Representative regions of cedar plantations were revealed in different height-belt complexes of the Borus ridge (the northern part of the Zapadny Sayan Ridge). Test grounds were settled with sampling the model trees according to the differentiated procedure checked in the Sayan-Shusha reserve. A retrospective analysis of seminiferous characteristics and the growth of female shoots of Siberian cedar was carried out. The dynamics of seminiferity was determined for the cedar forests growing under different ecological conditions. A less expressed amplitude of productivity over years is characteristic of the under-cliff taiga cedar growth. A possible dependence of the next-year productivity on the growth of the shoots of female generative stage was analyzed: a substantial development of the female generative stage is observed during the year preceding a good crop.
