9 tips for preserving biodiversity in Switzerland

Every flower counts

It’s very simple: every flower counts. So if you have a little corner of nature somewhere around your home, plant some flowers!

Swiss plants

Although exotic plants are sometimes pleasing to the eye, they generally add nothing to the local nature. To preserve global biodiversity, we must therefore encourage native plants everywhere. They, and they alone, constitute the habitat of Swiss wildlife.

Be careful, however, not to demonize plants from elsewhere. Some make it possible to extend the flowering season, constitute a food base for specific insects and are more compatible with new climatic conditions.

The importance of water

Whether ponds, pools, natural pools or swamps, all provide habitat for amphibians, dragonflies and many other animals.

Be careful, however: Since the tiger mosquito has spread to certain areas, it is best to avoid very small bodies of water by turning over flower saucers, buckets and the like.

Do not clean

Good news: you can leave your garden alone. Enough to save yourself a lot of work and at the same time take care of biodiversity. Dead wood can indeed be used for nesting. It also contains food and provides shelter for many species.

Piles of branches, logs, stumps and hedges of dead wood will therefore make your garden a paradise of biodiversity.

Helping birds and other animals

Thanks to nest boxes and insect hotels, we can give flying wildlife a boost. But this is not the only way.

Some insects nest in pine cones, others in wood cavities. Furthermore, wild bees sometimes use snail shells, old bramble stems or dig in sandy soil. There are many opportunities to help one of the 600 species of wild bees or insects.

Stone piles as habitat

Piles of stones or dry stone walls are used by lizards to sunbathe. Other animals use them as hiding places or to spend the winter.

Let’s free the ground

It goes without saying that asphalt and concrete don’t do much for biodiversity. But by focusing on patches of grass or paving stones for your terrace or parking lot, you will make a gesture for nature.

Room for pioneers

Ruderal surfaces are also easy-to-maintain havens of diversity. These are areas of gravel or sand well exposed to light and sparse with vegetation. Many pioneer plants and insects find refuge there. And here again, the rule remains the same: little effort required for a guaranteed effect.

A balcony is enough

The more biomass there is, the more insects there are. A balcony can therefore also be used to shelter living organisms. Because by combining these few square meters with the neighborhood balconies, with the street trees and with the parks, we ultimately obtain a large mosaic where countless animals and insects can settle.

And if you don’t have a balcony: why not install native plants on a windowsill? We repeat, there is no small gesture for biodiversity.
