Water and Soils
Meet Aquatic Conservation Strategy Objectives.
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 for the Mid Coast and Willamette basins.
Maintain or improve 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.
Management Actions/Direction for Water
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 that protect beneficial uses of water.
Ensure consistency of management activities with Oregon's Statewide Water Quality Management Plan 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 implement BLM's Riparian-Wetlands Initiative for the 1990s (USDI, BLM 1991a).
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, Appendix C, for additional guidance.
Identify and attempt to obtain in stream 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 in-stream flows needed to maintain riparian resources, channel conditions, and fish habitat.
Apply pesticides and other chemicals only if consistent with the 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), recreation and other programs.
Management Actions/Direction for Soils
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 contains a summary of management guidance for fragile sites.
Utilize silvicultural systems that are capable of maintaining or improving long-term site productivity of soils.
Design logging systems to avoid or minimize adverse impacts to soils.
In forest management activities involving ground-based systems, tractor (skid) trails, including existing trails, it will be planned to have insignificant growth-loss effect from compaction (2 percent or less of any treated unit area compacted after amelioration practices). Existing tractor trails would be used as much as possible and new trails would be limited to slopes less than 35 percent. Operation on these trails would minimize soil displacement and occur when soil moisture content provides the most resistance to compaction. Tractor trails, which could include those from previous entries, would be selectively tilled with a properly designed self-drafting winged subsoiler.
To help achieve the goal of insignificant growth-loss effects from compaction, use the following guidelines when using track-type equipment with a brush blade for mechanical site preparation: (1) restrict use to areas with suitable soil types and slopes less than 35 percent; (2) minimize piling of large woody material; (3) avoid displacing duff layers and topsoil into piles or windrows; (4) limit machine use to one round trip over the same area; and (5) operate at soil moistures that maximize resistance to compaction. A low ground pressure backhoe/loader grapple or other special equipment or techniques that would achieve the same insignificant soil compaction may be used instead of the preceding techniques. All areas compacted during site preparation would be tilled with properly designed equipment.
In most instances, avoid using prescribed fire on highly sensitive soils (those soils recognized as unusually erodible, nutrient deficient, or low organic matter). Any burning on such soils, if considered essential for resource management, would be accomplished under site specific prescriptions to accomplish the resource objectives and minimize adverse impacts on soil properties. On other soils, prescribed fire prescriptions would be designed to protect beneficial soil properties.
