Myrtus communis is a pharmaceutical and industrial plant which has been overexploited and diminished due to environmental pollutions as well as consecutive droughts in Fars province. To maintain a better conservation of this species in its natural habitat, ecological studies were carried out in each region, plant specimen from four typical climatic zones including Nourabad-e-Mamassani, Firouzabad,Fasa and Darab were provided and collected and were analyzed and tested with regard to composition and the amount of constituents and the best time of leaf and branch harvesting. Also, in Sarab-Bahram stations, Nourabad-e-Mamassani, different ways of establishment of this species (seed, cutting and sprout) were studied. The results showed that in Darab and Nourabad-e-Mamassani regions, the amount of - Pinene and 1,8- Cineole in lowest in spring and highest in the summer. On the contrary, Limonene and Linalool quantities are highest in spring and lowest in the summer. Compositions such as Camphen, an important pharmaceutical agent, were also considerably high in spring in Firouzabad and Fasa (%6.1 and %6.9, respectively), and some compositions such as Neryl acetate were not found in Darab. In respect to the rehabilitation of Myrtus habitats, results showed that considering the frequent droughts in Fars province, planting seedling is more desirable than other methods and all planted seedlings have continued to grow.
