In the initial period of colonisation of the territory of today's Slovenia, people started clearing forests in the lowlands and on hillsides by means of the slash and burn method and hoe-farming. For long periods of time, large areas of less fertile, rocky and steep parts of the landscape were used as facilities for leaves and litter, while the high mountain regions were used for mountain pastures. As a consequence, the natural forest line was lowered.
Since 2008, the majority of deforestation has been a result of the construction of infrastructure facilities such as motorways, power lines, buildings and other facilities (stone quarries, landfills, refuse pits). In 2008 there has been an extraordinary increase in deforestation because of agriculture, such surfaces represent nearly half of the deforestated area. The majority of deforestation is approved; however, every year, a certain percentage (under 5%) is carried out without the authorization of responsible institutions.
In the Act on Forests, deforestation is defined as removal of all forest trees and other forest vegetation due to a change in intended use.
The manner of identifying deforestation areas is defined by the Rules on the forest management and silviculture plans. The inventory of deforestation was made based on evaluations and the planned range of spatial interventions (from planning and project documentation).

In the draft National Forest Programme, the following policies have been adopted:
• To allow deforestation if it does not pose a vital threat to the ecological function of the forests or if the public interest outweighs the ecological significance of the forests.
In this spirit and based on the Act on Forests and the Forest Development Programme, the following guidelines relating to deforestation have been developed in the Forest Management Regional Plans (2001 – 2010):
• It is vital to prevent unauthorised deforestation for agricultural purposes in agricultural and urban landscapes
• It is especially necessary to prevent deforestation of the upper forest line.
• To regulate forest grazing and limit it to enclosed pastures if possible, and reactivate the (overgrown) pasture areas instead of clearing new ones. In the upper forest line areas, deforestation for pasture purposes is prohibited.
• Deforestation of overgrown pastures is allowed for the purpose of preserving the necessary pasture areas.
• In cooperation with agricultural professionals, the standards for deforestation of overgrown areas for agricultural purposes must be set. A detailed plan must be prepared for the deforestation areas. In agricultural areas, the ecologically indispensable parts of forests and individual trees must be preserved and the fragmentation of forest remnants must be prevented.
How was the indicator measured?
The data on deforestation were gathered from the annual reports of the Slovenia Forest Service (since 1999).
The method of determining the surface areas of deforestation is determined by the Regulation on the forest management and silviculture plans. The inventory of deforestation is made each year based on the evaluations and the planned scope of deforestation (from planning and project documentation). Fellings due to deforestation are documented according to the following causes: roads, other infrastructural facilities (power lines, gas pipelines, etc.), urban planning, agriculture, other.
