A natural woodland unit which consists of all plants, animals and microorganisms in that area functioning together with all of the non-living physical factors of the environment is known as a forest ecosystem. Forest ecology is a diverse and important branch of ecological study, where trees are studied along with other elements, such as wildlife or soil nutrients. Trees contain a large amount of water and are considered to be important regulators of hydrological processes. Therefore, study of the forest ecosystems is closely related to resource planning studies along with meteorological and hydrological studies. The measure of the ability of a particular species to compete with other species in a given geographical area is known as ecological potential. It is a major focus area of this discipline. This book provides significant information on forest ecology and the functioning of a forest ecosystem. It consists of contributions made by international experts. Those who are in search of information in order to further their knowledge will be greatly assisted by this book.
