Indicator plants are the easiest instrument to understanding ecological conditions in Environment. This research investigates indicator plants species in six natural site of endangered species Populus caspica Bornm. In three Northern provinces of Iran with two goals; evaluate the current status of these habitats and indicator plant performance in the expression present status in habitats. Sampling was preformed systematic randomly with 100*150(m) sampling network and sample plot with an area of 400 m2 (20*20) and 9 microplot with an area of 4 m2 (2*2). Floristic list of all plant species were provided and Indicator plants species were identified with referring to the valid research and studies. Fundamental climate parameters (mean annual precipitation, annual temperature, etc. ...) and habitat characteristics (soil, destruction) were evaluated to assess Reagent indicator plants. According to the results, representing a total of 43 species was identified. There destroyed indicator plants, indicator plants of alkaline and poor acidity soil and Wetland Indicator plants are most striking feature of Populus caspica habitats. Humid and semi-humid climate, calcareous soil and widespread destruction were the most striking features of this endangered species site in Hyrcanian forest. Overall results of this study confirm the efficiency of valuable Indicator plants in the expression ecological conditions of habitats showed necessity of applying Indicator plants in biological resources management and advises considering the most effective and efficient arrangements ex situ and in situ management to restore and preserve these archaeological and endangered species sites.
