Leader: Ester McEvoy

Tuesday, July 26th, 9:00 am – afternoon
Field Trip: Fairview Peak
Leaders: Bruce Waugh and Dan Luoma
Meet at 9:00 am at the Wilkinson parking lot across from the Beanery. From the parking lot, the drive to the top of Fairview Peak is forty miles.
As an ecotone that connects western and southern Oregon floras, Fairview Peak has some of the most diverse botanizing in the central Cascades, all accessible by car. This trip will sample the variety by making a series of stops with short walks along the road on the way to the nearly 6,000-foot summit. Only experienced drivers in high clearance vehicles (such as a Subaru Forester or similar) in good condition should attempt this rough, steep, and occasionally scary one lane road. Due to very limited parking, carpooling will be required.
The rewards for the risk are a beautiful drive up the Brice Creek drainage, a stop in the forest on the way up to look for achlorophyllous plants, stunning meadows and rock gardens near the top with a flora that includes east side and southern species, and views from Mt. Hood to Mt. McLoughlin on a clear day. A plant list is available at https// Go to Sites, Lane County, and then Fairview Peak and Bohemia Mountain. It is an all-day trip so bring lunch, water, and sunscreen.
Saturday, July 30th, 9:00 am - 12:00 pm

Leader: Esther McEvoy
Located at Avery House, Avery Park, Corvallis. We need help to finish barking the paths and weed beds. Bring water, gloves, trowel, and energy. Contact Esther for more information at 541-990-0948 or

Leader: Jennifer Lippert
This is a beautiful area to see multiple habitats and high species diversity in an approximately two and one half mile round-trip hike. We'll focus on the large meadow complex that surrounds the lake but may climb up the trail for views and additional species if we have time. Meet at South Eugene High School parking lot (19th and Patterson) at 9:00 am to carpool. Bring lunch, water, hiking boots, sunscreen, and hat. Sign up here.
Saturday, August 6th, 8:00 am – 7:00 pm
Field Trip: Oregon Dunes Restoration
Leaders: Armand Rebishke and Dina Pavlis
Hike the John Dellenback Trail and see what the Siuslaw National Forest is up to with dunes restoration. This area is a “preserve the best” unit, meaning it has an abundance of native dunes plants – adapted to open sand conditions reminiscent of historic dunes conditions before the planting and expansion of European beachgrass, brooms, and other invasive species. We’ll see seashore bluegrass, sand fescue, and bearberry plant associations among other native dunes species. The sand boundary was treated during late summer 2020 by cutting and wiping Scotch broom, spraying European beachgrass, and cutting small shorepines. Meet at South Eugene High School (19th and Patterson Street) at 8:00 am to carpool or at Dellenback Trail parking lot (just south of Eel Creek Campground, ~ eleven miles south of Highway 101 and Highway 38 junctions in Reedsport) at 10:30 am. The hike will be approximately three miles round trip (it is an out and back trail). Sand dunes hiking can be strenuous, windy, and chilly. Bring water, lunch, and sun coverage. Sign up here.

Field Trip: Little Cultus Fen
Leader: Jill Kellogg
We’ll be bushwhacking in and around the fen, watching our step to avoid the special plants we will encounter. Boots for wading are needed. Expect mosquitoes!

The last bit of the drive to the fen is on unpaved roads that are rough at times. The average car can drive it but will benefit by driving slowly. Send an email to with “Little Cultus Fen” in the subject line to indicate your interest. Details will be available when the date is set.
