  • Air pollution monitoring with hybrid and optical sensors in Curitiba and
           Araucária, Brazil

    • Abstract: Complex mixtures of substances are in the atmosphere and they can cause diseases in humans and biological communities after acute or chronic exposition. This paper focuses on the physical measurement of particulate matter, a proxy for air pollution, and a biological method for mutation assessment due to plants’ exposure to air pollution. The objective of this research was to characterize the air pollution seasonality in municipalities in southern Brazil, and also to understand the relation between air pollution and the biological response of the Tradescantia sp. clone 4430. The optical sensor SDS011 was used for measurements of particulate matter (PM) and the Trad-SHM bioassay was chosen to quantify the mutagenic alterations that occurred in stamen hairs during the study period, with PM data being measured every 5 seconds and the flowers being harvested approximately every two weeks for laboratory analysis. The Pearson test was applied to verify the correlation between PM and mutations in stamen hair as a result of which it was observed that there is a positive correlation between these data, with the highest value found being r = 0.61. Also, the period with the highest occurrence of pink cells was between autumn and spring, the same period in which an unusual increase in PM concentrations was also observed, a period that corresponds to a less favorable dispersion of pollutants in the atmosphere. The use of Tradescantia sp. clone 4430 showed sensitivity to the environments in which it was exposed. Biomonitoring is an important tool for understanding the effects of pollutants on the ecosystem.

  • Water and carbon balances in a hemi-boreal forest

    • Abstract: The carbon and water fluxes and their inter-relations are key aspects of ecosystem dynamics. In this study, regionalization was used in transferring parameters from the GR4J-Cemaneige model calibrated in Reola hydrographic basin to predict daily flows in Kalli basin; both watersheds are located in the southeast of Estonia. Evapotranspiration data was collected from the MODIS sensor of the Terra satellite and from the Station for Measuring Ecosystem-Atmosphere Relations (SMEAR Estonia). Precipitation data was collected from Tartu–Tõravere and SMEAR Estonia stations and river flow from Reola hydrometric station. The year 2011 was used for model warm-up, model calibration was done in 2012–2017 and the 2018–2020 period was used for validation. The GR4J-Cemaneige model was calibrated at Reola Basin, with a Nash-Sutcliffe Efficiency index of 0.73. The 6 constants of Reola subbasin were transferred to Kalli subbasin for river flow simulation. Net ecosystem exchange (NEE) was measured at the 70 m SMEAR tower with the eddy covariance technique. The balances indicate that the ecosystem at Kalli watershed is slowly becoming a source of carbon and less water is available at the catchment reservoir. NEE has increased from -1.23 μmol m-2 s-1 in 2015 to -0.62 μmol m-2 s-1 in 2020, while the delta water storage decreased from 0.24 mm in 2015 to -0.05 mm in 2020. This behavior may increase soil drying and oxidation, and it will probably release more carbon in the future. This research allows a better understanding of the Järvselja hemi-boreal forest water-carbon dynamics.

  • The model of stand basal area gross growth on the data of the Estonian
           Network of Forest Research Plots

    • Abstract: The stand level gross volume increment models are used to estimate the future production of tree stands. Very often, the stand growth and yield in the models used in practice are described by the tree volume increment that includes the diameter growth function with the tree height together with stem taper as the input variables. The currently used function of stand volume increment in Estonia included also stand relative density as an additional input variable. In the current study, we developed a basal area increment function based on the periodic measurement data of the Estonian Network of Forest Research Plots (ENFRP). As in the earlier model of stand volume increment developed by Priit Kohava, in the current model the basal area increment of tree species is developed for a pure stand, and for mixed stands, the proportion of the tree species’ basal area is used. The tests in our data indicated that the periodic increment prognosis had good fit in the case of variable share of tree species in the main storey and coincide with the earlier studies by Finnish and Swedish colleagues. The developed model of basal area increment predictions are expectedly higher than the earlier model predictions for the most tree species and stand relative densities.

