In the Federation of Bosnia and Herzegovina, about 125,190 ha, or 10 per cent of all categories of forests and forestlands, are known or presumed to have been mined. The Forestry Development Strategy of Republika Srpska also indicates that 10 per cent of total forest area is affected by mined areas. The actual mined areas are probably slightly lower as much wider areas are demarcated as under mining for security reasons. These areas create safety and environmental problems and economic loss.
