بررسی تأثیر قرق همراه با عملیات آبخوا نداری بر روند افزایش طبیعی نهال های ارس Juniperus excelsa Bieb.(مطالعه موردی: مازندران- حوزه آبخیز پشتکوه)
Determination of suitable species is the most important factor in success of forestation in unfavorable conditions. One of the least costly and the shortest ways for introduction of adaptable species in an area is recognition of the plants that grow naturally. The objective in this study was to find out the effects of protection and water spreading operations on the quantitative improvement of ...

متن کاملResponse of two Afromontane coniferous tree species to light and nutrient supply.
We studied the responses to light and nutrient availability of the two Afromontane conifers Juniperus procera Hochst. ex Endl., reputedly a shade-intolerant species, and Afrocarpus gracilior Polger C.N. Page, a shade-tolerant species. The species behaved similarly in response to light and nutrient availability. Both species showed positive growth rates at photon fluxes of 0.6-0.8 mol m(-2) day(...
متن کاملEffect of Stand Structural Characteristics on Natural Regeneration of Acer Campestre L. in Arasbaran Forest
Natural regeneration is one of the key aspects of forest sustainability and a tool to decide on restoration programs in forest areas. The purpose of this study was to investigate the quantity of natural regeneration of Acer campestre L. as one of the most important tree species in Arasbaran forests and its relationship with elevation changes and structural characteristics in the natural stands....
متن کاملComposition and structure of a Fagus orientalis-dominated forest managed with shelterwood aim (A Case study in the Caspian forests, northern Iran)
Composition and structure of a three-storied Fagus orientalis-dominated forest was investigated in the Caspian forests, north of Iran. Circular sampling plots of 1000 m2 occupied by advance growth and natural regeneration were randomly chosen where the initial cuttings (with shelterwood aim) were performed. Abundance of species at different growth stages and quality of seedlings and saplings we...
