Recent overgrazing is strongly affecting the grassland communities of Inner Mongolia, China. Plant communities previously dominated by Stipa spp. and Aneurolepidium chinense are being replaced with short grasses. Among such grasslands, the Iris dichotoma community occurs in Hulunbeier. Since I. dichotoma is unpalatable to livestock, the community is less utilised. Consequently, some plants, such as Pulsatilla turczaninovii, Saposhnikovia divaricata and Galium verum still grow abundantly under the protective umbrella of I. dichotoma. This appears to be a good example of a plant defence guild (Atsatt and O'Dowd 1976). Controlled grazing, in order to prevent damage to such communities, has been recommended from the point of view of plant ecology.
