Path through a mix forest, Jan Pieter Kok, Terschelling


During the first half of the last century, man planted forests on all of the Dutch Wadden Islands, hoping to end the drifting sand from invading the villages and fields. In addition, wood was needed in the mining industry. Black pine (Pin de Corse) was planted the most, a rapidly growing tree that can survive in nutrient-poor sand. However on the Wadden Islands, even this species of tree did not grow well. Nor were many trees harvested for mining. Later on, the forests became important for recreational purposes. In the meantime, most forests have been converted into mixed forests. Many of the original (coniferous) forests were planted on the dunes but because these trees do not generally lose their needles, they continue to extract a lot of groundwater in the winter. Deciduous trees lose their leaves and therefore extract less water out of the dunes. By planting a mixed forest, less water is extracted and the dunes do not dehydrate as quickly.
