In every part of the Zagros forests, some trees and shrubs were established, such as Quercus brantii , Pistacia sp. Acer cineracencs, Celtis australis , Platanus orientalis, Fraxinus sp, Ceracus mehleb, etc.With different composition Bazoft – Tangehooti,because of special site condition , presents a uniqu stand of elm(ulmus boissieri). This research was carried out to recognize the site demands of (Ulmus boissieri) statistical studies for qualitative and quantitative factor were conducted for each of plants completely. The systematic statistic network (40*40 meter)was used tomeasure trees growth and study of herbs and shrubbasead on 100 m plots. For investigation of regeneration condition , microplots (10m) were used in main plots. This stands was weak and seniority, so phyllophagous and stemborer pest were exited in the site severely. Investigation of trees growth showed that minium,maximum and average of diameter increment were1.5, 3.4 and 2.1 mm in year respectively.Volum increment of the stand was 1.45 sylve per hectar.Dominant height of elmtrees was determined 1.54 m. Diameter distribution showed that this stand is more or less even age. Number of seedling for Ulmus boissieri and other trees species were estimated 7500 and 560 per hectar respectively. The suitable statistical model for relation between diameter and height of elm trees is calculated as: H=0.5147

Of 36 indigenous and exotic nurseries in Mehregan station and Gharb рарег industries in Kermanshah province, 18 clones of poplars, demonstrating highest beight and diameter as well as resistance to pests and diseases, were selected for further adaptabllity programs. Eight clones of populus nigra L. (with closed crown) bу ЗхЗ meters spacing and 10 clones of exotic hybrids (ореп crown) Ьу 4х4 meters spacing were studied in а randomized complete Ыосk design with three replictions (25 seedlings for each replication ). VariaЫes measured include: height (m), diameter at breast height (сm), and volume calculation (m3). Тhе results for а 7 year period e~aluation indicated Р. eura. 455 and Р. eura. 1-214 as the highest yield / hectare / year clones for 4х4 spacing and Р.n. 62.171 and Р.n. 63.135 for 3х3 spacing.

According to this project , we should plant 30 species and 61 provenances in each рап of Asdlem forest zone, regarding to the reason that we couldnt, plant all the species and provenances in the same time. So decided to plant them gradually and with different phases. The present article included three project at different three height zone in Gillan province. In Asalem forest at the height of lower zone 450 meter thats includes Seyabil project which called No 1 , 13 species and provenances have been cultivated and in the middle zone which is suitated in asalem forest in Nav project at the height of 1050 meter, 15 species and provenance have been cultivated , and in upper zone at the height of 1750 meter in N av project in Asalem species and provenances have been 9 cultivated . In each zon projects being evaluated througth Random Ыосk method with in randomize plot in three 2metre,in each plot we used 100 repeatation in а distance 2xsamples treatments in each plot. Distance between Ыocks and treatments is 3/5 metre. In this study some important factors like , annual surviral , annual height and collar diametre in evry five ye~rs being evaluated and in each treatment two side rows had been as а protector and 36 samples only in the middle parts of each plot evaluated. According to this assesment that has been completed shown, these Lower zone: Pinus nigra var. calabrica, France; Pinus nigra var. pallaziana, Turkey; Pinus taede, USA; Pinus ponderosa, USA; Pinus nigra var. austriaca, Austria; Pseudotsuga menziesii, USA (Oregon); Pseudotsuga menziesii, USA (California); Abies equitrojani, Turkey; Pinus sylvestris, Turkey; Pinus nagra var. austriaca, Austria; Abies nordmanniana, Turkey; Abies cilicica, Syria; Pinus nigra Var. calabrica, France; Pinus nigra var. pallasiana, Turkey; Upper zones: Picea abies, Iran (Kalardasht); Pinus sylvestris, Turkey; Pinus sylvestris, Spain; Larix leptolepis, Japan; Pinus ponderosa, USA; Pseudotsuga menziesii, USA (Oregon).

Limitation Natural Forest in the world and incressing of needs to wood production , result have had most attention to poplars. With attention to species various of poplars, it is disterbuted in different climatic condition of Iran.in the north Кhorasan аге Planted Poplars under tlraditional condition with species populus nigra and Р. alba. for the better known of poplars variets and it development , was accomplished design of poplar experimental in the natural resourses research station of north khorasan with titel collection and investigation various variets poplar. This experiment, endemic varietis include Populus nigra and Р alba were collected from north area of khorasan in during two years. Non endemic varietis were provided than research center of Alborz (Karaj) that аге included of following groups : Р. x.euramericana (1 lclones), Р. nigra (15), Р. deltoides (5), Р. simonii (1), Р. ciliata (1), Р. trichocarpa (1). In the primary year , is provided cutting from all clones and they were cultivated with distance 20 cm and was interval clones 1. 7m together , in this experimental , the following parameters were investigated; measurement, height growth and diameter growth in different ages (1/1,1/2,2/3)* determination of successful percentage cutting in different date of cultivation , effect cut the base of shoot оп the growth of tillers , uniformity of sapling growth and clones resistance to disease and pest. Among different groups of sapling with age (1\1), the highest growth are belonged to Р. nigra, Р. deltoides & Р. x.euphraticana groups. the most various percentage is registered for Р. cilliata and Р. deltoides groups, and lowest various percentage have to Р. nigra group. ln final of growth season from primary уеаг l1ad cut all sapling , and in secondary уеаг were investigated of sapling with age 1/2,than between total groups result, the highest ofheight growth increases, belong in Р. alba clones. in the third уеаг was measured of young tree with age 2/3, than the highest growth belong for Р. eur., Р. nigra (non endemic), Р. alba (non endemic) groups, that have not significant different in 1 % level together, but had significantly different with other groups. ln the total groups have not high sensitiveness in wood pest , but leaf pest, like Choitophorus populi and Monsteria discoidalis are estabished severely pollution оп the Р. nigra and Р. alba clones respectively and have had the highest resistance Р. deltoides clones. The disease melampsora populina have the most pollution оп Р. n 42/78 and 49/5 clones Р. ciliata clone have had the most sensitiveness to frost.
