Pollination and Fruit Farms at Lake Constance

Project summary

In the past years, native wild bee populations declined dramatically, which was accompanied by high mortality rates of bees reflecting the landscape’s imbalance. Intensification of land use (e.g. loss of set-aside land, intensified use of grassland, increase of biomass production) is one major reason for this development. This leads to a greener landscape with less blooming plants. Therefore, forage availability for pollinators declines dramatically during the summer months. In order to close this gap in forage supply Lake Constance Foundation, Obst vom Bodensee Vertriebs GmbH and REWE Group, initiated a project.
Fruit growers around Lake Constance create flowering meadows, plant hedges and put up artificial bee nests for wild bees. These measures improve forage supply during the summer and create new habitats. The project demonstrates how environment and nature conservation in cooperation with the private sector can create measurable profit for nature and business at the same time.

Project results

At the moment, about 25 people are directly involved in the project at the moment. The expert team is composed of fruit cultivation specialists, several regional nature conservation representatives, bee keepers as well as one wild bee expert.
The 11 pilot companies planted more than 10 hectare of flowering meadows with annual and perennial plants. Additionally, more than 20 artificial nests were installed and about 500 metres of hedges were planted. The project was awarded with the REWE sustainability label Pro Planet.
In 2011 next steps will be to involve other fruit farms in the Lake Constance region as well as from other fruit growing regions in Germany.
