As a Green Key certified establishment, biodiversity is important to us. In February 2024, we hung up 20 nesting boxes with two differently sized entry holes for cavity breeders, such as tits, pied flycatchers, sparrows and nuthatches. These provide a peaceful place for the birds to raise their young during the nesting period in spring. Birds need good nesting conditions. According to the Swiss Ornithological Institute, around 40% of Swiss bird species are endangered. With this campaign, we were able to engage socially at the same time, as the nesting boxes were purchased from the Rüttihubelbad social therapy community, which provides work for people requiring additional support. The nesting boxes are exclusively made from solid wood, which usually comes from the community's own forest, gets processed in a resource-friendly way and is not treated with chemicals.
