's-Hertogenbosch sits at the confluence of the Dommel and Aa rivers, where oak, birch, and linden are the main tree pollen sources alongside grass from urban green spaces. Exposure varies between the greener river corridors and the more built-up city centre, while surrounding North Brabant farmland and heathland contribute substantial grass and tree pollen across the historic city.
