In Limburg this year a record number of eagle owls has been found. During an investigation by ARK Nature Development already fourteen territories of these spectacular owls have been discovered. In 1997, the eagle owl nested for the first time in a limestone quarry near Maastricht. The numbers are growing and the eagle owls are also expanding into woods and sand quarries scattered throughout the province of Limburg.
Industry must act now to safeguard biodiversity threatened by limestone quarrying, say NGOs: here.
