Trees are essential in mountain pastures. They provide shade for livestock, protect the soil from drying out, retain water and help limit erosion. They also create shelter and vantage points for many species. Birds such as the red-backed shrike and the tree pipit depend on these landscapes, where grasslands and wooded areas are interwoven.

With climate warming, periods of drought are becoming more intense. Some trees weaken and disappear, gradually transforming the landscape and the life it supports. Natural regeneration remains challenging, as young shoots are often grazed by livestock or wildlife, and snow can hinder their establishment.

Here in Chli Sattel, young trees have been planted on land made available by committed landowners. The aim is to diversify tree species, particularly by introducing broadleaved trees that are better suited to future climatic conditions.

Areas protected by wooden fences, known as planting islands or exclosures, allow young shoots to grow without being grazed by livestock or wildlife.

This project was made possible thanks to the commitment of the landowners – the Pratley family – and the support of the Gruyere Pays-d’Enhaut Regional Nature Park and Forêt Gruyère.

The Tree Pipit

Once widespread across Switzerland, the tree pipit has become rarer and is now mainly found in mountainous regions. It favours semi-open habitats with grasslands and scattered trees that are rich in insects. Its song, delivered during display flights, resonates above the pastures.
