distribution patterns of introduced plants to iran

during the past decades, several plant species have been introduced to iran wich there is no compiled data about them. due to the lack of an ecological-geographical database on introduced plant species to iran, a study to compile and analyze their information for management planning seems necessary. in this study, a databace related to mentioned plant taxa introduced to iran was prepared using data from field studies and review of available resources. dissemination maps using arc-gis ver. 10.3 was drawn. also using 0.25° × 0.25° grid cells in diva-gis software environment ver. 7.3 species richness maps was drawn. the results of this study showing that 28 introduced species of the index are found in iran and the hyrcanian geographical province has a higher richness. therefore, this study, while introducing the management priorities of the introduced species, has introduced general strategies for their ecological management so that it can be used as a basic scientific resource for biodiversity management programs in iran.
