ABOUT THE LIST, 2021
The original Sagehen Master Plant List was assembled by F. Felix from various sources and kept manually updated between 2001-2007. The most important of these sources are Trowbridge (1975), and the Sagehen Herbarium collection (1960-present). The list is now quite complete, accurate and current for Ferns, Horsetails, Gymnosperms and Angiosperms found in the basin. It is possibly less so for Bryophyta, and decidedly less complete for algae (and fungi and lichens).
The Sagehen Master Plant List was imported to iNaturalist in 2012, and the list now includes additions from more recent collecting by F. Felix and E. Krimmel, some* other Calflora records for the basin, plus research-grade iNaturalist observations of plants not previously collected nor otherwise documented in the Sagehen Creek basin. Since 2019, digitized Sagehen Herbarium records are available at CCH2.org, and contain 1620 Sagehen basin vouchers as of 1-28-2021...
This horsetail sends up pale, succulent, fertile shoots early, then sprouts infertile, photosynthetic mare's tails that persist for the rest of the summer.
Trowbridge documented B. lunaria in the woods beside Mason Fen in the early 1970’s, but indicated that it was rare. Elevation range from TJM2 is 3000-3500m. I'm not convinced this plant still oc... More
There are only a few incense cedars within the Sagehen basin, and they are tiny. This appears to be the far edge of their range.
Restricted to high elevations in the basin.
Sagehen's Sugar Pines were largely removed by past logging. But the remaining trees in the basin are blister-rust resistant and used as seed source for nurseries.
Restricted to high elevations in the basin.
Replanting of the Donner fire scar included Ponderosa pines, and they are probably native to Sagehen, as well. This species is highly variable and it's difficult to get a straight answer, but t... More
Collected in the basin by Trowbridge and others in the 1960's and 1970's; not observed since.
Collected in the basin in the 1960's. Easily confused with T. longipes. Look for leafy bract beneath inflorescence.
This plant is highly invasive and grows in several places near the buildings. Please pull it out if you see it!
Collected by Trowbridge in the 1970's. One unconfirmed iNaturalist observation since.
Collected in the 1960's and 2012. Four research-grade iNat obs. TJM2 reports that Acmispon americanus var. americanus is the only California infraspecific for this species.
Found along Stampede Reservoir shoreline.
Added to list from one iNat observation.
Two confirmed iNaturalist observations.
