Book excerpt: There is increasing pressure on the forestry industry to adopt sustainable practices, but a lack of knowledge about how to facilitate this, and how to measure sustainability. This book reviews current thinking about scientifically based indicators, and sustainable management of natural forests and plantations. Information is applicable to boreal, temperate and tropical biomes. The contents have been developed from papers presented at a IUFRO conference held in Australia, in order to develop a state-of the art report on this subject.
