Abstract: 

INVASIVE WEED IS A NATIVE OR NON-NATIVE SPECIES WITH INTRODUCING TO A NEW REGION EXPAND ITS TERRITORY, THREATENING THE BIODIVERSITY AND CAUSED UNDESIRABLE ECONOMIC AND ENVIRONMENTAL CONSEQUENCES. FEATURES OF THE NEW AREA, IS THE MOST IMPORTANT FACTOR DETERMINING THE SUCCESS OF THIS SPECIES INVASION HOSTING. INTERACTIONS BETWEEN SPECIES AND FEATURES OF NEW ENVIRONMENT, DETERMINES THE SUCCESS OF THE INVASION. METHODS OF PRODUCING CROPS PROVIDE INVASION OPPORTUNITY FOR INVASIVE WEEDS AND SEEMS THE INVASION INTEGRATE WITH MONOCULTURE IN NEW MODERN AGRICULTURE. INVASION PROCESS DIVIDED IN THREE STAGES; INTRODUCTION, COLONIZATION AND NATURALIZATION AND IF THE INVASION COULD BE DETECTED IN THE EARLY STAGES, CONTROL WITH MINIMAL EXPENSE AND TIME SPENT WILL BE DONE. FOR PRESENCE OF INVASIVE WEEDS IN IRAN HAVE A LOT OF DATA, MAINLY DUE TO THE SUBJECT ARE: 1- LOW IMPORTANCE BEING INVASIVE WEED PROBLEM 2- LACK OF A PERMANENT AND ACTIVE MONITORING SYSTEM. BUT THE INVASION OF AZOLLA (AZOLLA PINNATA) IN RICE FIELDS IN NORTH REGION OF THE IRAN, DISTRIBUTION OF WILD BARLEY (HORDEUM SPONTANEUM) IN WHEAT FIELDS AND PRESENCE OF (CYNACHUM ACUATUM) IN ORCHARDS OF DIFFERENT REGIONS ARE WELL DEFINED. THE FIRST STEP IN INVASIVE WEED MANAGEMENT PROGRAM OPERATION, NOT DIRECT OPERATIONS AGAINST THOSE WHO LEGISLATE IN THIS AREA AND IN OUR COUNTRY IN THIS AREA HAVE SERIOUS CHALLENGES.IF WE WANT SUCH THIS AGREEMENT MUST BE EFFICIENTLY THE COMBINATION OF BASIC AND APPLIED RESEARCHES MUST BE DOWN,, AND FINALLY BE TAKEN TO ENSURE SUCCESSFUL MANAGEMENT OF INVASIVE PLANTS. CURRENTLY, INVASIVE WEED SPECIES PRESENCE BASED ON GEOREFERENCED DATA OF INVASIVE SPECIES AND THEIR GROWTH HABITS IN DIFFERENT AREAS USING GEOGRAPHIC INFORMATION SYSTEM (GIS) CAN BE PREDICTED.
