Hello iNaturalists,

The Oregon Biodiversity Information Center, which administers this iNaturalist project, recently published our updated 2019 Rare, Threatened, and Endangered Species of Oregon book. Statuses and distributions for many hundreds of Oregon's rare plants, animals, and fungi are listed. You can download the PDF or browse our Rare Species Publications page for Excel excerpts and supporting information.

I have updated this iNaturalist project's species list to reflect many of the additions, drops, and name changes made in our 2019 publication. In particular, we added a lot of fungi during this round of list revision. Generally when we add a new species to our list, we place it on our List 3 - Needs More Information list. These are species where there is some evidence for rarity, but we need more information to assess its status, or perhaps with more information we learn that it is too common to be listed.

If you're curious about our ranking definitions or ranking methodology there are plenty of resources online for your perusal.

Happy observing!
Lindsey
