An integrated assessment of wild vegetable resources in Inner Mongolian Autonomous Region, China

This paper was based on ethnobotanical investigations conducted from 2004-2006 in Inner Mongolian Autonomous Region of northern China. Today, due to their nutritious and relatively pollution-free characteristics, wild vegetables are playing an increasingly important role in peoples' health and well-being. This paper aims to provide scientific clues for the selection of special and high quality wild vegetables species.

An ethnobotanical study, consisting of a literature survey, open-ended and semi-structured interviews, and collection and identification of voucher specimens was carried out to gather information on wild vegetables in Inner Mongolia. Next, an integrated assessment of 90 species of wild vegetables was performed using the linearity weighted integrative mathematical analysis method.

According to an integrated assessment of 90 species of wild vegetables in Inner Mongolia, there are 5 species with the highest integrated value, 40 species of high-integrated value, 43 species of general integrated value, and 2 species of low value. The results indicate that the vast majority of wild vegetables have high value in Inner Mongolia.

Inner Mongolia is rich in wild vegetable resources. A comprehensive assessment indicates that the vast majority of wild vegetables are of high value. However, these wild vegetables are seldom collected or cultivated by local people. Most of the collected species require further research and investigation into their nutrient content, toxicity and ethnobotany to illuminate their potential as new cultivars or products.
