DAVID Lindenmayer and Jerry Franklin are the two most influential forest conservation biologists of the past decade and will probably remain so for the coming decade. Each has contributed significantly to forest research, management, biodiversity conservation and policy. Lindenmayer is an Australian based at the Australian National University in Canberra who has worked mainly in the temperate eucalypt forests of Victoria and southeastern New South Wales. Most of his research is wildlife oriented, with an emphasis on arboreal marsupials and the impacts of forest management on forest vertebrates. Franklin is an American at the University of Washington, Seattle in the Pacific Northwest. His research is more botanically oriented, with an emphasis on the impacts of forest management on forest structures (e.g., large trees and logs) and processes. Of the two, Franklin has had the greatest involvement in the political, economic and social processes driving the modern change in forestry practices and attitudes. Together they form a formidable team to present a summary and an analysis of how temperate forests globally can and should be managed. Their goal is not just to enhance biodiversity and other ecological values, but to ensure the long-term sustainability of forest ecosystems. Only when forests are managed sustainably to protect biodiversity can forest managers guarantee the many social and economic benefits derived from the world’s forests, including wood production.

Research highlights—Feedbacks between fire severity, vegetation structure and ecosystem flammability are understudied in highly fire-tolerant forests that are dominated by epicormic resprouters. We examined the relationships between the severity of two overlapping fires in a resprouting eucalypt forest and the subsequent effect of fire severity on fuel structure. We found that the likelihood of a canopy fire was the highest in areas that had previously been exposed to a high level of canopy scorch or consumption. Fuel structure was sensitive to the time since the previous canopy fire, but not the number of canopy fires. Background and Objectives—Feedbacks between fire and vegetation may constrain or amplify the effect of climate change on future wildfire behaviour. Such feedbacks have been poorly studied in forests dominated by highly fire-tolerant epicormic resprouters. Here, we conducted a case study based on two overlapping fires within a eucalypt forest that was dominated by epicormic resprouters to examine (1) whether past wildfire severity affects future wildfire severity, and (2) how combinations of understorey fire and canopy fire within reburnt areas affect fuel properties. Materials and Methods—The study focused on ≈77,000 ha of forest in south-eastern Australia that was burnt by a wildfire in 2007 and reburnt in 2013. The study system was dominated by eucalyptus trees that can resprout epicormically following fires that substantially scorch or consume foliage in the canopy layer. We used satellite-derived mapping to assess whether the severity of the 2013 fire was affected by the severity of the 2007 fire. Five levels of fire severity were considered (lowest to highest): unburnt, low canopy scorch, moderate canopy scorch, high canopy scorch and canopy consumption. Field surveys were then used to assess whether combinations of understorey fire (<80% canopy scorch) and canopy fire (>90% canopy consumption) recorded over the 2007 and 2013 fires caused differences in fuel structure. Results—Reburn severity was influenced by antecedent fire severity under severe fire weather, with the likelihood of canopy-consuming fire increasing with increasing antecedent fire severity up to those classes causing a high degree of canopy disturbance (i.e., high canopy scorch or canopy consumption). The increased occurrence of canopy-consuming fire largely came at the expense of the moderate and high canopy scorch classes, suggesting that there was a shift from crown scorch to crown consumption. Antecedent fire severity had little effect on the severity patterns of the 2013 fire under nonsevere fire weather. Areas affected by canopy fire in 2007 and/or 2013 had greater vertical connectivity of fuels than sites that were reburnt by understorey fires, though we found no evidence that repeated canopy fires were having compounding effects on fuel structure. Conclusions—Our case study suggests that exposure to canopy-defoliating fires has the potential to increase the severity of subsequent fires in resprouting eucalypt forests in the short term. We propose that the increased vertical connectivity of fuels caused by resprouting and seedling recruitment were responsible for the elevated fire severity. The effect of antecedent fire severity on reburn severity will likely be constrained by a range of factors, such as fire weather.

