Lynwood Gill (center), Craig Blencoe (second from right) and Mandy Boros (left of center) lead a field trip on sustainable forestry on March 1, 2002 as part of the Salmonid Restoration Federation Conference. This photo shows opening remarks near entrance to the Parker Ranch on which the field trip was held. Rocky soils in the slopes in the back ground make them hardwood dominated. Photo by Pat Higgins.
Looking south from entrance to Parker Ranch at ridge recently harvested with 20% of standing timber removed. Skyline cable corridor visible on crest of ridge at center of photo. This steepness of slopes in the picture (i.e., the area in shadow) would make slope failure risk high had this sight been clear cut. Logs can be suspended with little ground disturbance for 150 feet perpendicular to the cable on each side. Growth of trees increased 2.6% because harvest of competing trees allows release of growth of those remaining. Re-entry every 15 years with similar methods is planned. Photo by Pat Higgins.
Lynwood Gill addresses field trip attendees on a logging road in an area where timber harvest had taken place the previous year. Note the diverse age of conifers in the picture and the low impact road (narrow width, out sloped with no ditch). Photo by Pat Higgins.
Logging skid trail up to the right has duff to prevent gully and surface erosion. Stump in foreground is evidence of recent timber harvest. Older charred stump indicates previous period of logging. Photo by Pat Higgins.
View of forest two years after harvest. Note that limited ground disturbance and spreading of duff has allowed recovery of skid trails to a vegetated and non-eroding condition. Photo by Pat Higgins.
Lynwood Gill standing on the edge of a road used for log hauling. Note that there is no ditch on the road and that instead it is out sloped. This type of road poses much less risk of failure than ones that have ditches and culverts under the road. There is also no side-cast material from the road bed excavation behind Lynwood. Side casting can change the load on the slope and cause landslides and road failure. Photo by Pat Higgins.
Side view of same location as Picture #6 with view of forest after recent timber harvest. The large stump gives evidence of logging after WW II. Photo provided courtesy of Pat Higgins.
