| Abstract | Mangroves are important intertidal ecosystems typically in tropical and subtropical regions. Their restoration and conservation are important for the regulation of carbon fluxes and climate change control, also to maintain their valuable services for the coastal zone. The main goal of this study is to investigate the potential use of textural indices derived from a very high spatial resolution WorldView-2 image to estimate the aboveground biomass (AGB) of a mangrove forest in the Environmental Protection Area of Guapimirim (RJ, Brazil) subject to different levels of disturbance. Fourier-based Textural Ordination (FOTO) (Couteron, 2002, Proisy et al. 2007) and Grey-Level Co-occurrence Matrix (GLCM) (Haralick et al. 1973) textural indices were extracted from the panchromatic optical image. An accurate map of AGB was derived from lidar data and this map was used to train and test Random Forest, and AutoPLS methods to estimate AGB. The textural variability pattern associated with the canopy characteristics of the mangrove measured by FOTO and GLCM indices showed reasonable relationships with AGB. When many training points (from lidar) and both types of texture indices were used together the results improved markedly (RMSE (LOO) =25.64 t/ha, R²(LOO) =0.41). One source of uncertainty comes from the fact that degraded forests with low AGB values present coarse textures and can be confused with the textural pattern of high and more preserved forest characterized by large crowns. Our methodology can be applied to forests with different degrees of development but requires cautions for degraded forests for which texture gradients are not univocal. Nevertheless, the Random Forest classification based on the textural indices showed good results for the discrimination of different types of land cover such as non-mangrove, altered and preserved mangroves. Efforts such as those developed in this work are necessary to quantify AGB and carbon stocks, for monitoring purposes, as to assist public policies for the conservation and protection of these ecosystems. | |||
