Volume 4, Issue 2 , Spring 2018, , Pages 207-216

http://dx.doi.org/10.22034/gjesm.2018.04.02.008

Abstract
  In this study, to investigate the effects of runoff harvesting on soil properties in the semiarid forest, runoff harvesting through semi-circular bund was considered as a method to conserve soil and thereby combat tree mortality. In order to evaluate this hypothesis, runoff was harvested through the ...  Read More

F. Taleshian Jeloudar; M. Ghajar Sepanlou; M. Emadi

Volume 4, Issue 1 , Winter 2018, , Pages 59-70

http://dx.doi.org/10.22034/gjesm.2018.04.01.006

Abstract
  Vulnerability of soil separates to detachment by water is described as soil erodibility by Universal Soil Loss Equation which can be affected by land use change. In this study it was attempted to quantify the changes of Universal Soil Loss Equation K-factor and its soil driving factors in three land ...  Read More

5. Leaf size indices and structure of the peat swamp forest

L.G. Aribal; J.G. Bonggay; E.S. Fernando

Volume 3, Issue 1 , Winter 2017, , Pages 63-74

http://dx.doi.org/10.22034/gjesm.2017.03.01.007

Abstract
  Leaf size indices of the tree species in the peatland of Agusan del Sur in Mindanao in Philippines was examined to deduce the variation of forest structure and observed forest zonation.  Using raunkiaer and webb’s leaf size classification, the leaf morphometrics of seven tree species consistently ...  Read More
