In this research, the effects of Prosopis juliflora on annual natural vegetation, soil properties and farm land in Sirik area in the east of Minab, Hormozgan province was carried out in 2001 and 2005. Since natural ecosystems and their stability, especially natural vegetation are a national wealth, it is necessary to evaluate effects of this invasive species. In this research, at two different times (2001 and 2005) percent age of annual vegetation cover including grasses and forbs were measured with plots of 0.5 m2 under canopy cover of P. juliflora and open area, in the study area. Soil samples were taken at 0-15 and 15-30 centimeter depths and in laboratory soil properties measured. Then, using Mini-Tab softwar, soil and vegetation parameters, in plots sampled, under and outside the canopy cover of this species, were compared with T tests. Results showed that percent of cover of annual vegetation including grasses, forbs and total of percent cover under canopy and open area in years when rainfall is high, have significant difference between percent cover under canopy and open area. Results also show that, there is significant difference in some soil properties such as pH, Electrical conductivity and organic carbon in depth of 0-15 centimeter. Statistical comparison showed pH is decreased in canopy cover and some soil properties such as organic carbon has increased significantly in canopy cover. Despite of the P. juliflora effects on natural environment, because of the natural regeneration, these species regenerate in agricultural lands and gardens with seeds which are transported by water, domestic animals, and wildlife. P. juliflora makes density thicket and reduce table of groundwater. P. juliflora, also, causes undesirable effects on domestic animals, therefore, farmers and ranchers encounter big problem.
