Socioeconomic and Arboricultural Evaluation of Park–Forest Jelenovac in Zagreb

Urban forest represents a forest covered area nearby an urban area. Urban forests in City of Zagreb are situated on 22 separate locations and cover 395, 08 ha, distributed mostly over northern parts of the city at the lowest south, southwest and south east slopes of Medvednica mountain. They are surrounded with urban settlements and family houses, making them under pressure to decrease the area which considerably influences their functioning. Also, they are an integral part of Zagreb’s green areas and represent attractive places for both citizens and visitors. The goals of the General urban plan in Zagreb (GUP) are protection of historic and natural values and continuous registration and restoration of endangered historical and other city identities like morphological diversity and park forests. City park forests could be modified into park areas, with management that preserves their natural forest structure and with equipment in favour of recreational facilities as one of the non-wood forest functions. The plan for the park-forest area management is defined within city bodies’ responsible for forest management and protection of specific nature protected areas in city area. Basic characteristics of arbour species and estimated visual characteristics of Park Forest Jelenovac were determined using the field measurements. Sample consist 610 selected trees of different species (quercus robur, ash, common beech) distributed over the research area. Using the cost benefit analysis method, tending and rehabilitation costs needed for the stand management have been used and estimation has been made of ecological and social benefits from the stand production. Analysis was conducted in accordance with the group of trees defined within same species. Urban forests costs consist of tree plants costs, human work, maintenance costs etc. Benefits are non-wood forest functions, especially recreational, health, touristic and aesthetic components. Results show positive correlation between costs and benefits offered by urban forest and analysed tree sample. Conclusion confirms that investment in urban forests management besides socioecological has also the economic justification.
