SOME RECOMMENDATIONS ON RESEARCH OF VEGETATION COVER AT PERFORMANCE OF ENGINEERING- ECOLOGICAL SURVEYS

Abstract

The article presents the method of organization and research of flora at environmental surveys in accordance with general requirements and rules (SP 11-102-97, SP 47.13330.2012). The aim of the work is to form the basic approaches for qualitative research of flora objects in the performance of engineering and environmental surveys based on the analysis of existing normative legal acts in the field of nature protection, using scientific methods. The suggested methodological recommendations and proposals for solving some of the problems associated with the study of vegetation cover based on the personal experience of the authors. As a result, the whole complex of works consists of three steps: step 1 includes work with literary and stock data on the study territory; work with herbarium collections. Selection of topographic maps and remote sensing data, development the plan of actions and expedition route. The implementation period is January — May. In the step 2 — expedition work. Perform geobotanical descriptions. Determine the coordinates of rare and protected species and assess the condition of their cenopopulation. Decode the remote sensing analysis and develop a preliminary legend of the geobotanical map. The implementation period is May-September. Step 3 — desk work. Prepare a report containing the characteristics of the area, methods and results of research: a description of vegetation, an annotated list of plant objects, indicate the coordinates of the location of protected plant objects and develop recommendations for their protection. A large-scale vegetation map (scale 1:10 000 and larger) is compiled, in which the selected natural-territorial complexes of the investigated territory are displayed in detail. The implementation period is September-November. It is note that, due to the laboriousness of individual stages of work, there is a need to attract experienced and qualified specialists. It is specific that the period of expedition work and natural and climatic features of the study area should be take into account in the research work on the study of vegetation in environmental surveys.
