Matrix (General Forest Management Area) - West Side
The Matrix, or General Forest Management Area, on the west side, totals approximately 23,550 acres. Included in the Matrix are approximately 2,300 acres of buffers around the District Designated Reserves (Late-Successional/District Designated Reserve buffers). Management direction for the Late-Successional/District Designated Reserve buffer lands is more restrictive than for the other matrix lands, and is described separately. The Matrix in the Klamath Falls Resource Area is designed to provide connectivity and biological diversity across the landscape rather than in large connectivity/diversity blocks.
Produce a sustainable supply of timber and other forest commodities to provide jobs and contribute to community stability.
Provide connectivity (along with other allocations such as Riparian Reserves) across the landscape for forest dependent plant and animal species.
Provide habitat for a variety of organisms associated with both late-successional and younger forests.
Provide for important ecological functions such as dispersal of organisms, carryover of some species from one stand to the next, and maintenance of ecologically valuable structural components such as down logs, snags, and large trees.
Provide early-successional habitat.
Land Use Allocation
There are approximately 23,550 acres of BLM-administered land in the Matrix (General Forest Management Area) on the west side.
Apply the management actions/direction in the Special Status and Supplemental Environmental Impact Statement Special Attention Species section. Conduct timber harvest and other silvicultural activities in that portion of the Matrix with suitable forest lands, according to management actions/ direction summarized below, the Timber section, and Appendix E.
A portion of BLM-administered forest lands will be available for maintenance of biological diversity, including old growth characteristics, and will not be subject to planned timber harvest. These forest lands include: nonsuitable woodlands, suitable woodlands-all categories, recreation sites, forest lands allocated for riparian-wetland area protection in Riparian Reserves, proposed areas of critical environmental concern and research natural areas, core areas around bald eagle and spotted owl nest sites, and other areas required for threatened and endangered species recovery. These forest lands total approximately 24,050 acres, of which 6,600 acres are currently old growth and 6,100 acres are mature forest.
Designate the Klamath Canyon an Area of Critical Environmental Concern (see the Special Areas section) and manage for old growth and diversity of native plant communities, as well as for historic, cultural, scenic, fisheries, and wildlife populations.
Manage the 23,550 acres of Matrix forest lands under uneven-age/multiple canopy management harvest prescriptions (see the Timber section). These forest lands will allow for migration and dispersal of organisms between the Late-Successional Reserves on U.S. Forest Service land to the north and the Klamath Canyon to the south (see Maps 3 and 4 in the map packet).
Provide a renewable supply of large down logs well manner that meets the needs of species and provides for ecological functions. Down logs will reflect the species mix of the original stand. Models will be developed for groups of plant associations and stand types that can be used as a baseline for developing prescriptions.
Modify site treatment practices, particularly the use of fire and pesticides, and modify harvest methods to minimize soil and litter disturbance. Plan and implement treatments to:
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 100 acres of the best northern spotted owl habitat as close as possible to a nest site or owl activity center for all known (as of January 1, 1994) spotted owl activity centers.
