Application of the Forest Vegetation Simulator in evaluating management for old-growth characteristics in southwestern mixed conifer forests

Abstract

We used the Forest Vegetation Simulator (FVS) and GRAFM graphics display to investigate conditions associated with the stability of an old-growth stand and to evaluate the potential for two managed stands of contrasting but representative conditions to develop structures similar to the old-growth stand. Simulations indicate that the example old-growth stand can retain old-growth characteristics for up to 100 years in the absence of catastrophic disturbance. Modeling also indicated that silvicultural intervention could enhance the future old-growth potential of the two managed stands.
