Since fall 2022, ÖKOPROFIT companies have been working with the environmental agency to increase biodiversity on an urban site. Since then, various activities have contributed to the enhancement of the Käsbach site. The measures implemented range from the removal of neophytes and the cutting back of brambles to the installation of nesting boxes and the creation of new habitats, tree planting and the construction of insect hotels. The insect hotels were assembled by the companies together with the Michel carpentry workshop.
