摘要: The circumference of trees in the CONECOFOR permanent monitoring plots (PMPs) were measured by three surveys carried out 1997, 2000 and 2005. Plots arranged into forest types according to tree species, management system stand structure: beech ( Fagus sylvatica L.) spruce Picea abies K.) high forests, aged coppice forests transitory crops (deciduous, evergreen oaks beech). Diameter distribution, basal area, area increment, mortality rate in-growth calculated per layer (dominant, intermediate, dominated) within each PMP, point relative contributions changes. A range annual growth was detected both between over monitored period, but an obvious reduction increment found two/thirds 2000-04 as compared 1997-99. Current mortality, mostly allocated dominated intermediate layers, can be explained “regular” due overstocking inter-tree competition almost all observed case-studies. Opposite patterns occur for vs. other owing different dynamics progress. Drought 2003 is likely large-scale factor determining reduced course second period.
