Pan-species Listing (PSL)

The checklist used for pan-species listing is based on the UK Species Inventory (UKSI), which is the standard reference for names and taxonomy for all species of flora and fauna in the UK, and is maintained by the Natural History Museum.

The PSL checklist uses UKSI English and scientific species names but differs in using fewer taxonomic groupings that are preferred for listing, e.g. combining the UKSI "informal groups" of marine mammal and terrestrial mammal into a single Mammals, and including horsetail, fern, ginkgo, quillwort, clubmoss, and conifer, with flowering plant, into Vascular Plants. It also removes many exotic species that UKSI includes but are not deemed appropriate for listing, e.g. escapes that are clearly not established in UK.

If you believe any species are missing, or have other comments about this list, please Contact Us or post in the PSL Forum. We will ensure any necessary changes are relayed to UKSI, and may add new/missing species to our list as 'provisional'.

First select authority to copy existing species from, then type species name, or enter a new species directly.
Species name is defaulted from the previous species row and should of course be overwritten!
Genus is defaulted from the previous species row but may need overwriting; specific needs to be entered in either case.

NB: Species name for the old taxon should be updated to differentiate it from the split taxa using a '/' or '[group]', e.g. Species A/Species B or Species A [group].
NB: Scientific name should also be updated similarly, e.g. Genus specific A/specific B or Genus specific A [group]
NB: Notes only allow up to 255 characters, but there is no enforcement of this. Anything longer will be truncated without warning.
NB: Species name for the old taxon should be updated to differentiate it from the split taxa using '[lumped]', e.g. Species A [lumped].
NB: Scientific should also be updated, using '[lumped]' or brackets for the old specific name, e.g. Genus specific [lumped] or Genus [specific] subspecific.
NB: Notes only allow up to 255 characters, but there is no enforcement of this. Anything longer will be truncated without warning.
