A brief description is given of the physiography, climate, and natural vegetation, of Iran. Subsequently an analysis is made of the environmental problems which are building up to crisis proportions. Of particular concern is the alteration and destruction of natural ecosystems through the impact of Man over a period of many centuries. As a result of H. I. M. the Shahanshah's personal attention to this problem, forests were nationalized, range improvement measures have been instigated, and the Department of the Environment has undertaken a comprehensive programme of conservation and management of areas of national importance.

A programme of scientific investigation and management of wildlife resources has been initiated. Intensive studies of Wild Sheep, gazelles, and Persian Ibex, are now under way. In all reserves the condition of the vegetation is closely monitored. Due to these measures, wildlife populations have increased in most reserves. Iran has some of the finest wetlands in south-west Asia, and has made much progress towards their preservation, over one million hectares of the most important wetlands being now fully protected.

The Department of the Environment has had considerable success in its programme of protection of endangered species—including the Onager, the Persian Fallow Deer, the Asiatic Black Bear, the Asiatic Cheetah, the Marsh Crocodile, the Great Bustard, and the Caucasian Black Grouse. The future of these species is now almost certainly ensured in national reserves.

Iran now has four categories of reserves: National Parks, Protected Areas, Wildlife Refuges, and National Nature Monuments. Thirteen National Parks have recently been approved. Currently there are 27 Wildlife Refuges. An extension of this network of national reserves is planned within an international framework.
