Abstract Purpose of Review Carbon sequestration and storage in forest ecosystems is often promoted as a solution for reducing CO2 concentrations in the atmosphere. Yet, our understanding is lacking regarding how forest management strategies affect the net removal of greenhouse gases and contribute to climate change mitigation. Here, we present a review of carbon sequestration and stock dynamics, following three strategies that are widely used in boreal, temperate and tropical forests: extensive forest management, intensive forest management and old-growth forest conservation. Recent Findings Several studies show that specific forest management strategies can improve carbon sequestration capacity and soil carbon storage. Within these studies, the old-growth forest conservation strategy results in greater carbon storage in soils than do extensive and intensive forest management. Intensive forest management enhances forest carbon sequestration capacity through afforestation using fast-growing species, mechanical soil preparation from low to moderate intensity and N fertilization. Extensive forest management is an intermediate compromise regarding carbon sequestration and soil carbon storage, between conservation and intensive forest management strategies. With respect to silvicultural treatments, partial cutting is a practice that increases forest carbon sequestration rates and maintains higher carbon storage in soils compared to clear-cuts. Each silvicultural practice that is discussed in this review showed a similar effect on forest carbon in all biomes, although the magnitude of these effects differs mainly in terms of heterotrophic respiration. Summary To achieve sustainable management and fulfill industrial demand and profitability, specific gaps must be dealt with to improve our scientific knowledge regarding forest carbon sequestration in a climate change context, mainly through the integration of the three aforementioned strategies in a functional zoning approach at the landscape scale. We present a review with promising strategies for guiding sustainable forest management in such a global context.

We simulated Austrian forests under different sustainable management scenarios. A reference scenario was compared to scenarios focusing on the provision of bioenergy, enhancing the delivery of wood products, and reduced harvesting rates. The standing stock of the stem biomass, carbon in stems, and the soil carbon pool were calculated for the period 2010–2100. We used the forest growth model Câldis and the soil carbon model Yasso07. The wood demand of all scenarios could be satisfied within the simulation period. The reference scenario led to a small decrease of the stem biomass. Scenarios aiming at a supply of more timber decreased the standing stock to a greater extent. Emphasizing the production of bioenergy was successful for several decades but ultimately exhausted the available resources for fuel wood. Lower harvesting rates reduced the standing stock of coniferous and increased the standing stock of deciduous forests. The soil carbon pool was marginally changed by different management strategies. We conclude that the production of long-living wood products is the preferred implementation of climate-smart forestry. The accumulation of carbon in the standing biomass is risky in the case of disturbances. The production of bioenergy is suitable as a byproduct of high value forest products.

About 15% of the area of the Czech Republic is classified as territories with special status of protection, most of which is covered with forests. At present, at the time of integration of the country into the European structures, an increase in the area of such territories by approximately 20% is expected. The territories show significant variation of protection objectives, management restrictions, profound differentiation in natural conditions, structure of ownership and different levels of damage, especially that caused by anthropogenic pressure. This situation requires the formulation of long-term management strategies. The problem can be solved in the following successive steps: formulation of variants and alternatives of management strategies based on a retrospective analysis of forest development; prognosis of the forest condition development after application of the individual management strategies on the basis of growth and development simulations; addition of technological and economical bases; selection of optimal variants and alternatives from the viewpoint of the fulfilment of the owner’s management goals, in accordance with the principles of forest policy and from the viewpoint of the fulfilment of the protection objective formulated for a specific territory with special status of protection. A set of methods for following the above-mentioned steps is specified in the presented contribution.

Forests account for 60% of lands in Taiwan. Climate change impacts forests in many aspects and is increasingly likely to undermine the ability of forests to provide basic ecosystem services. To help reduce the impact of climate change on Taiwan’s forests, people must be made aware of the relationship between climate change and forests. Based on questionnaires collected from 17 cities in Taiwan, this study applied spatial analysis to assess the respondents’ understanding of climate change and adaptation strategies for forest management. A total of 650 questionnaires were distributed and 488 valid ones were collected. The results show that (1) Most respondents believe that climate change is true and more than half of the respondents have experienced extreme weather events, especially extreme rainfall; (2) Most respondents believe that climate change will affect Taiwan’s forests with the majority recognizing the increasing impact of extreme events being the primary cause, followed by changes in the composition of tree species and the deterioration of forest adaptability due to climate change; (3) Most respondents expressed that forest management should be adjusted for climate change and called for measures being taken to establish mixed forests as well as monitoring forest damage; (4) In order to address the difficulties faced by forest owners on the impact of climate change, the majority of respondents felt that the government should raise forest owners’ understanding on climate change and adaptation policies, while the subsidy incentives must also be adjusted. The results of this study show that the respondents do realize the importance of climate change and forest management so much so their awareness in this matter led to their support for forest adaptation measures and policies.

