Forest health
1. The importance of pests and their negative impacts on forests are often underestimated. Pest outbreaks can contribute either directly or indirectly to economic and environmental losses. Insects and diseases can have adverse effects on tree growth and survival, yield and quality of wood and non-wood products, wildlife habitat, recreation and scenic and cultural value. Yet they are integral components of forests.
2. Invasive plant species can also cause damage through competition and prevention of regeneration of native tree species, posing new challenges especially to the in situ conservation of forest biological diversity. Pollution is another threat to forest health and vitality.
3. Insects and diseases influence the health of natural and planted forests, trees also outside forests and other wooded lands. Movement of insects and diseases has been facilitated by increased long-range air travel and reduced travel time, increased international trade of agricultural and forest products, and the exchange of plant material. Forest pests can be extremely destructive, as seen in recent years in both developed and developing countries.
