Site details


Site description: The area is situated in the Demer river valley, west and east of the town of Diest. It comprises a rich variety of former river arms, peat ponds, marshes, reedbeds, sedge-fields, humid grasslands and alluvial forests, including heathland relicts on the sandy hills bordering the valley.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
