We compared steppe vegetation inside and outside Hustai National Park near the capital ofMongolia to evaluate the effects ofnational park protection. Grazing has been prohibited in the park since l 993 but allowed to con − tinue in the buffbr zone adjacent to the park boundary. Using phytosociological methods , we conducted vege − tatbn surveys in eight stands in the park and 25 stands in the buffer zone . In particular , we compared vegeta − tion cover , surface sward height , and species

The results demonstrate that vegetation cover , surface sward height , and species richness were sig − nificant 】 y higher in the park than in the buffer zone . Moreover, NMDS results demonstrate that the stands ex − hibited different spatial patterns in each area , suggesting that protective measures a 【 so a 幵bcted species composi − tion. These differences between the areas appear to have occurred owing to a combination ofvegetation recovery in the park and degradation in the buf 発 r zone .
