Summary
This study was carried out on the data obtained from 35 plot areas selected among the vertical distribution regions of maquis in study area located in Eastern Mediterranean region. The data were grouped in terms of altitude, domi­nant exposure, vegetation height, and mean age factors, and it is tried to reveal the change of maquis biomass depending on these factors. The data obtained shown significant variation and, for this reason, the mass values are expressed as mean values. The potential relationship between the mentioned factors and the amounts of stored bio­mass was examined by using t-test and variation analysis. The mean aboveground biomass amount was found to be 24,183 ton/ha, while mean belowground biomass that doesn’t contain fine root was found to be 41,062 ton/ha. According to these results obtained from mean values, the root/shoot ratio was calculated to be 1.7.
KEY WORDS: Biomass, maquis, root/shoot ratio, altitude, exposure
INTRODUCTION
UVOD
Maquis is a concept that has entered into vegetation science from the word „maquis” in Corsican language. The „shrubs, which are generally always-green and dominated by hard-leaved species, that are 2-5m in length in Mediterranean Basin” are named maquis (Özalp 2000). Scrub populations called maquis have significant role in agro-silvo-pastoral systems having limited water potential, and they have also potential to reduce the effects of climate change by acting as a carbon pool because of their high portion within the vegetation in places, where they spread over (Ruiz-Peinado et al. 2013). Besides being a carbon sink and containing high-level of biodiversity within their structures, maquis populations also serve for many traditional purposes such as providing feed in animal husbandry, firewood, and hunting (Nair et al. 2009, Canteiro et al. 2011, Varol and Ertugrul 2015).
