THE CHETCO EFFECT…
The Oregon Society of Soil Scientists is pleased to offer an exciting summer field tour, hosted in cooperation with our friends at the Northwest Forest Soils Council! Spend two days with fellow soils professionals and enthusiasts as we explore diverse landscapes on the Rogue River-Siskiyou National Forest that were impacted by the 2017 Chetco Bar Fire. We’ll hear from members of the Forest’s Burned Area Emergency Response (BAER) Team to learn about how soils are affected by fire and drive watershed response. We’ll also learn how local land managers are responding to a diverse array of resource concerns in the wake of the fire. Potential field topics include soil burn severity mapping, salvage logging, protection of critical infrastructure, management of noxious weeds and rare plant communities, and forest management for insects and disease. And, of course there will be soil profiles! We’ll see unique serpentine-derived soils and associated endemic flora (among others).
Base camp will be at Alfred A. Loeb State Park, along the beautiful Chetco River, just outside of Brookings, Oregon. Camping will be available for the nights of September 11th, 12th, and 13th, with the field tour taking place on the 12th and 13th.
(the “Chetco Effect” is a term used by locals to describe high temperatures, low humidity, and high winds that sometimes result from air masses that surge out of the Great Basin and descend the west slopes of the Cascades, converging in the Brookings area. The Chetco Effect contributed greatly to the rapid growth of the Chetco Bar Fire.)

1230-1300 Site 4 – Low Soil Burn Severity on FSR 1909. Opportunity to observe soil and organic matter conditions and vegetation condition in a low soil burn severity area to compare with observations in moderate and high.
1300-1315 Travel to Site 5 on FSR 1917.
1315-1400 Site 5 – FSR 1917 ridgeline. Biscuit Fire area reburned by Chetco Bar Fire 15 years later. Discussion of Biscuit Fire; observations of soils and vegetation response post-Biscuit and post-Chetco. Scenic view looking into Kalmiopsis Wilderness, if weather permits.
1400-1500 Travel to Site 6 via FSR 1917 to FSR 1376 to FSR 1107. Observe Packer’s Cabin (historic site) along the way; see more salvage and fire effects in the watershed.
1500-1630 Site 6 – Snaketooth Redwood Botanical Area (FSR 1107). Site 6a/6b within walking distance. Observe pre-fire timber thinning units on drive to site (Backbone TS) and how they responded to the Chetco Bar fire.

Site 6b: Redwoods fire resiliency, observation of bole resprouting, revegetation. Observations of soils and vegetation response in undisturbed post-fire condition.
1630-1700 Travel back to Loeb State Park. Upon return, may discuss and look at point bar geology on the Chetco River for those interested. Cool off in the water!

0730-0800 Gather,briefing on day’s agenda. Load into vans.

0900-1000 Site 1 – Peridotite/Serpentine Biscuit and Chetco burn effects. Roadcuts to observe geology and soil development; roadcut seep to observe groundwater effects to serpentine rock; Darlingtonia; burned area to look at effects of fire to serpentine soils and upland vegetation community.
1000-1030 Travel to Site 2, FSR 1376. If weather allows clear views, can stop along the way to discuss different geologies of neighboring peaks, how geology affects landforms, etc. Stop at or point out different outcrops along the way.
