Illinois helped revolutionize conservation. Fell, Paulson, and Jack White had just
finished the Illinois Natural Areas Inventory. Now, instead of arguing about
which areas were worthy, Illinois would "follow the Inventory” and
focus on the scientifically selected 610 most important places for biodiversity.
Illinois - out in front of all the other states and the feds - now had a defined mission - to save nature. But had we defined it somewhat wrongly? In
line with the penchants of George Fell, we defined “nature” as areas
“undisturbed by man.” That definition would come back to haunt us, but for now,
it was close enough. We had work to do.
These beauties seduced me to disobey my new boss in my new dream job. Oh, the temptations we don't resist! |
One casualty of the Inventory was a disturbed
little prairie west of Chicago. Palatine Prairie would now be
bulldozed because it did not have enough “undisturbedness.” It failed to be
recognized by the Inventory because it contained less than the needed minimum quarter acre of “Grade A” or two acres of" Grade B." But before the flood-retention bulldozers showed up, Paulson directed me to go there, dig up some endangered
lady-slipper orchids (Cypripedium
candidum), and transplant them to a protected site. This was a bad idea, for so many reasons. (See Endnote 1.)
We should not try to save the Palatine site, Paulson said, because we had more important irons in the fire. He didn't want to disrupt delicate negotiations with the agency that owned the land – and put in jeopardy the saving of a much more important prairie that they also owned. (See Endnote 2, if you want.)

