The book compiles scientific literature and provides approaches for construction of tree growth models. It presents an updated source of references for students, researchers and practitioners requiring current process of research and methods in the field. The book describes current modelling approaches for predicting forest growth and yield comprising various modelling approaches. It gives the readers with the tools for evaluating and calibrating growth and yield models and outlines the required steps for developing forest growth and yield model. The book starts by Introduction and a brief account of sampling techniques and experimental design followed by whole-stand, size-class and individual-tree approaches for modelling forest growth and yield. It is ideal for use in forestry courses and provides ready access to a plethora of reference material for researchers working in growth and yield modelling. Contents: 1. Introduction 1.
