Forest certification as a voluntary verification tool has been providing an independent assessment of sustainable forestry practices and thus confidence in sustainability benchmarks for over 20 years. Using either the international or national approaches and initiatives, two main forest certification systems, PEFC (Programme for the Endorsement of Forest Certification) and FSC (Forest Stewardship Council), have spread in a number of countries worldwide. The specifics of local conditions in the forestry sector have to be taken into account when implementing the certification context in a given country or a region. Apart from the natural conditions, institutional structure, or legislative framework, it is also the local and national stakeholders and their perception of this issue that provides the background for the implementation of the certification criteria. The main objective of this study is to examine the general understanding of the certification concept as an environmental, economic, and social tool, and to determine the incentives of forest owners in Slovakia for sustainable forest management (SFM) certification. In addition, the benefits and problems arising from participation in certification were identified and differences reflecting the ownership structure of forests, size of forest area, and participation in a particular certification programme were analysed. Results indicate that certified forest owners, unlike non-certified, demonstrated a high level of understanding of the SFM certification concept. Certified entities mainly consider forest certification as their commitment to environmental responsibility and a tool for improving external company image, promoting sustainable utilisation of forest resources, and improving forest management practices. The main benefits are linked to the possibility to demonstrate forest management practices, a better understanding of the forest management concept, and improvement of forest management practices. PEFC users perceive more benefits following from certification; the most important are those associated with non-economic values, while FSC-certified forest owners perceive mainly economic benefits connected to market penetration, increased sales volume, and potential price premiums. The key problems associated with certification relate to duties to ensure compliance with certification criteria by contractors and administrative difficulties. Respondents reported minimum price premiums for the sale of their certified timber. Additionally, the findings of the study pointed out that a nationally developed certification system can better recognise the roles and objectives of forest certification in the context of forest policy.

The red heartwood of beech is responsible for decreasing the market value of the most important deciduous tree species of central Europe. The aims of this study were: (i) to verify the hypothesis that stand age affects the occurrence and metamorphosis of red heartwood in beech; and (ii) to quantify the economic loss due the sale price reduction of timber affected by red heartwood. Seven even-aged beech stands of different age (87, 100, 105, 110, 115, 132, and 145 years) were selected in Slovakia, and 213 trees were cut into 961 pieces of assortments which were evaluated for the presence, form and extension of red heartwood. The economic loss caused by red heartwood was determined as the difference in price between the actual and the potential quality grades of assortments. The results confirmed that stand age significantly influence the occurrence, development, and metamorphosis of red heartwood. The average loss in timber sale price caused by red heartwood varied between 0.76 and 28.04 € m-3, depending on age and form of red heartwood, with more severe losses in stands older than 110 years. To reduce the incidence of beech red heartwood in Central Europe, a reduction of the rotation period should be considered, as well as the adoption of suitable silvicultural practices in aged beech stands.

The aim of the paper is to present an overview of the forestry services market in Slovakia in terms of forestry services customers and to identify key factors determining existence and functioning of the market in the sphere of logging transport process. Methodically the paper is based on case studies elaborated on the basis of standardised interview carried out with selected forest owners and managers. As shown by the results, crucial factors influencing decision making about forestry services are machinery and technological equipment of forest enterprises, availability of financial resources, amount of performed work, production and transaction costs and legal constrains resulting from the Act on Public Procurement. The results of the questioning and case studies allowed defining basic economic assumptions of the forestry services market functioning under the current conditions in Slovak forestry.
