Forest health in a changing world
A healthy forest is able to sustain the species and processes that exist within it. However, across the world, abiotic and biotic disturbances are having major impacts on the health and vitality of forests.
These disturbances can impact tree growth and survival, yield and quality of wood and non-wood products, wildlife habitat and ecosystem services, as well as the recreation, scenic and cultural values of forests. Such impacts can result in substantial economic, social, and environmental loss.Highlights
