“…This has been confirmed by simulation studies (e.g. Schulte and Buongiorno 1998). In our view, diameter-limit cutting is distinct from high grading because it requires taking all trees above a particular size, good or bad.…”

The long-term financial and ecological effects of diameter-limit regimes and basal-areadiameter-q-ratio (BDq) regimes were compared by simulation in the case of northern hardwood forests. Varying the cutting cycle between 10 and 20 years had little effect on returns or stand structure. A 28-cm diameter-limit cut gave the highest production and financial returns, and the highest species diversity, but considerably lower size diversity. A 38-cm diameter-limit cut and a heavy BDq selection harvest gave high returns, while maintaining high levels of diversity. On lands of equal site quality, Michigan's stands were more productive than Wisconsin's. The results suggest that it is possible to manage northern hardwood stands sustainably with diameter-limit cuts, combined with removal of poorly performing understory trees. Adjusting the diameter limit gave rise to stands similar in productivity and structure to those obtained by BDq cutting regimes. Given their simplicity of implementation and monitoring, more attention should be given to diameter-limit cutting regimes, with attendant stand improvement measures, as a practical means for uneven-aged management of northern hardwoods.

“…Indices quantifying tree size diversity have also been applied as integrated parts of growth simulators to quantify the influence of different treatments on stand structure, and as tools that facilitate the control of silvicultural treatments in forest management analyses (e.g. Buongiorno et al, 1994Buongiorno et al, , 2000Schulte and Buongiorno, 1998;Wikstöm and Eriksson, 2000;Buongiorno, 2001). Some growth models comprise subjectively assessed variables describing stand structure (e.g.…”

“…The economic questions of uneven-aged management have been studied in several studies by employing static models (Adams and Ek 1974), dynamic optimization models (Haight 1985), and simulation-based comparisons of alternative management regimes (Schulte and Buongiorno 1998;Knoke and Plusczyk 2001). However, the effect of fire risk on optimal management or value of uneven-aged stands is largely unexplored.…”

We evaluate the economic efficiency of evenand uneven-aged management systems under risk of wildfire. The management problems are formulated for a mixed-conifer stand and approximations of the optimal solutions are obtained using simulation optimization. The Northern Idaho variant of the Forest Vegetation Simulator and its Fire and Fuels Extension is used to predict stand growth and fire effects. Interest rate and fire risk are found to be critical determinants of the superior stand management system and timber supply. Uneven-aged management is superior with higher interest rates with or without fire risk. Alterations in the interest rate affect optimal stocking levels of uneven-aged stands, but have only minor effects on the long-run timber supply. Higher interest rates reduce rotation length and regeneration investments of even-aged stands, which lead to markedly reduced timber supply. Increasing fire risk increases the relative efficiency of evenaged management because a single age cohort is less susceptible to fire damage over the course of the rotation than multiple cohorts in uneven-aged stands. Higher fire risk reduces optimal diameter limit under uneven-aged management and decreases optimal rotation length and planting density under even-aged management.
