The Karadag reservation can serve as a base for stationary resource study of the SouthEastern Crimea medicinal plants. The reservation flora is rich in medicinal species, but only few of them could be of potentially producers' value. Rosa canina L.S.l. is the most widespread medicinal plant in the reservation and adjacent regions. Discussed here are the ecological peculiarities of Rosa canina L.S.l., quantity and productivity of dogthorn in the associations of its phytocenocomplex, age structure and morphometric features of cenopopulations, vitality, age dynamics of production and diseases. The obtained data could be extrapolated on the adjacent areas. <P>
