Persian oak (Quercus brantii Lindl.) has a wide distribution in central Zagros forests and it is the prevalent species in this region. Considering the high volume of demolition and the importance of safekeeping of this jungle, investigation and knowing the structure and the situation of this forest from the qunatitative and qualitative aspects is necessary. This study accomplished to investigate the condition of the Iranian oaks (Quercus brantii Lindl.) forests from the qunatitativeand qualitative aspects of Bazoft district of Kouhrang township of Chahar Mahal and Bakhtiaris province. In this respect, 60 numbers of plots with 400 meter distance  in a randomize systematic method established in the area. Then in the studding plots the quantitativecharacteristics of trees like: dbh, trees high, crown diameter measured and some characteristics like canopy percent and firewoods were estimated and registered. Also qunatitative marks from 1 to 4 were given to the trees and they were recorded and data were analyzed. The results shown that the jungle wasa non- coeval and it was sparse forest. Also, 81% of the region had 0-25% coverage. The most density and firewood volume was observedin northeast direction. Also,75% of the trees were inthe proper degrees of Succulence. The results of this study showed the average and a suitable situation of study area stands in comparison to the other regions of central Zagros forests.

The aim of this research was study of tree species diversity in the Zagros forests of Iran that known as Ardal’s Chartagh protected forests. The total of the study area was 50 hectares. In this way 50 sample plots (circular shape with 1000m2) were measured based on systematic-random sampling method. In each plot species, DBH, species and number of trees were measured and recorded. To estimate of the tree species diversity, Shannon-Wiener, Simpson, Mc Arthur’s N1 and Hill’s N2 indices and for calculation of evenness and species richness Wilson- Smith’s and Margalef indices were used respectively. Also species importance value (SIV) was calculated. The results showed that there are 7 tree species in the study area including Fraxinus rotundifolia Mill., Juniperus polycarpos C. Koch, Cerasus mahaleb (L.) Mill., Quercus brantii var. persica, Pistacia mutica Fischer, Acer monspessulanum subsp. cinerascens and Salix persica Boiss.. Values of Shannon-Wiener, Simpson, Mc Arthur’s N1 and Hill’s N2 indices are 1.23, 0.58, 2.40 and 2.16. Also Wilson- Smith’s and Margalef indices showed that the values of richness and evenness are about 0.84 and 0.77. The results of SIV showed that the highest value of SIV belonged to the Fraxinus rotundifolia Mill. (188.63%) and the lowest value was due to Salix persica Boiss (17.59%). Therefore, conservation of forest stands might be suggested as a suitable approach for increasing plant diversity.

Morphological characteristics of individuals are due to hereditary and environmental factors. Regarding to the importance of leaf morphology in systematics investigations and bearing up the effects of environmental variations, especially altitudinal variations on these traits, the differentiation feasibility of brant oak in a restricted altitudinal gradient is investigated. A total number of 400 leaves from 40 individual ramets in Armarde, in an altitudinal ranges from 1580 to 1844 meters above sea level were sampled and 29 quantitative and qualitative traits were measured. The results revealed that the number of teeth and the shape of leaf at lower altitudes are lesser than higher altitudes. Also, leaf base angle has a negative and significant correlation with the altitude. In two altitudinal classes, the shape of leaf tip and the angle of midrib and vein, showed the lowest plasticity and coefficient of variation with respect to environmental conditions. Ramets were classified in three different classes based on cluster analysis and the separator traits were the maximum leaf width, leaf area and sinusoidal angle. Considering the fact that the separator traits would not showed any significant association with altitude,  it seems that some variations might be likely due to physiological response of leaves to environmental variations. However, itchr('39')s more likely that the occurrence of inter and intra specific hybridization between brant´s oak species would culminated in separation of the individuals.
