Abstract

The present study includes the examination of Binaloud mountain range southwestern slopes north of Neishabour with an area around 500 km2 covering town of Kharv and Baghshangach village and the areas between them from floristical point of view. The altitude of the area ranges from 1300 to 3500m, the mean annual rainfall is 239.9 mm and the mean annual temperature is 14.25°C. The area comprises 487 plant species and subspecies belonging to 299 genera and 67 families. The largest families in the studied area were Asteraceae with 71 species, Poaceae with 50 species, Fabaceae with 45 species and Brassicaceae with 30 species, respectively. Therophytes constituting 37% of the biological types are dominant, followed by hemicryptophytes and chamephytes with 34% and 12%, respectively. From the standpoint of vegetation types, 48% of the chorotypes belong to Irano-Turanian vegetative elements and the rest relate to one, two, three or various other vegetation regions or have a global distribution. Based on the type of vegetation, type of basin and accessibility to water, the habitats can be divided into flat plains, rocky-dry slopes, wet slopes, aquatic habitats, landslides and degraded-land habitats.
