First steps in Species Distribution Harmonization


First steps in Species Distribution Harmonization

Started by Paulo MIRANDA Replies (3)

Dear all,
I'm new in the harmonization process and i'm trying to do it in species distribution datasets.
1 - The first question that i have is related to distinguish between species distribution dataset and species distribution unit. As i could understand i may assume both like this example:
SD dataset - "article_17_habitat_Directive_report";
SD unit - each species distribution layer inside the SD dataset, each unit will have only one species distribution inside.
In this sense if i have, for other purposes, only one species distribution in one dataset it could be like this:
SD dataset - "Canis_lupus_distribution";
SD unit - only one specie distribution related to Canis lupus.
Am I correct in this assumption?
2 - The second question is related to the "referenceSpeciesId". The specifications states that this value must be firstly from the eu-nomen list. But for the example, "article_17_habitat_Directive_report" since all the species have their own codes in the Natura directives is supposed to change them to the ones from eu-nomen?

3 - In case, to have to use the eu-nomen ids, i have doubts related to the code to use. for example:
the specie "Calonectris diomedea" has the Natura 2000 id A010, the Eunis id 940, and this GUID  " |" in the eu-nomen page (
What should be the eu-nomen id? 137194? or all the GUID?

Best Regards,


Paulo Miranda

    Hello Paulo,

    1 - I guess this is correct.

    2 - the DS says: "Each unit specifies a referenceSpeciesScheme which refers to a choice of three widely known reference lists and a referenceSpeciesID refers to an ID from that reference list for the given species
    of interest. EU-Nomen is the preferred reference list to be used. If a taxon is listed in EU-Nomen, this
    reference must be used as first choice.
    If it is not listed in EU-Nomen, the second choice is EUNIS, if
    not in EUNIS, Natura2000 can be used...", thus, yes, you have to use the EU-Nomen ID.

    3 - Figure 2 of the DS for SD shows an example, where you can see that you have to give the full URL, e.g.  NOT only the GUID itself.

    Yours, Dirk Hinterlang

    Dear Paulo and Dirk,

    I agree with your assumptions, I just add a snippet for the encoding of the referenceSpeciesId in the gml file:

                        <sd:referenceSpeciesName>Calonectris diomedea</sd:referenceSpeciesName>
