The Secret Life of Rivers
March 21, 2017 @ 6:30 pm - 7:30 pm$2 - $5
Rivers are like eyeglasses. They appear transparent and utterly simple, yet the subtle curves of lenses are anything but simple. Likewise, a river seems like a pipe where water enters the top, runs down a channel, and empties into the sea. What could be simpler?
Actually, the ecology of rivers is complex, concealed, eye-opening and will likely surprise you. This program by Dr. Jerry Freilich will explain how rivers work. How many organisms actually make up the riverine ecosystem? Where do they get their energy? And how many of them have you actually heard of?
With awareness of riverine ecology, you will understand why it is unrealistic to think of a river as pipe and why a river cannot be simply turned on and off like a garden hose without causing great harm to its delicate fabric of life.
Dr. Jerry Freilich is a native of Philadelphia. He worked at the Academy of Natural Sciences there beginning at age 11. He is an aquatic ecologist who spent 25 years working for the National Park Service in six parks nationwide. For the last 13 years he was Research Coordinator at Olympic National Park and recently retired to Bend.
