Landscape approach in justification of creation of plantings of Quercus robur of various phenological forms in the Bryansk region

This scientific article is devoted to an issue of studying of phenological structure of natural plantings of an English oak in the territory of the Bryansk region. The author considers the important area of work development and justification of recommendations on the basis of the received results for the solution of practical problems on increase in effectiveness of reforestation of oak groves. In researches the important part will be assigned to landscape approach. At the beginning of article the review of references on a research subject is provided. Short results of researches on questions of origin of phenological forms at an oak chereshchaty, to regularities of their distribution are given in various types of landscapes, to features of resistance to wreckers and diseases and abiotic factors of the habitat[1].In the main part of article the author explained materials, techniques of phenological observations [2] and results of researches. Phenological observations on the put constants and the temporary trial areas were made [3]. As a result of application of a comprehensive landscape approach it was succeeded to reveal accurate regularities of confinedness of phenological forms to concrete types of landscapes of the Bryansk region [4]. Three types of plantings with various phenological structure were revealed. Data of results of scientific work are issued in the form of charts, maps and provided in the table.It is in conclusion told about the leading role of landscapes in differentiation of plantings of an English oak on early and late phenoforms around carrying out researches. The attention is focused on application of landscape approach to further studying of this question and accounting of the obtained data when developing and holding actions for creation of steady plantings. For each of phenological forms its silvicultural value is specified.By results of researches the author developed practical recommendations for more effective holding reforestation actions in various ways taking into account ecological features of phenoforms of an English oak, their resistance, confinedness to concrete types of landscapes and operating normative documents. It is important to pay attention to clear separation of parties of collected acorns of early and late forms among themselves when landing nursery. Timely holding actions for care of subbody height for third or fourth after the cabin increases effectiveness of reforestation processes.