This paper presents equations for fuel load and fuel hazard rating (FHR) models based on the time since last fire for dry eucalypt forests in eastern Tasmania. The fuel load equations predict the load of the surface/near-surface and elevated fine fuel. The FHR equations predict the surface, near-surface, combined surface and near-surface, bark, and overall FHR. The utility of the “Overall fuel hazard assessment guide” from Victoria, Australia, is assessed for Tasmanian dry eucalypt forests: we conclude that, when fuel strata components are weighted according to their influence on fire behaviour, the Victorian guide provides a rapid, robust, and effective methodology for estimating FHR. The equations in this paper will be used for operational planning and on-the-ground performing of hazard reduction burning, prediction of fire behaviour for fire risk assessments and bushfire control, and providing inputs into the new Australian Fire Danger Rating System.

On Saturday 7 February 2009, 173 people lost their lives and more than 2000 houses were destroyed in bushfires (wildfires) in the Australian State of Victoria. The scale of life and property loss raised fundamental questions about community bushfire safety in Australia, in particular the appropriateness of the ‘Prepare, stay and defend or leave early’ policy. This paper presents findings from research undertaken as part of the Australian Bushfire Cooperative Research Centre’s (CRC) ‘2009 Victorian Bushfires Research Taskforce’. The research examined factors influencing patterns of life and property loss and survival across the fires through mail surveys (n=1314) of fire affected households. Just over half of the respondents (53%) stayed to defend their homes and properties, whereas the remainder left before or when the fires arrived (43%) or sheltered in a house, structure, vehicle, or outside (4%). Results reveal a survival rate of 77% for houses that were defended by one or more household members, compared to 44% for unattended houses. The paper identifies inadequate planning and preparedness and the tendency for people to wait until they are directly threatened before taking action as major factors leading to late evacuation, failed defence and passive shelter.

Climate warming is expected to increase fire frequency in many productive obligate seeder forests, where repeated high-intensity fire can initiate stand conversion to alternative states with contrasting structure. These vegetation–fire interactions may modify the direct effects of climate warming on the microclimatic conditions that control dead fuel moisture content (FMC), which regulates fire activity in these high-productivity systems. However, despite the well-established role of forest canopies in buffering microclimate, the interaction of FMC, alternative forest states and their role in vegetation–fire feedbacks remain poorly understood. We tested the hypothesis that FMC dynamics across alternative states would vary to an extent meaningful for fire and that FMC differences would be attributable to forest structural variability, with important implications for fire-vegetation feedbacks. FMC was monitored at seven alternative state forested sites that were similar in all aspects except forest type and structure, and two proximate open-weather stations across the Central Highlands in Victoria, Australia. We developed two generalised additive mixed models (GAMMs) using daily independent and autoregressive (i.e., lagged) input data to test the importance of site properties, including lidar-derived forest structure, in predicting FMC from open weather. There were distinct differences in fuel availability (days when FMC < 16%, dry enough to sustain fire) leading to positive and negative fire–vegetation feedbacks across alternative forest states. Both the independent (r2 = 0.551) and autoregressive (r2 = 0.936) models ably predicted FMC from open weather. However, substantial improvement between models when lagged inputs were included demonstrates nonindependence of the automated fuel sticks at the daily level and that understanding the effects of temporal buffering in wet forests is critical to estimating FMC. We observed significant random effects (an analogue for forest structure effects) in both models (p < 0.001), which correlated with forest density metrics such as light penetration index (LPI). This study demonstrates the importance of forest structure in estimating FMC and that across alternative forest states, differences in fuel availability drive vegetation–fire feedbacks with important implications for forest flammability.

Suppression activities on large wildfires are complicated. Existing suppression literature does not take into account this complexity which leaves existing suppression models and measures of resource productivity incomplete. A qualitative descriptive analysis was performed on the suppression activities described in operational documents of 10 large wildfires in Victoria, Australia. A five-stage classification system summarises suppression in the everyday terms of wildfire management. Suppression can be heterogeneous across different sectors with different stages occurring across sectors on the same day. The stages and the underlying 20 suppression tasks identified provide a fundamental description of how suppression resources are being used on large wildfires. We estimate that at least 57% of resource use on our sample of 10 large wildfires falls outside of current suppression modelling and productivity research.

