Inventory plan of silvopastoral systems in Greece

Silvopastoral systems cover relatively large areas in Greece and constitute an important vegetation type with great economic and environmental interest. They are mixed systems composed of forest trees with a crown density of no more than 40% and understory vegetation consisted of herbaceous and woody species (shrubs). The overstory species are used for the production of fruits and foliage to be fed to livestock while the understory vegetation is directly used by sheep, goats and cattle with grazing, making silvopastoral systems invaluable areas for livestock production. On the other hand, silvopastoral systems play a significant environmental role because they protect the soil from erosion, ensure an increased biodiversity, regulate the carbon sequestration, and control mountain hydrology. Conservation of silvopastoral systems is necessary for maintaining of good soil condition, increased biodiversity, improved rural landscape, and rural life in mountain areas. Also, the development of new systems that properly combine forest and animal husbandry products is imperative. The first step to this direction is to inventory the existing silvopastoral systems. This inventory will help to learn about their total area and their geographical distribution. It will also help to apply proper management practices and plan national policies for their sustainable use.
