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.

NPSO 2020 Annual Meeting

May 29 - 31     Spirit Mountain Lodge, Grand Ronde, Oregon

Field Trips

Saturday May 30, 2020    9 a.m. - 4 p.m.                    Field Trip # 32

High Peak/Moon Creek Research Natural Area

Difficulty:     Strenuous  (3-4 miles) - Steep slopes, off trail

Elevation:     200 feet elevation gain

Group Size Limit:     12

Trip Description:     The High Peak/Moon Creek Research Natural Area (RNA) is within the northern portion of the Nestucca River Watershed and is characterized by mature coniferous forest stands. A representative selection of low- to mid-elevation forest associations typical of the northern Oregon Coast Range are found here. Stands in the 80- to 160-year-old age class predominate.

The geologic setting of the RNA owes its origin to the Tillamook Volcanics of the upper middle Eocene. The terrain is rugged with deeply incised drainages.

We will visit the upper sections of the RNA, including an old-growth Douglas fir stand that contains 500-year-old Pseudotsuga menziesii with a western hemlock (Tsuga heterophylla) sub-canopy. Old-growth stands are increasingly uncommon in the northern Oregon Coast Range, and the Moon Creek old-growth stand is the last remaining stand in the area. The few remaining stands of old growth and contiguous late-seral-stage habitat are important for habitat-dependent species with low mobility or small home ranges.

A lovely stand of noble fir (Abies procera) crowns the 2980-foot summit of High Peak. The riparian areas offer a wide variety of trees; tall, medium, and low shrub layers; and delicate understory herbaceous and fern species. Less common plant species include: single-flowered wintergreen (Moneses uniflora), claspleaf twistedstalk (Streptopus amplexifolius), Oregon fetid adder's-tongue (Scoliopus hallii), withered bluegrass (Poa marcida), Phantom orchid (Cephalanthera austiniae), and Fendler's waterleaf (Hydrophyllum fendleri).

Appropriate Clothing and Footwear:     Warm clothing, sturdy boots, hiking poles recommended

Special Considerations:     Bushwhacking on steep slopes with rocks, exposed tree roots, and uneven terrain


Meeting Place and Time:     Trip # 32 leaves at 9 a.m. from Spirit Mountain Lodge entrance. Plan to arrive 30 minutes before departure time to meet your group and arrange carpools.

Driving Miles and Time from Spirit Mountain Lodge:     50 miles, 1.5 hours, 5-8 miles unpaved. Due to some rough roads, high-clearance vehicles are recommended.

Driving Directions:     Trip leaders will provide detailed driving instructions.


Leaders:       Dan Luoma, Joyce Eberhart