Wildfire management agencies increasingly seek to understand what the public values and expects to be protected from wildfire and its management. Recent conceptual development demonstrates the utility of considering values at three levels of abstraction: localised valued entities such as people, places and objects; valued attributes of communities and landscapes; and core values, or ideals that guide in life. We used a large-scale survey (n = 1105) in Victoria, Australia, to test and extend this framework. The results confirm the usefulness of the conceptual framework and demonstrate that values that members of the public consider at risk of wildfire are much more diverse than those typically considered in wildfire risk management. Relationships between values at different levels of abstraction are meaningful and reveal the multiple ways that objects, places and people become valued. The research suggests ways to understand and practically incorporate values of the public in wildfire management.

Documentation of biodiversity is crucial for examining the health of ecosystems. Many species act as an ecological indicator due to their susceptibility to changes in a particular environment. Butterflies, providing vital ecosystem services, respond uniquely to urbanization and can be a good tool for the assessment of the well-being of the habitat. The present study, one of its first kind in the particular habitat, provides a comprehensive outlook on the species diversity and abundance of butterflies at Victoria Park Reserve Forest, an urban forest area in Bhavnagar, Gujarat, India. The survey was conducted from March 2018 to February 2019 across all seasons. A total of 69 species belonging to 45 genera and five different families were recorded. The most diverse family was Lycaenidae (33.33%), followed by Nymphalidae (31.88%), Pieridae (21.74%), Papilionidae (7.25%), and Hesperiidae (5.80%). Junonia , was the dominant genus with six species. Out of the total recorded species,12 species are listed under the Least Concern category of the IUCN red list and 57 species are Not Evaluated. Seasonal variation in the number of species was observed, which shows the highest number of species in September (n=63) and the lowest in May (n=22). The abundance of the butterfly community was found to be highest during August (26.37%) and the lowest during February (1.85%). This study provided an understanding of the butterfly community in the habitat and would encourage further research for habitat restoration in the reserve forest.

University forests are very important in academic forestry education. They are not only used for the in-forest teaching but also serve for scientific research and public education for people to gain knowledge of forests. Besides these functions, the university forests can also provide social services, such as camping and recreation. People can go into the university forests to enjoy the nature and relax. Taking Beijing Forestry University as an example, this paper will describe the system of university forests in China, their categories, and their roles in forestry education, research and social services. Furthermore, this paper will also explain the development and management system of university forests, and key challenges to the university forests in the future.

Net primary productivity (NPP) is a key ecological parameter that is important in estimating carbon stocks in large forested areas. NPP is estimated using models of which leaf area index (LAI) is a key input. This research computes a variety of ground-based and remote sensing LAI estimation approaches and examines the impact of these estimates on modeled NPP. A relative comparison of ground-based LAI estimates from optical and allometric techniques showed that the integrated LAI-2000 and TRAC method was preferred. Spectral mixture analysis (SMA), accounting for subpixel influences on reflectance, outperformed vegetation indices in LAI prediction from remote sensing. LAI was shown to be the most important variable in modeled NPP in the Kananaskis, Alberta region compared to soil water content (SWC) and climate inputs. The variability in LAI and NPP estimates were not proportional, from which a threshold was suggested where first LAI is limiting than water availability.

