What is Modeling litter mass using satellite NDVI images and environmental variables in a brutian pine forest located in the southwest of Turkey about?
Litter mass (LM) on the forest floor is an important component of the carbon (C) cycle in forest ecosystems. A considerably amount of LM is accumulated in the conifer forests in the Mediterranean Region of Turkey. Therefore, LM should be considered to estimate above ground biomass (AGB) more accurately in these forests. Rapid and affordable methods are necessary for LM inventory. Satellite remote sensing data and GIS-based environmental variables, which cover broad geographic regions, are alternative data sources in this scope. In this work, the LM was modeled by means of generalized additive model (GAM) using the predictor variables including the Normalized Difference Vegetation Index (NDVI) images (derived from RapidEye, SPOT-5, Aster) and environmental data (heat index-HI and radiation index-RI). According to the cross validation test, the best model using NDVI ASTER and HI as predictor variables explained a total variation of 49% of the LM as response variable. We may conclude that the LM on the floor of brutian pine stands can be moderately predicted using satellite data and environmental variables. We consider that the results of this study may contribute to estimation of AGB