  • Acorn production of pedunculate oak in northeast of Ukraine

    • Abstract: We analysed the quantity and quality of Quercus robur L. acorns after years with a very poor yield under the canopy of natural oak stands of various compositions, ages and stock densities in the northeastern part of Ukraine. We determined the mass of 1,000 healthy and damaged acorns of the current year. The levels of variability were estimated for the number and mass of acorns under the canopy of the studied stands. The dependences of the number of acorns on the age of oak stands and their stock density were studied. The total number of acorns under the canopy of natural oak stands was 9,900–19,000 seeds per hectare with a total mass of 26.8–54.1 kg per hectare in 2020 and 8,600–17,200 seeds per hectare with a total mass of 22.7–48.4 kg per hectare in 2021. The proportion of damaged acorns was about 70% both in 2020 and 2021. The largest number of acorns was concentrated under healthy trees (without signs of decline) that had a well-developed crown and, therefore, received more sunlight and heat. The identified quantitative and qualitative estimates and acorn spreading pattern need to be considered when selecting sites for further natural seed regeneration in old-aged oak stands.

  • Assessment of the soil-protecting services of the forest ecosystem: a case
           study in Ilam catchment, Iran

    • Abstract: The natural forests of western Iran play a key role in delivering services and goods to local society. Nonetheless, this forest ecosystem, despite its importance, is threatened by natural factors and anthropogenic activities, resulting in decreasing soil quality and soil erosion. The present research aimed to assess the effects of the forest ecosystems on soil erosion control in Ilam catchment in southwest Iran. For this purpose, after estimating the soil loss in natural conditions (NC), we predicted the amount of soil erosion under two scenarios: (i) convert natural forest with 20% canopy cover to destructed forest with 0% canopy cover (SC.1), (ii) increase forest cover by 40% (SC.2). Our results indicate that the estimated mean soil erosion was within the range of 9.36 t ha-1 yr-1 in irrigated and garden use to about 256 t ha-1 yr-1 in bare soils under NC. We found that when converting natural forest to destructed forest, the mean annual soil erosion rate increased 105.75 t ha-1 yr-1, 118.1 t ha-1 yr-1, and 19.57 t ha-1 yr-1 in the dense forest, sparse forest, and Agri-Forest use, respectively. These results show the protective effect of the forest against soil erosion.

  • Dynamics of chemical and microbial properties of Algerian forest soils:
           Influence of natural and anthropogenic factors (Northwest of Tlemcen)

    • Abstract: In Djebel Fellaoucene, mattorals and their regressive and progressive dynamics are affected by several factors, namely climate, geography, human activities, overgrazing and fires. This research aims to investigate whether these factors have an impact on the structural dynamics of the area’s forest soils and show a correlation between the soils’ chemical and microbial properties and these factors. In this regard, we have analysed chemical properties: organic matter, pH, conductivity, calcium carbonate (CaCO3), moisture and carbon as well as microbial properties: basal respiration, microbial biomass and metabolic quotient (qCO2), all from 80 soil samples collected from degraded mattorals on different altitudes and exposures. Principal Component Analysis (PCA) which has been made revealed that soil dynamics and correlations between chemical and microbial properties depend on the aforementioned factors; an increase in moisture, organic matter, carbon and conductivity as well as a decrease in the mass and bacterial respiration in the North-exposed sites under anthropogenic pressure and overgrazing by sheep and goats. Whereas opposite results were found in the South-exposed sites degraded by fires and undergrazing by cattle. Anthropogenic pressure and overgrazing in sites which have recently been burned lead to a decrease in microbial properties despite an increase in organic matter and moisture content. Qualifying and quantifying the impact of these degradation factors on forest soils allows us to establish effective restoration, conservation strategies and defend rangelands in arid areas.

  • Assessing the efficiency of the forestry sector in EU countries

    • Abstract: This paper deals with a quantitative assessment of the production efficiency of the forestry sector in EU countries, which is largely neglected in the literature. Only a few studies have been conducted so far, processing data mainly in the first half of the last decade. In contrast to these studies, in this article we focus on the period between 2016 and 2020. Therefore, the main objective of this paper is to compare the efficiency of the forest sector to fill the gap. The empirical results of this study show that the leaders in this sector are Germany, Finland, and the Czech Republic. These countries are fully efficient throughout the period under review. In contrast, Bulgaria lags far behind, with an efficiency score typically around 35%. The results of the cluster analysis show that although countries have similar characteristics, their efficiency scores are not necessarily at the same level.