Resumo: A conversão de florestas naturais em pastagens, lavouras ou reflorestamentos homogêneos com espécies exóticas, pode influenciar processos ecológicos importantes alterando a dinâmica florestal. O trabalho teve como objetivo avaliar se reflorestamentos homogêneos de Pinus elliottii influenciam a remoção de sementes em uma vegetação secundária de Floresta Ombrófila Mista Montana adjacente. Assim, formulamos três hipóteses: (1) a remoção de sementes será maior na vegetação secundária de Floresta Ombrófila Mista Montana adjacente ao plantio de Pinus elliottii, em especial, onde as plantações se encontram em estágio inicial de desenvolvimento; (2) a remoção de sementes na vegetação secundária de Floresta Ombrófila Mista Montana será maior quanto mais distante da borda com plantio de Pinus elliottii; e (3) a remoção de sementes será diferente entre as espécies de Syagrus romanzoffiana, Araucaria angustifolia e Pinus elliottii. Foram selecionadas seis áreas de plantios de Pinus elliottii adjacentes a vegetação secundária de Floresta Ombrófila Mista Montana. Em cada área foram instalados cinco pontos amostrais, distribuídos ao longo de um transecto a uma distância de 0, 10, 25, 50 e 100 metros da borda florestal. Em cada ponto foram depositadas 13 sementes de cada espécie analisada. O monitoramento das sementes foi realizado após dois, sete, nove, 14 e 21 dias. No geral a taxa de remoção foi elevada para todas as espécies (100% para espécie Syagrus romanzoffiana, 98% para Pinus elliot... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: Conversion of natural forests to pasture, crop or homogeneous reforestation with exotic species can influence important ecological processes by changing the forest dynamics. The objective of this work was to evaluate the effects of Pinus elliottii plantation on seed predation in a Mixed Ombrophilous Montane secondary forest. Thus, we formulate three hypotheses: (1) seed removal will be greater in the Mixed Ombrophilous Montane secondary forest adjacent to Pinus elliottii plantation, especially where the plantations are in early stages; (2) seed removal will be greater in the Mixed Ombrophilous Montane secondary forest farther from the forest edge; and, (3) seed removal will be different among Syagrus romanzoffiana, Araucaria angustifolia and Pinus elliottii species. Six Pinus elliottii areas adjacent to Mixed Ombrophylous Montane secondary forest were selected. In each area, five plots were distributed along 0, 10, 25, 50 and 100 meters from the forest edge. Were deposited 13 seeds by species in each plot. Seeds were monitored during two, seven, nine, 14 and 21 days. In general the removal rate was high for all species (100% for Syagrus romanzoffiana, 98% for Pinus elliottii and 49% for Araucaria angustifolia). Similarly, all distances from the forest edge showed high seed removal, however, Araucaria angustifolia showed reduced seed removal at the edge, with 33% of removal at 0 m against 70% at 100 m. These rates indicate the presence of forest-associated fauna, which may cause predation and/or secondary dispersal. The reduced seed removal of Araucaria angustifolia, a key species for Atlantic Forest, on the forest edge, may indicate losses in the wildlife associated with the forest edge adjacent to the homogeneous planting. In addition, the removal of Pinus elliottii seeds in the forest, if predated, may indicate a reduction of their invasive potential in natural areas.

This is an interdisciplinary arts practice based PhD that incorporates fieldwork into its exploration of Abernethy Forest in Cairngorms National Park, and Culbin Forest in Morayshire, Scotland. The thesis explores how a contemporary arts practice can articulate a place’s multi-layered complexities and how processes of coming to know influence and impact on the kinds of artworks created. This way of working incorporates an innovative approach that draws on geographical, anthropological, historical and ecological sources, and includes the synthesis of a contemporary arts practice with an ethnographic element - more specifically participant observation, with foresters, ecologists and others - as a mode of gathering. Description and examination of encounters in the field give context to the artwork and provide additional knowledge that lends insight into management practices and the knowledge that these workers possess. The research constitutes an original contribution to investigations of the forests of Culbin and Abernethy and correspondingly innovative outputs. This research proposes that a contemporary arts practice can articulate and communicate aspects and elements of place in ways that offer insights to artists, geographers, anthropologists and others. Central to this is the idea that places are multi-layered, everchanging, embodied, active and containing complex ecological, sensorial and physical histories and presences. Communicating these understandings requires a multi-faceted way of working and multi-modal ways of articulation in recognition of place as an experiential field of investigation. The art produced forms a non-linear, multi-stranded body of work that emphasises the benefits of multiple formats within an arts practice. The thesis enhances and further complicates conceptualisations of place that in geography and anthropology are often restricted to academic writing and demonstrates how artists and others can usefully enlarge and expand the ways in which places can be articulated and rendered.

Forestry operations in Sweden can be traced a long way back in history. The overall emphasis has traditionally been on the forests’ economic or profitable role, even though they are also of great ecological and social interests. Nevertheless, the focus has shifted during the last decade due to the impact of sustainable development. A new Forestry Act has now provided the Swedish forestry with a new policy which is guided by two equally-weighted objectives; production and environmental concern. The European Union (EU) has also adapted to the direction of sustainable development. It places particular interest in the creation of sustainable coastal areas within the union.

