| The success of the planted Alder (Alnus glutinosa) has been investigated in the east of Guilan province. The pure stands with 14 to 29 years old were planted close to 5.8 hectares (2 x 2 In). Studies were carried out on 61 plants and 619 testifier trees about quantity and quality aspects. The circle plots (857 - 961.5 square meters) were laid out with random- systematic method survey. The results indicate that the planted Alder (Alnus glutinosa) had the ability for plantation on Caspian Sea flat area for wood production. The necessity of wood increases day by day in Iranian economy, and trees can solve some of the problem.
