There are eight different species of bats in Rold Skov forest, out of a total of 17 Danish species. The forest is attractive to bats because of the combination of watercourses and lakes in the forest which provide good opportunities for food, and because of the hibernation sites in the Thingbæk limestone mines and numerous hollow trees, woodpecker holes and other places. The houses of the forest are also popular, even the forest supervisor’s Mosskovgård house has a population of the smallest Danish species; the pipistrelle.
The bats can be seen all-year-round in the Thingbæk limestone mines where around 500 bats reside; particularly Daubenton's bats. Otherwise try spending an evening on the bank of the Lindenborg Å stream or one of the forest’s lakes and experience the bats’ amazing hunt for insects above the surface of the water. Our largest species, the great bat, can also be seen just before sunset when it flies out early to hunt.
All the species of bats hibernate from October to April. Some species prefer hollow trees, whereas a number of species seek old limestone mines or buildings. In Rold Skov forest, bats receive special help as a couple of ammunition bunkers from the Cold War were especially designed for bats.
The flying mice of Rold Skov forest include: Serotines, noctules, long-eared bats, pond bats, Daubenton's bats, natter’s bats, pipistrelles and Brandt’s bats.
