Abstract

In the near past, OAK FORESTS of YASUJ were covered by countless trees and other plants, but at present, owing to increase in human population, excessive grazing by domestic animals, deforestation and excessive use of trees and plants, expansion of agricultural lands and construction etc. their appearance has completely been changed into ruined forests. With the exception of areas out of human of animal reach, in other areas the forest has been intensively damaged and one can only see solitary crooked trees and scattered groves. The present research is a situational analysis of forests of the region in the past and present and an assessment of the traces and manner of destruction and a comparison of the past and present destruction and encroachment by man and animals: Therefore, an assessment of increase in human and live - stock population in the area and its impact on the destruction of these forests has been undertaken during the last 34 years (during two periods of 14 and 20 years) through aerial photographs of Zagros montainous areas located in the north-west of Kohkiluye va Boyerahmad province (Pataveh region) during 1955, 1969 and 1989. An estimation and comparison of the percentage of different types of land areas along with estimation and comparison of the percentage of different types of forest areas with varying grades of density from the viewpoint of coverage percentage during the above time periods have explained, controlled and assessed. Meanwhile, a qualitative and quantitative assessment of the present situation of the forests of the region with the provision of a systematic statistical network, and a study of the socio - economic situation of scattered hamlets in the forests and of the ribal and rural farmers and of the way of benefiting from the forest has been undertaken through a questionnaire. In view of the photographs taken during different periods of time, the findings of the assessment of the past situation of the forest indicate that as a result of direct destruction of forest by man and live-stock. The forest areas are constantly decreasing and the areas of arable and agricultural land are increasing. In fact, this reduction has an upward trend, for in 1955 around 78.2 per cent of the area under study was covered by forest, which in 1969 and 1989 decreased to 74 and 60 cent per cent respectively. During the above time lapse, the land covered by dense forest has been changed into less dense forest. The findings of the assessment of the present situation of the forests of the area indicate that as a result of deforestation and excessive exploitation, the situation area indicates that as a gradually deteriorating. Most of the trees have a ramification of branches with crooked and non - industrial firewood trunks. The average number of trees per hectare is 91.2 with 30 to 50 per cent crest coverage and the height of trees is 6 to 12 meters with 7 to 60 cm. diameter. The diametrical dispersion of trees is mostly of the diametrical categories of 10 to 30 cm. On the margins of the villages, as a result of cutting and excessive exploitation, the forests have been intensively damaged and due to perennial grazing of animals and their presence in forest area, the regeneration process of trees has been reduced.
