Roots of a half of the seedlings were dipped into the commercial fungal product Ectovit prior to spring outplanting. Fifty seedlings were planted for each tree species and seedling type in each of 3 treatments Autumn Spring Spring Ectovit and 3 replications 4 500 seedlings in total . Eighty-one per cent of containerized and 75 of bareroot seedlings most - 89 of bareroot spruce least - 59 of bareroot pine seedlings survived after the first growing season. Planting time and Ectovit did not have a marked effect on survival with the exception of the lower survival of containerized beech and spruce in autumn than in spring. The most extensive damage caused by game and mechanical weed control was found out in both broadleaves most of the dry leading shoots occurred in beech. Besides beech higher annual height increment of seedlings was observed in autumn than in spring planting time. Effect of Ectovit on seedling growth was not obvious. Keyword reforestation outplanting time fungal inoculation bareroot seedlings containerized seedlings Southern foothills of the High Tatra Mts. with almost million m3 of fallen wood on the area of 12 600 ha were the most affected territory after windthrow in 2004. After processing of windfalls fire started to spread on windthrow clearings and it changed conditions on the soil surface as well as soil moisture and temperature regimes. Many authors studied destructive consequences of windthrows .