(See Endnote 2, if you want.)
I drove to Palatine with a shovel and some buckets. I parked in
a strip mall, sneaked across railroad tracks, climbed into and out of a
deep ditch, and sure enough, there was open rolling grassland with bits of fair
to good prairie surviving here and there. In a small (less than 1/4 acre) very high quality remnant, prairie
lady-slippers were in bloom – big clumps, nearly a foot across, growing side by
side with prairie dropseed, smooth phlox, hoary puccoon, and other indicators
of “virgin ground.” To dig them up meant digging and lugging gallons of ecosystem that had until today been “undisturbed by man” for all time.
In some high quality prairies, lady-slippers were as common as grass. But these sites are few, and many are losing species and quality fast. |
Did I really want to do this? I did not. It had required
courage for Paulson to hire me, as I had no scientific credentials. I was known
as a conservation activist, writer, speaker, and volunteer catalyst of
prairie restoration. Paulson wanted those skills and that spirit in
the team he was assembling to save those 610 high-quality areas identified by the
Inventory. Others on the team had academic botany backgrounds; I
had on-the-ground and with-the-people experience.
It pained me to stick a shovel into a rare piece of Earth that seemed
unethical even to walk on. These diverse blooming prairie plants had been flourishing
here for thousands of years. Jeweled grassland had extended to the horizon.
Now, in all directions, the animals and plants of ancient nature had been
plowed, paved, bulldozed, and abominated in so many ways. This remnant was both holy and alive. I hesitated. It took deep patriotism toward my new job to
do this. Then I stabbed the shovel into what had until then been
so pure. The violence was the lesser of evils, or so I told
myself. Before stabbing into the edge of the second clump, I paused longer. After
the third I could do no more. Proud new-employee resolution failed. “I must be
crazy,” I said under my breath. “What I’m doing is ugly.”
Okay. I took those three heavy clods of rare orchids and re-planted
them as best I could. Then I defied the boss and saved Palatine Prairie from
destruction. In the end, everyone was happy, but that’s another story. As for the transplants, I
can report that two of those heavy blobs of rare nature have stayed a
part of my life all these decades. This is partly their story. (See Endnote 3.)
And in truth, in its early years this adventure was a
letdown. I had faced ethical challenges at both ends. When I arrived with my shovel at the much higher quality Somme Prairie, where Jerry had directed
me to plant these botanical refugees, I had to agonize over where to dig.
The obvious place would be most like where I found them – amid the finest
prairie plant associates. But that would mean even more nasty shovel-cuts,
degrading yet rarer nature here. It wasn’t going to happen.
To make this enterprise yet more dubious, Jerry had
suggested I do it fast. Not only were the bulldozers soon to arrive in Palatine, but Somme would soon be dedicated into the
Illinois Nature Preserve System. With that change, legal protections would become so strong
that a “disturbance” such as a transplant would require jumping over
prohibitively many bureaucratic hurdles. Once dedicated, as the sentiments and
the rules then had it, you leave nature alone.
Okay, I said, the lady-slippers deserve a chance. Okay, they
need a fine prairie for a home. This lady-slipper was widespread on the
original Chicago prairies. Only three of Somme’s seventy acres were now “Grade
A”. The original lady-slippers here were likely elsewhere, on those now-degraded
other 67 acres. The only way they could likely return was with our help.
We had been cutting invasive trees here. Shade from those trees had
destroyed much of the prairie that hadn’t earlier been destroyed by the
farmer’s plow. Our goal was to nurse all seventy acres back to ecological
health. We expected the prairie species to gradually repossess the ground where
the invasives had shaded everything out.
So here was the compromise. I dug holes near the very high quality prairie, but not in it. A few feet from
“Grade A” was bare soil, where we’d recently clear-cut killer trees and shrubs.
Into these holes went the precious lady-slipper turfs. Soil was carefully nursed
back in (not compacted) around the wounded edges. I amputated all the blooms –
yet another violence. But the dug-up plant is
stressed, and supporting flowers is not where it should put its energies. These three can re-bloom in future years. Now their challenge is to restore damaged roots and
recover from their wounds – and spread over the years as the nearby prairie recovers. We were
idealistic and hopeful – but naïve and ignorant.
Every spring we'd have great hopes – and anxieties – about those clumps. Would they survive in this new habitat? Would they reproduce and
start a whole new lady-slipper community as the holy three acres grew to seventy? Two of the clumps
actually got bigger for a few years, while the third gradually dwindled from 19
blooms to 2 blooms five years later – to zero blooms and zero leaves forever
after. To protect the two, we protected them with wire cages. We watched. Year after year. No babies. Just
the two survivors.
Spoiler alert: four decades later, those two lady-slipper
clumps are thriving, but they seem to have produced no seeded offspring, and
the very high quality prairie has not crossed the few feet of separation to
surround them. They still sit among weeds, shrubs, and other “ecologically
inferior” associates. Our somewhat “leave it alone” approach hasn’t worked for
them.
But yikes! A related, half-thought-out experiment, launched on a whim, would
provoke a whole new drama.
I can’t find a record of the day I decided to be rash. I remember doing it – and feeling queasy about it. Normally I
recorded restoration work in a spiral notebook. This log lists where seeds
were gathered and broadcast, where brush was cut, etc. I shared the notebook
and all its info and questions with all the volunteer leaders who wanted to review it from time to time. Openness was crucial
to our “participatory democracy” culture. By the 1980s, we were becoming seen
as a world model of something new. We committed ourselves to be true to
science, to the ecosystem, and to each other.
