Diverse structures create habitats

Supporting small animals at home

The Wildnispark Zurich Foundation is actively committed to increasing biodiversity. The small animal living community on the grounds of the Visitor Centre in Sihlwald is one of these initiatives. Small structures support plants and animals that would otherwise find little habitat. Help us and support native biodiversity in your garden or on your balcony. Even small changes often have a big impact.

 

Reptiles and other small animals depend on small structures. It is crucial that structures and other habitats are interconnected so that they can be colonised by animals.

A few simple basic rules go a long way

Larger structures are generally better, but even small areas can have a big impact. It is important to give preference to native plants and to adapt structures to the needs of certain species. Factors such as sunlight and soil conditions must also be taken into account. Not every location is ideal. In principle, nature should be left to its own devices. It is particularly important not to use fertilisers and pesticides in order to protect natural diversity.

Branch pile

A branch pile is a structure made of branches that can be combined with leaves, stones or sand. Depending on this, different inhabitants move in.

Deadwood

Deadwood provides a valuable and diverse habitat. It serves as a food source and hiding place for numerous animals. A dead tree, whether still standing or lying on the ground, lives on through its inhabitants.

Nesting aids

Nesting aids can help endangered species such as wild bees, birds and bats, which are particularly affected by dwindling habitats, to raise their young. Nesting aids should be stable and protected from the rain. A roofed house wall is particularly suitable for this.

Raised bed

A raised bed can also be used to create a biodiverse area in small spaces such as on the balcony or patio, or if the available space is sealed.

Reptile burrow

A reptile burrow is a composite habitat consisting of piles of stones and branches in a sunny location. It provides hiding places and sunbathing areas for reptiles and amphibians or serves as a place to hibernate.

Ruderal area (dry site)

Ruderal areas are habitats with stony or sandy subsoil that have a mosaic of overgrown and open patches of ground. Ruderal areas are often populated by pioneer plants and ground-nesting insects.
