Provide a sustainable supply of timber and other forest products while maintaining a healthy, functioning ecosystem.
Manage developing stands on available lands to promote tree survival and growth and to achieve a balance between wood volume production, quality of wood, and timber value at harvest.
Manage timber stands to reduce the risk of stand loss from fires, animals, insects, and diseases.
Provide for salvage harvest of timber killed or damaged by events such as wildfire, windstorms, insects, or disease, consistent with management objectives for other resources.
Land Use Allocations
The general forest management area lands are available for restricted timber production only (see also Table 1 in Appendix B). Restricted timber production refers to management of forest stands for purposes other than intensive commodity production, such as development of old growth habitat, visual quality, or ecosystem stability and maintenance.
Matrix (General Forest Management Area) - West and East Sides
Declare an annual allowable sale quantity of 1.03 million cubic feet on the west side and 0.08 million cubic feet on the east side of the Klamath Falls Resource Area.
The allowable sale quantity for the resource management plan is an estimate of annual average timber sale volume likely to be achieved from lands allocated to planned, sustainable harvest. Harvest of this approximate volume of timber is considered sustainable over the long term. This is based on assumptions that the available land base remains fixed, and that funding is sufficient to make planned investments in timely reforestation, plantation maintenance, thinning, genetic selection, forest fertilization, timber sale planning, related forest resource protection, and monitoring.
The allowable sale quantity represents neither a minimum level that must be met nor a maximum level that cannot be exceeded. It is an approximation because of the difficulty associated with predicting actual timber sale levels over the next decade, given the complex nature of many of the management actions/directions. It represents BLM's best assessment of the average amount likely to be awarded annually in the planning area over the life of the plan, following a start-up period. The actual sustainable timber sale level attributable to the land use allocations and management direction of the resource management plan may deviate by as much as 40 percent from the identified allowable sale quantity. As inventory, watershed analysis, and site-specific planning proceed in conformance with that management direction, the knowledge gained will permit refinement of the allowable sale quantity. The separable component of the allowable sale quantity attributable to lands in key watersheds carries a higher level of uncertainty, due to the greater constraints of Aquatic Conservation Strategy objectives and the requirement to prepare watershed analyses before activities can take place.
During the first several years, the annual allowable sale quantity will not likely be offered for sale. The resource management plan represents a new forest management strategy. Time will be required to develop new timber sales that conform to the resource management plan.
Maintain a well distributed pattern of early and mid-seral forest across the Matrix.
Apply silvicultural systems that are planned to produce, over time, forests which have desired species composition, structural characteristics, and distribution of seral or age classes (see Appendix E).
Develop plans for the locations and specific designs of timber harvests and other silvicultural treatments within the framework of watershed analyses (see Appendix E).
Select logging systems based on the suitability and economic efficiency of each system for the successful implementation of the silvicultural prescription, for protection of soil and water quality, and for meeting other land use objectives.
Base silvicultural treatments and harvest designs on the functional characteristics of the ecosystem and on the characteristics of each forest stand and site. Treatments will be designed, as much as possible, to prevent the development of undesirable species composition, species dominance, or other stand characteristics. The principles of integrated pest management and integrated vegetation management will be employed to avoid the need for direct treatments. Herbicides will be used only as a last resort.
Unscheduled Harvests. Manage suitable and nonsuitable woodlands (all categories) for resource values other than sustained timber production. Other forest lands not subject to planned harvest include existing high-use recreation sites, riparian-wetland areas, Mountain Lakes Wilderness Study Area, proposed area of critical environmental concern, an area adjacent to the Pacific Crest Trail, bald eagle and peregrine falcon nest site protection areas, and identified cultural sites. Plan unscheduled harvest to manipulate stand density, composition, fuel loads, or other features where the resulting stand will improve forest ecological condition, wildlife habitat, or other resource values. Specifically, plan harvest of marketable western juniper woodlands for improvement of forest or range land ecosystem or watershed conditions. Up to 1,000 acres per year of juniper woodland could be harvested for commercial forest products. See also Riparian Reserves and Late-Successional/District Designated Reserves sections.
Apply the management actions/direction in the Riparian Reserves, Late-Successional/District Designated Reserves, and Special Status and Supplemental Environmental Impact Statement Special Attention Species section. Appendix E describes the silvicultural systems to be applied to available forest lands.
On the east side, retain 5 to 10 of the largest (greater than 16 inches diameter at breast height) and healthiest green trees per acre. In addition, maintain a sustainable uneven-aged understory so that there is a variety of different sized trees and species represented throughout the stand available for recruitment.
On the west side, retain 16 to 25 large green trees per acre in harvest units.
Retain late-successional forest patches in landscape areas where little late-successional forest persists. This management action/direction will be applied in fifth field watersheds (20 to 200 square miles) in which federal forest lands are currently comprised of 15 percent or less late-successional forest. (The assessment of 15 percent will include all federal land allocations in a watershed.) Within such an area, protect all remaining late-successional forest stands. Protection of these stands could be modified in the future when other portions of a watershed have recovered to the point where they could replace the ecological roles of these stands.
Retain snags within a timber harvest unit at levels sufficient to support species of cavity-nesting birds at 60 percent of potential population levels. Meet the 60 percent minimum throughout the Matrix with per acre requirements met on average areas no larger than 40 acres.
On the west side, leave 120 linear feet of logs per acre greater than or equal to 16 inches in diameter and 16 feet long. On the east side, leave 50 lineal feet of logs per acre greater than or equal to 12 inches in diameter and 8 feet long. Existing decay class 1 and 2 logs count toward this requirement. Down logs will reflect the species mix of original stands. Where this management action/direction cannot be met with existing coarse woody debris, merchantable material will be used to make up the deficit.
Within identified sensitive rural interface areas, alter forest management practices, where realistically feasible, to mitigate adjacent landowner concerns. Practices used will be consistent with sustained yield.
Special Habitats. In project areas containing special wildlife habitats (for example, talus and meadows) maintain 100 to 200 foot buffers around the special habitat. This could be increased, decreased, or manipulated based on site-specific circumstances. Ecologically significant buffers will be determined by interdisciplinary teams.
