Efficiency Study of Ellenberg method Application for Ecological Evaluation of Herbal sites (Case study: Ecological Evaluation of Lilium ledebourii site in Gilan Province)

This study has been done based on using of Ellenberg method for ecological evaluation of Lilium ledebourii site in Damash heights. Application of Ellenberg method as one of the ecological evaluation method for determining ecological parameters such as: light, latitude, temperature, soil moisture, soil fertility and soil pH is based on vegetation recognition and Ellenberg table application. Determining of vegetation in natural site is used as a tool for ecological evaluation of herbal sites. In this research a simple method of Ellenberg is applied for ecological evaluating of herbal sites and validity of method in compare with field investigation was studied. Ellenberg method results Comparison with field investigation show that this ecological evaluation method is valid arising from relative agreement between results. By applying of this method and understanding effective ecological factors on Lilium ledebourii, the conservation process of this threatened species should be upgraded.
