Forest extent and significance
The hara forest on Qeshm and the opposite mainland covers an area of approximately 20 km by 20 km, with many tidal channels. The traditional stock breeders of Qeshm Island used the leaves of the hara tree for feeding livestock. In 1972 the Hara Protected Area was established to preserve suitable conditions for the growth and maintenance of the forests.The area is a major habitat for migratory bird