  • Methodology for the assessment of damage and economic losses from harm to
           forest ecosystems as a result of armed aggression

    • Abstract: Significant changes in the environment have caused awareness of the strategic importance of forests as a factor in global environmental security, and socio-economic development of territories. Evidence of this are many international acts, including the provisions of the New EU Forest Strategy for 2030. However, in areas where hostilities are taking place, forests are being destroyed en masse, leading to systemic losses, the restoration of which will require large investments, efforts, and a long period of time. Therefore, it is important to improve the mechanisms for recovering compensation from the aggressor country, whose actions have led to losses from loss or damage to forest ecosystems. In this case, justification of the amount of compensation plays a significant role, and therefore there is a need to develop methodological approaches to their definition. Based on the summary of international practices, guidelines of international organizations, regulations of Ukraine, and scientific publications on the assessment and compensation of environmental damage, the author used a systematic approach that combines the assessment of damage from loss or damage to forest ecosystems and the cost of their restoration. The methodology involves taking into account the degree of damage in determining losses, lost profits, and costs of restoration of forest ecosystems in the context of forest ecosystem services – Provisioning Services, Regulating Services, Supporting Services, or other ecosystem maintenance services; Cultural Services, such as educational, aesthetic, and cultural heritage values, recreation, and tourism. The author proposes relevant methods for each component of the assessment and the relevant indicators. In determining the sets of indicators the author used those that can be calculated based on objective data, or that have an international practice of their calculation. The choice of data sources for the calculation of damage and losses from losses or damage to forest ecosystems and objects within them, caused to Ukraine as a result of hostilities, is stipulated.

  • Investigation and modelling of the electrical charging effect in birch
           wood above the fibre saturation point (FSP)

    • Abstract: Wood moisture content (MC) has a significant impact on all electrical properties of wood. Regarding the development of the (so-called polarization-type) wood moisture meter with the electrical charging effect for monitoring and controlling the wood drying process, it is of interest to expand the theoretical background of this type of novel wood moisture meter by means of modelling. Two mediums were selected for modelling – raw birch wood and, as a reference medium, birch liquid sap – into which two symmetrical carbon fibre measuring electrodes were inserted. In both mediums, direct current and alternating current were passed between electrodes at different electrode potentials. The electrical field and electrical response of the current-affected mediums were then measured and modelled in the time domain and frequency domain. The numerical results of modelling are comparable both in the time domain and frequency domain (i.e. if E = 1.8V, then Cs = 0.5 mF and C1,int = 0.7 mF). The concept of energetic chargeability (CHA(W)) of wood was defined and compared to conventional chargeability as defined by C. Schlumberger in 1913. Empirical dependencies of CHA(W) on electrode potential and primary energy W1 transmitted through the wood (sap) medium were found. In the frequency domain, frequency dependencies were found to distinguish between adsorption processes and mixed kinetics ranges in birch sap and in raw birch wood.

  • Erosion control properties of self-seeded forests that appeared in
           forestless areas of ravine-gully systems

    • Abstract: During land unsoldering in Ukraine, so-called “self-seeded forests” appeared on lands that had not been used for agriculture for a long time. The purpose of the research is to find out the erosion control properties of self-seeded forests. Twelve locations of natural regeneration of various types of woody plants on the ravine-gully system of Cherkasy region were chosen as research sites. Self-seeded woods have a structure of different ages from 8 to 25 years. Most of them are represented by mixed stands, which increase their biological stability. They are better adapted to the current climate change. The formation of uneven-aged stands of natural regeneration with high resistance and erosion control properties was noted. According to the qualitative indicator of productivity, the natural regeneration turned out to be different, which was primarily caused by forest sites conditions, in particular, the steepness, the position on the slope, and the thickness of the humus horizon of the soil. The hardness of the soil was determined in the range from 17.1 to 19.0 kg/cm2, which corresponds to an average loose state. The hardness of the soil in the control was 23.9 kg/cm2, which corresponds to its compacted state. The water permeability of the soil under the studied stands was 11.1–27.3 (control – 8.9) mm/min, which characterizes it from the best to chasm. The obtained soil water permeability data confirm the rapid transfer of surface runoff to subsoil, which prevents the development of erosion processes. Natural regeneration on the slopes of the ravine-gully system is determined to be successful, although it requires considerable time for the formation of full-fledged plantations.

