Sustainable Capacity in Value, Biomass Carbon - What Models provide.

摘要

Research in inventory, growth models and planning systems peaked between 1980 to 2000. Meanwhile, requirements for precise yield projections have increased for value, biomass and carbon. This paper presents new, integrated models and strategies for assessing sustainable capacity at stand, forest and region levels. New, integrated approaches to inventory design, growth models and planning systems provide insight into native growth capacity, climate impacts and species dynamics not previously observed.These findings identify more robust approaches to field research designs, technology integration and forest-wide planning. A universal modeling system is described which provides more precise yield projections across all silvicultural systems (clearcut,seed-tree, shelterwood, selection). This universal model has been calibrated for tree species in all major forested regions of the country. It provides a means to evaluate carbon capacity and flow at the stand, forest, region and national levels.
