dcterms:description
Our work aimed at studying the strategy of woody plants regeneration during the regeneration of a spruce stand with the admixture of beech and Douglas-fi r by border cutting (NW-SE aspect) on acidic sites of higher elevations in the Bohemian-Moravian Upland. Spruce is better adapted to bear shade than Douglas-fi r. Nevertheless, in optimal light conditions up to a distance of ca. 35 m (about 16% DIFFSF) from the stand edge, the Douglas-fi r can put the spruce into danger as to height growth. By contrast to beech, the density of spruce is signifi cantly higher within the distance of 45 m (about 15% DIFFSF) from the stand edge but further on the situation would change to the benefi t of beech. The density of Douglas-fi r signifi cantly dominates over beech within a distance of 35 m from the stand edge; from 55 m (less than 15% DIFFS ), the situation changes in favour of beech. Beech can survive in full shade deep in the stand core waiting for its opportunity to come. As compared to spruce and Douglas-fi r, the height growth of beech was at all times signifi cantly greater at a distance of 25 m from the stand edge. Converted to practical conditions, spruce and Douglas-fi r with individually admixed beech seedlings showed good prosperity approximately up to a distance of one stand height from the edge. A mixture of spruce and beech did well at a greater distance but good prosperity at a distance of 2--3 stand heights was shown only by beech. Thus, border regeneration eliminates disadvantages of the climatic extremes of clear-cutting and specifi cs of shelterwood felling during which one -- usually shade-tolerant tree species dominates in the natural regeneration (e.g. beech).
