1Over-mature beech trees (Fagus orientalis Lipsky) and close-to-nature forestry in northern Iran显示文摘Oriental Beech is the most important commercial tree species in northern Iran. In recent years wood production companies interested in felling large beech trees for profit have challenged advocates of close-to-nature silviculture who favor conservation. Our study objective was to assess the economic value of over-mature beech trees by relating tree diameter (DBH) to amount of decay. Based on the location of onset of decay, we categorized three types of decay as stump, stem, and crown decay. Trees of greater diameter (age) typically showed greater decay in the stem. Percent of decayed volume, diameter of decayed tissue, and length of decay in tree stems varied between 0.5%?64.3%, 15 cm?75 cm, and 2.0?19.5 m, respectively. With increasing trunk diameter, the proportion of truck decay increased. Red heart and dark red heart constituted 25% and 14.3% of sampled trees, respectively. However, we found no correlation between intensity of stem decay and morphological characteristics of trees. Seedlings were not abundant around the bases of over-mature trees, suggesting that the trees did not contribute to regeneration of the stand. Beech trees of diameter >1 m do not provide valuable round wood for industries and cause to raise wood production costs. We recommend that these trees >1 m DBH should be retained in forest stands because of their low commercial value but high ecological and conservational values such as maintaining biodiversity in forest ecosys-tems.Mostafa Moradi Mohammad R.Marvie Mohadjer Kiomars Sefidi Mahmoud Zobiri Ali Omidi 2012Journal of Forestry Research2012,23,2:5
2伊朗法尔斯省Poshtband地区植物的生活型和地理分布(英文)显示文摘在Postband地区(27°58′4″-28°2′16″N,53°17′34″-53°22′30″E),辨别植物种、植物多样性、生活型及地中海气候、Irano-Torunian和撒哈拉-新店相关植物种。2008年6月至2006年12月间,调查和辨认了29个科,69个属,总计95个种。就物种频度而言,菊科和禾本科是重要的科。按照Raunkiaer's生活型谱系统和利用■2检测,生活型谱表明,年生植物、地面芽植物、高位芽植物、地上芽植物和陷芽植物分别占据全部植物种的47%、31%、12%、7%和3%。在地理分布上,Irano-Torunia地区,拥有最高的频度的29%的物种。结果表明,一年生植物比生活型基准群谱高;高位芽植物比生活型基准群谱低,这与在干旱地区的研究数据相一致。图1表4参50。Gholamhosein Moradi Mohammad Reza Marvie Mohadjer Ghavamodin Zahedi Amiri Anoushirvan Shirvany Nosratollah Zargham 2010Journal of Forestry Research2010,21,2:2

4Effects of grazing on natural regeneration of tree and herb species of Kheyroud forest in northern Iran显示文摘We investigated the effects of grazing on natural regeneration, quantity, and diversity of woody species and dominant herb species in Kheyroud forest in northern Iran. We sampled vegetation in 5m2 plots in custom units, which are demarcated resource areas traditionally used by local livestock producers. The authors quantified number of species, height of seedlings, and diameter of seedlings. Height classes were 0-30 cm, 30-130 cm, and >130 cm, and diameter classes were 0-2.5 cm, 2.5-5 cm and 5-7.5 cm. The density of seedlings declined with distance from corral until reaching the custom unit boundary. Most seedlings had diameters of 0-2.5 cm and heights of 0-30 cm. Predominant species, Carpinus betulus and Acer capadocicum, were in plots near the centers of custom units, Fagus orientalis, Acer velutinum, Quercus castanifolia species were dominant in plots near the custom unit boundary. Plant species such as Oplismenus undulatifolius, Euphorbia amygdaloides, Rubus fruticos and Pteridium aquilinum were dominant in plots nearer to forest corral. Healthy seedlings were more numerous in plots nearest the corral, while defective and deformed seedlings were more abundant away from the corral. We conclude that grazing had negative effects on the quantity and quality of vegetative regeneration. Continuation of overgrazing will not only endanger the sustainability of forest ecosystems, but also will increase the challenge of sustainable forest management.Mohsen Javanmiri Pour Mohmmad Reza Marvie Mohadjer Vahid Etemad Mahmoud Zobeiri 2012Journal of Forestry Research2012,23,2:1

12Natural regeneration of oriental beech(Fagus orientalis Lipsky)trees in canopy gaps and under closed canopy in a forest in northern Iran显示文摘For developing nature-based silvicultural practices in a beech forest to promote, abundance, height,vitality, and preferred growth form, regenerated trees growing in gaps were compared with those under closed canopies.A systematic 50×50 m grid was plotted in a beech stand in the Kheyrud Experimental Forest for selecting trees to measure variables in gaps and under closed canopies.Abundance and mean height of regenerated beech trees were significantly higher in closed canopies than in canopy gaps.Beech seedlings with excurrent growth were significantly taller within regeneration patches under closed canopy.Moreover, regenerated trees with high vitality were more abundant in closed canopy areas than in gaps.Thus, beech regeneration should improve under closed canopies; hence, gaps in a near natural forest should be created only after adequate regeneration and appropriate growth under the parent tree in a closed canopy area is ensured.The results of this research have profound implications for the sustainable management of the forest and for ensuring sustainable beech regeneration.The presence of a closed canopy cover likely will reduce potential stresses on oriental beech regeneration.Nasrin Nasiri Mohammad R.Marvie Mohadjer Vahid Etemad Kiomars Sefidi Leila Mohammadi Maryam Gharehaghaji 2018Journal of Forestry Research2018,29,4:1
