Phenomenal Fen

Recently Chad Zirbel posted a photo of a stunning orange lily that I just had to see for myself. He directed me to a nearby high-quality prairie fen. This habitat is flooded with calcium-rich groundwater which selects for a unique community of plants, many of which are adapted to this specific habitat.

The spongy peat and dense communities of sedges where unlike anything I’d seen before.

I got a bit lost though before I made it to the fen, and when I was wandering around the surrounding forest I found this incredible fungus. It looks a lot like the bleeding-tooth fungus (Hydnellum peckii)but with clear secretions instead of red. I suspect this is a related species but I’m not sure. It was visited by lots of small flies and wasps, I like thinking of what this oozing structure would be like to a 2 mm long insect.

I also found this spiky tachinid fly calming visiting flowers, a much more charming place to hang out than the innards of some other animal where it came from. Most tachinids are internal parasites and judging by the size of this fly I’d guess it came out of a vertebrate of some sort.

I found the Michigan Lily (Lilium michiganense)! This species is actually found throughout much of the midwest and southern US and is commonly cultivated. Still, it was a stunning sight to see this one erupting out of the dense mat of prairie grasses.

Swamp milkweed (Asclepias incarnata) is the water-loving cousin of the common milkweed that is commonly seen along roadsides.

Black-eyed Susan (Rudbeckia hirta) is not really a wetland plant but it seemed to be doing just fine in this soggy habitat. There were many more plants that were surely more rare and unique to this habitat but I couldn’t help but be attracted to the ones with the showy flowers. If I had more natural history knowledge of the species I am sure I would have appreciated the community more.

There was one wetland specialist that I recognized though, purple pitcherplant (Sarracenia purpurea). They only grow in highly alkaline or acid environments, places where most plants have trouble acquiring enough nutrients. They make up for it by feasting on insects that are lured into their water-filled leaves.
