Nature Preserves of Kane County: Ferson Creek Fen

Last Sunday, I trekked out to Kane County to tick numbers 43, 44, and 45 off of my list of Illinois nature preserves: Ferson (or Ferson's, depending on the source) Creek Fen, Norris Woods, and Nelson Lake Marsh.  Results were mixed.  Today I will just deal with...

43:  Ferson Creek Fen.  Dear Kane County, your parks and preserves are very nicely groomed, in that they have good signage, well-kept trails, and immaculate parking lots.  However, when one is situated so far away from civilization, it would be helpful to include even the most primitive of bathroom facilities, especially when your vegetation is too sparse to provide adequate cover for outdoor peeing.  It was a long drive out there, and I could not fully enjoy your preserve due to mounting pressure on internal organs.  Just a thought for the future.

FCF is a rather small preserve, the fen/marsh area walkable in a short time.  There is also allegedly a prairie trail, which I didn't explore because the literature doesn't make it sound like the showcase area of the site.  And there were more pressing matters on my mind, pun intended.  Near the first overlook platform, I was greeted by this ominous gatekeeper:


The poor little guy was shuddering and heaving with every breath, obviously in its final death throes.  I finally passed by it when I determined it was too feeble to launch itself at me in a rabid fury.  When I passed by it again on my way out of the overlook, it was too weak to even raise its head; it just rolled its head around on the ground and followed me with its horrible, sad, very human-like eyes.  Then I spent the next ten minutes choking back tears, probably not a reasonable response to the impending death of something most people consider vermin.  On to the botany!


The area to which the preserve map referred as the fen didn't appear to have any of the characteristic alkaline-loving fenny species touted by the INPC guide--turtlehead, grass-of-parnassus, Kalm's lobelia, etc.  I squished around in it for awhile, but all I could find were some nice quality marsh species, like the marsh skullcap above, and the marsh bellflower below:


It also had a nice thick mat of marsh shield fern, and some common species like Eupatorium maculatum and Verbena hastata.  Maybe I didn't squish around long enough or far enough to find the typical fen species.  Then there came an area along the trail populated almost exclusively by Sagittaria latifolia and this stumper:


A Hypericum, obviously.  It had fairly weak stems and formed a thick mat.  It doesn't appear to be any of the Hypericums listed in the Kane Co. plant guide.  Going through the Swink & Wilhelm key, it has more than 20 stamens (right?), petals solid yellow, plant herbaceous (not distinctly shrubby), flowers less than 3cm across, and I'm pretty sure the sepals were flat.  That brings you to H. sphaerocarpum, which does not have an official record in Kane County (although almost every other county in IL has it).  Did I find a new county record?

Then there was this species, which looked like nothing I knew.  For the first time in ages, I had to go through the entire S&W key, because I couldn't place this to genus or even family, and I hadn't brought Newcomb with me (or Kane County Wild Plants & Natural Areas, doh!).  Ah, yes.  Justicia americana, water willow.  Which I HAVE seen before, but very long ago.  There was quite a healthy stand of this lining the banks of the Fox River.  The damselflies were getting a kick out of it.

Circling back toward the parking lot, I took the boardwalk through what might have been a nice marsh in the days of yore, but is now a cattail desert.  The only thing that will save that part of the site from certain doom is a good aerial nuking with herbicide.  Or several. 

Final verdict:  Some nice spots, but definitely in need of some lovin'.  Celebrity species are either kaput, dormant, or hiding in hard-to-reach nooks.  Problem species:  cattail, RCG, purple loosestrife, glossy buckthorn.  An OK place to visit, but maybe not worth the trek from the city (unless you're on a quixotic quest to conquer all of the IL nature preserves, like some loonies who shall remain nameless).

Getting back on track: months-late recap of Sagawau Canyon Nature Preserve

[blushes wildly]

It has dawned on me that I have not posted anything in 3+ months.  Flat out, this is because my job is hellacious, especially the last month and a half or so of the school year.  You have been out of school for over a month, you say?  Why, yes.  I fled the continental US immediately after I escaped the clutches of my workplace, for a week's trip to Puerto Rico; then, I spent several weeks catching up on all of the errands and stuff I am not able to do during the school year because I am a slave to my job, and any miraculous free moment I get is spent melting like a puddle of slime mold into my couch.  It wasn't until last week that I was actually able to get out in the preserves for some unfettered nerd-bingeing.  But before I dissect that, I will recap a visit I made in May (for school, of course) to another as-yet-unvisited (by me) spot on the IL nature preserves list:  Sagawau Canyon.

Camp Sagawau is a frustrating place, in that you must make an appointment, or attend a special event, to go there.  Since I care not for pre-planning, I had never been there.  Luckily, having a troupe of students who need edu-ma-cating is an accepted reason for visiting the place, so I brought ALL of my AP students, both classes, 54 in total after absences, all at the same time, to get a grand tour of the place for their spring field trip.  I am not a well woman.  However, it turned out great, because the staff there are wicked cool and brusquely divvied up my kids into 3 groups and shuffled them through SIX different activities throughout the course of the day.  Kicknetting for benthic macroinvertebrates, water quality chemical analysis, limestone canyon tour, garlic mustard pulling, prairie tour, and herpetology lesson.  Pretty sweet.  I, of course, was free to tag along and look at plants while the guides talked about geologic history of the Chicago region (which I already know).  Here are some of the highlights of the day:

About half of the kids hanging out in the gorgeous environmental learning center.

Collecting water samples in the high-quality stream for chemical analysis.  If I remember correctly, this rocky-bottomed stream is spring-fed, and flows to its doom in the Cal-Sag Channel.  I would wish that on only my worst of enemies.

Netting benthic macros.  They were very timid at first about getting wet and touching squishy things, but they quickly got over it.

A baby northern water snake one lucky dipnetter caught.

The staff, having to do chemical tests all the time for school groups, had a sweet setup near the stream with tables and kits neatly lined up.  I am forever spoiled.

Trying to identify our benthic macros. This looks like an arranged photo for some kind of educational brochure, but I assure you it was candid.

The dolomite canyon.  Allegedly, the only one in Cook County.  They also claim that a tiny cave in the canyon wall is the only cave in Cook County.  I find it difficult to believe that one can confirm such a claim, but I'll let them have their fun.

 On to the flora...some lovely columbine against the canyon wall.

Cornus alternifolia, or the prosaically-named alternate-leaved dogwood.  It's pretty unusual in these parts, preferring to hang out in calcareous places.  

 Cystopteris bulbifera, bulblet fern. The little-bitty bulbs on the underside of the blade allegedly drop off and spawn baby ferns.  Can one use the word "spawn" when referring to plants?  If not, you're all just going to have to deal with it.

That's all the flora I captured, sadly.  Too much of my attention in the canyon was spent making sure my kids didn't slip off the rocks into the stream.  But overall, I give this site a thumbs-up.  Good quality stream, rare habitats, neat geology, great staff, fun times.  I'm actually glad they regulate visitors, so that they can maintain the quality.
