remove native birds from unified checklist #32
Comments
It would be good to have an column included here with the reference to the source checklist. I included this in the extract of the unified checklist (field |
@timadriaens the species you list are no longer included since we removed RINSE https://doi.org/10.15468/focajn, except for:
The only we can remove those is by specifically excluding them in our processing |
Updated the spreadsheet @LienReyserhove created. The remaining birds are:
|
All of these are non-native, except for these goose species for the reasons outlined above. Question @peterdesmet : would it not make more sense to remove them from the source checklist on which they apparently occur (because this is a mistake in the source checklist...)? And second: shouldn't we publish the alien bird checklist and give this one priority over the other bird related sources perhaps this will solve this problem? Anser fabalis (Latham, 1787) |
Removing from source checklist: yes, we could remove those distributions there, but then it will differ from what was included as supplementary material to the paper. Bird checklist should get higher priority, but since they won’t be included there, they will still pop up from rinse pathways. |
Clearly the supplementary material to this paper contains mistakes (also for the UK as one reviewer of that paper pointed out to me). For me, this shows that expert check is missing as a step in the pipeline to the unified. @peterdesmet @damianooldoni any ideas on how to tackle this issue of mistakes in the source checklists? Maybe, instead of prioritizing at checklist level, we should prioritize at [checklist + taxon] level i.e. we discard the birds from the RINSE pathway checklist and include the bird checklist? But then again, such decision for me needs to be based on expert review first. |
I agree with @timadriaens that we should first get the list reviewed by experts, before we start prioritizing lists in the pipeline. We now have the checklist published, the next step is to get it reviewed. |
I realize this is probably not feasible within the TrIAS project and we have other priorities now, but at least such gaps should be pointed out/documented/published. |
Hi all, 2 more cents : Before the unified checklist was up, I used the different source checklists to target our exotic taxa. Some native (eg. Astacus astacus) were listed in the RINSE checklist, before we target only exotics for belgium by joining the distribution table. Just to let you know this issue even if I guess it was taken into account in the unified checklist. |
@mcoupremanne Podarcis muralis is there because it is non-native to Flanders (introduced with habitat material probably and still spreading along the railway network). We should indeed decide what to do with such cases, because it is strange they appear on a belgian alien species checklist. The same is true for Natrix natrix, introduced in Flanders. Both species represent some conservation value, but they are alien to the Flemish territory. Anser anser and Branta leucopsis: see above, they are mixed populations of wild and escaped birds, we decided to rule them out of our definition of 'true aliens'. |
Upon working with the unified checklist, these issues still needs to be tackled. The 3 geese should be off the unified in one way or another. We decided that we would not include them on the bird checklist, so for consistency using the same argument they should also be taken out of the other cheklists that have them (RINSE and RINSE pathways). I feel there is nothing wrong to make such decisions at source checklist level and it can all be mentioned in the metadata to the source checklists. @peterdesmet @LienReyserhove any thoughts? |
We can include a step to exclude certain species 👍 That would be these ones: Anser fabalis (Latham, 1787) ? |
yep |
This is now fixed in the pipeline and repo data, but I don't really see a need to republish it to GBIF just for that. |
I should then remove them from preprocessing pipelines of indicators. Otherwise I get them, e.g. |
Issue trias-project/unified-checklist#32 has been closed.
while checking the birds extract from the unified there appear to be a number of species native to Belgium on the unified checklist
these would imo best be taken out of the unified for now @LienReyserhove .
