Juday Creek, South Bend, Indiana
Clear water is an unusual phenomenon in northern Indiana, but this stream flows clear even after heavy rains. It is my hope that landscape developers will do more to preserve and restore the natural features of the land in and around their projects, allowing water to move gradually through natural areas, being cleaned as it percolates through soil. Then it could seep into attractive, meandering streams instead of being shunted immediately to mud-walled ditches and fouling everything downstream with silt and chemicals. If we truly had clean, oxygen-rich water in our rivers, lakes, streams, and wetlands, our quality of life would be improved dramatically, and our fish, wildlife, and native plant life would be much more diverse. Special thanks to the many people who work to keep Juday Creek clean and intact!

Walking Fern and Pinnatifid Spleenwort
The magnificent rock cliffs and canyons of central Indiana support a nice variety of pteridophytes. Walking Fern, shown below, grows on damp rock walls and fallen boulders, especially where it's mossy. It's called "walking fern" because sometimes it gets up and moves around to find a more suitable place to grow! OK, that's not true, but it does have a pretty cool trick. The long-attenuate blades take root at the tip and new plants sprout - an excellent form of vegetative reproduction. Sometimes the tips are not touching the substrate, but little plantlets grow and eventually fall off, spreading the fern to new locations.
Camptosorus rhizophyllus, or Asplenium rhizophyllum, Walking Fern
A rare hybrid of Walking Fern and Ebony Spleenwort is called Pinnatifid Spleenwort, Asplenium pinnatifidum. It sometimes shows up on a damp rock shelf beneath an overhanging outcrop.
