The aim of this diploma thesis was to determine what influence has a different size (cover) of clearing on growing cultures after the third growing season, time of planting and a type of planting material. The reaserch was realized on clearings with dimensions 55 x 70 m, 25 x 70 m, in Podsadba and on a big Kalamitná clearing (4,4 ha). There were used four provenances with or without an adjustment of root system. 10 parameters and signs were measured and recorded on each individual tree. Observed values were statistically evalueted and written comment was added. The results of reaserch confirmed that minor restoration elements are more suitable for culturing Douglas Fir as they provide a favourable microclimate. In these areas are lower losses and plants show a greater increase in aboveground part. In terms of time of planting, the most suitable appeared in the early spring planting dates. The adjustment of root system before planting had a negative effect because treated seedlings had lower gain and the losses were on average higher.
