Humankind has taken possession of the planet. Ahead of this progression, most animals have  fled far away from cities and major roads, high up in the mountains or deep in the woods. 60% of wildlife species have disappeared in the last forty years, and biodiversity is in danger. 

But here in Forêt Clochettes, in the heart of the city, the creatures that used to live in the Lausanne area have returned, as evidenced by the calls and the songs that ring out in the bower hedge. Curious passers-by who lean inside do so at their own risk: at the peril of discovering another universe, a strange wild world, and a miniature sanctuary.
