A calcareous fen is a natural community where groundwater seeping through a calcareous substrate (in this case, a gravelly glacial moraine) rises to the surface creating a unique, nutrient-poor wetland community of very interesting plant species. They are often referred to as a "hybrid" community since the plant association is an odd combination of plants from communities as divergent as bogs on the wet end to dry prairies on the dry end. It is very strange to see a pitcher plant growing near to Little Bluestem Grass, a plant typical of dry prairies. The pH is usually neutral or alkaline, and many of the plants are calciphiles.
The substrate in this fen is a combination of gravel, marl, muck and peat, and it is very soupy in places where one will sink into the mire. This fen is also a good example of what is called a "perched fen" or "hanging fen" because there is a distinct slope where the water emerges at a much higher level than the nearby river. The tall, large-leaved plant with yellow flowers is Prairie Dock (Silphium terebinthinaceum).
These photos were taken with a 10-24mm Nikkor lens (the equivalent of a 15-36mm on my camera). This was my first opportunity to use it, and I think I'm going to like it for landscape-style natural community shots.

Orchid substrate and aquarium charcoal should work, right? My hope is that they will help retain water and prevent fungus growth, plus I happened to have both in the house.
I thought about not using a backing board, but a) I don't want the cover to be floppy, that's one of my annoyances from the official Smart Cover; and b) there needs to be a substrate in which to hide the magnets.

Much of the substrate derives from demolition of air base buiidings and from excavated roads near the old runway. This plover was in a small party of eight which were remarkably tolerant of people, their dogs and bikes passing on a gravel track, nearby.

Advancing and receding contact angles are readily determined by inclining the substrate and allowing the drop to deform as a function of gravity. By mounting a ramé-hart goniometer on the optional Automated Tilting Base, it is possible to incline not only the substrate but the entire instrument, preserving perfectly the optics-to-specimen alignment. This technique greatly expedites such measurements. The Automated Tilting Base is fully software driven and is supported by DROPimage Advanced v2.3 and above. This option requires DROPimage Advanced.
