    Agroforestry is a collective name for land-use systems and technologies where woody perennials are deliberately used on the same land-management units as agricultural crops and/or animals. Silvopasture is a type of agroforestry that integrates trees, livestock, and forage crops on the same piece of land. This topic is specifically interesting because silvopasture is already present in Finland, mostly in the form of traditional biotopes, despite these being endangered habitats. Agroforestry is also recognized by the Kyoto Protocol as an afforestation practice that has several advantages. These include environmental benefits, increased productivity, and animal welfare. However, there has been discussion on detrimental effects of animal presence to the trees as well. This research aims to explore the effects of silvopasture on trees, cattle, and the environment in South-western Finland traditional biotopes. Several individual criteria are assessed in three categories: woodland, animal performance and biodiversity. Data was collected on three farms on four pastures through field surveys and farmer interviews. The data is analyzed through multi criterium decision analysis (MCDA) with normalized values from agriculture and forestry to assess performance of silvopastures on three separate categories. Results from four pastures follow a somewhat similar pattern but variation occurs. High scores of forest indicators are reached in woodland category whereas biodiversity category results are lower. Silvopasture negatively affects forest regeneration but otherwise does not have adverse effects. Cattle performance is positive outcome whereas biodiversity category has room for improvement. To get more accurate and comprehensive results the research should be conducted during growing season and with several farms around Finland. However, silvopasture is a meaningful measure to diversify habitats, contribute to animal wellbeing and strengthen ecosystem services.
