One of the causes of decrease of species diversity of forest ecosystems could be inadequate selection of tree species for afforestation and ameliorations. It is known that by establishing new forest ecosystem habitat conditions change, and thus, edaphic and hydrological conditions and light regime also change, which directly or indirectly reflects on plant species. The research included four artificially established stands (pure or mixed) in the area of Kosmaj, where various coniferous species were introduced in the process of substitution of autochthonous forests of Hungarian oak and Turkey oak. The largest total number of plant species was recorded in artificially established stand of common spruce, Atlas cedar, and Douglas-fir (41). The highest Shannon-Wiener diversity index was recorded in stand of Douglas-fir (3.22), and the lowest in pine stands (2.95-2.97). It was determined by cluster analysis that stand of Austrian pine and stand of Austrian pine and Scots pine have the largest degree of mutual floristic similarity.
