Some of the bedrock is made up of metabasite, which is a more fertile type of rock than gneiss and granite.
It sticks up above the surface in certain places, including Lilla Lövö. Under the Björnekullakärret fen there is a layer of limestone, and the lime is disseminated into the fen by groundwater, providing the preconditions that enable lime-dependent plants to live there.
