Obere Havelniederung (SiteCode: DE3145421) is a Birds Directive Sites (SPA).

It is covered by Natura2000: https://natura2000.eea.europa.eu/?query … ,DE3145421
It is also an IUCN Category V land: https://www.protectedplanet.net/323340

Under the current scheme, it is ambiguous; should it be protect_class=5 because it is IUCN category V? Or should it be protect_class=97 because it is a Natura2000 area? Most areas that are part of Natura2000 will also have an IUCN category. It is ambiguous, and this is just one example of where the protect_class scheme fails.

What other information is needed to describe that area?

The answer here is very easy: The legal background of the Natura 2000 site and the landscape protection area are very different and so we need two separate relations for both sites. This is also needed for linking to Wikidata. If you had a look at the links you might also noticed that size and geometry of both sites are very different, this would be the main reason for not combining them in one relation.
