Species with doubtful degree of establishment should not have doubtdul occurrenceStatus

Some of your doubtful species are certainly present e.g. Pinus sylvestris, Narcissus pseudonarcissus, so perhaps it is doubtful that they are naturalized. For P. sylvestris the checklist says it is doubtful only for Brussels. He must mean it is doubtfully naturalized, but cause I'm 100% sure it is present.

Picea abies, Pinus rigida and Pinus pinaster are probably similar cases. They are planted, but it is doubtful if they are escaping.

For N. pseudonarcissus the checklist is only refering to Narcissus pseudonarcissus L. subsp. major . Not N. pseudonarcissus in general. It is an important distinction as N. pseudonarcissus is a native species, but not this subspecies.

The rest are probably genuinely doubtful species. That is they are doubtfully present.

@LienReyserhove can you ask Filip to change this from ? to X in the source data?

I'll talk to him about it.
This is why we need degreeOfEstabliment!

@qgroom OK, keep me up to date when you have more information on this matter.
