Conservation of genetic reservoirs particularly genetic resources of forest trees and shrubs is one of the economic, scientific and social necessities of people and governments. Some factors such as non scientific and extra exploitation have caused that these vital and priceless resources to be in danger, vulnerable or overthrown situation. So it will be very difficult or impossible accessibility to them in the future. Now it is an obligation that these genetic resources prior to damage and destruction are identified, collected and maintained in a best condition for future utilization. There was carried out a research project in order to recognize and collect the seed of forest trees and shrubs in Hormozgan province. In this research, primarily the results of some studied projects in the various fields afforests were collected, surveyed and checked by circulation in the forest areas. Fifty two species of forest trees and shrubs were identified. Most of these species is very important in respect of ecological, economical and medicinal use. Thirty six species with priority of vulnerable, indenger, rare condition were recognized as below. Acacia nilatica, Acacia oerfata, Acacia ehrenbergiana, Prosopis farcta. Prosopis cineraria, Juniperus excelsa, Pistacia atlantica, Pistacia Khinjuk, Ziziphus spina-christi, Periploca aphylla, Leptadenia pyrotechnica, Amygdalus scoparia, Acer monspesulanum, Ephedra foliate. Dodonea viscose, Myrtus communis, Daphnea oleoides, Astragalus fasciculifolius. Seed samples collected on branches of selected trees and shrubs and afterward they were dried in proper condition. There were collected a number of seed samples for any preferred species which are distributed in a vast region in the forest. At the end, 304 seed samples (200 to 300 gr.) had been sent to natural resource gene bank in of Research Institute of Forests and Rangelands of Iran. These tree and shrub genetic resources will be available for researchers to study them from different aspects now. Keywords: Identification, collection, conservation, Tree, shrub, genetic resource.
