ABSTRACT Mainly aim's this bachelor's thesis was establishing and making primaeval evaluation of birch's sucessfull regeneration on calamity clear cut area. Two TVP were establisching on calamity clear cut area this towards. Calamity clear cut areas were name big on acreage 900 square meters and small on acreage 625 square meters. Birch was regenerating of sawing in two term's, first was autumn's and second was spring's. Sawing's ratio was 1g on 1 square meter for both terms. Evaluation qualities of seed was of part work's. TVP were spliting on element on acreage 25 square meters.for watch of regeneration. Little areas were demarcation in the middle element of TVP. On this little area waged evaluation of occurence woodly species, evaluation of coverage's vegetations and evaluation qualities soil's substrate. Little areas were establisching on calamity clear cut area for watch on influence soil preparation and term of sawing on sucessfull regeneration currently. Evaluation passed of in two terms, first were autumn's and second were springs. Highs overgroud part's birch and also root collar thicknes of highest seedlings were mesuring at the everyone element's on end vegetation season's. Average abundance of birchs were 14,44 ks at the little areas of big area and too average abundance birchs were 0,37 ks at the little areas of big area first year's spring. Average coverage's of vegetation were 47,4% at the small area on summer and next average coverage's of vegetation were 24,22% at the big area on summer. Autumn's and spring's sawing without soil preparation was succesfullest from all number of variants. Average talllnes of thirty six samplers was 38,17 cm and average root collar thickness of thirty six samplers was 5,75 mm.
