Elements with two CDDA id

I'm finding elements in Spain with 2 CDDA id's, for example Río Guadalquivir -Tramo medio (Q107711286). I didn't checked if this happens with other countries data. Am I missing something obvious or maybe the property restriction should be modified? —Ismael Olea (talk) 16:54, 14 August 2021 (UTC)

In this case, seems its mixing the Natura2000 site and the national site. CDDA 555588872 is listed as national site, whereas ES6130015 (in WDPA 555588872) is the Natura2000 one. At least in Germany there's often a national protected area with similar (or sometimes exactly the same) boundaries to the Natura2000 site, but since both are different legal constructs they should have different items. Oddly, in WDPA 555588872 is listed as Natura2000, but unlike other Natura sites it has a IUCN category. Ahoerstemeier (talk) 21:52, 14 August 2021 (UTC)