The aim of the Bachelor of Science thesis was to investigate how Swedish coastal forest owners define their role in the creation of sustainable coastal forests. The study is built on interviews which were conducted with seven forest owners, all of whom have properties in the coastal zones of Östergötland and Kalmar. These two counties are situated in the south-eastern part of Sweden.

The study raises three different issues. The first is the manner in which the informants shape their knowledge of the existing forestry legislation, based on their identities and responsibilities. The second concerns the preconditions with which they are faced when managing their coastal forest properties and whether or not they see the new legislation as a shift in focus. The final issue highlights the importance of local knowledge and looks at the participation of the informants in the development of new regulations.

The following conclusions are drawn from the investigations. Many owners of forest properties do not identify themselves as forest owners; it is therefore important to be aware of this distinction which is made between being a forest owner and being the holder of a forest property. The coastal forest owners who were interviewed run their forests according to their individual situations. Because of this they do not appear to be part of any shift of focus within the Swedish forestry. As a result, they may not have a defined role in its development. This role would probably be clearer or greater if their local knowledge were more explicitly valuated.

Given the neoclassical assumptions of optimizing economic agents, perfect information, perfect competition, and productive efficiency, timber supply is a dynamic process. Different discrete-time dynamic timber supply models and their solution methods are compared and their common elements derived. A continuous-time model is derived, but not solved. The discrete-time timber supply model is then incorporated into a dynamic multi-sector model and a dynamic general equilibrium model. In the multi-sector model, all household's utility functions are aggregated into a single community utility function which is maximized subject to the technology of the economy. The technology for the forest sector is the same as in the discrete-time dynamic timber supply models. Wood is treated as an intermediate input into the production of consumer goods. The technology of the consumer goods sectors is based on the technology used in computable general equilibrium models. The optimal steady state problem for this model is discussed, and the solution for an example problem is presented. Disaggregating the utility function is necessary for modeling true general equilibrium. This greatly complicates the problem of Ending numerical solutions, but enriches the model considerably. The formulation of the general equilibrium model as an optimization problem is described, but proved rather difficult to solve. The optimal steady state problem can be solved using an algorithm developed by Scarf (1967) for finding fixed points of continuous functions. The fixed-point approach provides a reliable solution method and appears to have more potential for modeling departures from perfect competition than the optimization approach. The equivalence of the two approaches is discussed.

In June of 2010, two permanent research plots were established in Forest Park, based on their differing proximities to downtown Portland, Oregon. As part of a long-term ecological research project that seeks to explore the ecological status and human thumbprint on this 5,100 acre forested reserve, the 2010 tree data was investigated for emergent compositional and spatial patterns. Stand composition, tree size, growth rates, and spatial patterns were analyzed, along with ecological and land use histories. Results indicate that the Balch plot, more closely located to the urban center, has different stand composition, condition, and vegetation growth rates, compared to the more rural Miller site. This study supports findings from a study done by Broshot in 2009, where more urban plots demonstrate a different stand composition and recruitment pattern than rural sites. The study is an initial step for exploring questions regarding the ecological status of Forest Park and how land use and disturbance, past and present, shape Portland's forested reserve.

Accounting for multiple changing systems in environmental decision making is challenging and requires balancing several competing priorities. In fire risk, one approach which is increasingly used to capture uncertainty within multiple systems and to prioritise management efforts is Bayesian Network analysis. Here, we have used a Bayesian Network to understand the interactions between ignition likelihood, containment probability, fire behaviour, and fire weather, alongside the subsequent risks to people and property. We developed, populated and tested a Bayesian Network (BN) which classifies the likelihood of outcomes for each of these systems. We then apply this BN to grid of 72,000 potential ignition locations accross Victoria to predict house and life loss values under conditions capturing the top ten worst ranked weather days in the history of each location. We use Phoenix fire behaviour simulations and landscape scale raster data to populate the parent nodes for each ignition and extract the expected values for predicted nodes under different weather scenarios and varying levels of suppression. We found values predicted by the BN broadly matched the spatial patterns of risk produced in Phoenix i.e., areas where risk was highest and lowest in terms of fire area and house loss aligned. However, the values are rescaled by the BN as it takes into account the influence of ignition likelihood and containment probability on risk estimates. The BN is also able to capture uncertainty around the values presented from across the top ten Phoenix simulations, so the recorded values represent the likely outcome for each node given the range of potential weather conditions in those scenarios. We show that BNs can be a useful management tool for estimating fire risks across a range of weather scenarios and locations while still considering ignition likelihood and suppression effectiveness.

