There is increasing pressure on the forestry industry to adopt sustainable practices, but there is 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 both plantations and natural forests in boreal, temperate and tropical biomes. The contents have been developed from papers presented at a IUFRO conference held in Australia, August 1998.
