“…Tree stands of such secondary woods were probably composed of even-aged Alnus with Betula pendula and Betula pubescens in admixtures. In the understorey, Sambucus nigra and Salix were growing among other plants as is observed today (Bijak et al 2013). Additionally, alder expansion from the 1970s was enabled by the poor efficiency of local drainage causing the rise of ground water levels.…”

“…The spontaneous natural reforestation has become more and more important as the area of abandoned lands has increased in response to socio-economic changes that took place not only in the studied region but in whole of Central and Eastern Europe at the end of the last century (Bijak et al 2013;Młynkowiak and Kutyna 2009;Stanturf 2015;Zasada et al 2014). Low-intensity afforestation relying upon natural recolonization of abandoned fields and pastures has proven to be effective under the growing conditions of the whole Baltic region.…”

Pollen, charcoal and geochemical investigations were carried out on annually laminated sediments of Lake _ Zabińskie (54°07 0 54.5 00 N; 21°59 0 01.1 00 E) and the results were combined with historical and climate data to better understand the mechanism behind plant cover transformations. A millennium-long record of environmental history at 6-years time resolution permitted an assessment of vegetation responses to past human impact and climate fluctuations. Our results show that the history of the region with repeated periods of warfare, epidemics, famine and crop failures is well reflected by environmental proxies. Before the Teutonic Order crusade (AD 1230-1283), agricultural activities of the Prussian tribes were conducted at a distance from the studied lake and caused slight disturbances of local forests. A stronger human impact was registered after ca AD 1460. We confirm that co-domination of pine forests with spruce and oakhornbeam forests on drier habitats as well as the presence of birch and alder woods on wet surfaces near the lake lasted until AD 1610. We identified a transition period of 20 years between AD 1590 and 1610, when forest cover was significantly reduced and the area was partly transformed into open land used for farming activities. The comparison of our data with other pollen datasets from the region confirms significant spatio-temporal differences in the initiation of large-scale woodland clearings in the Great Masurian Lake District. A strong increase in local cultivation was noted after AD 1750 and became even stronger in the period AD 1810-1940. The last 60 years experienced a succession from arable fields and open grasslands to more tree-covered habitats overgrown by birch and alder.

“…We did not separate fine and coarse roots in this procedure. Because previous studies demonstrated that coarse roots, which have longer residence time than fine roots, made the predominant contribution to root biomass (IPCC 2006;Miller et al 2006;Bijak et al 2013;Smyth et al 2013), we assumed that disregarding fine and coarse roots is acceptable in terms of quantifying the total root biomass.…”

The aggressive expansion of Moso bamboo (Phyllostachys pubescens) forest into adjacent ecosystems which might alter the carbon balance replacement, has been noted recently in East Asian countries such as Taiwan. Moso bamboo has a biennial growth cycle that causes significant inter‐annual variations in net primary productivity (NPP) and net ecosystem productivity (NEP). To our knowledge, only one study has investigated NPP covering biennial cycles in a Moso bamboo forest. Therefore, the aim of the present study was to clarify the NPP and NEP in a Moso bamboo forest in Taiwan by considering above‐ and below‐ground processes over a 4‐year experimental period. The estimated NPP and NEP showed considerable inter‐annual variations (coefficient of variation of 39 and 79%, respectively). Averaged over the 4 years, the NPP and NEP were 8.86 ± 3.46 and 4.32 ± 3.35 Mg C ha−1 year−1, respectively, which were within the ranges (6.53–14.36 and 3.59–7.98 Mg C ha−1 year−1, respectively) reported for Moso bamboo forests in East Asian countries. A global comparison of NPP and NEP among forest ecosystems using data from published literature indicated that the estimated NPP and NEP in the present study, as well as those in Moso bamboo forests from East Asian countries, were within the upper range of the values reported for other forest ecosystem. The results indicate that Moso bamboo forests may have high potential as a carbon sink among forests ecosystems.

Jagodziński and Kałucka (2011) and Bijak et al (2013) were estimating the belowground biomass of birch and pine in stands resulting from afforestation on agricultural lands.

Abstract. The United Nations Framework Convention on Climate Change and the Kyoto Protocol have committed member states to reduce greenhouse gas emissions by, among others, promoting the increase of carbon sequestration by carbon sinks (including woody biomass in forests). In order to achieve these objectives, an international reporting system was designed.The stock of woody biomass depends on several environmental and managerial factors, which determine species composition and age structure of a forest as well as characteristics of individual trees. Estimating aboveground woody biomass, especially on a nation-wide level, is generally based on the application of conversion factors to known characteristics such as the volume of the growing stock. The application of default conversion factors, as proposed by international guidelines, however, is questionable, since inventory systems for and definitions of growing stock differ from country to country.In this paper, the methods used in Poland to estimate woody biomass for the FAO and the UNFCC reporting, were presented and analysed. We also analysed the influence of some stand and tree characteristics, such as tree species composition and content of bark and its density, on the stock of woody biomass. We conclude that issues not addressed in the IPCC guidelines, such as big differences in wood and bark density, especially for pine, need to be taken into consideration when making estimations. Moreover, the results of this paper show that biomass conversion and expansion factors (BCEF) proposed by IPCC are not adequate for Polish conditions.
