You got informed by different users in different countries that your note is not very helpfull for different reasons.
a) it is very generic, which areas should be added
b) just one note per country does not help where to add what
c) it is unclear if the source you provided is compatible with OSM, nothing clearly stated on https://portal.discomap.eea.europa.eu/arcgis/home/item.html?id=81d5517768d24f9f90c8c3f710051392 but some restrictions, so probably not a source we can use.
I will now close your notes in the different countries and ask you to start a discussion in the forum instead, as proposed by several people.
