Forestry

Sustainable, well-planned, near to nature forest management deals with the production of raw timber. The classical central disciplines are silviculture, forest growth and yield and forest planning supplemented by information on the timber market, storage and bio-energy. Loss events, such as windfall, bark beetle or game damage, present an ever re-occurring challenge to forest personnel. Successful management in avoiding and limiting risks and damage is part of an effective operational strategy.
