Abstract

Valonia oak (Quercus aegilops L.) is the dominant tree species in Kurdistan Region of Iraq. It covers the landscape of the region’s mountains and has an important role in the life of rural inhabitants besides its vital environmental protection functions. This species tends to develop a decurrent growth pattern, therefore, its wood is distributed over tree trunk and tree branches. As the wood of these two components is utilized for different purposes, separate equations were developed to assess the volume of each component in addition to the total volume. Furnival Index was utilized to select the best equation for estimating volume of each component. The selected equations were then examined to ensure that the error term is homogenous, normally distributed, and not autocorrelated. Finally, one entry and two entry volume tables were constructed for each component and for total volume