Merging fires are known as destructive fires resulting in loss of life and houses. Despite growing efforts in the past decade to understand merging fires, there are still many knowledge gaps about their behaviour, especially at the field scale. In this study, we conducted experimental harvested crop burns in Victoria, Australia, in March and April 2021 to better understand thermal behaviour of merging fire fronts. UAVs with visual and thermal cameras were used to capture high-resolution fire propagation and the combustion process of merging fires. During experiments 50 junction fire fronts (32 forward and 18 backward) and 24 coalescence fire fronts were studied. For thermal analysis, 15 forward and 4 backward junction fire fronts, 6 coalescence fire fronts, and 10 parallel fire fronts were considered. Special methods were developed to process IR footages and compare the combustion process of merging fires and linear fire fronts (head and back fires). To do this, regions of interest (ROIs) containing the merging fire and linear fire front were selected in each frame using FLIR Research Studio. The ROIs were then exported using as bitmask images together with radiometric JPEG image containing both fires. Using the R programming platform, we determined the length and shape of the perimeter of fires for each JPEG image and defined buffer zones within the fire perimeter inside the ROI for each fire for further pixel temperature analysis. Thermal analysis showed that for forward junction fires the median temperature of head linear fire fronts was higher than forward junction fires except towards the end of merging. While in backward junction fires, the proportion of pixels with high temperature was much higher than in back linear fire fronts, indicating much larger burning areas. The temperature distributions of coalescence and parallel fires showed a decrease in the number of high-temperature pixels toward the end of the merge for coalescence and throughout for parallel fires. The fire behaviour observed in the field experiments demonstrates the necessity for better understanding of merging of fire fronts and the relationship between fuel, weather and fire line interaction.

The relation between public and forest changes during the time. Public opinion and interests has considerable influence on decision making regarding forestry. Half of Lithuania’s forests (circa 1.1 mill. ha) has state forest status and are managed by state forest enterprises (SFEs) under confidence rights. One of the most important strategic aims for SFEs is to meet public needs. Yet, public opinion and forestry facts mismatches. Therefore, this study aims to analyse prevailing opinion on forestry practices in state forests managed by Kaišiadorių SFE that are located in Kaišiadoriai municipality. The sociological survey methodology was applied that was conducted involving respondents representing inhabitants over 18th years old. Data was analysed by conducting frequency analysis. Results showed incorrect public opinion concerning with increase of forest coverage, sustainable cutting intensity and increasing environmental consideration. According to opinion of the respondents, the quality of the forests, afforestation and forest sanitary was well improved by Kaišiadorių SFE. It was determined the demand to develop more recreation infrastructure objects in Kaišiadorys municipality forests. The comparison between surveys conducted in 2007 and 2014 showed increasing amount of public that was quite well informed on forestry issues. Also, it determined changes in information sources concerning forestry. Results of the research stressed the necessity of the long-term strategy for the information dissemination.

New York is known as a metropolis of skyscrapers; however less than 1.5% of the 1 million buildings in the city stand over seven stories tall. Over 95% are thought to be of wood-frame or masonry and wood construction.Most of this building stock was constructed using wood sourced from old-growth forests across the eastern seaboard. The city now sits on a stockpile of wood which germinated before New Amsterdam became New York, and which was felled while signatories of the Declaration of Independence were still President; this is structurally valuable hard, dense and high strength-to-weight ratio wood. As our buildings degrade and require renovation or replacement the city must ensure that this resource is not wasted, for environmental and economic reasons.The total number of buildings is large, but because of the rapid and repetitive way that NYC was constructed the variation in building type and structural element sizes across the building population is small. Cross referencing NYC department databases using geographic information systems allowed the Department of Buildings to produce an estimate of the number of buildings in the city of each type. Assessment of historic pattern books, prescriptive regulations, and inspection of existing buildings allows generic estimates of wood dimension and quantity per building type. Combined, this data allows the estimation of the annual rate of release of wood from demolition in NYC - a predicted supply available for future use. A review of existing practices in wood salvage, processing and reuse is then assessed in context, outlining proposals for future local policy and research work.

