The issue of the conservation status of Euphorbia glareosa Pall. ex Bieb. (Euphorbiaceae Juss.) on the territory of the Republic of Bashkortostan is considered in the article. In the second edition of the Red Data Book of the Republic of Bashkortostan [2011] this species was included in the regional list of rare species that need biomonitoring – «List of objects of flora and fungi that are not included in the Red Data Book of the Republic of Bashkortostan, but need special attention on the territory of the republic to their state in the natural environment and monitoring». The article provides the following information about the species: morphological description with an indication of the main diagnostic features; modern data on the distribution of the species in the republic; brief ecological and phytocenotic characteristics; features of biology (according to data from literature sources); modern data on the number and state of local population; limiting factors; adopted and recommended protection measures, data on the possibility of preserving the species in culture. On the territory of the Republic of Bashkortostan, the species E. glareosa достоверно is known only from one point – the southern shore of Lake Aslikul in the Davlekanovsky district (the territory of the Asly-Kul natural park). In the republic, E. glareosa is a poorly studied species and is located at the edge of the range (at the eastern and northern limits of distribution). The known population is small 50-80 generative individuals). The population is subject to negative anthropogenic and natural influences. The species is poorly resistant to these influences. The species is on the verge of extinction. The data presented in the article fully justify the possibility of excluding the species Euphorbia glareosa Pall. ex Bieb. from the regional list of rare species «List of objects of flora and fungi that are not included in the Red Data Book of the Republic of Bashkortostan, but need special attention on the territory of the republic to their state in the natural environment and monitoring» and including it in «List of objects of flora and fungi listed in the Red Data Book of the Republic of Bashkortostan» (third edition, 2021) (category and status: 1 – endangered species).
