Dr.
Tim Stewart (ISU), accompanied by Mike Sundberg (grad student), gave a
talk on the function of the Park's constructed wetlands last Thursday (left). He also showed
us some aquatic plants, invertebrates, fish, and turtle. Later, they
pull up a net trap from Pond J and emptied
the contents into a bucket. Several fish species and a crayfish (right)
had been collected. 8/21/14 (Wolf. Oesterreich)