Forests are diverse and complex associations of plant and animal life that are influenced considerably by their environment and man, and by their interactions. Forest pests, including pathogens, form an important component of the forest ecosystem, and their management is an integral part of forest management. There is, however, a need to obtain a better understanding of these pests, and their relationships with plants and other factors in the environment.This article attempts to compile most of the available information about research on major tree diseases in Canada, particularly that which deals with or has led to the development of strategies to control or manage those diseases. A brief information on Canada's forest resource and the losses caused by these diseases and by other damage problems is also included. Key words: forests, tree diseases, research strategies, disease management strategies, disease losses, integrated pest management.

We used novel remote sensing techniques to compare the landscape-scale patterns of forest structure in Pennsylvania, USA under the management of four different agencies with varying primary objectives, including production forestry, wildlife habitat, recreation, and private ownership. We (i) developed a forest structure classification scheme using publicly available LiDAR and orthographic aerial imagery data, (ii) mapped the forest structure across twenty forested landscapes, and (iii) compared the landscape-scale forest structure patterns among the four forest management types. Our results indicate that different management philosophies and their associated forest management approaches have resulted in contrasting landscape-scale patterns of forest structure. Privately managed forests had shorter forests, higher densities of distinct patches, higher interspersion of patch types, and higher forest structure diversity at fine-scales (1.5 ha grain size) compared to forests lightly managed for recreation. Production forests under ecosystem management and forests managed for wildlife habitat exhibited intermediate patterns of forest structure. This variation in forest structure patterns among the forest managers is likely to have implications for wildlife habitat and other ecosystem services. Furthermore, greater emphasis is needed on encouraging private landowners to manage across property boundaries and providing the resources and tools to manage forests at the landscape scale.

Some forest-dependent rural communities participate in the Collaborative Forest Management (CFM) program in South Korea, which provides the local people with access to national forests for the collection of non-timber forest products (NTFPs) in return for their contribution to the management of national forests. This study investigated what factors influenced rural communities’ participation in CFM and how their participation in CFM affected livelihood strategies and income level. Households in 17 villages near the Seoul National University (SNU) forests owned by the Government were interviewed. The study found that CFM participating households tend to choose diversified livelihood strategies. CFM participating households with diversified livelihood strategies are likely to have a higher income than non-CFM participating households choosing sectoral focus strategies. Expansion of the CFM program is suggested as a policy option to improve forest-dependent rural livelihood. However, ageing and female-headed households are faced with difficulties in participating in CFM due to their physical ability of forestry work while new settlers restricted access to forest resources. There is a need for innovation in forest governance for equitable distribution of forest services for both original and new residents to achieve sustainable rural livelihoods.

This dissertation uses the constructivist grounded theory methods of Charmaz (2011) to explore: 1) the unique characteristics of landscape-scale collaboration; 2) implications for collaborative capacity-building strategies; and 3) the relationship between conflict, landscape-scale collaboration, and conflict resolution. The study was conducted through the US Forest Service's Collaborative Forest Landscape Restoration Program (CFLRP). In the 1980s and 1990s, national forest management conflicts brought the forest industry to a standstill, with many jobs lost. In addition, historic fire suppression practices have made our national forests highly vulnerable to catastrophic wildfire. Many have strong opinions about what should be done and how. The proposed substantive theory suggests landscape-scale collaboration can serve as a conflict prevention, problem solving, or conflict resolution venue and offer opportunities for remarkable efficiencies in forest restoration as well as profoundly restorative transformation in ecological, social, economic, personal, and spiritual dimensions. It identifies unique characteristics of collaboration at this scale; suggests that realizing benefits depends on collaborative capacities at the collaborator, constituent organization, collaborative stakeholder group, and sponsoring organization levels, and on mastering nine challenges; and suggests eight implications for collaborative capacity building strategies. The study contributes to forest restoration, reduced loss of life and livelihood, and economic recovery by contributing to CFLRP effectiveness. It contributes to the field of conflict resolution by: illuminating the collaboration / conflict resolution relationship; a particular application of collaboration; related sources of conflict; and conflict resolution strategies. It advances new directions of study for conflict resolution scholars--i.e., how to help agencies and groups strengthen their collaborative capacities.

