The Chetco River near Redwood Bar |
The Chetco River is one of the wildest, most spectacular and most diverse rivers in the West. In fact, 66% of the Chetco River watershed flows through remote wilderness and roadless backcountry. The fisheries and water quality of the Chetco River are fed by the countless wild streams flowing through the Kalmiopsis Wilderness and the surrounding wildlands. The fisheries of the Chetco River are among the most important on the Oregon Coast and they are currently threatened by post-fire logging on both private and federal land.
In contrast to much of the river basin, the lower Chetco River near Brookings, Oregon is far from pristine. In many locations, private timber interests and federal land managers have scalped whole mountainsides, and in some cases, whole watersheds of old-growth timber. The result has been high road densities, vast plantation forests, and simplified ecosystems highly susceptible to stand-replacing fire. The lower Chetco River once contained intact, old forests of coastal Douglas fir, Port Orford-cedar and western hemlock. Portions of the watershed support the northern-most stands of coastal redwood, much of which was logged off decades ago; however, a few remnant stands of redwood forest still remain in the Chetco Watershed.

This past summer the Chetco Bar Fire burned throughout the Chetco River canyon from deep in the Kalmiopsis Wilderness to within five miles of Brookings, Oregon. The fire burned in a diverse fire mosaic, burning slowly and at relatively low severity for the first month and a half of the fire. On August 15, 2017, under the influence of strong "Chetco Effect" winds and extremely low relative humidity, the fire surged to the west, quickly burning roughly 95,000 acres in one week of extreme fire weather. Under these conditions the fire burned through plantation stands, old-growth forests and snag fields from the 2002 Biscuit Fire. The winds and low relatively humidity largely overrode fuel loading as the main driver of fire severity in the Chetco Bar Fire. As the fire approached the coastal portions of the watershed stand structure did influence fire severity to some degree, and plantation stands did contribute to the level of mortality sustained during the Chetco Bar Fire. At the same time, the canyon's remnant old stands and scattered old trees sustained less mortality than the surrounding plantation stands.
Fire severity was highest on the ridges and mid-slope, where the fire could build some steam and was most influenced by wind and solar radiation. In the river canyon fire severity was reduced by natural vegetative conditions, higher levels of humidity and less exposure to heavy winds. Although portions of the lower Chetco River canyon burned hot, other portions burned at low to moderate severity, maintaining canopy conditions and burning understory fuel.
The Chetco River Watershed Assessment documents increased surface erosion rates, sedimentation and water quality impacts associated with heavy industrial logging and road building in the river's lower reach. Tributary streams such as Basin Creek, Eagle Creek, the Mineral Hill Fork, and Quail Prairie Creek have been heavily logged and heavily impacted by industrial land management practices. These watersheds are now being targeted for post-fire logging by the Rogue River-Siskiyou National Forest in the 13,626-acre Chetco Bar Fire Salvage Project.
Many people are claiming that because the lands targeted for post-fire logging are "matrix lands" designated for commercial logging, the project's impact will be reduced. Yet, the scale of logging and plantation development proposed will significantly alter forest structure, increase fuel loading, reduce fire resilience, impact the natural fire regeneration process, and degrade water quality in the Wild & Scenic Chetco River.
Others are also claiming the impacts will be minimized because the project will log only plantation stands and forests that burned at high severity. These claims are only partially true. It is true that large areas of plantation forest did burn on federal land, but recent GIS analysis shows that only 33% of the acres proposed for post-fire logging have been previously logged. It is also true that fire severity in these stands is variable, with some stands totally torching and others burning in a mixed-severity fire mosaic. Many of the plantation stands benefited greatly from the Chetco Bar Fire, which punched holes in the unnaturally uniform stands, reduced stand density and created a more diverse mosaic from the once evenly spaced and even-aged plantation stands.
Natural, unmanaged stands and some stands that were previously selectively logged are also proposed for post-fire logging. The Forest Service is proposing to log all stands located within "matrix" lands that sustained between 50% and 100% mortality in the Chetco Bar Fire. This means that some stands that survived the fire with only 50% mortality will be logged, contradicting the claim that only severely burned stands will be harvested.

Surface erosion and sedimentation will significantly increase due to soil disturbance and vegetation loss associated with logging. Stream shade from both standing snags and living green trees will be reduced, impacting stream temperatures. The effects of clearcut logging will increase forest fragmentation and impact forest connectivity. Large old snags and living trees will be removed, reducing forest complexity and coarse woody debris recruitment. Slopes will be cleared, the fire mosaic degraded and vast interconnected areas converted into new tree plantations. The logging has severe impacts, but the plantation development will also degrade habitat conditions for many, many years to come.

Plantation stands are broadly acknowledged as biological deserts with little stand complexity or habitat value. They are also the most flammable portions of the landscape. If the Forest Service moves forward with the Chetco Bar Fire Salvage Project, they will be creating the forest health and fuel problems of the future.
The lower Chetco River is currently a mixture of extreme beauty and industrial devastation. We should demand more for this important watershed. Stop the Chetco Bar Fire Salvage Project!
