Bergkiefer
Nordby Heath (Danish: "Nordby Hede") is a 6 km2 large heath, largely covered in "erica". It was protected, along with Stavns Fjord, in 1981. Up to a quarter of the heath is covered in the invasive moss "campylopus introflexus", which suffocates the native "erica". Other invasive species threatening the heath are "rosa rugosa" and "Pinus mugo". Cattle has been grazing on the heath since 1998.
