Abstract

Complex studies of rare plant species allow to evaluate the status of their populations and develop an approach to their conservation. During the last years, detailed studies of rare legume species have been performed on the territory of Buryatia. They revealed new species localities, and characteristic features of species distribution and population structures. The goal of the current research is to summarize all available information including the latest data in order to develop practical recommendations for rare legume species conservation in the examined region. Populations of rare legumes and plant communities containing them were studied by traditional methods. Species distribution was analyzed using the locality database for rare vascular plants in Buryatia which contains critical information from the last edition of Red Data Book for the examined area. Distribution, eco-coenotic confinement and population structure of rare legume species in Buryatia were studied. The structure of key species populations was estimated with respect to their phytocoenotic and geographic confinement. Rare legumes populations are mostly insufficient (excluding juvenile and senile individuals), definitive, normal, and mature. Unimodal age spectra with prevalence of generative plants typical of populations from undisturbed habitats. Human impact or other exogenous factors led to formation of bimodal age spectra. The strategy for conservation of the examined species should be based on protection of their habitats and sustainable use of plant communities containing rare legumes. Further research into biological and ecological features of rare legumes, strict protection of isolated habitats, regular monitoring of populations sizes are required
