20. For each of the following categories, name one animal that you would expect to find in an Ozark cave: a) troglobite, b) troglophile, and c) trogloxene. (3 pt)
21. The riparian zone of Wilson’s Creek is believed to contain several unmarked grave sites.

Assuming that the watershed is currently forested, describe the impacts that this development would have on the stream. (Provide a topographic map with a highlighted area.) (5 pt)
23. Early settlers of the Ozarks established home sites near springs such as the one near the Ray House. A power company plans to build a power generation plant in the recharge zone of Ray Spring. The plant will require three 800-foot wells for the cooling towers. What potential effect will this have on the spring? Explain, and propose some mitigation options. (5 pt)
