Tree growth and mortality are two central processes in mixed structurally complex moist tropical forests, yet accurate estimates of the variables needed to model them remain sparse scattered. It is thus still difficult predict forest evolution at a local scale build reliable management plans. To help fill this gap, for 1–7 years we annually monitored 21,180 trees belonging 42 species exploited ...

Knowledge of tree age-size relationships is essential towards evaluating the sustainability of harvest regulations that include minimum diameter cutting limits and fixed-length cutting cycles. Although many tropical trees form annual growth rings and can be aged from discs or cores, destructive sampling is not always an option for valuable or threatened species. We used an individual-based popu...

Complexity in ecological systems has challenged forest simulation modelers for years, resulting in a number of approaches with varying degrees of success. Arguments in favor of hierarchical modeling are made, especially for considering a complex environmental issue like widespread eastern hemlock regeneration failure. We present the philosophy and basic framework for the NORTHern Woodland Dynam...

Large-scale manipulations of dead wood in mature Pinus taeda L. stands in the southeastern United States included a major one-time input of logs (fivefold increase in log volume) created by felling trees onsite, annual removals of all dead wood above P10 cm in diameter and P60 cm in length, and a reference in which no manipulations took place. We returned over a decade later to determine how th...

We determined the size of differences in stand and tree growth semi-natural forests with respect to 16 reference soil groups. The forest area Slovenia (11.8 thousand km2) was used as study area, units were derived from national map at a 1:25,000 scale consisting 10,781 polygons an average 117.95 ha. Stand defined periodic basal increment, while Norway spruce, silver fir, Scots pine, European be...

Accurate methods of reconstructing historical tree diameters from increment cores are important because diameter is used in allometric equations to predict stand characteristics and to study stand dynamics. The conventional reconstruction method assumes that the pith is in the centre of the stem. This is often incorrect, as evidenced by a pith increment index quantifying the deviation between t...
