Pirnat urban forestry in slovenia

  1. 1. Urban Forestry in Slovenia dr. Janez Pirnat, Biotechnical Faculty. Department of Forestry and Renewable Forest Resources janez.pirnat@bf.uni-lj.si Key words: Social and environmental functions, ownership & PR, financial pressures and spatial planning
  2. 2. Urban forestry – basic scientific sourcesMiller COST E12 COST E39 UFUG(1988) (2005) (2010) (2002 )
  3. 3. Urban forests (Slovenian COST E12 definition) Urban forests represent forests, parks, i.e woodland resources in urban areas that are due to their environmental and social, rather than production functions and benefits which they have for the citizens regarded, proposed and in one period of time declared as a forests with special purpose. »Urban area« is the area of town municipality (with possible corrections). The owner of urban forests should be in principle the municipality. Urban forests are situated within town area and are therefore daily accessible by means of public city transport (or cycling, walking) to at least part of habitants. Special management plan for these forest exists or shall be proposed in near future. The production role of the urban forests, declared as the forests with special purpose, diminishes and their social and environmental roles increases.
  4. 4. Urban forestry vs. Arboriculture Urban forestry in Slovenia adopts the principles of multi-purpose management (according to Slovenia Forest Law) and applies them to planning, establishment and management of the urban forests, trees in parks, along avenues and solitary trees in urban area. Arboriculture is a science of individual tree care in an urban environment.
  5. 5. Slovenia – a forested countryMost of Slovenian towns are surrounded by forestswithin 1km walking distance (Pirnat and Hladnik, 2009)
  6. 6. Ljubljana MariborCelje Kranj
  7. 7. Ordinance on Special Purpose Forests inLjubljana (Ur. L. RS, 60/2010) This ordinance defines forests, which are due to extremely emphasized social forest functions declared as special purpose forests Adopted management plan Contractor‘s responsibilities Responsibility of Municipality to provide funds for costs resulting from special management regime, investment in equipment and also compensations and the purchase of forests on request.
  8. 8. Special Purpose Forests in LjubljanaMunicipality as declared by Ordinance (2010)
  9. 9. Combining historic and modern analysis inurban forestry (Hladnik and Pirnat, 2011) Evaluation of spatial forests distribution according to their close to naturalness, based on their tree structure and forest continuum in space (black)
  10. 10. SWOT analysis on Urban forestry in Slovenija as seen after COST E12.Strengths: public forestry service, with a long tradition in multifunctional management legislation that allows the forest with special purpose awareness of the importance of urban forests and the need for cooperation with forestry in the city administration is increasingWeaknesses: lack of regulations adopted to protect the urban trees and forests lack of tradition and expertise in arboriculture no register (or no interest to make) street tree cadastre unfavorable ownership structure of the urban forestOpportunities: development of urban forest functions and roles („ecosystem services“) public participation in caring for city trees transfer of scientific knowledge to practical workThreats: incorrect tree care lack of financial sources

  12. 12. SWOT – students of Urban Forestry 2012 - I Strengths Weaknesses General knowledge  Lack of knowledge of Practical field work Landscape architecture Positive attitude to trees  Lack of sociological and Good knowledge on trees humanistic knowledge  Weak information of legislation Way of thinking that ecosystem dimension,  Emotional rather than rational sustainability as decision impules indispensable paradigm  Lack of knowledge on herbaceous perennial plants  Weak in communication with stakeholders
  13. 13. SWOT – students of Urban Forestry 2012 - II Opportunities Threats Increasing awarenes of  Competition from other importance of recreation disciplines (Landscape arch...) Enough of green areas  Stereotype on foresters Knowledge and skills to  Stereotype on forestry make and maintain tree (consistent work) cadastre  Recession Knowledge on arboriculture  Effects are noticable in New discipline – new long-term opportunities in Slovenia  Climate changes Knowledge of languages –  Invasive species opportunities abroad
  14. 14. Future work for urban forestry in Slovenia Define urban forests and follow the procedure to declare them as Special Purpose Forests, managed in one independent management unit. Appropriate emphasis should be given to small biotops of natural vegetation as “stepping stones“ or „indispensible pattern of nature“ in an urban environment. Development of a modern remote sensing approach to analyse urban forest structure, individual tress and recreation pressure types. Inventory of urban trees and roadside tree cadastre on public land and development of strategies for the management, which covers the maintenance, restoration, timely information and publicity.