There is limited information on how young-growth giant sequoia (Sequoiadendron giganteum [Lindl.] Buchholz)/mixed conifer stands respond to forest management strategies. An applied research study was initiated in 1989 when 35 approximately 0.1 acre (0.04 hectare) plots were installed in six young-growth giant sequoia/mixed conifer stands. The objective of this study was to determine if there was a difference after 20 years between treatments (a) thin only, (b) thin and prescribe burn, and (c) control in terms of the effect on overstory growth and yield, understory plants, tree regeneration and downed woody debris. Analysis of variance (ANOVA) for cubic-foot growth over 20 years showed significant difference (p = 0.016) between the three treatments. Three diversity indices (richness, evenness, and heterogeneity) showed varied results with environmental factors of slope and elevation major variables affecting plant diversity. Regeneration study showed significant seedlings per acre difference (p = 0.010) between treatment (b) and treatments (a) and (c) with white fir (Abies concolor [Gord. & Glend.] Lindl. ex Hildebr.) the majority at 87%. These collected and analyzed data will benefit Mountain Home Demonstration State Forest along with other forest managers who actively manage giant sequoia stands, whether natural or plantation.

Despite decades of varied conservation and management interventions, tropical forests remain one of the world’s most threatened biomes. Tropical forests directly support the livelihoods of millions of people in poverty through the provision of food and fuel, while also delivering vital ecosystem services such as carbon sequestration and watershed protection. Approaches to conserve and manage tropical forests have evolved in recent decades, reflecting an increasing appreciation for the multiple ecological, social and economic services they provide. However, growing appreciation for the multiple benefits of forests has arguably not been met with their growing realisation in practice. Indeed, it is becoming apparent that trade-offs in forest conservation and management are common, whereas ‘win-win’ outcomes for both development and conservation are rare. Despite this, emerging policies aimed at reducing emissions from deforestation and degradation (REDD+) have harnessed international attention, given theoretical benefits not just for climate change mitigation, but biodiversity conservation and poverty alleviation. For REDD+ to succeed where other policies arguably have failed, critical examination of existing tropical forest conservation and management policies is necessary to provide implementation recommendations. In this thesis I critically review the history of interventions to conserve and manage tropical forests (Chapter 2), and highlight three repeated failures in implementation that are common to all examined policies: low appreciation by management for the heterogeneity of target communities and dependence on forest resources; low levels of community inclusion and participation in management; and a continued deficit in clearly defined social and economic indicators of intervention success. To address these concerns I suggest examination of policy implementation at the local level is needed, with focus on what works where, for whom, and why, rather than what the ‘silver bullet’ for tropical forest conservation and management might be. Using a case-study approach in Tanzania, I examine the implementation of different management regimes, including strict protection and Participatory Forest Management (PFM), from the local socio-economic perspective. In the first empirical chapter (Chapter 3), I measure household awareness of the different forest management regimes in the study area using household questionnaire surveys. Results show that awareness of forest management and rules and regulations was clear, however confusion in the type of regime in place was apparent. Overall, awareness for top-down management structures was high, yet few households were engaged in rule formation of the PFM forests and none were aware of joint-management status. Findings indicate that forest management implementation must consider heterogeneity in villager awareness for management regimes, yet logistic regression models show this heterogeneity cannot necessarily be defined in a predictable way based on household socio-economic characteristics. Management implementation that focuses on transparent, uniform and consistent communication of information across whole forest- adjacent communities is therefore more likely to succeed. In the second empirical chapter (Chapter 4), I quantify household forest product use in the study area to examine the impact of forest access restrictions on household ability to meet firewood needs. Household perceived need for firewood was compared with quantity consumed to provide an indication of household firewood sufficiency. Results indicate management effectiveness is reflected by this measure of firewood sufficiency. Harvest from non-forest areas was found to significantly reduce firewood sufficiency, presenting concerns for household welfare and/or leakage of harvesting activities to other less-well protected forests in the area given a recent ban on firewood collection in a nearby National Park. Results of this chapter support suggestions that forest management adopt a landscape approach in planning, to account for local resource needs and avoid the negative impacts of leakage and detriment to local welfare. Finally, in Chapter 5 I use a qualitative approach to examine local perceptions of the challenges for forest protection, and compare these across stakeholder groups from the villager to management level. Issues that permeate the discourses are categorised into three themes: education, governance and forest dependency. The importance of each issue was found to vary by stakeholder group, identifying a disconnect and division in accountability for forest protection between villagers and management officials. Results suggest more novel approaches for social engagement and community inclusion in forest management are necessary. I suggest that facilitation of villager empowerment is needed for village institutions to be effectively accountable for forest protection, thereby aiding long term management success. Overall, the thesis shows that forest conservation and management interventions need to account for the perspectives and needs of local forest-adjacent communities. In Chapter 6, results are discussed in light of the three repeated failings of tropical forest conservation and management interventions, as outlined in Chapter 2. Results confirm these failings in implementation exist in the study area. As such, I suggest that the local socio-economic measures used in this thesis can be used in future evaluations of global tropical forest policy. Results also present important implications for emerging REDD+ policies, as limits to achieving the multiple benefits of climate change mitigation, biodiversity conservation, and poverty alleviation are identified.

