Abstract :

The study of the flora of each region important in the management and development of natural resources and the list of plants represents of vegetation cover and environment condition. The present study was carried out in Dezli region in Sarvabad county of Kurdistan province with a total area of 12493.97 ha and mean annual precipitation (30 years) of this area was 804 mm. In order to introduce the flora of the area, field survey was used and plant species were collected and identified based on available Flora Life form and chorology of plant species were also determined. The results showed 113 species in 90 genera and 31 species in the region. The most important families were, Asteraceae (18 species and 17 genera), Poaceae (19 species and 15 genera) and Apiaceae (10 species and 9 genera). Life forms of plant species included, hemicritophytosis 47%, tetrophytes 30%, cryptophytes 12%, chamaephytes 7% and phanerophytes 4%. The high percentage of hemicritopathitis species indicated that the area had Cold mountainous area. The highest. Proportion of chorotypes belonged to Irano-touranian elements (67%). Also, 13% of the species had a European-Siberian pattern, as well as Mediterranean, 5% cosmopolitan were 12% and 5%, respectively, and 3% was endemic species of Iran.
