Mitigation of atmospheric pollution has been a topic of concern over the past decades. In this study, tree rings have been used to reconstruct past climates as well as to assess the effects of recent climatic and environmental changes on tree growth. Vehicular emission is one of the major sources of pollutants in the atmosphere and this study focused on the Haatso-Atomic road which over the yea...

ABSTRACT- To study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in Badjgah, Fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). In each pl...

Trees have been affected by environmental changes, including climatic conditions. Thus, the study on anatomical and morphological characteristics of tree rings provides the possibility of climate study. The present investigation aimed to study the effect at climatic factors such as temperature (maximum, medium and minimum), precipitation on the growth rings of Pinus brutia. 30 Pinus brutia tree...

Cornalian cherry (Cornus mas L.) is a native woody species in Arasbaran, N.W. Iran. It commonly grows as a wild tree on the forest edges and in forest openings areas. In this study, the influence of physiographic and environmental factors such as aspect, climate (temperature, precipitation) and physical and chemical properties of soil on the tree ring width of Cornalian cherry was examined and ...
