Tree hollow habitat

Successfully realized


The non-profit organization FREETHEBEES carves out tree hollows in forests to provide nesting sites for wild honeybees and a range of other endangered insects that dwell in the cavities of trees.

The organization’s dedicated volunteers have learned how to carve out tree hollows (called a Zeidlerhöhle in German) into living trees. These cavities serve as a shelter for many different species in need of protection, such as wild honeybees, as well as a place for these species to feed and reproduce.

“Thanks to the dedicated efforts of UBS Helpetica volunteers to carve out tree hollows in the wild in Elm, some balance has been restored to the lives of wild honeybees, as well as the forest ecosystem,” says Yvonne Isaac-Kesseli, strategy officer at FREETHEBEES.


Our project partners

The non-profit organization FREETHEBEES raises awareness of key aspects of the fight against bee mortality and promotes ways to combat it from an independent, interdisciplinary perspective. It does so through innovative measures such as restoring bee habitats, creating incentive schemes and further training in sustainable beekeeping for beekeepers and people interested in nature, as well as providing environmental education for young people and children.
