Battelle Darby Creek Metro Park is where to go to see the Big Darby, and even some of Little Darby, as the two streams reach their confluence in this Metro Park.
The streams are quite unassuming. But underneath their surfaces is a rich diversity of beautifully colored fish and freshwater mussels with bizarre life histories.
So what better place to introduce Weston to a world class ecosystem AND complete our third Metro Parks Hike for the year? Here he is in the backback- If you remember back to our Sharon Woods hike, we forgot the sun shade- but not this time.
However- We DID forget his bib! How fun it was to watch Mom get food all over the place. Murphy's law was certainly in place this day- forget the bib and he'll be sure to be extra messy with his baby barley cereal.
On our way along the trail, we encountered things like cutleaf coneflower, Rudbeckia laciniata.
And in higher drier meadows we saw one of the cudweed species in the genus Pseudognaphalium.
And we also got to introduce Weston to map turtles. This female was basking on a rock in a large pool created just downstream from the confluence of the Darby Creeks. She was absolutely huge, probably 10 inches long- dwarfing her male counterparts at the other end of the rock.
As we returned north through the most mature woods along the trail, I happened to spot the plant pictured above. Weird, I thought to myself, I've never seen this. I thought it might be an orchid. A quick e-mail to my colleague Rick Gardner after we returned home and he confirmed that my suspicion was indeed correct. He identified this as the autumn coralroot, Corallorhiza odontorhiza. Some plant species produce flowers that never open and are self fertilized- botanists call these cleistogamous flowers. Autumn coralroot can produce both types of flowers, so it is possible that these flowers will open eventually, or it is possible that they will remain closed and self fertilize.
Hot off the Compact Flash card- I took this image on Wednesday evening while shooting insects on our Canada Goldenrod patch in the backyard. Absolutely amazing! This is an ambush bug, in the subfamily Phymatinae , and possibly in the genus Phymata. Isn't it cool?
As you can see over Megan's shoulder, the first portion of the hike led us through an old field dominated by Canada goldenrod.
I kept an eye out for butterflies, but the only one I observed was this pearl crescent, one of the most frequently encountered butterflies in Ohio.
After the old field, we entered a young woodland with several "wolf trees". These trees, often much bigger than most of the forest, were remnants of a time when this land was probably pastured or farmed. The old trees would have been surrounded by crops or grasses. At sometime in the past, the land was abandoned, allowing tree seedlings to become established. Since they were all competing against each other, these trees grew quickly and very straight, in contrast to this large open grown oak.
A little further down the trail brought yet another old field opening, this one much smaller. It supported a nice population of grease grass, Tridens flavus. This species seems to be relatively common in central and southern Ohio especially in old fields and infrequently mowed roadside habitats. If you run your hands up and down the stem and panicle, you'll feel why this plant is given the name grease grass- it somehow produces an oily substance- if you haven't felt it, it's really neat.
Another species growing in this meadow was Sorghastrum nutans, or Indiangrass. One of our showiest native grasses, I'm not exactly sure what it was doing here. It is native further west in Franklin County in the Darby prairies, but here it may have been planted or introduced from mowing equipment. It could have been a natural population, but I'm guessing that it is more likely introduced at Sharon Woods.
With Megan carrying Weston, she kept continuing hiking on, especially after my grass photography. It was taking too long- and he is heavy.
It's hard for me to not take a photograph of a honeylocust trunk covered with protective spines. I just find those spines amazing. The honeylocust is considered an example of an anachronistic species, first described by Dan Janzen and Paul Martin in 1982. The gist of this theory is that this tree species' protective spines are no longer needed because the giant herbivores that this tree evolved with and developed these spines to protect against are now extinct.
We crossed over a small stream that was full of minnows- although I've only dabbled in identification of Ohio's fish, if I had to guess- this is a creek chub.
Out of the forest and back into the old field, I did spot a few birds, including this field sparrow.
And, what I think is a song sparrow.
After just short of two miles of hiking, we finished the loop, and stopped to take a break before we got into the car. "Dad, that was fun hike, but I really just want to eat your camera!"
