Two studies were carried out to evaluate the rangelands subjected to grazing pressures (GP) at differentlevels with single (SSG, cattle) - or multi (MSG, cattle, sheep and goats)-grazing animals species(GAS) for a long time in Zonguldak province, Turkey. These studies were done in 2015 and 2016 years.The GP treatment was classified as <0.30 (very low, VL), 0.31 to 0.60 (low, L), 0.61 to 0.90 (high, H)and 0.91< (very high, VH) livestock unit (LU) ha-1. The percentages of decreaser, increaser and invaderrange plant species, including shrub and herbaceous species and rangeland condition score interactedamong the GP and GAS treatments. The percentages of decreaser species in the MSG communitiesunder the L level and in the SSG communities under the VH level were higher compared to othertreatments. The rate of shrub species in the VL rangeland subjected to SSG was higher than that in theVH rangeland. The rate of shrub species in VH range subjected to MSG was higher than that in otherranges subjected to MSG and in VH range subjected to SSG. The frequencies of decreaser and invaderspecies of SSG were higher than that of MSG, but the frequency of increaser species was lower thanthat of MSG. The range condition class for the SSG and MSG rangelands were “poor” and “fair”,respectively. These results indicate that increasing GP prevents animals from grazing selectively and theMSG system can contribute to the control of weeds.
