The process of recovery of a clear-cut stand, from the standpoint of fisher habitat, could be accelerated by the following practices:
1. Retaining of an abundance (>= 12.3 trees/ha) of cull grand fir trees for future den logs. The objective would be to have trees at least 45.7 cm dbh that would begin to fall 80-100 years after logging.
2. Retaining at least 54 but no more than 109 metric tons/ha of large-diameter logs. An abundance of logs should aid the recovery of southern red-backed voles, providing prey that fishers may begin to use once the regenerated stand has reached the pole stage.
3. Retaining decks of cull logs and a few slash piles for potential fisher resting sites and for habitat for snowshoe hares. (p. 386)
We currently lack the information needed to develop a conservation plan for fishers in the northern Rockies. Therefore, adequate management of fishers and their habitats may require the adoption of a landscape-based approach. Two advantages of a broader strategy are that it has the ability to maintain the integrity of ecological systems and that it can operate with relatively little information (Hunter 1991). Applying such an approach would require land managers to adopt a long-term large-scale plan (Thompson and Harestad, this volume), one that would mimic natural landscape patterns and processes. This in turn would involve management that would keep certain proportions of a forest in various successional stages, together with a specific frequency distribution of various patch sizes and linkages across the landscape. Such an approach would help insure the viability fo fisher populations within a managed landscape. (p. 387)
