The Secret Life of Rivers
April 22, 2020 @ 5:00 pm - 6:30 pm
The Coalition for the Deschutes and Deschutes Redbands Chapter of Trout Unlimited would like to invite you to join via Zoom for a presentation with the entertaining, edifying, and endearing aquatic ecologist, Dr. Jerry Freilich.
Rivers are like eyeglasses. Glasses appear transparent and utterly simple, yet the subtle curves of a lens 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 rivers are so important to the basins they drain.
When: Wednesday, April 22nd, 5:00 – 6:30 pm, including time for Q & A
Via Zoom. Join the meeting here:
Who the heck is this Jerry guy?
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. Jerry’s PhD work was a study of salmonflies at Grand Teton National Park. The work required individually tagging 3,000 salmonfly nymphs with tiny numbered tags and following their movements about in the river. Although this gave him the microscopic-eye view of river ecology, he warns not to try this at home.
