Trendi v gozdnem semenarstvu in drevesničarstvu v Sloveniji
Ob pričakovani večji pogostnosti in obsegu ujm sta nas žled februarja 2014 in namnožitev lubadarjev 2015 in 2016 opomnila na problematičnost preskrbe s semenom in sadikami. Pregledali smo obseg obnove s setvijo in sajenjem v zadnjih dvajsetih letih ter načrtovano porabo sadik in zaloge sadik v slovenskih drevesnicah. V Sloveniji se obseg obnove gozdov s sajenjem in setvijo zmanjšuje kljub vse večjim potrebam po obnovi gozdov po sanitarnih sečnjah; gozdno drevesničarstvo in semenarstvo razvojno zastaja. Trenutno v Sloveniji nismo sposobni zagotoviti zadostnih količin semena in sadik vseh ciljnih drevesnih vrst za potrebe sanacij v slovenskih gozdovih.
In the light of the anticipated higher frequency and the extent of natural disturbances, the catastrophic sleet in February 2014 followed by bark beetle gradations in 2015 and 2016 reminded us of the impaired supply chain with seed and seedlings in Slovenia. In this paper, we analysed the trends of artificial regeneration in the last 20 years and gaps between the planned use and the current stock of seedlings in Slovenian nurseries. The extent of forest regeneration with seeding and planting is decreasing in Slovenia; forest nurseries and seed production are stagnating. Currently, we are not able to produce the required number of seedlings of desired target species to reforest areas damaged by past and ongoing natural disturbances.