I remember deciding not to record my rash act in the log
book, because it would take too long to explain. As Nature Preserve staff, I had the authority to make this decision and do this. But our team followed principles, and I would seem to be violating them. Though we worked collectively on many more degraded sites,
sharing seed among them so they could recover their diversity, Somme Prairie
was different. We had decided, at that time, not to remove seed from it or bring seed to it. We especially
did not plant anything (even seed from other parts of the site) in the Grade A
areas. (We did remove seed from the Grade A, but only to restore species to the
recovering acres that surrounded it. The very high quality habitat was
considered too small to be sustainable without expansion.)
I would have had to explain that this was a special case, that I had been instructed by my Nature Preserve boss to restore the Threatened lady-slippers here, that such a rare and conservative species may thrive only in the highest-quality area, so this was an experiment worth doing. This log book was just hastily scribbled notes. It was easier just to omit all this.
So, what exactly was this dubious experiment that I didn’t log? I
broadcast lady-slipper seeds into Grade A prairie. Shocking? It was to me,
actually. And yet ...
Here’s how conflicting thoughts brought me to throw caution and seed to the wind. The best
and most sustainable lady-slipper populations seemed to be in very high quality
prairie. Until I saw no seedlings from our two big transplants, I’d imagined that the dust-like seeds (in the few capsules that I’d
sometimes notice on our two plants) ought to blow around and make more lady-slippers. But
conservative species (like this one) may reproduce rarely. They live long and "are in no rush." Experts wonder if
they’re adapted to rare (now rare-er) impacts of bison or catastrophically-intense fire or other now-missing
forces and conditions. Perhaps the tiny seeds, sheltered by a canopy of taller plants by the time they mature, mostly
disperse only to the few feet of nearby degraded ground. And maybe they
happen not to “like” those degraded areas closest to the transplants.
Another consideration. As with other orchids, this one
reproduces only when “infected” by (or enters into a partnership with?) some
fungus. Perhaps that fungus only thrives in the diverse high-quality system.
Also, many experts were telling us that
the Grade A ecosystem was a “closed community.” Every niche was filled. Other
plants could not penetrate. A “terminal state” had been reached over the
millennia with roots and leaves filling all the available spaces. And yet? What
if? Does science not believe in experiment? The Illinois
Nature Preserves Commission had directed me to restore the lady-slipper to this
prairie. I was official, empowered. Was a whiff of powdery seed not worth a try?
Did I make notes to record the beginnings of this little
seeding experiment? I hope I’ll find them some day. Or maybe I thought the
likelihood of new orchids was so remote and my memory was so clear, that I
didn’t need a note? Either I’d see baby lady-slippers in a couple of years, or not.
In any case, I loved Somme Prairie, and I was as attentive
as time allowed to its needs and charms. Somme was where I had
fallen in love with prairie nature. Year in and year out I studied and cared
for it - not in this case as part of a job, but as a dedicated volunteer in spare time. From respect, I mostly kept my big feet out of the Grade A areas during the
growing season. One little footpath passed through one part of it, and I
tiptoed down that path when I got a chance. Perhaps in response to our good
care, in some years we noticed newly emerging rare
species, otherwise unknown nearby. These included two-flowered Cynthia, Junegrass, and prairie lily. In 1987 I found the delicate oval
milkweed (Asclepias ovalifolia)
surviving there; until then it had long been thought extinct in Illinois.
Then one day in May 1997 as I walked the little Somme footpath, I
was rocked by a lightning-bolt of tiny discovery. It dazed me briefly. What was I
seeing!?! And what did it mean!?! Ten tiny baby lady-slippers bloomed in that patch
of perfect prairie. Most of the little cuties had one flower and two leaves. This, I
remembered, was where I had broadcast those seeds, perhaps a decade earlier. I
hadn’t still expected to see them. I was thrilled and horrified. What were the
implications? This “unmodified” original prairie was now modified. Forever?
In the twenty years since then, we’ve tried to monitor those
plants annually, and mostly succeeded. They are special. So far as we know, they
are the first of their kind – prairie lady-slippers, planted and grown to
flower. Horticulturists had tried and not succeeded so far. Here, nature did
it.
It’s challenging to do experiments that last for many
decades. They’re rarely funded – especially in organismal botany. But we volunteers can do
such work in the manner of the old-fashioned unfunded scientists, who just
wanted to learn things. Our lady-slipper work is an example of such “citizen
science,” imperfect though it is. It’s had to outlast jobs, places of
residence, life goals, etc. It suffers from some apparently lost data. But the
work suggests some tentative conclusions and testable hypotheses.
They hate living in cages. But they survive that way. More support is needed for humane deer control. |
Even today, not much seems to be known about the longevity
or time needed for reproduction of Cypripedium
candidum in the wild. Extrapolating from other orchid species, it is
hypothesized that, though an individual plant can produce ten thousand seeds
per year, this species may reproduce rarely or sporadically.
In that first year, we found 10 plants, 65 stems, and 27 blossoms. In
1998 seven more plants emerged and then no new plants for two years. As might
be suggested by a new population of young plants, most plants steadily grew
larger until in 2002 there were 20 plants with 187 stems and 146 blossoms. To
compare the dynamics of the population by various measures, see Table 1.
Note that 2002 seems to have been a poor growing year. In
2003, blooms dropped from 146 to 26. Marlin Bowles, who has studied this
species, says that his data suggest that the number of stems and blooms seems
to be determined by the weather during the previous year.

