The official catalogue assigns CC0 to Beskyttede naturtyper and lists both this SHP download and the dai:bes_naturtyper WFS layer. The registration is indicative and not exhaustive. Actual conditions determine whether an area is covered by §3; contact the municipality to clarify uncertainty. Missing registration does not mean an area is unprotected. This layer excludes protected watercourses and does not assess ecological condition. The public source export also includes draft, proposed and cancelled registrations.
