Abstract


Oak plantation is the repository of unique floral and faunal complexes that maintain the ecological balance in the surrounding disturbed by human activities forest areas. In many cases, their current state is unsatisfactory. Therefore, the cultivation of oak plantations with other species in Southern Podillya will enable developing recommendations in order to promote the formation of oak forest environment. Our research aims at the analysis of state forest fund is carried out in SOE "Chechelnitsky Forestry". In course of the study the authors have examined planting of the forest, melliferous, fruit, and baccate tree species. We have studied forest cultures of common oak composition including black walnut, bird cherry, small-leaved lime, sycamore maple (sycamore), ash, bereka medicinal, Norway spruce, and Norway maples. We have also examined the growth of oak plantations with accompanying tree species. Melliferous, fruit, and baccate planting constitute 51.8 %, namely: involving bereka medicinal – 11.7 %, bird cherry – 49.7 %, and linden-tree – 38.6 %. Moreover, the height of oak planting is studied with concomitant arboreal breeds. The area of fruit, baccate and melliferous cultures is set in an test forest district, percent organic I will fall off, closing of crowns in rows, distribution of grass vegetation. Our research has proved that bereka medicinal and common oak form the first tier under the age of 12-15 years old. Since 30-years-old age height and development of common oak passes more intensively as compared to concomitant arboreal breeds. From 35-years-old and to 96-years-old age this difference concerning common oak makes up to 10 m. Oak clearly occupies the first tier and arrives at a to 25 m height, while bereka medicinal does not exceed 16 m height. Most distribution on frames grass plants have such species as couch-grass creeping, willow-herb, nettle is diclinous et al, that to a 6-year- age form thickets and arrive at a height to 1. 4 m. Thus we have arrive to theconclusion that the arboreal concomitant species are able to promote the ground fertility and planting productivity. Small-leaved lime, bird cherry and bereka medicinal are proved to be promising for introduction in forest plantations in Southern Podillya.
