    Opis:
    Greenhouse gas control it is key aspect for climate protection. The positioning of corporations concerning greenhouse gas emissions (GHG) has changed profoundly in the past two decades. As climate regulation became inevitable, companies started adopting more proactive strategies. One of the effective methods for greenhouse gas emission calculation is based on life cycle analysis. A carbon footprint is defined as the sum of greenhouse gas (GHG) emissions caused by an organization, event, or product and is expressed in terms of CO2 equivalents (CO2-e). Our investigations were devoted to greenhouse emission assessment during life cycle of willow wood production from short rotation coppice plantations. In accordance with results about 48% of carbon dioxide gas from all life cycle of willow was emitted during wood harvesting and transportation to energy plants. It is necessary to optimize the logistic scheme of willow wood harvesting and transportation for decreasing of greenhouse gas emission. The substitutions of fossil fuel by willow wood enable to save 11733 ton CO2-e from 30 hectares of willow plantation. The carbon tax for instance in Australia starting at AU$ 23 a ton of Carbon Dioxide equivalent (tCO2e). Thus, the substitute of fossil fuel by willow wood may have profit as for regional so and for local level of production.

    Opis:
    The use of biomass for energy purposes is an important European Union policy. In light of the restrictions concerning the use of the full−value wood from forests for energy purposes, short rotation forestry can become an alternative source of woody biomass. In this context, the most promising species is poplar (Populus spp.), productivity of which depends on various aspects such as plant spacing, cutting cycles, fertilization and cultivar characteristics. The aim of this study was to assess the possibility of cultivation of ten selected poplar clones from the section Aigeiros and Tacamahaca in short−rotation coppice in the climatic conditions of Poland. An experiment was set up in the north−eastern part of Poland in the Wichrowo Forest District. Survival, tree stocking, and biomass yield were compared. Productivity of clones was examined in five−year cutting cycle. The highest dry biomass yield (7.8 t/ha/yr) was achieved by the clone 'Hybrida 275'. In contrary, the biomass yield of the worst clone ('AF−8') amounted to 2 t/ha/yr. Some other Italian clones, such as 'AF−6' and 'MON' were not able to adapt to the local conditions at all and were excluded from the experiment. Because of the need to implement the full economic analysis of short rotation poplar plantations, it would be important to study propagation ability of certain currently studied varieties of poplar in subsequent rotations and with different production cycle period length up to the end of biomass production on a given plantation. Resistance to diseases of energy poplar plantations should also be researched.

    Opis:
    The study assessed the effect of composted municipal sewage sludge on the wood yield of an experimental willow short rotation coppice (SRC) during the second harvest cycle. The mean values of BOD7, total N and total P met the legislative limits set to prevent groundwater pollution at the soil depth of 40 cm. We demonstrated that more productive plants of the first harvest cycle could lose that trait during the next. The second harvest cycle was more productive in terms of wood yield than the first for plants of both treatments. Sludge treated willows had significantly higher wood yield.

    Opis:
    Coppice belongs to the oldest forestry models in Europe and is still cultivated in some regions. Despite the smaller productivity compared to high forests, coppice forests are important for protection of natural values, cultural heritage, production of small−sized timber, mitigation of climate changes, provision of non−wood products as well as providing a protective and recreational function. The most important forms of coppice management are simple coppice and coppice with standards. The varieties of the previous include short rotation coppice and selection coppice. In addition, there are two other management systems, that use vegetative regrowth of individual trees – pollarding and shredding. In 2000, the area of European forests and plantations regenerated in a vegetative way by stump shoots, stool shoots and suckers, amounted to about 23 million hectares (16% of the area of production forests). These forests consist of primarily native European trees species, but in some regions there are plantations of alien species, generally grown in short production cycles: eucalyptus, black locust and American poplar varieties. The paper analyzed the area of coppice forests in selected European countries. Our continent can be divided into three zones in terms of the use of coppice management system: Central Europe, Great Britain and Ireland (I), Mediterranean countries (II) and the Baltic countries, located north of Poland (III). The area of coppice forests in the majority of countries in zone I is small due to the process of their conversion to high forests, that has been progressing since the second half of the twentieth century. Coppice forests are of particular importance in the Mediterranean countries, where they are still a reservoir of biodiversity and an important source of wood and non−wood products. In zone III, due to the superiority of coniferous species in forests, there is no tradition of coppice management. On the other hand, there is growing interest in short rotation coppice for the production of biomass. Such attitude, currently observed in many European countries, is not only because of climate protection, but also of cultural tradition and biodiversity. That is why in some countries, the return to this traditional form of forest management is supported by the state. Coppice forests can be, especially for small private owners, a rational model of forest management.
