The aim of the study was to evaluate long-term state and development of forest regeneration in the area of forest management Deblín (Lesy města Brna, a.s.). Spruce (41,09 %) is the most represented evergreen tree (conifer). Forest management file 45 is that the most represented. 10 years' time period was selected for survey of the state of regeneration (forest management plan 2002 -- 2011). On the basis of the available forest management plan and forest management records the ratio of natural and artificial regeneration in every year was stated - for individual forest management files and whole forest management. Part of the work was also a field survey to assess the forest establishment. On forest management Deblín there were regenerated approximately 222 hectare (7 %) during the years 2002 -- 2011, from that amount 74% was artificial regeneration and 26 % was a share of natural regeneration. Restoring forest area on forest management file 451 is 23 % from which 91 % is artificial regeneration. Natural reproduction wasn't shown on forest management file 017 and forest management file 253. Natural reproduction (59 %) predominates on forest management file 456. On the average 6500 pieces/hectare were planted. Spruce represented only about 29 % and scotch pine about 9 % in artificial regeneration during the years 2002 -- 2011. On the other hand, the planting of oak (about 25 %) and larch (about 14 %) raised. Average costs for regeneration of 1 hectare of forest were 56 306 CZK in the year 2005, 40 347 CZK in the year 2006 and 45 909 CZK per hectare in the year 2007. From the all 20 analysed young forests four weren't evaluated as established after 7 years' time from planting. The limiting factor was the game or unsuitable species composition.
