Forest management is carried out with the greatest possible care and in accordance with specifically defined criteria of sustainable exploitation. The methods applied are also designed to prevent the bark beetle from spreading to adjacent forest plots.
The working methods to be applied (tree removal by tractor, winches or manually) are defined by nature protection and forest and wildlife management officials in joint field surveys. The forester implementing the measures must observe the requirements set down in the forest management plan. A check list of criteria for sustainable exploitation is used to identify sensitive structures and special features worthy of protection prior to the commencement of work. The key criteria include:• environmental protection and landscape preservation (careful handling of lubricants and fuels,...)
- preservation of remaining stock (no tree wounds,...)
- conservation of special features (wetlands, nesting sites, breeding areas,...)
- preservation of young stands
- soil conservation
- deadwood (should be left on site with the exception of infested wood,...)
Bark Beetle Control
Active forestry measures are currently taken only in the event of spruce bark beetle infestation, i.e. attack by Ips typographus and (less frequently and usually at lower elevations) Pityogenes chalcographus. Both bark beetle species tend to spread explosively under favourable conditions. The Forestry Act may therefore require active control measures to be taken, in particular where adjacent production forests and forests with a protective function for infrastructures and buildings are in immediate danger of being affected.
The forest management plan involves carrying out a risk assessment of the affected stand and taking preventive measures, if necessary
