Natural regeneration of forest inventory and analysis on the example of the Kurunuka cadastrial unit

Käesoleva töö eesmärk on hinnata Kurunuka kinnistu kümne aasta vanuse raie uuenemist ja vaadata milliste puuliikidega on eraldis uuenenud. Lisaks on eesmärk võrrelda 2001-2012 ja 2013-2022 metsamajandamise kava. Töös on kasutatud iseseisvalt mõõdetud inventeerimise ja ringproovitüki meetodil saadud mõõtmiste andmeid, lisaks metsamajandamise kavade 2001- 2010 ja 2013-2022 andmeid. Mõõtmised toimusid 2012. aasta sügisel ja 2013. aasta kevadel. Prooviala on uuenenud ebaühtlaselt, peamiselt hariliku haava, arukase ja halli lepaga. Haava keskmine kõrgus on 2,5 m, arukasel 2,6 m ning hallil lepal 3,2 m. Pärast mõõdetud andmete arvutamist selgus, et puude keskmine arv hektarile on haaval 9611, arukasel 5841 ja hallil lepal 6203. See näitab küll head uuenemist, kuid uuenemine alal on siiski ebaühtlane. Selleks, et saada ühtlase kasvuga puistu, tuleks proovialal teha hooldus- ja vajadusel ka istutustöid.The goal of current thesis was to estimate ten years old felling regeneration of the Kurunuka cadastrial unit and observe the existing tree species on the regenerated area. Additional purpose was to compare Forest management plans of the years 2001-2010 and 2013-2011. In this study inventory data were gathered by using circular-plot-method, additionally forest management plans of 2001-2010 and 2013-2022 were compared. The measurements were made in autumn 2012 and spring 2013. In the sampled area the regeneration was heterogeneous, the area was covered mainly with Eurasian aspen, silver birch and grey alder. Average height of Eurasian aspen was 2.5 meter, the silver birch and grey alder were in average 2.6 and 3.2 meters, in respective. The average number of trees Eurasian aspen per in hectare was 9611, silver birch and grey alder where in average was 5841 and 6203. These results are indicating on good regeneration, still the regeneration in particular area was heterogeneous. This is showing a good regeneration, still in particular area this regeneration is heterogeneous. For that purpose to get homogeneous growth, should do in the sample area maintenance- and in case of need too planting work
