Abstract

Obnova s saditvijo ima posebno vlogo pri premenah gozdnih monokultur. V delu je obravnavana uspešnost saditve v gozdnogospodarski enoti Spodnje Dravsko polje v obdobju 2017-2020. Znotraj enote smo na devetih odsekih po letih razdelili in naključno izbirali ploskve. Na 21,17 ha smo izbrali 40 ploskev (24 ploskev v centru in 16 ploskev ob robu sajenih območij). Na obravnavanem območju so sadili predvsem hrast in beli gaber, v manjšem obsegu pa tudi lipo, češnjo, gorski in ostrolistni javor ter macesen. Uspeh saditve je bil največji pri belem gabru in macesnu, sledili so ostrolistni javor, lipa, gorski javor, hrast in češnja. Delež živih osebkov vseh let je znašal 79 % in se med leti ni veliko razlikoval, medtem ko je bil delež najboljše vitalnosti višji pri starejših saditvah. Na robnih ploskvah in pri jesenski saditvi smo zabeležili večji delež odlične vitalnosti. Vzrok za poškodbe sadik so bili insekti, bolezni ter gojitvena dela. Gostote naravne nasemenitve med sadikami so se kljub obžetvi gibale v razponu 8.000-40.000 na ha, vendar so v zmesi prevladovali beli gaber, tujerodne in pionirske vrste. Uspeh saditve je odvisen od premišljenega izbora in vzgoje gozdnega reprodukcijskega materiala, pravilne in skrbne izpeljave vseh postopkov od vzgoje do saditve, pravočasne obžetve in ograditve ploskev. Zaradi velike ekonomske naložbe bi bilo smiselno razmišljati o skupinskih saditvah v kombinaciji s pospeševanjem naravne nasemenitve.

Secondary title:	Planting success in forest management unit Spodnje Dravsko Polje in the period 2017-2020
Secondary abstract:	Restoration by planting plays a special role in the transformation of forest monocultures. The diploma work discusses the success of planting in the forest management unit Spodnje Dravsko polje in the period 2017-2020. Within the unit, we divided and randomly selected plots of nine sections over the years. On 21.17 ha, we selected 40 plots (24 plots in the center and 16 plots at the edge of the planted areas). In the considered area, oak and white hornbeam were planted and to a lesser extent also linden, cherry, mountain and sharp-leaved maple and larch. Planting success is the greatest with common hornbeam and larch, followed by Norway maple, lime, sycamore maple, oak and cherry. The proportions or surviving specimens of all years was 79 % and did not differ much between the years, although the best vitality was seen in higher and older plantings. We recorded a higher proportion of excellent vitality at the edges and in autumn plantings. The most damage to the seedlings were caused by insects, diseases and silvicultural treatment. The densities of natural regeneration among the planted seedlings ranged from 8.000 to 40.000 per ha, despite vegetation removal, common hornbeam, non native and pioneer species predominated in the mixture. The success of planting depends of the well-thought-out choices of cultivation of forest reproductive material, correct and careful execution of all procedures from cultivation to planting, timely vegetation removal and fencing of plots. Given the large economic investment, it would make sense to consider group planting in combination with the promotion of natural regeneration.
