Info

We know very little, in some cases nothing, of the role forest insects and diseases play in the management of young forests of seedlings, saplings, and pole- sized trees in the northern Rocky Mountains. If we wish to minimize damage and losses caused by these agents in young coniferous stands, where much of our forest management effort is directed, more research must be devoted to the study of the biology, ecology, and impacts of insects and diseases affecting forest regeneration.
