The vast bog in Store Mosse National Park covers over ten thousand hectares, including outside the national park. The bog is home to many species.

Peat moss, hare's-tail cottongrass and stunted pine

Out on the raised bog, three different species of sundew, a carnivorous plant, thrive (great sundew, spoonleaf sundew and round-leaved sundew) together with over 20 species of peat moss (Sphagnum). Crow'berry, heather, hare's-tail cottongrass and stunted pine give the raised bog its character. On the edges of the bog, bog-myrtle, marsh rosemary and cranberries grow.

To the south lies the limestone-rich Björnekullakärret, and there grow, for example, bog star, cotton deergrass, marsh orchid, helleborine, chalk fragrant orchid, butterwort and broad-leaved bog-cotton, which are typical rich fen species.

The storms changed the flora

Lilla Lövö used to have lush spruce forests until the storms Per and Gudrun felled most of it in 2005–2007. There is a lot of dead wood here in all dimensions, which makes it a good place for various polypores.

After the storm, the European spruce bark beetle killed many of the remaining spruces. Then came the black woodpecker and other woodpeckers and put a stop to the spruce bark beetles. That is why there are still living spruces left on Lilla Lövö.
