Topic: Clarification Species Designations

There are a number of species in the R6 dictionary that are listed as Nationally Scarce - on the list NBNSYS0000000047, "Nationally Scarce. Excludes Red Listed taxa". I've not checked all 2500 species, but some at least are not listed in the JNCC designation spreadsheet. As far as I can tell the list was added to R6 after the last JNCC spreadsheet was released (within a few days) so I presume that made it a current, active status. The same may well go for:
Nationally Rare. Excludes Red Listed taxa (NBNSYS0100000012)
Nationally Rare. Includes Red Listed taxa (NHMSYS0021010217)
Nationally Scarce. Includes Red Listed taxa (NHMSYS0021010216)

Can either Chris or Mike confirm that these are indeed current, active statuses rather than redundant out-dated ones?

I'll check with Dario at the JNCC, who maintains the JNCC checklist, and see if he can work out what might be going on :)

Re: Clarification Species Designations

Hi Dave,

These four categories were result of doing some re-structure in the database just after the designation spreadsheet was published. This was to adapt our designations database to the NBN Gateway data model.

If you go to the spreadsheet, specifically to the tab called "Master List" and then filter in column O (Designation abbreviation) by Status-NS and and Status-NR, you will get all the National Rare and National Scarce. Then, if you filter (keeping the previous filter on) in column M (Reporting category), there will be two main options: "Rare and scarce species (not based on IUCN criteria)" and "Nationally Scarce and Nationally Rare Species". The former corresponds to the group of "Excludes Red List taxa" and the latter to  "Includes Red Listed taxa".

In the new update of the spreadsheet, likely to happen before the end of this year, this discrepancy between the NBNG/R6 and the designations spreadsheet will be hopefully resolved.

Regards,

Dario
