Heavy collecting induces smaller and deeper Fritillariae Cirrhosae Bulbus in the wild

Fritillariae Cirrhosae Bulbus is a well-known traditional Chine medicinal herb. However, the demand for this herb is leading to over-collection and its decline in the wild. This study aims to investigate the ecological conditions of Fritillaria cirrhosa under the influence of human disturbance, biot...

However, the demand for this herb is leading to over-collection and its decline in the wild. This study aims to investigate the ecological conditions of Fritillaria cirrhosa under the influence of human disturbance, biotic species interactions and climatic conditions. We established a total of 78 plots at 14 sites of F. cirrhosa in its distribution center, the Hengduan Mountains area. At each site, we estimated the abundance of F. cirrhosa at different distances from roads. The diameter and height of F. cirrhosa fruit and bulbs were measured and compared to underground bulb depth. We then analyzed the effects of environmental conditions and human disturbance on the abundance of F. cirrhosa using variance partitioning. We found that (1) abundance of F. cirrhosa and their underground bulb depth showed a significant linear increase with the distance from the main road; (2) the diameter/height of fruits and the diameter/height of fruits/bulbs showed significantly different responses to the human disturbance; (3) the community associates, climate and spatial conditions can explain 58%, 22% and 27%, respectively, of the variance in the F. cirrhosa abundance. These results highlight the fact that human disturbance and biotic factors have a great influence on the survival of F. cirrhosa, even more than climate conditions.http://www.sciencedirect.com/science/article/pii/S2468265917300276Fritillaria cirrhosaHuman disturbancePlant abundanceBiotic interactions