  • The influence of Sentinel-1 SAR sub-swath on the recorded backscatter
           time-series over managed hemiboreal forests

    • Abstract: The view angle range of Sentinel-1 SAR in the Interferometric Wide swath (IW) measurement mode is 29.1° – 46.0°. The dependence of backscatter on the arbitrary local incidence angle is usually corrected using a linear regression model where the incidence angle is a predictor variable. We analysed the whole time series of Sentinel-1 SAR VV-polarised backscatter over the flat 15×15 km test site in Laeva, Estonia (26° 26′ 43″ E; 58° 31′ 56″ N). Time series containing measurements from three different orbits were constructed for 3,159 stands from nighttime data and for 1,105 stands from daytime data. We can confirm that daytime backscatter is systematically greater than nighttime backscatter. We found a significant deviation from linearity in the backscatter dependence on local incidence angle. The empirical finding may be caused by the microwave scattering dependence on local incidence angle or by the influence of Sentinel-1 SAR sub-swath configuration in the Terrain Observation with Progressive Scans SAR (TOPSAR) method that is used for the measurements.

  • Puude hooajalise radiaalkasvu mõõtmiskuupäevaks moodustunud osa
           arvutusmudel Eesti tingimuste jaoks

    • Abstract: SummaryKnowledge of the seasonal dynamics of tree growth and its relationship with environmental factors is necessary to eliminate climate change’s current uncertainty and to model growth accurately. Despite the increasing number of studies on the seasonal growth of trees, such knowledge is lacking in a significant part of Europe, including the Estonian hemiboreal forest. To accurately determine the time between two measurement occasions in the Estonian Network of Forest Research Plots data analysis, it is necessary to consider how much intra-annual growth has been formed at the moment of the re-measurement occasion, because measurement dates usually do not coincide. In this article, we present a model that enables predicting tree seasonal cumulative relative growth at any date for environmental conditions in Estonia.Since seasonal tree growth observations in Estonia are still ongoing, the relative radial growth model developed in this study relies on data of neighbouring countries. We used growth data for Scots pine, Norway spruce and silver birch published by Vitas (2011) which describes relative radial growth over the season. We tested four sigmoid functions (Kumaraswamy (equation 1), Weibull (equation 2), Gompertz (equation 3) and logistic (equation 4)) to model the intra-annual growth dynamics. Guided by the nature of the seasonal growth process of trees, we chose the Kumaraswamy function to estimate the cumulative relative radial growth of trees. For silver birch, this function also had the smallest residual standard error on Vitas’ (2011) data, however, for conifers, a statistically better fit was obtained with the Weibull function (Table 2, Figure 1).For the selected function to correctly determine the course of growth, the beginning (onset) and end of growth are necessary to ascertain, but currently these data are still not available for Estonia. Thus, we used the published research data from neighbouring countries, Lithuania and Finland (Table 1). Since Estonia is located north of Lithuania, the growing season in Estonia probably starts later and ends earlier. There are several studies about Finland where the seasonal growth of trees should start later and end earlier than in Estonia (Jyske et al., 2014; Mäkinen et al., 2008; Schmitt et al., 2004). The data of the beginning (A) and end (B) of the seasonal radial growth of trees collected from the scientific literature (Table 1) were approximated with a linear model (equation 5). The linear model (equation 5) results (Table 3, Figure 2) revealed that the beginning and end of the seasonal radial growth of the trees depend on the geographical latitude (LAT) and the measurement method (M). The effect of the tree species (PL) factor was not statistically significant in this model.By predicting the onset A and end B of the seasonal radial growth with equation 5 for Estonian conditions (geographic north latitude 58.5 degrees and dendrometer method), we obtained 132.2 and 238.5, respectively, for Scots pine, 132.2 and 234.1 for Norway spruce and 134.6 and 233.7 days for silver birch from the beginning of the year. Using the above estimates, Figure 3 presents the model predictions of the seasonal relative radial growth with the Kumaraswamy function (equation 1, Table 2) for Estonian conditions.The beginning and end of the growth period varies from year to year (Tarand et al., 2013). Our model is universal, so the user can determine the start and end day of growth according to the weather conditions and geographical location (Western Estonian islands vs South-Eastern Estonia). Further research is needed for this.In order to obtain a more accurate model of intraseasonal growth dynamics and for other tree species in Estonia, it is necessary to carry out long-term, labour-intensive research.

