The article describes the results of the research on transplantation of Rhododendron aureum. This species is listed in the red book of the Transbaikal territory, it is wide-spread at the construction site of Udokan Mining and Processing Complex. Since 2018, Baikal Mining company has been constructing the largest complex for mining and production of copper ore in Russia. Rhododendron aureum an evergreen shrub – was found at the construction site. As the result of the mining and processing complex construction and operation, some communities including Rhododendron aureum Georgi will be disturbed. This species is difficult to introduce into the culture, grows slowly. It starts blooming and fruiting only on 12th year. As compensatory measures for the protection of the species, researchers proposed transplanting this species. As a result of research, the possibilities and limitations of carrying out activities for transplanting and rehabilitation of this species were established, sites for extraction and planting were proposed, and a technology for preparing sites was developed. Sites for mining and transplanting were chosen as similar as possible in terms of conditions: the nature of the terrain, exposure and steepness of the slopes, and moisture conditions were taken into account. In August 2019, 320 specimens of the Rhododendron aureum were transplanted to a specially prepared site. The first results showed good acclimation at compliance with the requirements for transplantation and preparation of the area. This experience can be used for rehabilitation works mountain subalpine ecosystem.
