From: Model performance of tree height-diameter relationships in the central Congo Basin
Height-diameter models for the studied region, namely, the local model (orange) and the mixed effects local model with site-specific deviations for Yangambi (blue), Yoko (green), and Yambela (red). The regional models for central Africa by Feldpausch et al. (2012) (black dotted line) and Banin et al. (2012) (black dashed line) and the pan-tropical model by Chave et al. (2014) (full black line) are indicated