* Average number of blooms per clump in the ten clumps
with the most blooms – appears to reflect short term weather and burn regime.
Peak high numbers seem unchanged from 2001 to 2016.
** The number of stems plus the number of blooms –
appears to be a good measure of overall population vigor. Small stems were not
counted; a stem had to be at least half as tall as the leafy parts of nearby
blooming stems to be counted. Since every bloom also has a stem, this index
gives each blooming stem twice the weight of a sterile stem. Overall, this
index continues to rise.
*** There are now so many tightly packed plants that our previous system is no longer good enough for us to be sure which were new. For the 2016 number we just subtracted the previous high count from the new high total. We do know that many of these plants were new because they appeared in places well away from where we'd seen them before.

We do know that many of these plants were new because they appeared in places well away from where we'd seen them before.
From 1998 to 2008, the vigor of this population seems to
have been remarkably steady. For the first dozen years, the total number of
plants had stayed between 15 and 21, with no apparent trend. Many plants have
gone through periods where they could not be found (despite careful search of
their exact locations) for a whole year – and then emerged again. Other orchids
are also said to remain below ground (dormant? or building up resources
parasitically or symbiotically?) for a year or more.
During 2009 thorough 2011, 59 new plants appeared. These three years were especially good (as were 2001 and 2002) for all measures of
population health. The bursts of higher numbers and new plants likely represent
responses to the precipitation and burn regimes.
Unlike some orchids, the seeded lady-slippers (and the
transplants) seem to be long-lived. All but one of the original seeded plants were in
evidence in 2008 or 2009 and thus had lived for at least 11 years. As noted
earlier, two of the three transplants have remained vigorous for four decades
and were already mature plants when rescued.
The Second Seeding
I was irked not to be able to find the date of the
first seeding. All I knew was that it had been far enough back for me to be
stunned when I saw those first ten plants. How long had they taken to grow?
We did better on the second seeding. On November 9, 1997, my log book records the
broadcasting of four full capsules (“pods”) of lady-slipper seed “in the large
SE very high-quality area … in an arc following the wet mesic topo line.”
I waited anxiously for three years and then tiptoed in to
check for seedlings or flowering plants. I wanted to cage any babies. Deer had
been eating uncaged lady-slippers; so I looked very carefully for even a leaf. (Many uncaged plants we monitored had been eaten – and never
re-appeared.)
I found no results from this seeding in 2000, 2001, 2002 and
on. But I continued to look, with diminishing hopes. Then, another bitty ecstasy, on May 14, 2007, two three-inch stems appeared 15
meters apart, each with one petite lady-slipper bloom. I caged both, in tiny-baby-cages.
So far I’ve found no records from 2008. But by May 2009, one of these plants four taller stems and four blooms. The other had four stems and two blooms. But we also found 30 additional plants – in a distinct arcing line about two meters wide and about 45 meters long – following the route I had walked, opening and shaking seed capsules, a decade earlier.
Some clumps have dozens to as many as 47 blooms, despite intense competition from very high quality prairie. At some point, I suppose, we remove the cages and see what happens? |

This index may be the best single measure of population vigor. Small stems were
not counted; to be counted, a stem had to be at least half as tall as nearby
blooming stems (not counting the blooms). Since every bloom also has a stem,
this weighted count gives each blooming stem twice the weight of each sterile
stem.

Some of What We Learned
- Grade A areas aren’t so
“tight” as sometimes claimed. This conservative lady-slipper fit right in to one of the highest quality surviving eastern tallgrass prairies. High quality areas may have always been more dynamic than we
think. Or the areas we now consider Grade A may be lacking some of the
highest conservatives.
- In the case documented
here, it took most prairie lady-slippers more than ten years to grow from
seed to flower. They seemed to emerge as a full-grown leaf and often a
flower in the first year above ground. Unlike most conservative plants,
they did not start as tiny plants and get just a bit bigger, year after
year. They seemed to live underground, mysteriously, with their fungus,
for many years. It then took about five additional years between first little flower and mature clump (sometimes with ten or twenty flowering stems – or dozens to as many as 46 leaves-only stems).
- Caging from deer made a
“life or death” difference for this species at this site.
- It may be appropriate to
revise or clarify endangered species laws and principles to facilitate
restoration. In the absence of clarity, some people are experimenting with
various degrees of oversight, under varying principles, and often with
less than optimal reporting, often in semi-isolation rather than in much-preferred
collaboration, in part because people don’t know what the rules are or
think they’re counterproductively restrictive. As a result, some people
say “What the hell?! This work should be done. Permits are too hard to get.
So I’ll just work under the radar as much as possible.” Other people fail
to do good work that they believe would be helpful because it might be ‘controversial.’
Both approaches can impede learning and conservation.
- How long does this lady-slipper live? Some of the 1979 transplants are still alive in 2023. That means at least 44 years. But they were mature plants when dug up - and presumably first lived below ground with the fungus associate for ten years. So, perhaps, at least 60 years?

