In this paper the evaluation of nine restocking plantings of common yew (Taxus baccata L.) is presented. Localities represent different site conditions typical for the Protected Landscape Area Lužické hory Mts., Czech Republic based on edaphic categories and forest vegetation zones. The for was to evaluate selected yew characteristics 4 years after planting, to compare localities, determine the effect of habitat conditions, as well as seedling protection methods. Observed for all individuals at all sites were height, stem base diameter, growth shape, defoliation, coloration of needles, and presence of pests. Height and stem base diameter were compared using multiple comparison methods. As for height and basal thickness of seedlings, the best results were achieved in conditions of the 4th forest vegetation zone (beech) on compacted acid, nutrient-medium and partly acidic soils, on small clearings with side shading and in individual wire fences. The worst results occurred in the 6th (spruce with beech) and partly also in the 5th (beech with fir) forest vegetation zones on stony-colluvial and partly acidic edaphic categories, in conditions of a relatively closed beech canopy and in individual wooden fences.
