Matrix (Connectivity/Diversity Blocks and General Forest Management Area)
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) between Late-Successional Reserves.
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
In the Matrix, there are approximately 55,300 acres of BLM-administered land in the General Forest Management Area and 6,600 acres in Connectivity/Diversity Blocks. Connectivity/Diversity Blocks vary in size and are distributed throughout the Matrix (see Map 3).
Apply the management actions/direction in the Special Status and SEIS Special Attention Species and Habitat 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 and in the Timber section.
Provide a renewable supply of large down logs well distributed across the Matrix landscape in a manner that meets the needs of species and provides for ecological functions. Models will be developed for groups of plant associations and stand types that can be used as a baseline for developing prescriptions.
Retain green trees and snags throughout the General Forest Management Area as follows:
Provide Connectivity/Diversity Blocks spaced throughout the Matrix. Manage the blocks as follows:
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.
Conform all management activities within the range of Port-Orford cedar to the guidelines described in the BLM Port-Orford Cedar Management Guidelines to mitigate damage caused by Phytophthora lateralis. Site-specific analysis for projects within the range of Port-Orford cedar will consider possible effects on the species.