So many reasons: a) most endangered species are rare for a reason and won't survive in any or most new places they might be moved to, b) most of what was important about that prairie was the hundreds of other plants and animals that survived there, c) the plant was just starting to bloom; that made it easier for me to find them; but it's the worst possible time to "rescue" a plant; the best time in in winter when it's dormant, e) and there are so many other reasons. For example, if you care about conservation, it's usually better to spend your time saving what exists, or planting seeds. I rue writing this part of the story, as kind of setting a bad example. But, that's the story. And it's a good story in the end.

When I went to see the engineers at the Metropolitan Water Reclamation District, who would be directing the bulldozers, I asked to see the plans. They told me many times and in many ways that it was too late to change anything. With a friendly smile, I kept asking. When they finally complied, I took a quick look and said, "The Prairie's just in this little corner. All you're doing to it piling some spoil there and later bulldozing it back to make a ski hill. The rare prairie area will end up as it was, but with the prairie dead. Why don't you just pile the spoil in this other corner, and save the prairie as a part of the park?" And they said, "Oh. Good idea."

The truly much more important prairie they owned was Lockport Prairie, and we saved that too, so chill and rejoice!

Endnote 3
An additional puzzle has emerged from the original transplants. As noted above, they seemed not to reproduce but lived as large solid clumps for three decades. Then, in 2010, one of these plants seemed to have produced additional plants, a few inches away from the original clump. Were they suckered offshoots – or new plants from seed? Is it possible that this dust-like seed only managed to travel 5 to 10 inches from the original plants? There are no other plants for 20 meters or so in any direction. By 2017, no large clumps remained. Now both of these original transplants appear to have broken up into separate smaller “plants” – perhaps better called “clumps.” In the journal Lankesteriana 7(1-2) 2007, Carol Wake writes: Cypripedium candidum … reproduces both by seed and adventitious buds from older roots and rhizomes.” For Wake's article see: http://www.redalyc.org/pdf/443/44339813086.pdf
An additional puzzle has emerged from the original transplants. As noted above, they seemed not to reproduce but lived as large solid clumps for three decades. Then, in 2010, one of these plants seemed to have produced additional plants, a few inches away from the original clump. Were they suckered offshoots – or new plants from seed?

We later also transplanted many other lady-slipper clumps from the former Chevy Chase prairie, that actually was being bulldozed. We didn't have to dig them up. We pulled them out of piles of destruction bedlam. Most of the transplants died from too much browsing by overpopulated deer before we figured out what was going on. Once we did, we started installing cages, and a few plants recovered.
Other seeding experiments: In one promising-looking small, good-quality remnant area (that had not been identified as Grade A), where seed was broadcast once in 1997, no orchids have appeared. In a third Grade A area where seed was broadcast on that same day in 1997 and again in 2008, twenty-one young orchids appeared in 2016.

A more detailed and technical report on this experiment is
in preparation and will be referenced here when ready. There are many experiments and much more fun data. But we wanted to get at least
this first draft out to people to consider before another winter/writing season
passed. When the growing season starts, we are stewards and gatherers of data and we tend to leave this thinking work for winter.

Steve,
I know that you know these people already.
But our friends at INHS, Nachusa, and Grand Prairie Friends can work with you on this.
Connie Cunningham and John Marlin (Mermaecologist) know a thing or three.
Maybe even some Master Naturalists can be brought up to speed.
I bought a white lady’s slipper orchid, Cypripedium candidum, from Great Lakes Orchids last spring. I wanted to support Raymond Price’s restoration work with orchids.