  • The impact of soil warming on fine root trait responses of trees,
           deciduous vs. coniferous: a meta-analysis

    • Abstract: We compiled data from 149 paired observations from 43 publications and performed a meta-analysis to evaluate the variability of trees’ fine root trait responses under various global soil warming experiments. The impacts of warming magnitude, soil depth, and different tree species (deciduous vs. coniferous), on the responses of fine root biomass (FRB), and fine root morphology were assessed in this study. Our results confirmed that soil warming increased FRB while having no significant effect on fine root morphological traits, such as specific root length (SRL), specific root area (SRA), and diameter (D). The effect of warming on FRB decreased significantly at higher warming magnitude. The effect of tree species was also evident in the response of FRB to soil warming magnitude. Furthermore, warming effects on SRA and D increased in deeper soil horizons. The present meta-analysis provides an improved understanding of trees’ fine roots and the tree species-specific adaptive strategy under future soil warming episodes. Our results suggest that trees will resist the altering soil warming conditions by modifications more in fine root biomass allocation rather than morphological adjustments.

  • Diversity and management of homestead resources: The case of Sandwip
           Upazila, Chittagong, Bangladesh

    • Abstract: Homestead resource utilization is widespread in Asia, while centuries of traditional approaches have been increasing throughout South Asia. Homestead resources are vital to maintaining sustainable life and livelihood of local people in Bangladesh and people in remote areas as coastal zones are mostly engaged with their homestead resources. The study was conducted in Sandwip Upazila (sub-district) of Chittagong district to assess the diversity of plant species, species richness, homestead management practices, and their contribution to the socio-economic condition of the rural households. Ninety household interviews were conducted using a semi-structured questionnaire following stratified sampling to fulfill objectives. A total of 57 tree species under 28 families, including timber, fruits, fuel wood, and multi-purpose tree species were found in the study area. Among the identified 57 tree species under 28 families, 49% are fruit species, while the mean value of Shannon-Wiener Index and evenness of species were 3.32 and 1.89, respectively. Also, the Species Richness Index for Maitbhanga and Sarikait unions was 15.20 and 15.36, respectively, while 52% of the respondents identified market or private nurseries as their source of planting materials. Besides, 71.11% of the respondents replied that protection measures are taken for protecting planting seedlings, while seedlings were used mostly for a better survival rate. Damaged by animals, storms, and pests were identified as most problems faced by households in homestead resource management. This study may help policymakers, including local communities to take proper necessary actions to ensure sustainable management of diversity of homestead resources in local areas of Bangladesh.

           years after clear-cutting'

    • Abstract: The tropical rainforest of Bajo Calima, Buenaventura, Colombia, was known for its large biodiversity and enormous regeneration potential. During the 1970–90s, industrial use through clear-cutting gave rise to secondary forest (SF), which is now a collective property of the communities that inhabit it. The productivity of secondary forest would recover after 30 years according to the linear recovery trend, as predicted by Mazuera (1985). The purpose of conducting this research in Bajo Calima, Colombia was to quantify the productivity of SF at different ages after clear-cutting. Plots of 0.1 ha were selected after 23, 27, 31 and 35 years of SF following clear-cutting of the initial primary forest (PF). It is now managed through selective logging. Samples of equal size of PF and SF without selective logging, called mature secondary forest MSF (> 40 years), were used as controls. The productivity variables of the SF expressed as basal area, volume (Vol) and aerial biomass (AB), on average for the four ages studied was 45%, 29% and 22% compared to the productivity of the PF, and 94%, 50% and 49% with respect to the productivity of the MSF. Without the opportunity to reach maturity the trend predicted by the recovery model was not achieved and the SF showed productive characteristics far below those of the initial primary forest.

