Non-native or invasive species are widespread throughout the landscape; some have detrimental effect to diverse habitats. What “tools” do we have in the toolbox to fight these invaders? How can we utilize biological control agents to help us? The MidCoast Watersheds Council invites the public to attend a presentation on invasive species control on September 6th, 2018 at 6:30 PM in Newport.  The meeting will be held in room 205 (upstairs) at the Newport Visual Arts Center at Nye Beach.  Refreshments will be served.

Non-native plants are all around us. Some are beneficial to us; while others are potentially harmful. Jim Nechols, an insect biologist and retired professor from Kansas State University, specializes in ecology and biological control of insect pests and weeds. Biological control is the control of a pest species by the introduction of a natural enemy or predator. Jim will share a presentation on what causes non-native species to be a nuisance and what we can do to manage these invasive species. Jim will also discuss biological control on knotweed species, a common riparian invader along the coast that is very difficult to control without chemical application.

Come learn more about efforts to control non-native species, and what you can do to help us in our fight! We hope to see you on Thursday, September 6th at the Newport VAC.

Knotweed, both Japanese and Giant species, can choke out all native vegetation in riparian areas, and spreads quickly downstream. Above, a youth crew member shows the size that knotweed plants can reach.
