I recently hiked into the Buncom Roadless Area to review the tree removal mark in units 14-30 and 15-30 of the Nedsbar Timber Sale.
|The large Douglas fir trees in this photo are marked white for removal in logging operations. Trees up to 30" diameter are marked in unit 14-30.|
Unit 14-30 is located on the dark, north-facing slope of a small mountain I call "Silk Tassel Butte." This small hump of a mountain extends off the lower end of Cinnabar Ridge just before it crashes down towards the confluence of the Upper and Little Applegate Valley.
Unit 14-30 overlooks the lower end of the Little Applegate Valley, and even from the valley bottom, the forest stands out as an isolated late-seral stand of Douglas fir and ponderosa pine. The forest is broken by vertical strips of oak woodland and chaparral. Some of the most extensive silk tassel (Garrya fremontii) stands in the region colonize the mountain's south-facing slope, along with buckbrush, manzanita and white oak.
Over one-half mile of new road construction within the Buncom Roadless Area would be necessary to access unit 14-30. The BLM is proposing to build new road up from the Little Applegate Valley to a low saddle west of unit 14-30, then across the steep north face of the mountain. The new road would require a rather large footprint due to the steepness of terrain. Two new helicopter landings would also be created to facilitate commercial logging.
The unit is proposed for a Selective Thinning-Douglas fir prescription. The prescription proposes to maintain 40%-50% canopy cover following logging operations. The canopy cover targets in this unit are necessitating the removal of many large, fire-resistant Douglas fir trees.
Currently the stand is relatively open spaced and spacious with very little understory fuel. Fuel loading in the unit is minimal with the mature forest canopy suppressing understory growth. Directly adjacent to the unit is a small section of land previously logged by the BLM. These logged stands, adjacent to unit 14-30, have dense understory fuel and compromised forest canopies; the result has been a dramatic increase in flashy understory fuel and an increase in overstory mortailty. The prescription proposed for unit 14-30 would create similar results, increasing fire hazards in the area and removing large, fire-resistant trees.

The western half of the unit, much of which is located in a small draw, is proposed for tractor yarding, meaning soil disturbance and compaction will be significant. Noxious weeds will likely spread in the tractor treads and the dragging of large logs through the stand will pierce through the soil, disturbing a large portion of the unit. The soil disturbance associated with tractor yarding has also been shown to increase reproduction of woody understory species, creating a dramatic increase in fuel loads.

The BLM has identified the unit as about half dispersal and half roosting and foraging habitat for the northern spotted owl. The removal of large, old trees and the heavy reduction in canopy cover will impact northern spotted owl habitat, likely downgrading or eliminating habitat conditions necessary for the owl. BLM stand data claims the stand is between 100-150 years old, yet many trees older than 150 years are present throughout the stand. Some of these trees are marked for removal.
The eastern portion of the unit would be helicopter logged, requiring two new and large helicopter landings, one at the western edge of the stand and one directly at the center of the unit. Helicopter logging will require the removal of large wildlife snags within the unit to facilitate worker safety. Helicopter yarding will also impact wildlife and local residents with substantial noise disturbance during the operational period.
Unit 14-30 is unroaded and wild, a fragment of late-seral forest surrounded by non-forest plant communities and young conifer stands. The unit represents the most fire-resilient landscape in the immediate vicinity, as well as the most important habitat for the northern spotted owl and thermal cover for local wildlife species. Building new road and logging this stand to 40%-50% canopy cover will impact the area's unroaded character, reduce its resilience to natural disturbances (e.g. fire and insect infestation), downgrade northern spotted owl habitat conditions, reduce thermal cover for local ungulates, and increase fuel loads adjacent to rural homes in the Little Applegate Valley. Unit 14-30 should be canceled.
Unit 15-30 lies on the western face of Cinnabar Ridge, directly above the intersection of Eastside Road and Upper Applegate Road. The unit is located within the Buncom Roadless Area on a brushy west-facing slope of silk tassel, buckbrush, manzanita, and patches of white oak. The arid soils support nearly all "non-forest" plant communities in a diverse patchwork predicated by solar exposure, slope position, soils, and fire history. The area burned in 1987 and behaved much like a fire would be expected to given the droughty conditions and generally scrubby plant communities.
Much of the chaparral burned at high severity, as it naturally does, and has regenerated into a vigorous community of stump-sprouting silk tassel and patches of chaparral that sprouted from the soil's seed bank after the fire. The community is naturally resilient to fire; its strategy is to grow quickly following fire on poor sites, colonizing the space opened by high severity fire and limited by exposure. The chaparral community mingles with stands of white oak, some that burned off in the fire and are now sprouting into multi-stemmed trees, and stands where the fire dropped to the ground and left the oak canopy unscathed.
The fire also dropped to the ground in Nedsbar Timber Sale unit 15-30, an isolated conifer habitat on the north slope of a low spur ridge. Surrounded by chaparral and a natural high severity fire regime, the stand appears to have sustained very little mortality in the 1987 fire — burning in the understory, clearing out small patches of brushy fuel and maintaining a canopy of large old trees.
|Open forest in unit 15-30.|
Seventy-one fire resilient trees between 20" and 26" in diameter are marked for removal in unit 15-30. Nearly all these trees are in the top half of the 17-acre unit. The upper portion of unit 15-30 is a model for fire resiliency in the brushy foothills of the Applegate Valley. Unit 15-30 has survived recent fires and maintained consistently low fuel loads.
Currently, the upper portion of the stand does not need any fuel reduction and canopy removal will only increase fuel hazards and understory fuel loads. Canopy removal will increase sunlight to the forest floor and the dense brushy fuels surrounding the unit will move in from the edges, creating a contiguous and highly flammable layer of woody understory vegetation.
Canopy reduction in this stand will shift the fuel dynamics from equilibrium and fire resiliency, from an understory, low severity fire regime, to a chaparral ecology of high severity fire. The diversity of the Applegate Valley foothills is one of complex patch mosaics, abrupt edge effects, and a kaleidoscope of intertwined but distinctive plant communities. This mosaic can easily be converted to homogenous chaparral fuels, especially when fire resilient vegetation types are not maintained.
The stand provides a model of healthy, fire-adapted forest conditions in the Applegate foothills. These conditions should be maintained on the landscape by deferring treatment of unit 15-30. The unit should be canceled from the Nedsbar Timber Sale.
