DISTRIBUTION AND RESERVES OF RARE AND USEFUL / Монголын эм зүй, эм судлал

ABSTRACT

Rare and endangered 5 species are distributed to grow in Tuv aimag. Global warming, aridity, livestock grazing, and mining factors effect to lose the distribution area of those rare and endan- gered species. Therefore, it is important to study for their accurate population size. Based on that protection works could be evenly distributed within the areal distribution. It is rather demanding work to make test study for finding new sites that needed to protect, to restore those rare and endangered species and to make plantation, to domesticate for transplantation and multiplication and to protect gene pool by the method of biotechnology. Key words Tuv aimag, useful plants, distribution, reserves
