Habitat conditions Study of Myrtus communis L. in forests reserves of Ilam province

The most important habitats of Myrtus communis L. in order to study habitat needs located in Tanoreh Abdanan, Zarab Zarinabad and Mort village from Chavar district in year 2013. Then variables such as crown diameter, shrub height, vitality and number of regenerations were measured by 100% inventory method in three regions. Also, three soil samples were taken from each site and pH, Electrical Conductivity (EC), Organic Carbon (OC), Nitrogen (N), Phosphorous (P), Potassium (K), Bulk Density (BD) and soil texture parameters were measured in the lab. By Using the SPSS software v.16, mean comparisons of edaphic and vegetative parameters in three sites were performed. In this study, correlation analysis between different parameters was investigated and the regression model of correlated parameters was built in separate for each site. Results showed that there is a significant difference between all parameters in three sites. Also, results revealed that there is statistically a positive relation between crown diameter and shrub height. Furthermore, in Chavar site, tree regeneration has a positive relation with soil OM and K. according to obtained results, in Abdanan site, there is a negative correlation between stems height and soil pH.