This article presents results of biology research of two species of Scarabaeidae under the conditions of the Republic of Moldova. The Cetonia aurata development cycle takes place within two years, is a monovoltine spring-summer breeder, hibernates in the adultsand sometime in the larval stage. The adults and larvae lives in plant composts, in decomposed foliage, in rotten roots of plants. Adults sometimes attack inflorescences of fruit trees, so they can be considered pests of orchards, but some larvae live in the soil, consume plant remains and plant composts, so this saprofage species is considered and useful. The second species Protaetia affinis affinis is a mesophyla species with summer-autumn reproduction type, hibernates in the adult stage and larvae, lives in deciduous and semi-degraded vegetal debris from deciduous forests, forests strips, orchards. Species do not cause damage to forestry and agriculture.

Wet soils play an important role in hydrological, biological and chemical processes, and knowledge on their spatial distribution is essential in forestry, agriculture and similar fields. Digital elevation models (DEM) and various hydrological indexes are used to perform water runoff and accumulation processes. The prerequisite for the calculation of the hydrological indexes is the most accurate representation of the Earth’s surface in the DEM, which must be corrected as necessary to remove surface artifacts that create a dam effect. In addition, different resolutions for DEM give different results, so it is necessary to evaluate what resolution data is needed for a particular study. The aim of this study is to evaluate the feasibility of using existing ditch vector data for DEM correction and the resulting implications for soil moisture prediction. Applied methodology uses a network of available ditch vectors and creates gaps in the overlapping parts of the DEM. The data were processed using open source GIS software QGIS, GRASS GIS and Whitebox GAT. Ditch vector data were obtained from JSC Latvian State Forests and the Latvian Geospatial Information Agency. The results show that by applying the bottomless ditch approach in forest lands on moraine deposits, depending on the accuracy of the ditch vector data, the values of the prediction of the soil wetness both increase and decrease. On the other hand, in forest lands on graciolimnic sediments it is visible that predicted soil wetness values increase in the close proximity of ditches. For forest lands on glaciofluvial and eolitic sediments there were no visible changes because of lack of ditches.

In the European Union, forests and other wooded areas cover a total of 177.8 million hectares, which represents approximately 40% of the EU total area and an area similar to that used for agricultural purposes (183.9 million hectares). Germany, Spain, France, Finland and Sweden make up over three-fifths of the area covered by forests in the EU. Our paper shows the distribution of forested areas in the EU and their importance in comparison with the agricultural area of each Member State. In 2014, the EU represents about 12 % of global timber volume harvested timber from forests and woodlands on its surfaces rising to 392.9 million m3. Forestry, logging and related services covering timber production and extraction and harvesting of forest products that grow in the wild. In addition to industrial round wood, forests produce firewood, too. In some regions, non-timber forest products are also an important source of local income. In the research approach, we considered necessary and appropriate to perform a comparative analysis of the situation of Romanian forest similar to that of the main European Union countries, to identify measures that some of them have tried, and even managed to increase a rational exploitation of afforested areas forest resources. The results conducted to a comparative analysis of the National Forest and the main EU countries’ Systems, to identify possible starting points for grounding new sustainable development strategies, given their similar experience.

Communal forests occupy one million hectares in the Northern of Portugal and Galicia. Since centuries ago, “Baldios” and “Montes Veciñais en Man Común” (MVMC) played an essential function in the economy of their owner communities. This role was lost all through the last century due to the enormous afforestation and the decrease of agriculture. The restitution of democratic regimes returned the communal forests tenure to the communities. Given the extension and high average area, our paper aims to research its potentialities and limitations of contribution to rural development. Two case studies, one in North Portugal and another one in Galicia, allow identifying the individual and collective traditional uses and the achievements made with revenues linked. Both Galician and Portuguese realities exhibit similarities and complementary benefits, and needing social and economic innovation to make a better use of rural resilience. Communal lands and small-scale business projects could maintain the network of local produce markets with attractive aesthetic values as well as biodiversity conservation. The comparison of the different criteria shows economic aspects are the most valorised by the stakeholders. The management decision of collective forests was the alternative mixed by the communities and the Forestry Services as the best one to complete the main objective of sustainable rural development. As a final conclusion of our work, remarking that the communities owning these forests currently seem to have the conditions to successfully manage their properties if the commoners are able to mobilize and adequate organize the communities.

