Diplomska naloga obravnava primerjavo naravne obnove in setve pri sanaciji vetroloma v GGE Železniki. Na tri različna območja so postavili 203 popisovalne ploskve: 1) območje naravne obnove, 2) območje setve (gorski javor in smreka) in 3) območje obnove pod zastorom. Na ploskvah velikosti 2,25 m% so popisali splošne ekološke in sestojne razmere ter ocenili vitalnost dominantnih drevesc. Rezultati so pokazali, da je obnova najbolje uspela na objektu s setvijo (3.951 dreves/ha) in na območju pod zastorom (13.140 dreves/ha). Najmanj osebkov je bilo na objektu z naravno obnovo (593 dreves/ha). Zelo vitalnih je bilo 63 % vseh dreves, vitalnih je bilo 31 % dreves, 5 % dreves pa je bilo slabo vitalnih. Med drevesnimi vrstami sta prevladovala gorski javor in smreka, pojavljali sta se tudi bukev in jerebika. Dejavniki v negativni povezavi z gostoto mladja so bili zastiranje zelišč, maline in bezga. Drevesca so bolje uspevala na dvignjenih terenih, kjer je bilo manj konkurentov. Potrdili so trditev, da mladje bolje uspeva na sestojnem robu. Za boljši uspeh setve in naravne nasemenitve je priporočljiva večletna obžetev pritalne vegetacije.

Sekundarni naslov:	Comparison of direct seeding and natural regeneration for forest restoration after wind- throw in the area of GGE Železniki
Sekundarni povzetek:	The thesis deals with comparison of direct seeding and natural regeneration in strands totally damaged by windstorm in management unit Železniki. On three different areas 203 survey plots were set: 1) area with natural regeneration within open gap, 2) area with direct seeding of sycamore maple and Norway spruce, and 3) area of natural regeneration close to the forest edge. On plots 2.25 m% in size overall ecological and strand conditions, seedling density as well as characteristics of dominant trees were analysed. The results showed that the highest seeding densities were achieved with direct seeding (3.951 trees/ha) and within the area of forest edge (13.140 trees/ha), while lowest density was within area of natural regeneration (593 trees/ha). As very vital 63% of trees were assessed, as vital 31% of trees, 5% of trees showed poor vitality. Most abundant seedlings in all treatments were sycamore maple and Norway spruce, followed by beech and ash. Coverage of ground vegetation, raspberry and elderberry was negatively associated with the seedling density. The later was also higher on elevated terrain with fewer competitors. The study confirmed better regeneration potential of forest at strand edges. For a better success of direct seeding and natural regeneration a multi-year control of competing ground vegetation is recommended.
