Fun with iNaturalist

I’ve started uploading some observations of plants and occasional other critters to iNaturalist.org. iNaturalist is a project of the California Academy of Sciences that serves as an on-line place “where you can record what you see in nature, meet other nature lovers, and learn about the natural world”.

For me, iNaturalist is one more place (aside from the Consortium of California Herbaria, Intermountain Regional Herbarium Network, and CalFlora) where I can see what others are finding in the Bodie Hills, Hot Springs Valley, and other places I like to visit. It’s also a way to get acquainted with some invertebrates and other organisms that I don’t have the training to identify easily myself. You can also help other people identify what they’ve observed, ask for help identifying some of your observations, create “Places” (like the Bodie Hills) as geographic filters for lists of observations, and follow or communicate with other observers. There’s also an app that lets you record observations in the field.

There are a few drawbacks — photos don’t always capture the characters needed for accurate identification, and an observation may get labeled “research grade” even if two people agree on the same identification that happens to be incorrect. On the whole, though, the community of observers (a mix of amateurs and professionals) seems to get things right, providing a useful and user-friendly addition to the knowledge-base on biodiversity.

The project is still young and it will be interesting to watch it grow in the years ahead. iNaturalist began as a student’s final project in the UC Berkeley School of Information in 2008. It was acquired by Cal Academy in 2014 and has a small staff supporting the project. Do you have photos of identifiable biota in Mono County or anywhere else in the world? Share them on iNaturalist!

The Checklist: New 2017 Edition

I’ve made some corrections and additions to Plants of the Bodie Hills: an Annotated Checklist, based on some fieldwork and other research during 2016. CLICK HERE to visit the Downloads page. The January 2017 edition of the checklist is a 47-page, 5.1 mb PDF file. [UPDATE, January 16: A few more typos corrected. You may want to download again if you downloaded prior to 1-16-2017.]

Checklist Cover 2017

The Bodie Hills encompass about 417 square miles in northern Mono County, California, western Mineral County, Nevada, and southern-most Lyon County, Nevada. The checklist includes 679 taxa of vascular plants, of which 575 are definitely known to occur in the Bodie Hills and 104 others are considered likely to be present. The list includes 52 families of dicots, 15 families of monocots, and 8 families of vascular cryptogams.

Travertine Hot Springs

Travertine Hot Springs has extensive alkaline wet meadows and dry outcrops.

Cinnabar Canyon

Cinnabar Canyon contains pinyon-juniper woodland and an unusual wet meadow.

Bodie Mountain

Bodie Mountain supports high-altitude sagebrush scrub with lots of
cushion plants and several alpine species.


Bodie is in the south-central Bodie Hills.

The Center of Diversity for Boechera

Did you know that Mono County is home to more species of Boechera (“rock-cress,” in the mustard family) than any other county in the United States?

Neither did I, until I ran across a web page with 103 maps showing the number of species per county for the “Largest Genera in Continental North America”. This analysis is part of the Biota of North America Program (BONAP) (Kartesz 2015a, 2015b). The overall distribution patterns these maps reveal are interesting, and perusing the maps for familiar genera and favorite places is also enlightening. For example:

Inyo County, CA boasts the greatest diversity of Eriogonum (55 spp.), Phacelia (43 spp.), Lupinus (40 species), Cryptantha (24 spp.), and Ericameria (24 spp.).
San Bernardino County, CA has the greatest variety of Mentselia (24 spp.), Gilia (23 spp.), and Galium (20 spp.).
Garfield County, UT has the greatest numbers of Astragalus (59 spp.), Penstemon (31 spp.), Oreocarya (16 spp.), and Cymopterus (11 spp.).
Juncus is most diverse in Plumas County, CA (33 spp.).
Castilleja is most diverse in Fresno County, CA (21 spp.).
Artemisia is most diverse in Fremont County, WY (18 spp.) and nearly as diverse in Elko  County, NV.
Calochortus is most diverse in Kern County, CA (17 spp.).
And so on. As one might expect, the larger and more physiographically diverse counties are favored to have high numbers of species for large genera in the arid western states (e.g., Inyo, San Bernardino, Nye, and Coconino Counties). Perhaps grouping some adjacent small counties together would shift the locations of some hot spots.

Mono County, then, is the center of diversity for Boechera, with 36 species (listed below). Sixteen of these are known or appear likely to occur in the Bodie Hills. No wonder I didn’t find them all during my field work 30-some years ago, and no wonder I gave up trying to key all my specimens and shipped them off to Reed C. Rollins (1911–1998), a professor of botany at Harvard University, and the renowned expert on many Cruciferae, including what we then called Arabis. He kindly annotated them all and shortly thereafter cited several of my specimens in describing Arabis bodiensis (now Boechera bodiensis) as a new species from material previously identified as Arabis fernaldiana var. stylosa. Rollins (1982) wrote, “Furthermore, an extensive sampling of Arabis populations of the Bodie Hills by Tim Messick has shown that what we name A. bodiensis below is consistent in its characters and is present on many appropriate sites throughout the area. This adds up to the necessity of recognizing the Bodie Hills material as an undescribed species.”

The rock cress species are fairly challenging to identify. One often needs flowers (for their color), leaves (for their shapes and trichomes or hairs), intact fruits, and mature seeds to run a specimen successfully through the keys. Most Boechera plants don’t provide all of these parts in good condition all at the same time. One may need to key the same population in both spring and summer (taking notes and photographs) to do the job well. Familiarity and practice make for easier and more reliable identifications in any large group of plants, so the key to getting good with Boechera may be to live in or near Mono County.  Or Inyo County, which has nearly as many Boechera species.

And finally, the elephant in the room is of course: How does one pronounce the name Boechera?  “BOH-chera” (long O) appears likely or even obvious to most Americans, but “oe” in Latin names is always pronounced “ee” (long E), as it should be in Oenothera or Oenanthe. So is it BEE-chera? Boechera is named for Tyge W. Boecher (1909–1983), a Danish botanist, evolutionary biologist, plant ecologist, and phytogeographer. But the Danish spelling is Böcher (with an o-umlaut), and this would suggest the “oe” (or ö) should be pronounced more like the “oe” in the French words oeil (eye) and oeuvre (an artist’s collected works). This sound can’t be spelled in English, but “BUH-chera,” with a listless enunciation of the first syllable, comes close. Or maybe “BOO-chera.” Take your pick.