Rise in human population, industrialization, urbanization, intensified agriculture and forestry pose considerable risks to water supply and quality both on global and regional scale. While freshwater resources are abundant in Latvia, during recent years increased attention has been devoted to water quality in relation to anthropogenic impacts. Forest cover in Latvia equals 52% and forest management and forest infrastructure building and maintenance are among the activities that may, directly or indirectly, affect water quality in headwater catchments. Sedimentation, eutrophication and export of hazardous substances, especially mercury (Hg), are of highest concern. To address these topics, several initiatives have started recently. In 2011, cooperation programme between Latvian State Forest Research Institute (LSFRI) “Silava” and JSC “Latvia’s State Forests” was launched to evaluate the impact of forest management on the environment. This programme included research on the efficiency of water protection structures used at drainage system maintenance (sedimentation ponds, overland flow) and regeneration felling (bufferzones). In 2016, within the second stage of this cooperation programme, a study on the impact of forest management on water quality (forest road construction, drainage system maintenance, felling) was started on a catchment scale. Since 2016 LSFRI Silava is partner in the Interreg Baltic Sea Region Programme project “Water management in Baltic forests”. By focusing on drainage systems, riparian zones and beaver activity, this project aims at reducing nutrient and Hg export from forestry sites to streams and lakes. While this project mostly has a demonstration character, it will also offer novel results on Hg and methylmercury (MeHg) concentrations in beaver ponds in all participating states. This paper aims at summarizing most important challenges related to the impact of forest management on water quality and corresponding recent initiatives striving to offer solutions.

Forests and forestry are the ecological and economic infrastructure of every state. The EU strategy for the forest-based sector is particularly related to rural development, since, in such areas, forests are mostly spread, thus representing an opportunity for more balanced development, or in other words - survival of rural areas. Croatia is no exemption. The goal of forest management in the Republic of Croatia is the sustainable and harmonious use of all forest functions and the permanent improvement of their condition, by promoting environmentally sustainable production practices in such a way that the local or rural environment has financial benefits. Looking at forests as perfect factories, ranging from the production of wood pulp as raw materials, oxygen and food, water purifiers, carbon tanks and all the way to the intangible and generally useful functions of forests, it is necessary to observe their all-encompassing importance. We are facing global climate change, which significantly influences the restoration and erection of new forest stands, that is one of the most important procedures for sustainable forest management in Croatia. Current techniques and knowledge that are being applied contribute to discouraging results, therefore it is crucial to introduce and promote new environmentally friendly practices, aiming to increase the productive function of forest land and forest as an ecosystem. In accordance with the sustainable development of forest land, research was conducted in the lowland part of Sisak-Moslavina County in Croatia. The aim of the research is to study the cost-effectiveness and compare the adaptation of new methods and practices of reforestation, with the end result of the forested area as a production unit, and that was conducted working on two land sections. On the surface of the first section, which was previously chemically prepared, a classic renovation was performed by sowing acorns employing a spreader. The acorn was collected by the local population. Processing of the second section included planting seedlings, while the section was previously mechanically prepared by grinding biomass and an integral method of soil preparation in rows with a spacing of 3 m. The internal planting distance between the plants was 0.80 - 1.0 m, and work was carried out with the help of external contractors, the local population. The use of new environmentally sustainable technologies has resulted in 29% higher financial costs of forestation. However, using new practices compared to the classical ones, the financial viability in terms of economic profit of the rural area was determined. The application of new silvicultural practices is initially more expensive, but results in a shorter period of time to achieve targeted results, while the increase in costs refers to the involvement of the local community that participated in the works.
