It is noteworthy that all four plant species have been visibly affected by human activities. Human activities have the capacity to alter the phenotypic traits of species, as well as affect changes in plant distribution areas. Commercial harvesting has driven the evolution of camouflage adaptations in Fritillaria sp. and a reduction in height of Saussure sp., both of which are medicinal alpine plants (Law & Salick, 2005; Niu et al., 2021). Harvesting can also result in inadequate seed production, driving a diminution of the populations from being self-sustaining in the field (Peng et al., 2019). And the distribution range of narrow–ranged species will decrease due to human activities (Xu et al., 2019).
