Identification, Collection, conservation and determination geographical distribution of trees and shrubs genetic resources in Makazi province

Recognition of plant genetic resources, investigation of ecological and morphologicalconditions, and determination of geographical position of the plant species as well asimplementation of research projects on conservation and protection of these resources with the use of different conservation techniques seem to have a special importance. In this research, geographical position and distribution of the trees and shrubs of Markazi province were determined with GPS and recorded in digital map as a segment with 1/50000 scale and then polygonized. Geographic information system (GIS) and ilwis academic software were applied on mapping the trees and shrubs species distribution with two types of polygon and point maps. All trees and shrubs of the province were listed. Several characteristics of the trees and shrubs species such as seed production term, multiplication, utilization, health, pest and disease were determined and registered. Finally, geographical distribution of 11 tree and shrub species wer determined and mapped based on their priorities, as: Pistacia atlantica, Pistacia khinjuke, Nitraria shobiri, Rus cororaria, Quercus persica, Amygdalus scoparia, Lonicer Nummulariifolia, Berberris Integrrima, Cerataegus Zsovitsii, Cerataegus Pseudoheterophylla,Creatagous Atrosanguinea. The results showed that trees and shrubs are crowded in 40geographical areas and distributed individually in various and many parts of the Lorestan forest regions and among them most of the area is covered by Amygdalus scoparia species.
