The Research took place in managed silver fir-beech forests in GGO Novo mesto and GGO Kočevje. Eight gaps were included in the research. The purpose was to investigate the regeneration and basic ecological factors for each gap and compare them with the first inventory. Five gaps were made with regular cutting (new gaps) and the remaining three were being made by irregular shelterwood based on tending and were selected (old gaps). In each gap a 5x5 mgrid was installed. Corners represented the locations of plots 2,25 square meters in size. On each plot in eight gaps the following parameters were assessed: ground coverage, woody regeneration, browsing impact, growth of 5 dominant beech seedlings and light conditions. Light conditions were more thanthree times smaller in old gaps. In the period 2005 / 06, the share of coverage by ground vegetation was more than 50 % in new gaps. The density of one year old seedlings was smaller in old and higher in new gaps in 2005 / 06.The regeneration of silver fir increased by 2005 / 06. Length, diameter andheight increment were higher in old gaps. Browsing impact and growth morphology of beech were improved in year 2005 / 06. The total lack of silver fir and sycamore appears in higher height classes. Higher beech samplings are found in the northern part of gaps, whereas the overall quality of the regeneration was better in old gaps.
