Skage Gård is a typical West coast farm. Its total area is 30 ha, with 23 ha of forest and 7 ha of fields (including 60 ha with christmas trees and 0,5 ha of greenery). The production of christmas trees started 35 years ago. Christmas tree sales make up 60-65 % of the farms income, and this percentage is expected to increase. Between 3,000 and 5,000 trees are planted each year and there are approximately 55,000 trees now in production. Most of these must be formed and trimmed

This paper presents the results of a bumblebee mark-reobservation study conducted in a fragmented agricultural landscape, where bumblebee resources (forage, and probably also nest sites) exist mainly on scattered remnants of semi-natural habitat. The results show that reobservations of bumblebees marked while foraging were numerous and in general at short distances (less than 50 m) from where they were marked. In contrast, when bumblebees were marked at the nest, the numbers of reobservations were very low, even though monitoring of nest traffic showed the nest to be very active during reobservation walks. The results indicate that bumblebees do not necessarily forage close to their nest, and that caution is needed if foraging area and nest location are based solely on the observation of foragers
