsächerli»
Crayfish play an important role in the water ecosystem as «nature's cleaning agents» and are to be reintroduced to the Sihlwald.
Crayfish once populated the streams of the Sihlwald, but today they are no longer found there. Functioning ecosystems are crucial for biodiversity and adaptation to climate change. Crayfish are part of this. Studies have now shown that some streams in the Sihlwald offer optimal living conditions for crayfish.
The project
Wildnispark Zurich is planning to reintroduce crayfish to the Sihlwald in collaboration with «Lebensgemeinschaft Wasser Schweiz». In addition, interactive exhibition elements are planned in the aquarium on the grounds of the Visitor Centre. These are intended to inform children and adults about the native aquatic inhabitants and raise their awareness of their protection.
The Förderverein Wildnispark Zurich is supporting this project. Various member events are planned as part of the project.

Small animal commune
Who is scampering between the stones? Who lives in the pile of branches? The Förderverein Wildnispark Zurich is committed to this project.
On the grounds of the visitor centre in Sihlwald, visitors will find several experience stations on the topic of biodiversity under the motto «small animal commune». In a confined space, visitors can experience what is good for nature and how the diverse interplay between native plants and animals works.
The project
The various exhibition elements are getting old and need to be renewed. In addition, the Wildnispark Zurich Foundation would like to take the opportunity to integrate more habitats into the concept. At the experience stations, the focus will be more on suggestions on how visitors can transform their own garden or balcony into a small nature paradise with simple tips: small changes with a big effect for biodiversity.
Donation information
Donations can be deducted from taxes. Your donation will go to the Förderverein Wildnispark Zurich, which will use the amount exclusively for this project.

Wildnispark Zurich
It doesn't take much ... but many! An association for everyone who is enthusiastic about the Wildnispark Zurich.
The Förderverein supports the Wildnispark Zurich. It is committed to the Langenberg Wildlife Park and the Sihlwald Nature Discovery Park. The wild animals, the nature forest and you as a member benefit from the association:
- The association invites you to events and excursions
- The magazine «Wildnis» is sent to you by post (German only)
- Every year you receive free family admission to the Nature Museum in Sihlwald (worth CHF 20)
The Förderverein regularly supports special projects. In the past, it has contributed significantly to the expansion of several animal enclosures and to making them more natural. Donations to such projects can be deducted from your taxes.
Our history
The Förderverein was founded in 1993 as the «Society for the Promotion of the Langenberg Wildlifepark». At that time, it belonged solely to the city of Zurich and was operated by Grün Stadt Zürich. The members of the Förderverein ran the kiosk at Langenberg Wildlife Park as a voluntary organisation. In recent years, the funds generated have been used to help finance projects such as the Müsli-Hüsli the wild boar enclosure and the new animal information boards.
