In 2013, following an invasion of the mountain pine beetle, an insect that attacks Sitka spruce, 30 hectares of forest were felled as a preventive measure. The land cleared was replanted between 2015 and 2016 with 30,000 seedlings: 56% Douglas fir, 28% Scots pine, 6% Laricio pine and 10% hardwoods, hornbeam and beech. These hardwoods are ideal near wetlands, as they acidify the water far less than softwoods.
