As always, I have far more material than time to post it here. While curating photos today, and making sure everything is properly catalogued and safely stored, I ran across photos from a fabulous field trip from last fall. On October 8, 2016, I met John Howard in an obscure part of Pike State Forest, Pike County, Ohio, to look at some interesting habitats. There were low-lying seep-fed fenlike wetlands, and drier prairie-ish openings. As always, we found much biodiversity. At one point, John mentioned having seen a population of an odd little orchid nearby years ago, and we thought it would be worthwhile to try and relocate them. Some images follow...
Even on this late date, the orchids were at or near peak bloom. Even so, it's ridiculously easy to overlook them. Coralroots are myco-heterotrophic; they derive their nutrients by intertwining rootlets with subterranean mycorrhizal fungi. The fungi are the middlemen, funneling nutrients to the orchids. This is a common but imperfectly understood relationship in the orchid world (and many other plants).
Oftentimes, when framing a subject, we would look a bit beyond and there would be another orchid. And another. And more. In all, we located several dozen Autumn Coralroots and it may not even have been a great year for this population. Many orchid species have boom and bust years, and the change in above-ground numbers from year to year can be profound. In a site where relatively few orchids surface one year, a return trip the next year might produce hundreds.
I had not seen this species for many years, well before I got heavily into photography. It was a treat to see this odd little orchids again, and have the opportunity to make images of them.