  • Eesti sürjametsad; nende tüübid ja indikaatorliigid

    • Abstract: The aims of the study were: (i) to examine how well the hillock forests are distinguishable from the forests of comparable site types, (ii) to ascertain the hillock forest indicator species, (iii) to elucidate the hillock forests’ community types, (iv) to assess the practical requirement for differentiation of hillock forests as a self-sufficient typological unit for forestry. The data included altogether 160 descriptions of hillock forest communities and 42 relevés of other site type stands for comparison. The historical continuity of hillock forests was estimated from old topographic maps. We established that the hillock forests constitute statistically a reliable distinct group of forests. Among the characteristic species having an indicator value significance level of up to 0.50, by the ecological strategy 43.2% belong to competitors, 37.8% are competitors and stress-tolerant ruderals, and 10.8% competitors and stress tolerators; according to the hemeroby, 62.5% of these species are apophyts and 30.0% hemeradiaphors. Most hillock forests (55.6%) are located on former slash-and-burn areas (bushlands) or reforested agricultural land (36.1%). The hillock forests can be classified into four forest types: 1) Fragaria vesca–Festuca ovina–Pinus sylvestris type, 2) Fragaria vesca–Oxalis acetosella–Pinus sylvestris type, 3) Fragaria vesca–Viola mirabilis–Picea abies–Populus tremula type and, 4) Fragaria vesca–Equisetum pratense–Betula pendula type. There is no need to define the hillock forests as a separate forest site type in practical forest typology, nevertheless recognition of these forests as representing the habitat directive type 9060 is important from the viewpoint of biodiversity maintenance.

  • Puistu ruumilise struktuuri arvutuslik kirjeldamine

    • Abstract: As the focus in forestry is moving from timber production to prioritized economic benefits and better integration of ecological-social functions, practical forest management is shifting towards promoting diverse stand structures. Promoting stand structural heterogeneity requires accurate and profound evaluations of spatial stand structure that are generally not provided during conventional forest inventories. In this paper, different indices describing the heterogeneity of the stand and the spatial arrangement of trees, including their size, condition and species were assessed. Indices were applied to the inventory data collected from the Estonian Network of Forest Research Plots. The results show that the studied structural indices are useful in assessment of Estonian forest stands. The practical importance of structural indices will increase in future as there will be a need for methods for characterizing forest stand structural diversity at a large scale, for example, derived from high-resolution remote sensing data.

  • Alien trees and shrubs of Latvia – evaluation of current status and
           invasiveness

    • Abstract: This article presents an updated list of annotated invasive trees and shrubs in Latvia. This list includes 178 taxa about which extensive information has been collected and analysed: family, first records in the area, native range, invasiveness status, vector of introduction, and species distribution in Latvia. In this article, the authors, for the first time in Latvia, provided an invasiveness risk assessment and distinguished risk classes for trees and shrubs. The methodology previously developed by E. Weber and D. Gut was used to assess the risk of invasiveness. The most widely represented families in the list of invasive trees and shrubs are Rosaceae (51 taxa or 28.65%) and Salicaceae (20 taxa or 11.24%). Having assessed the invasiveness status, two species (Acer negundo L. and Sorbaria sorbifolia (L.) A. Braun) were identified as transformers, and 42 tree and shrub taxa were identified as invasive. After the assessment of the invasiveness risk, the species were divided into three risk classes. The highest risk class includes 32 taxa that are threatening or are likely to threaten natural habitats in Latvia in the future. The results of this study can be used for further dendrological studies in relation to global change and for practical nature conservation and landscape gardening.

  • Järvselja metsade tormikahjustuste seire mehitamata
           õhusõidukitega

    • Abstract: This paper provides an overview of a small research project. The object of the research was a 16 km2 forested area located in the territory of Järvselja Study and Experimental Forest, Estonia, which was damaged by storms in June 2021. The aim of the study was to investigate whether it is possible and reasonable to estimate the area of storm damage using orthophotos created from photographs collected from unmanned aircraft. The surveying was carried out on July 13–15, 2021. The data was collected via unmanned aerial vehicles with RGB-cameras on board. A multi-rotor drone DJI Phantom 3 Professional and a fixed-wing unmanned aircraft eBee X were used. In total, the eBee drone was flown 11 times to obtain 11,989 photos and the DJI drone 18 times to obtain 2,471 photos. During the project, it became clear that if there are open fields available, it is more efficient to use a fixed-wing type drone for this kind of research. However, in more difficult conditions where there are no clearances suitable for take-off and landing, a multi-rotor drone, such as the DJI, can be used instead. It can be concluded from the results of the work that although it is possible to use an unmanned aircraft for aerial photography of large forested areas, it takes a considerable amount of time for both photography and post-processing. It took 96 man-hours to collect the data and four working weeks to process the data.
