For large scale forest and land use studies simple but general models are necessary due to the limited resolution of available data. Based on theory for stand dynamics and competition, models of stand density and thinning effects are developed for scenario simulation and for large scale density mapping.
Some key results :
- A general stand density model for growth and mortality effects of thinning predicts that the optimal thinning intensity is similar among different species
- Stand density can be estimated from productivity and biomass data, e.g. based on large scale inventory and remote sensing data sets.
