The forestry department of Terschelling island in the Netherlands reported on 4 July 2017 that rare plants which had been away for decades are now back near Doodemanskisten lake.
They are, eg, pillwort fern and bog pimpernel. These species had disappeared there in the 1950s after the Doodemanskisten environment had deteriorated. A few years ago, conservation measures to improve the situation started.
