PORT ANGELES — The evidence of effects of wolf eradication on Olympic National Park’s river systems will be the topic of a lecture on Jan. 8.
The lecture is part of the park’s Perspectives Winter Speaker Series, which is offered free at 7 p.m. on the second Tuesday of each month. The talks are in the Raymond Carver Room of the Port Angeles Library, 2210 S. Peabody St.
“Wolves, Elk, Rivers and Trophic Cascades in Olympic National Park” will be presented by Kurt Jenkins, PhD, wildlife biologist with the United States Geological Survey
This presentation explores evidence of possible ecological effects on the park’s riverine ecosystems as a result of wolf eradication nearly a century ago.
The series is sponsored by Olympic National Park, the Friends of Olympic National Park and the North Olympic Library System.
“We invite our neighbors and visitors to see Olympic National Park through new perspectives,” said Olympic National Park Superintendent Sarah Creachbaum.
“Science, research and collaboration provide new windows on the park and are all featured in this year’s series.”
