Forest and Rangeland Resource
A supporting technical document to the 1989 RPA
Information on resource interactions has been identified as an essential
component of national resource assessments. The term Aresource interactions" simply
refers to the mutual influence (in production) that different forest and rangeland
resources have upon each other. Forest and rangeland resources are interactive in
production because they share or are simultaneously affected by common labor, land,
capital, and managerial inputs. The estimation of resource interactions has proved to be
very complex, especially where many resource outputs are involved over a large geographic
This paper presents an analysis of resource interactions on the National Forest System
lands, based on information developed in the forest planning process. Three questions were
1. What trends in costs are implied for simultaneously maintaining current production
levels of all resources and environmental conditions on the National Forest System?
2. If the National Forest System were to maintain a constant share of total national
resource production, would the demand projections developed for individual resources in
other recent assessment analyses be simultaneously achievable?
3. If an attempt were to be made for the National Forest System to maintain a constant
proportion of these demand projections, what would the impacts be on cost trends and
The results indicated that current levels of production and environmental conditions can
be simultaneously maintained at current levels of cost in the National Forest System.
However, this conclusion is limited to the particular outputs and environmental indicators
included in the study. Within the range of alternatives generated in forest planning, it
does not appear to be feasible for the National Forest System to maintain a constant
proportion of national production, if that national production is to simultaneously meet
the projected demands in individual resource analyses. It is impossible to determine
whether this reflects true physical limitations to production or the limits of the forest
