Abstract

Separation of invasive plant species from other plants is essentially needed in studies related to plant diversity to avoid any misleading judgments about rangeland ecosystem plant diversity. This study aimed to investigate the effect of Livestock grazing intensity on diversity, richness and evenness of invasive plants in Semi-steppe rangelands of Kabirkoh, Darrehshahr, western Iran. Three areas subjected to long-term heavy, moderate and lenient grazing intensities along with an exclosure were considered as grazing treatments. Vegetation was sampled with randomized-systematic method using transect line in 100m length and 1m2 quadrat. Then variance, richness and uniformity indicators were performed with Past and Ecological Methodology software. Data of invasive species were separated from other data prior to calculation of species diversity, richness and evenness indices with Shanon-wiener and Simpson`s diversity indices, and Peet and Sheldon indices, respectively. Data were analyzed by one-way ANOVA and Lowest Significance Difference (LSD). The amount of diversity indices in grazing intensities treatments varied significantly (P<0. 05). The highest values of Simpson and Shannon index were in heavily (0. 974) and lenient (4. 69) grazed rangelands, respectively, whereas the lowest values of the indices were 964. 0 and 4. 0501 in grazing exclosure rangeland, respectively. The amount of species richness indices in rangeland under heavy grazing of livestock was higher than other grazing treatments. The Menhinick richness index showed that the richness of invasive species in the region under heavy grazing intensity was 25. 5 and 15. 73 percent higher than that in lenient and moderate grazing intensities (P < 0. 05). There was no significant difference in species evenness index in grazed areas with different intensities including heavy, moderate, lenient and exclosure (P < 0. 05). The highest values of Peet and Sheldon indices were in rangeland under lenient grazing.
