Geographical interpretation of local data allows detecting types of spatial organization for species ranges, environmental factors of species population distribution and biotic cover as a whole. The theoretical concepts for coenotic range, range optimum, geographical and genetic elements of flora and fauna have an important role for development of this study as well as cartographical method and GIS-technology in areology. It is supposed to assess the plant species activity by their abundance and constancy within different classification units and by their belonging to certain diagnostic species group. Quantitative records of some animals are implemented by standard methods within the whole range territory. Our researches include the ranges’ classification according to the northern boundary position and mapping range structure for typical species of boreal biota.
