List of new plant additions to the basin Master Flora

I thought I should just make a running list of the new plants added to the basin master list from your iNaturalist observations. Keep up the good work! It's amazing that you are still finding so many new species of plants and animals, given that scientists and students have been searching all over the basin for over 70 years. There's just no substitute for more eyeballs!

If you are interested in live observations of one of the plants on our list, search the Sagehen iNat records for the species of interest. It should be said that a few of these plants may have been collected for the Sagehen Herbarium in the past. However, there have been many taxonomic splits in the intervening decades, and we are in an ongoing process of "discovering" these old specimens all over again! If you would like to help with our herbarium IDs of these and other species, please see our records at CCH2.org (deselect all, then select "SCFS" and search on "California" to show all our basin records from both Nevada and Sierra County (we straddle the line).

There are also many plants that were collected at Sagehen in the past that apparently no longer exist here. This is at least in part due to forest succession after the 1960 Donner Ridge Fire that wiped out 1/3 of the basin forest. With the Sagehen Forest Project thinning and prescribed fire treatments, some of these plants (and animals) have been spotted again in recent years!

Notes:

  1. * indicates a plant that I’m certain is represented in the Sagehen herbarium. Un-starred plants may or may not be. Check our digital records in CCH2.org to confirm.
  2. I add the plants to this list under the year they were identified, which is sometimes long after they were observed. In that case, I make a note of the year these observations were originally added to iNat. 2023 was a great year largely thanks to a moss workshop at the station, and Shane Hanofee's work on a new flora for Nevada County--thanks @sapienshane! And there are a few observers who are just disproportionately productive: @phantom-sweattb and @chrisophylla stand out--thanks for your sharp eyes!
  3. Also, if you need a programming project, it would be great to have a tool for comparing the Sagehen plant lists on iNaturalist, Calflora, Symbiota. As it stands, I have to just make a manual note when I see something that I recognize as new pop up, and we are probably missing a lot.
