Forest health and protection

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.

Climate change and forest health

Climate change represents an unprecedented challenge to the world’s biosphere and to the global community. It also represents a unique challenge for plant health.

Forest invasive species

The global movement of people and products facilitates the spread of invasive species worldwide. They may often be unintentionally introduced through movements of goods and human activities (travels).