Unfortunately, he have since sold out of this species and I don’t think Mr. Price is going to go to the great effort to grow more of them.

I thought it would be nice if Spring Valley Nature Center in Schaumburg had some lady’s slipper orchids in their old farm field restorations for educational purposes. I gave them the seed capsules of the white and yellow lady’s slippers from my garden. Still, I would rather have collected local ecotype seed to give to Spring Valley Nature Center. However, I did not even bother to ask for permission to collect from areas where these species still reside since I know from past experience I would be denied. It probably does not matter much since seed for the restorations at Spring Valley Nature Center are as a general rule not locally sourced.
I have seen two white lady’s slipper orchids growing in an old farm field restoration locally. The whole area was plowed and in crops for a number of decades. The stewards who have been with the site since restoration began have no idea how white lady’s slipper arrived at the site. It is still a mystery much like ear-leaved false foxglove, Tomanthera auriculata, in a different nearby restoration.
You mention sowing seed of white lady’s slipper in high to medium quality prairie. I wonder if you have tried sowing seed in farm field restorations. Lady’s slipper orchids are known in some areas for developing large populations in locations that had been completely disturbed, like road side ditches and old mine sites. It is possible limiting the locations where seeds of this orchid can be spread would limit the recovery. As you know, Nachusa has had great success with eastern prairie fringed orchid, Platanthera leucophaea, in their restorations.
Stephen, great story. Especially the excitement of seeing something come up 10 years later. We recently had the same experience with some seed of conservatives that I planted more than 10 years ago.
When it takes 10 years to first see plants come up from seed, it hammers home the point that it will be years and years (actually I am understating this) before we understand all the relationships that make a Grade A prairie thrive. In the meantime the efforts of yourself and the stewardship community are crucial.
@ Steve Flexman. That's a profound comment. We would do well to invite more people to experience the excitement of discovery. Some great results may not be apparent for 20 years or longer. That means for the Poplar Creek Prairie Stewards (for example, with 30 years heritage of great work), new people inherit stewardship of experiments. If we write up and map what we've done, a person decades from now may be able to confirm a "miracle" or negate a hypothesis - and, in so doing, participate in the hoped-for immortality of an ecosystem.
When we plant shooting star seeds in a recovering prairie, we know it may be ten years before we see them in bloom. Counting the blooms in ten years is rewarding - even if the success rate is just one plant per acre. But then those plants will being broadcasting their own seeds in great numbers, and ten years after that there may a thousand per acre. Or none? Because too many deer ate them all?
Engaging more people with the challenge of monitoring (and discovery) may promote the caring that conservation needs now and, for better or worse, forever.
I know this is an old post, but you raise some points that I've pondered myself. Protecting our most precious places is critical, but there's a cost. The philosophy of "nothing is introduced, nothing is removed" mitigates the function of preserves as refugia. At the very least, it would serve us well to review policies and regulations that limit our ability to succeed on a broader scale.
Because they are such prolific seed-makers, orchids provide a good opportunity for careful experimentation. And, as you say, it's better accomplished in a collaborative, scientific manner than under the radar. Have you tried lab-propagating orchids and introducing them to less-than-top-tier parcels as mature plants? I've been experimenting with C. pubescens on private land that I manage in NW Indiana and the survival rate has been good. It's still too early to gauge whether they can become self-perpetuating populations, but your observations provide some hope.
Rich: Thanks for the good comments and observations. Most wild land today - including most land with "conservation" status - has lost a large part of its natural biodiversity. So I agree with you on restoring species according to a sound plan and with careful documentation. Humble sedges should get as much attention as lofty orchids, in my book, but all types of plants (especially the conservatives) deserve help. If restoration can be done by seed, that seems preferable to me compared with plugs, as the plants are more likely to chose their best spots, bring more genetic diversity into their new populations, and produce more plants with less time investment. The team I work with hasn't propagated orchids, but we restore some species through plugs, if seeds are too hard to get or are not successful (perhaps because of a missing symbiotic soil biota?). Thus, restoring by plug may be an especially important approach when symbiotic soil biota can be included, so soil biodiversity may spread as the plants spread. Best wishes for your work.
