2020 NPSO Annual Meeting Cancelled

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 should 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.

Trip Description:     The Salmon River Estuary is approximately 2,000 acres, with a tidal influence reaching to River Mile 4. The estuary sits in the middle of the Cascade Head Scenic Research Area and United Nations Biosphere Reserve; the mouth of the river is a Marine Reserve. It forms a bay between two basalt headlands - The Nature Conservancy's Cascade Head Preserve to the north, and Camp Westwind's High Meadow to the south.

The estuary salt marshes were diked in 1960 to exclude salt water to create pastureland. Administered by the U.S. Forest Service, the estuary restoration project began in 1978 with the goals of establishing natural processes by rebuilding native plant communities, controlling erosion, and controlling noxious weeds. Dikes and tide-gates were removed, which allowed salt water to return to the marshes, killing pasture vegetation and allowing native salt marsh plants to reclaim the land naturally. Extensive plantings of native shrubs and trees stabilized the marshland perimeters. Recovery and restoration of wetlands that were modified to support an old amusement park and a trailer park were completed by 2011.

We will visit the two largest restoration projects and discuss what we learned about recovery of the native vegetation and the return of juvenile salmon to the estuary and creeks feeding it.

Appropriate Clothing and Footwear:     Warm clothing, layers, knee-high or other sturdy footwear that can get wet are advised.
