Summary

Abstract
The Beefarm project has developed a cost-effective method investigating the availability of food nesting and hibernation resources for wild bees on organic farms. The method is based on two hypotheses: 1) dominant bee forage wild plants are similar among farms; 2) bee forage plants are located in few easily identifiable habitats.
To evaluate these hypotheses additional botanical analyses were carried out in habitats not included in the BeeFarm survey. In addition a synthesis on food preferences of different types of bees was made.
This project confirms the hypothesis of a high degree of homogeneity among dominant plant species between farms. The restriction of major food resources to few habitats was not shown however a high degree of similarity of distribution of plants among farms was indicated.
Furthermore Bumblebees and solitary bees were found to have a considerable level of shared preferences in terms of forage plant species. Consequently establishing resource availability for both groups jointly is considered suitable.
