Water and Soils
As directed by the Clean Water Act, comply with state water quality requirements to restore and maintain water quality to protect the recognized beneficial uses in district watersheds.
Improve and/or maintain soil productivity.
Land Use Allocations
None specifically for water quality or soils. However, Riparian Reserves, Key Watershed provisions, and Timber Production Capability Classifications will assist in meeting water quality and soils management objectives.
Improve and/or maintain soil and water conditions by closing selected areas to vehicle use and/or limiting such use to existing or designated roads and trails. See Recreation, Off-Highway Vehicle Areas, and Roads sections for additional details.
Continue to implement a nonpoint source management program in cooperation with the U.S. Environmental Protection Agency and the Oregon Department of Environmental Quality.
Continue coordination with the Oregon Department of Environmental Quality for implementation of best management practices which protect beneficial uses of water.
Ensure consistency of management activities with the Oregon Water Management Program for forest practices and with Oregon's water quality criteria and guidelines (Oregon Administrative Rule 340-41).
Protect flood plains and wetlands in accordance with Executive Orders 11988 and 11990 and the Riparian-Wetlands Initiative for the 1990s. Design and implement watershed restoration projects that promote long-term ecological integrity of ecosystems, conserve the genetic integrity of native species, and attain Aquatic Conservation Strategy objectives. See Aquatic Conservation Strategy for additional guidance.
Cooperate with federal, state, local, and tribal agencies and private landowners to develop watershed-based coordinated resource management plans or other cooperative agreements to meet Aquatic Conservation Strategy objectives.
Prevent watershed degradation rather than using mitigation or planned restoration to correct foreseeable problems caused by management activities.
See best management practices in appendix C for additional guidance.
Identify and attempt to obtain instream flows needed to maintain riparian resources, channel conditions, aquatic habitat, and water quality.
Locate water drafting sites to minimize adverse effects on stream channel stability, sedimentation, and instream flows needed to maintain riparian resources, channel conditions and fish habitat.
Apply herbicides, insecticides, and other chemicals in a manner that avoids impacts that retard or prevent attainment of Aquatic Conservation Strategy objectives.
Use land acquisition, exchange, and conservation easements to meet Aquatic Conservation Strategy objectives.
Apply for water rights to support the needs for fire suppression, construction/maintenance (e.g., pump chances, water holes, and reservoirs) and other programs as appropriate.
Apply best management practices during all ground- and vegetation-disturbing activities. See appendix C for a list of practices.
Minimize disturbance of identified fragile sites.
Appendix C includes a summary of management guidance for fragile sites.
When aerial or cable systems are used, suspend one or both ends of logs above the ground for all or part of their length during most of the yarding operation.
In timber sale areas involving ground yarding systems, use existing skid trails as much as possible. As a general rule, limit new skid trails to slopes less than 35 percent and limit tractor operation on skid trails to periods of low soil moisture content when resistance to soil compaction is greater. Require operators to minimize the extent of soil displacement during logging. At the time of regeneration harvest, till compacted areas with a properly designed, self-drafting winged subsoiler. For entries other than regeneration harvest, consider tilling skid trails with the same equipment where it can be done with minimum damage to roots of reserve trees.
During site preparation, avoid using prescribed fire on soils recognized as unusually erodible, nutrient deficient, or low in organic matter. On other soils, design prescriptions to protect beneficial soil properties (e.g., prescribed fires of low and moderate intensity). As a general rule, conduct burning operations when large fuels are moist and small fuels are dry.
Use the following guidelines for mechanical site preparation:
