摘要：Browsing by large ungulate wildlife species damages valuable trees, but increases the productivity of the wildlife stock. The optimal management of trees and wildlife involves a tradeoff between these two impacts, as well as correct timing of tree harvests from each forest stand. For a model of moose and pine in Norway, it is found that harvest of adjacent forest stands should be adjusted over time to bring the stands into synch. Doing so maximizes the moose productivity boost that occurs immediately following harvest of mature trees, and protects the young trees from overbrowsing by spreading out the browsing pressure among more young trees. This result is, however, sensitive to the specification of the relationship between forage availability and moose productivity.
