Biomass of Scots pine-silver birch tree stand 25 years after afforestation of former agricultural land

Abstract

Scots pine (Pinus sylvestris L.), silver birch (Betula pendula Roth) and several seedlings of the European beech-after many years of agricultural cultivation of grain and potato crops. Characteristics of the forest stand comprised the following parameters: species composition and species diversity, density of individual components, the average tree diameter at breast height (DBH), and the height and aboveground biomass of trees divided into individual species. The species structure, dendrometric characteristics and spatial distribution of trees studied in 2015 were compared with the situation assessed in 2000. Based on DBH and height values, as well as the use of dendrometric tables and basic wood density for tree species, the aboveground biomass and total biomass of trees with a minimum diameter of 7 cm were calculated. The aboveground and total biomass for trees with DBH less than 7 cm was calculated on the basis of density and weight of trees according to the classification into species and height classes. The aboveground and total biomass of the whole tree stand, including spontaneous non-native and invasive Padus serotina pine-silver birch plantations on former agricultural lands described in ecological literature. The paper presents also the differences in assessments of aboveground pine biomass at the study site obtained when using converapplied during inventories conducted in Poland according to the IPCC recommendations for international reporting submitted to the

Regional to Global Biogenic Isoprene Emission Responses to Changes in Vegetation From 2000 to 2015

“…However, it should be noted that the broad‐leaved tree silver birch ( Betula pendula Roth ) and the needle‐leaved tree Scot pine ( Pinus sylvestris L . ), which are regarded as low isoprene emitters, were the dominant species for European afforestation (Deptula et al, ); hence, the actual increment of isoprene emission should be much lower than the value derived from the work of Lathière et al (). A net increase of about 4% in Germany and France was contributed by both broad‐leaved and needle‐leaved trees.…”

“…Lathière et al (2006) concluded that European isoprene emission was significantly affected by European afforestation with an isoprene emission increase of 126% from 1983 to 1995, since crops were substituted with temperate broadleaf evergreen trees resulting in the enhancement of isoprene emission capacity by a factor of 9. However, it should be noted that the broadleaved tree silver birch (Betula pendula Roth) and the needle-leaved tree Scot pine (Pinus sylvestris L.), which are regarded as low isoprene emitters, were the dominant species for European afforestation (Deptula et al, 2017); hence, the actual increment of isoprene emission should be much lower than the value derived from the work of Lathière et al (2006). A net increase of about 4% in Germany and France was contributed by both broad-leaved and needle-leaved trees.…”

Macro- and Micronutrient Contents in Soils of a Chronosequence of Naturally Regenerated Birch Stands on Abandoned Agricultural Lands in Central Poland

“…The afforestation of former agricultural land is a process that has received considerable socioeconomic attention in recent years [1][2][3][4][5][6][7][8]. Since the energy from renewable resources has been widely promoted, the production of large quantities of easily accessible and useable highly energetic biomass from trees has gained attention, leading to the publication of numerous research papers on the ecological processes for modelling such ecosystems (e.g., [9][10][11][12][13][14][15][16][17][18][19][20]).…”

Planting a Linear Vegetation Element in Landscape Using a Forestry and Landscaping Method—Can We Tell Which Deliver Greater Success?

“…A study of the Czech and foreign literature has revealed that there are basically no studies in which the results could be compared with. Focus on other plantings with different parameters of height and trunk diameter, e.g., Jelínek, Úradníček [37] and Deptula et al [22];  Focus on the relation between mortality or vitality to another specific factor (specific nutrients in the soil, mode of seedling production in a nursery, shading, etc. ), e.g., Dostálek et al [29] and Tužimský et al [44];  Do not cover shrubs, as presented in Jelínek [34].…”

“…This method is often applied for afforestation of farmland with the aim to establish economically managed forest stands. This topic is covered by a number of research papers, e.g., by Nizinski [16], Friedrichsdorf [17], Bartoš and Kacálek [18], Jylhä and Hytönen [19], Leugner [20], Vacek et al [21] and Deptula et al [22]. Forestry method of establishing woody stands is also used in the reclamation of land after mining and mineral extraction.…”
