Yes, you can make a project for species only found in your area. When a species is only found in one place in the world, thatās called being endemic to that area. I think what you would do is create a list of endemic species and then restrict your project to only those species. I believe thatās what the creators of this project have done: https://www.inaturalist.org/projects/texas-endemic-species
The UK as a whole doesnāt have many endemic species, i think the subject in this case are mostly species that may be widespread elsewhere (like in mainland europe) but only have localized populations in Britain.
Either way, creating a collection project restricted to a list of known species would work
from wikipedia: āThe Brecklands are home to over 120 nationally rare and threatened plant species, many of which grow nowhere else in Britain. With all this diversity, Breckland has received international recognition as an Important Plant Area (IPA). Many of the flora and fauna that are unique to the area have a special protection status, or are part of conservation and rewilding projects.ā
If Iām understanding correctly, I donāt think thereās a way to configure this in an iNaturalist project. Furthermore, it would imply that an observation would be removed from your project whenever that particular species is observed elsewhere -and it would get kind of messy for observations with ids at any level above species-. I think you might be able to retrieve a list of the species youāre interested in using the iNat API (which would require some knowledge in programming) or manually exporting data and using filters or something
I donāt have a list on hand yet, though I could create one. What I had in mind was simply a project that only includes species which have been observed in my area (Breckland) but not anywhere else in the UK. I didnāt necessarily want it to be for known endemic species, just simply for things that have not yet been observed in the UK. I tried using the api and your tool by making a project āproject1ā that was for all species āin the Ukā but ānot in Brecklandā, and then using your tool to select āmust not be in project 1ā but ā must be in Brecklandā. But sadly it didnāt work.
So, currently, I have used the api to download counts of all Breckland species, and am now comparing them manually to Uk counts to see which are only found in Breckland. If I were able to download counts for all Uk species I think I could do it automatically but there is a limit on the export size for the api.
Try this:
Go to iNaturalist website, top menu bar >> More, and select āPlacesā from the drop down. Enter United Kingdom. Then checklist. https://www.inaturalist.org/check_lists/7190-United-Kingdom-Check-List
On this page scroll to the very bottom and download a CSV file. It is a superset of all species from UK and you can apply filters. Like if you remove āblanksā from last observed column, then you get a set of species with at least one observation.
You may want to try a similar checklist for Breckland and then do a vlookup/excel functions to compare the two lists!
okay. so the API itself doesnāt actually have any limits in the number of species / leaf taxa that it can return (as far as i can tell), but that pageās export function specifically does limit the number of taxa that it will return to 10000.
if you want to still use that pageās export function, you could just break up the UK set into smaller subsets. since a third of observations tend to be plants and another third tend to be insects / arthropods, you could make 3 subsets:
Hey everyone! Thanks for all the help. It was a combination of your answers which allowed me to do it successfully in the end. I downloaded the Breckland occurrence and the UK occurrence (following pisums guidance) and then, in R, merged the two dataframes and found those species for which the UK and Breckland observation counts matched.
