Saturday our veteran team of rare plant monitors went out to hunt the dangerous purple-fringed orchid (dangerous because I've broken several bones, on two occasions, on the search!). We located two new plants at one site, two others we had located previous years, and were feeling quite pleased with ourselves and optimistic about our next foray. After a wonderful lunch of Thai food in a cute restaurant not too far away, we ventured over to our second location. Again, two plants re-located, and two new babies : ). But the bad - I mean REALLY bad - news is that they were all awash in a sea of reed canary grass. And if we can't get rid of all the RCG there, the orchids in that area are doomed. : (
This is so characteristic of the efforts to save our precious endangered species - letting the invasives get even a tiny toehold in our natural areas can spell doom for the plants and animals we love and want to preserve!

This weekend we finished up our Cypripedium candidum monitoring. It's amazing how well they do with a prescribed burn! There were many in this tiny railroad prairie, full of conservative species such as yellow star grass, hoary puccoon, vanilla grass and blue-eyed grass. The spring weather was also more temperate and rainy, so perhaps that has some effect on the orchids. But the burn set back the brush, restored nutrients to the soil, and reduced the number of weed seeds. Next year, who knows?
Speaking of weed seeds, we saw a flock of goldfinches yesterday at Volo Bog, eating the seedheads of the abundant dandelions! I wish I had a flock of goldfinches in my yard, manicuring away at my dandelions! : ) We also saw way, way too much reed canary grass there in the bog. There are at least a dozen endangered and threatened species in a very small area, all vulnerable to takeover by this invasive alien plant! I alerted the state ecologist; hopefully that will help matters?

This past weekend was a two-fer: Saturday we monitored Cypripedium candidum in a high-quality prairie in western Chicagoland, and on Sunday I drove about 150 miles (getting lost twice, unusual for me!) well into farm country to climb a wooded hillside to see Galearis spectabilis on the edge of the slope, in afternoon sun and glorious bloom! This was the first time I had ever seen this particular beauty.
In many states it is declining quickly, and now I can see why: this particular hillside is rapidly being overtaken by garlic mustard, whose antifungal properties spell doom for the ground-dwelling fungus that nourishes our native orchids. We spoke with the landowner about the joys of orchid conservation and the need for keeping garlic mustard and other invasive species at bay, and will hope they will do the management essential for the orchid's survival.
The gentleman said there used to be a large colony on his property years ago, but it had disappeared. This is the first one he has seen in many years, probably due to the abundant rains this spring? The floral associates were Virginia creeper, bedstraw, poison ivy (always!), black and white snakeroots, carrion vine, jack-in-the-pulpit, wild grape, clearweed, sweet cicely, and balsam ragwort. It seemed very happy nestled in its bed of white pine needles. The tree diversity was very high there; the woods seemed not to have been logged, in recent memory, anyway. There were white pine, shagbark hickory, American elm, hackberry and black cherry nearby.

Today we went on our first rare plant foray of the calendar year - for the native dog violets, locally abundant only in a few pristine wooded areas. Unfortunately heavy, intermittent thunderstorms started right as we were setting up our survey, so we weren't able to safely monitor this weekend, but we did find a great Moroccan restaurant within reach, afterwards, and had hot minty tea and a wonderful tagine in its traditional ceramic cookpot. The company was great and we spent time discussing art, kids and upcoming monitoring plans, so it was time well spent.
The early-season marsh marigolds (Caltha palustris) were in their full golden glory and spring beauty, trout lilies and other early spring woodland ephemerals are well along. The trilliums are not yet up. Although our monitoring team has learned to easily ID dog violet, a stemmy, trailing violet with long-spurred light purple flowers, even out of bloom, it's just more fun to see them in their full glory, so I think we'll wait another week. I hope the weather is better next Saturday! : )

Well, the trillium series is finished - for now. Just in time for the next exhibit at Whole Foods River Forest's cafe and gallery. (Whew!)
Illinois is home to nine species of trilliums: Trillium grandiflorum (the large white trillium everyone thinks of when you say trillium), Trillium sessile, Trillium cernuum, Trillium nivale (the dainty snow trillium), Trillium recurvatum (probably the most common species in our woodlands), Trillium erectum, Trillium flexipes, Trillium viride and Trillium cuneatum. I grouped the series - or tried to anyway - most logically by color. The painting above is of the two green trilliums, T. cuneatum (left) and T. viride (right).

Groundhog's day has come and gone, and six more weeks of winter is yet to come, love it or not. I keep thinking about all the sweet orchids and other rarities enjoying their winter sleep, and wondering how they'll fare this coming year. In Illinois, the numbers on the white prairie fringed orchids had tanked in previous years but it seems that there is a very slight upswing because of the wet springs we've had the past two years, and attention to management in some areas. Drought is very hard on them, and unfortunately all the good management in the world can't make up for loss of rainfall....
I've been sidetracked from painting by other projects - church stuff, this orchid article, advocacy for the Mike Quigley congressional campaign, but now it's time to get back to the boards and get a few more finished - I have an upcoming exhibit at Marion Street Cheese Market. What to paint, what to paint??? (And no, I'm not painting cheese! I'm still painting orchids! : ))

My hunch that the stemless pink ladys' slipper being possibly extirpated has been borne out by last spring's visits by the state botanists, who found only thick colonies of buckthorn and multiflora rose where the plants had been last seen. Management is so crucial to our natural areas' health! We need more dedicated volunteer corps all over the state to adopt these natural areas and keep the invasives at bay so that future generations may continue to enjoy and treasure these beauties as we do.
The good news is that with management and volunteer commitment, a few new populations of native orchids are being discovered, or rediscovered, each year. The federally listed prairie white fringed orchid was identified at a new site in northern Illinois last year, after years of population declines. I am hoping to be able to locate and talk with botanists who are studying native orchids in hope of learning what are the most serious threats and the best management strategies for combatting them (and by that, I'm ruling out the ones we already know: loss of habitat to real estate development or agriculture, changes in hydrology, trampling, poaching, and global warming for boreal species).

Happy New Year! In spite of gloomy economic news, I try to keep sane by continuing to seek beauty in the world and attempt to paint it. The orchid pictured below, the stemless ladys' slipper, is listed as Endangered in Illinois. Today I learned that no one has seen it in almost ten years - contacting people about the two state records informed me that it's very possible the plant is extirpated. At the very most, there is probably only one colony remaining, and its numbers have plummeted over the years so the news isn't good...
I feel like the authors of the book "Last Chance to See," who travelled all over the world documenting the last years of endangered animals such as the Yangtze River dolphin. Where will this sixth global extinction, in which we are currently living and participating, finally leave us? I shudder to think, but I also believe that human ingenuity, community and caring contains all the answers to solve our weighty global problems.
