Successional Stages

Lomatia hirsuta (Lam.) Diels is a pioneer tree species that develops after wildfires, and in advanced successional stages, it is often found as a secondary species in Patagonian forests. However, in El Manso Valley, Province of Río Negro in Western Argentina, L. hirsuta forms mature pure stands, originated from stump shoots. The wood is very attractive for its colourful appearance and beautiful grain. Nevertheless, these forests are not managed for timber production, they are mostly strong thinned for grazing, and the wood is mainly used as firewood. The objective of this study was to evaluate the possibility to improve quality wood production in stands through silvicultural interventions in a sustainable way. Samples have been carried out in stands of different developmental stages. We evaluated the state and quality of the trees, and their growth has been studied by means of trunk analysis. The results indicate that there is significant potential to improve the production of quality wood in dense stands by thinning to release crop trees. Thinning should start in young stands. It also became apparent that forest management is first necessary to stabilise these nearly unattended forests.

Lomatia hirsuta (Lam.) Diels is a pioneer tree species that regenerates mostly after fire and is more frequently found as a secondary species in Patagonian forests dominated by Austrocedrus chilensis and Nothofagus dombeyi. However, in the El Manso Valley, Province of Río Negro in Western Argentina, L. hirsuta forms pure stands, originated from stump shoots. The wood is very attractive for its colourful appearance and beautiful grain, suitable for fine furniture. Nevertheless, these forests are not managed for timber production, they are mostly thinned for grazing, and the wood is mainly used as firewood. The objective of this study was to evaluate the possibility to improve quality wood production in stands through silvicultural interventions in a sustainable way. Samples have been carried out in dense stands of different ages and in one less dense stand with the traditional use for pastures. We evaluated the state and quality of the trees, and their growth has been studied by means of trunk analysis. The results indicate that there is a significant potential to improve the production of quality wood in dense stands through thinning oriented to crop trees. This should start in young stands, because in older stands, good form and sound trees are already considerably reduced. It also became apparent that forest management is necessary to stabilize these nearly unattended forests, which in old stands are very vulnerable to damages caused by wind and wet snow. In such stands, the extraction of trees could be combined with the planting of seed trees, with the expectation to improve the quality and vigour of the trees at maturity.

Forested Area

White poplar is a native stand-forming tree species in Hungary, covering 3.1 per cent of the forested area. More than 70 per cent of the white poplar stands can be found on calcareous sandy sites in the Danube—Tisza region, so they play a significant role in the poplar management of this part of the country. The most important task ahead of Hungarian poplar growers is to improve the quality of poplar stands and plantations based on selecting new clones and cultivars. The growth and yield of four promising white poplar clones was evaluated on a marginal site in central Hungary. The clones `1-1 425-4' (Populus alba x Populus alba), and 11 758' (Populus alba Mosonmagyaróvár 124) seem to be suitable for wood production, while the 427-3' (Populus alba x Populus alba cv. Bolleana) and 422-9' (Populus alba x Populus grandidentata) clones (with decorative stem form) could be better used for tree lines and ornamental plantations.

The Relationship

The present study examines the relationships between the indicators of tree species and structural diversity and the quality of timber production in young even-aged forest stands with the average age below 40 years. The study is based on the forest inventory data from University Forest Enterprise Kostelec nad Černými lesy, Czech Republic, performed from 2009 to 2011. The examined young stands were recorded in 256 sample plots representing 21.2% of the enterprise area. On each sample plot, we quantified 171 partial biodiversity indicators. In total, we analysed 16,416 different variants of the relationship between the diversity indicator and the quality of timber production. The analysis revealed that similarity indicators such as the range of tree heights, Canberra distance, Bray and Curtis index, and index of species evenness and heterogeneity were the most frequent basic indicators occurring in significant correlations. The results indicate a positive relationship between the proportions of assortments in quality classes I to IV and stand diversity expressed by the number of tree species and Canberra distance.

Certification Programme

The article describes about cerlification programme for sustainable forest management. Concern for forest problems has increased dramatically over last decade. Sustainable forest management is an inherent aim of certification. It is the ultimate goal to which certified forest should aspire, but such a goal is reached only through a period of transition, during which management standards are progressively established and fine-tuned. The explicit aim of certification is to improve the quality of forest management so as to reach this goal. The aim of certification systems is to make timber production more ecologically and socially responsible and economically viable by grading sources so that consumers can choose on these grounds. The argument is that environmentally aware consumers will be prepared to pay more for products if they know where these come from and how they have been produced. Higher prices will motivate timber companies to implement sustainable forest management principles. There are certain general principles of sustainability which have been agreed, these include emvironmental sustainability social sustainability and economic sustainability. This article describes focus on certification in context, certification in practice, views on certification, overall trends in the certification debate, the sticky issues differing views that need resolving, and the forest certification programme in lndonesia.

The article describes experience of creating and implementing information-managing educational environment at university. The model of creating information-managing educational environment of university with elements of artificial intelligence and indicative management is described. This environment contributes to improve quality of training and management of educational processes and resources. The stages of creating and implementing information-managing educational environment are considered systemically, as continuous process focused on a consumer. The inhibitory and facilitating conditions for introduction of the model at university are described. To provide subject-oriented approach to the use of information resources of environment, recommended clusters of information subsystems for each category of users are described.Practically implemented scientific and methodological recommendations for subjects of educational process to overcome resistance to innovations introduced in educational organizations are proposed.Features of adaptation of the developed information-managing educational environment for schools are presented.
