The study of the vegetative coverage of a region in order to exploit its natural sources is of great importance. Islam Abad Gharb is located in Kermanshah between 45, 24 min to 38, 30 min of the eastern longitude and 33, 36 min to 35, 15 min of the northern latitude. Its extent is about 4654, and it is 1335 m above sea level. This city is dry according to amperage formula. It is a mountain city with an average annual rain of 414/72 m. The highest average temperature is 37°C in August, and the lowest average temperature is -20°C in December. The vegetative coverage of the region was determined based on the floristic method, and the biological shape of each plant was determined generally. There are 79 families, 225 genera, and 335 species. Six big families are: Brassicaceae (28 spp.), Gramineae (27 spp.), Papilionaceae (26 spp.), Apiaceae (24 spp.). Compositeae (29 spp.), and Labitate (17 spp.). Therophytes are the most common and compromise 47% of all plants. Others are Hemicryptophytes (24%), Phanerophytes (12%), and Geophytes (10%), that is, 54% of Iranian-Toranian plant.

Among the countries located in western south Asia, Iran has the most diversity of plants, and it is because of its large extent, climate, and topography. Climate diversity has led to an interesting ecosystem in the country that each family of plant has its own genus and species. Plants are live creatures, and humankind is dependent on them forever because plants are the sources of food, oxygen, energy, main materials, and medicinal drugs. However, plants are not treated by us the same as animals. It may be because they do not show any senility as do animals [1]. Although such an ecosystem is of great importance for Islam Abad Gharb, natural habitats have been extensively destroyed by humankind in different ways, especially through agricultural activities, so many valuable species have vanished. However, a natural ecosystem can be seen in the region, yet researchers have had a less head to it. Islam Abad Gharb is located in Kermanshah [2]. It is bounded by Paveh and Gavanrood in the north, Sarpolzahab and Gillangharb in the west, Ilam in the south, and Kermanshah in the east. It is between 45, 24 min to 38, 30 min of the eastern longitude and 33, 36 min to 35, 15 min of the northern latitude. Its extent is about 4654, and it is 1335 m above sea level. It is a mountain city with an average annual rain of 414/72 m. The highest average temperature is 37°C in August, and the lowest average temperature is –20°C in December.

Materials and Methods

To introduce the regions’ flora, plants were collected from different regions from early march to late June in 2014. In this investigation, perfect samples were used and all vegetative samples, after the preparation of herbarium, were investigated in Payamenoor’s herbarium and the herbarium of the agricultural faculty of Razi University; their identification was done after being fixed on herbarium sheets.

- Yazd flora [3], Iranica flora [4], herbal plants [5], names of Iranian plants dictionary [6], and plant ranking [7], Iran’s chromophytes [8], Iran’s astragalus [9].

- Iran’s flora, butterfly-shaped family, Kermanshah flora.

- Application of Lu method—phytosociology in the determination of intergenus [10].

- Introduction of growth flora in the drainage basin of kerned [11].

- Introduction of 72 eatable plants in Kermanshah and Kordestan [12].

- Iraq flora [13] and Turkey flora [14].

- Introduction of flora and determination of the biological shape of growth elements [2].

- Common code of families and genus of Iran’s flora [11].

- Investigation of the flora of Dalaho mountain in Kermanshah [1].

- Iran’s weeds [15], herbal plants [5], Europe‘s flora [16].

Raunchier ranking was used for the determination of biological shapes [10]. This ranking is based on the unpleasant condition for growth.


Floristic investigations showed that in the region of study, there are 79 families, 255 genera, and 335 species. The families have the most diversity are Composite (29 spp.), Brassicaceae (28 spp.), Gramineae (27 spp.), Papilionaceae (26 spp.), Apiaceae (24 spp.), Labiateae (17 spp.). The results showed that the Composite family has the most diversity of all (Figure 2).

Moreover, the floristic investigation in the region show that the subspecies of Acer monspessulanum L. grow in all the growth regions of Zagrous, including western Azarbaijan, Kordestan, Kermanshah, Ilam, Lorestan, Gharmahal Bakhtiari, Isfahan, Kohgiluyeh and Boyerahmad, Fars, and Khozestan.

The largest genera in the region are Euphorbai (7 spp.), Allium (5 spp.), Trifolium (5 spp.), Convolvulus (4 spp.), Hordum (4 spp.), and Salvia (4 spp).

The percentages of biological shapes of plants in the region are: 47% (Therophytes), 24% (Hemichriptophytes), 12% (Phanerophytes), 10% (Geophytes), 30% (Chamaephytes), 2% (Hydrophytes), and 2% (Halophytes).

The geographical dispersion of the plants in the region is as follows:

Iranian-Toranian (54%), European-Syrian (30%), Sahara-Sydney (11%), and worldwide (5%).


The flora of the region has been investigated for the first time, and it was clear that the flora has 255 genera, 335 species, and 79 families. Composite (29 spp), Brassicaceae (28 spp), Gramineae (27 spp), Papilionaceae (26 spp), Apliaceae (24 spp.), and Labiateae (17 spp) are the most common. Euphorbiae (7 spp.) is the largest genus in the region, and the lowest growth shapes belong to: trophits (47%), Hydrophytes (02%), Halophytes (02%).

In terms of vegetative geography, Islam Abad Gharb belongs to Iranian-Toranian area, and it is confirmed by the results that show that more than half of the species (54%) are in this region. The comparison of chorotypes of plants in different habitats show that Iranian-toranian species increases with the increase in height while Sahara-Sandi species decreases. Among the trees and shrubs are Quercus brantii, Q. infectoria, Q. libani, var persica: Cratagus pontica, Daphne mucronata, Cerasus microcarpa subsp. tortuosa, Acer monspessulanum subsp., and Amygdalus orientalis subsp. orientalis.
