Abstract:
This study examined the current survey of the vascular plants of dicotyledon wild during the study period (2013 - 2012) In the area of Sudoor - Diyala, the study was based on the 774 samples of plants with their duplicates as collected by The Researcher. All of these collections have been cacched in the Iraqi herbariums. To be specific there are 186 species which relate to 133 genus and 43 families. All these, have been scientifically classified with thier local and common Iraqi or arabic names.Besides, their duration and economic importance (medical, toxic, nutritional or forage, artificial, harmful, aromatic, ornamental, fuel plants or other uses). Moreover, their geographical distribution in the districts of Iraq and thier geographical existence in neighboring countries to Iraq (Saudi Arabia, Kuwait, Turkey, Iran, Syria and Jordan) , and the study results statistics have shown that the vast majority of the collected species are Herbal Plants totalling 164 species out of 179 species in all.This, in fact, can be ascribed to the impossibility of txonomizing 7 plants species for the incapacity to obtain their flowers or fruits. As for the shrub species it amounts to 13 species where as the number of woody species of trees is 2 only. As for the economic plants and their significance, let s mention the fact that the number of plants used as forage amounts to 86 species, the medical plants are 83 species, the toxic plants fall into 43 species, the ornamental plants are 23 species, the industrial plants are 14 species, the weed plants are 11 species, the aromatic plants are of 6 species, and the plants used as fuel are of 4 species. It also appears that the majority of the plant in the area of study is widespread in the various districts of Iraq, i.e. the number of such plants amounts to 110 species, however, there are plants of medium spread in the districts of Iraq, i.e. the number of such plants amountsto 54 species.There still are some plants whose geographic distribution has no been identified in the districts of Iraq and their number is 15 species, and as for their geographic extension into the neighboring Countries, these plants amount to 116 species in Saudi Arabia, 84 species in Turkey, 81 species in Iran, 79 species in Kuwait, 69 species in Syria and 26 species in Jordan. Furthermore, the species of plants collected perviously and have not been found during the period of study amount to 32 species and these relate to 13 families.The shrinkage of the vegetation cover in the area of Sudoor is attributed mainly to the drought conditions and the wind soil erosion which the area has undergone in the previous years. Besides, there are some other reasons including the overgrazing, the expansion of agriculture and the unstudied projects of construction, which have resulted in the disappearance of natural plants in the area.
