Forest Plantation Trial, Using Multipurpose Trees and Shrubs in Different Parts of Iran ABSTRACT Due to different economical and social factors, the influence of human being on forest and rangeland resources degradation is increasing. For this reason, using multipurpole trees and shrubs for forest rehabilitation, not only conserves soil and water and increases the local people income, but it encourages them to share in different programs for natural resources rehabilitation. The forest plantation will be made at rainfed condition or at low level of watering, using appropriate water catchment system. The research plan consists of two stages: 1- selection of different species varieties and provenances, seedling propagation, selection of superior varieties and provenances at nursery and estalibshment of varieties and provenances collection, and 2- Plantation trial of the superior varieties and provenances at field condition. Species selection depends on local economical and social circumstances and the people willing and interest. The seedlings selection and the forest plantation trial should be done under appropriate statistical design, based on number of treatments and site condition.
