Abstract :

Medicinal plants as a none-woody forest products in each region, are valuable resources of related ecosystems that we can,t extraction its activate substance in other places. Oriental Currant shrub, ( Ribes biebersteinii ), is a valuable and infrequent shrub of Arasbaran and due to its interesting medicinal cares,has been received attention by rural people and around counties Spicer markets. Therefore the present study was prepared with the objective to investigation of effective ecological factors in distribution and settlement of Oriental Currant as a medicinal shrub in Arasbaran forest, Mardanaghom-chay watershed. For achieve to this aim, vegetation coverage in different strata with environmental characteristics was recorded in plots. For chemical & physical characteristics of soil, soil samples were taken from under organic layer from 10-20 centimeter depth. Floristic and environmental data was analyzed with Ordinations approach CCA (Canoncial Correspondence Analysis). Correlation analysis results showed that under studying specie, has positive and strong correlation with Sand rate in sub-soil and region. Preference to Loamy with suitable drainage soil can be seen, but showed negative correlation with sub-soil acidity and clay percent. Cultivation & Developing of native medicinal plant species in the region, as none-woody forest products, will be notifiable solutions to reduce rural people and foresters unsuitable pressure on forest ecosystem.
