May 28-31, 2020 Cancelled
Annual Meeting
Due to the COVID-19 pandemic, and in the best interests for the health and safety of our members, the Cheahmill Chapter has decided to cancel the Annual Meeting this year. While the number of new cases may decline over the next several weeks and months, subsequent waves of COVID-19 are likely to recur once social distancing is relaxed. We are exploring hosting the meeting next year (2021) at Spirit Mountain Lodge and offering much the same program.

If you have already sent in your registration form and payment, your checks will be shredded. Those whose checks were already deposited will receive a refund.
We look forward to seeing all of you in 2021, hopefully at Spirit Mountain. Please stay safe and healthy through this difficult time.

*Chapter Meeting via Zoom - access questions may be directed to Richard Hilliard, PhD student at Oregon State University, will present, "Investigation of Oregon native plants for remediation of trace metals and organic pollutants in stormwater". He explains, "Stormwater collects dissolved and particle associated pollutants from impervious surfaces and carries these to receiving water bodies, degrading their quality. Pollutants of concern include heavy metals, trace organics, sediments, and nutrients. Bioswales, rain gardens and vegetative buffers are increasingly being used to provide passive treatment of these waters. Inclusion of plants in these systems provides potential for phytoremediation, prevention of erosion, increased soil porosity, and an aesthetic quality against the built environment. However, our lack of fundamental knowledge about treatment provided by plants is preventing good design for these systems. A number of Oregon plants were investigated for potential treatment of copper and zinc, sediments, and nutrients."
*All events statewide have been canceled for the 2020 Native Plant Appreciation Week!
