Belgium's Biodiversity is under serious threat as a result of human activities. The main reasons for the decline of biodiversity are the destruction and fragmentation of natural habitats, pollution and eutrophication caused by agricultural and industrial practices, excessive water catchments in some areas, climate change and perturbations linked to leisure and tourism.

2. Resource partitioning among bumble bees.
Species have proboscises of different lengths, enabling them to specialize in the exploitation of plants with different length corollas. Species with similar length proboscises occur at different altitudes (Pyke 1982).
