The article deals with the results of researching the diversity of biotypes andtheir floristic composition in the territory of existing and abandoned quarries in Volyn Polissya (Kostopil and Volodymyrets regions, Rivne oblast). Studies have revealed 562 species of higher vascular plants of 347 genera and 92 families. A great variety flora´s species is connected with the diversity of ecotopes that have formed there as a result of anthropogenic and natural factors. Characteristic features of this territory are various micro and mesorelief forms, which differ ecological conditions and determine the ecotopological differentiation of the species composition quarry´s flora and the territory in general. Soil substrate or chemical composition of water have the greatest influence on the plant´s composition of different ecotypes, the sunlight has less influence. The largest species diversity of flora characterized by ecotopes in meadow and tree-shrub vegetation, they are transformed variants of natural groups, as well as overburden dumps and landfills, where the main plant community are synanthropic species, in particular adventitious plats. In some areas, where basalt mining has been stopped for more than 15–20 years there are processes of renaturalization, we can see there spreading of rare plant species.
