Abstract

Negative and positive INTERACTIONs among plants have important role for species coexistence and community diversity. The strength and direction of the INTERACTION effect may change with environmental disturbances such as GRAZING and FIRE. This study was aimed to evaluate the effects of environmental disturbances such as FIRE and GRAZING on INTERACTIONs between SHRUBs and herbs in rangelands of Goghar Bafte. Hence, beneath 20 dominant species of Artemisia aucheri and 20 open patches, a quadrate of 20 cm×20 cm was plotted and the variation in the biomass, richness and vegetation cover of herbs were measured in regions under exclosure, FIRE and GRAZING. Results showed that biomass and vegetation cover of herbs were increased by SHRUB presence because of positive INTERACTION between SHRUBs and herbs inside exclosure.Although the facility of SHRUBs was reduced by GRAZING and FIRE, its rate was not equal in both places. Under GRAZING, INTERACTION between SHRUBs and herbs remained positive but SHRUBs were severely damaged by FIRE and the INTERACTION between species altered from positive to negative.The overall conclusion is that FIRE plays a more important role in changing the INTERACTION between SHRUBs and herbs.