Streszczenie:
Dispersed recreation management is a form of management that has emerged over the past century of outdoor recreation management on public lands in the United States. Techniques used in dispersed recreation management seek to disperse recreation use, recreational areas, and their impacts across landscapes and ecosystems or to concentrate such use to areas that remain undeveloped. This study is a mixed-methods, descriptive study of dispersed recreation management on national forest lands. In particular, this study focuses on United States Forest Service (USFS) management Concentrated Use Areas (CUAs) on Uinta-Wasatch-Cache National Forest (UWCNF), as identified in the 2003 Revised Forest Plan of the Wasatch-Cache National Forest. A qualitative approach of inventorying past management actions, observing CUAs, and interviewing recreation managers and resource specialists on the UWCNF was used. The qualitative aspects of this study were also coupled with a quantitative analysis of Geographic Positioning System (GPS) based data using Geographic Information Systems (GIS) to better understand characteristics of CUAs and their management in dispersed recreation settings. Overall, this study draws many conclusions involving the definition of, and management and design solutions for CUAs. CUAs can be described as easily accessible, flat areas adjacent to roads, with good access to water, and shade. These areas are often used for camping of various types, with trailers and groups being a predominant use. ATVs and motorized use are also associated with these areas. Use is generally considered high and continual during the summer season, with sites often being used year after year by families and groups of friends. Loss of vegetation, soil compaction, and soil erosion are common impacts attributed to concentrated recreational use. Another finding was that recreation resource managers and resource specialists have similar views of what CUAs are and how they are managed. Management actions generally consist of both indirect and direct management actions focused on limiting environmental impacts caused by recreation uses. Management actions are conducted on both large and small scales within districts, and dispersed recreation protocol was found that called on management to reduce biophysical impacts. However, management techniques lack official targets and metrics for measuring the success of management. Design is also a component of CUA management. The design of CUAs generally consists of adapting user-created recreation areas into more structured and defined areas.

Ghana has experienced a remarkable degradation and depletion of its forest resources over the last 100 years. This process has undermined the socio-economic and socio-cultural importance of the forests for millions of rural people who depend on the resource to support their livelihood. Many rural households have over the past three decades developed strategies to minimize the effects of forest depletion on their livelihood. The establishment of smallholder forest plantation on agricultural land has emerged as an important form of land-use for households to diversify their sources of income and also improve their socio-economic well-being. The main objective of the study was to identify and analyze the endogenous and exogenous factors inducing farm household’s decision to establish farm forest plantation and to analyze its financial contribution to household’s income and livelihood strategies. The study involved a survey of 280 randomly selected farm households from five communities in the Offinso district in Ghana. The multi-stage stratified random sampling technique was used to select as many as 165 households with farm forest plantation as well as 115 without farm forest plantation. A mixture of tools including semi-structured questionnaire, focus group discussions, wealth ranking, forest inventory and market surveys were used to collect the required data. Results from logistic regression analysis revealed that the age of the household head, the number of years of education of the household head, the amount of household labor, the size of household landholding, the ownership of permanent land, the availability of non-agricultural land and household’s participation in past forest plantation development projects are the most important endogenous factors influencing the farm household’s decision to establish farm forest plantation. On the other hand, exogenous factors such as the availability of market and buyers for farm forest products and farm household’s satisfaction with market prices for farm forest products positively influenced the household’s decision to establish farm forest plantation. Prohibitive rules and regulations relating to the harvesting of trees and transportation of timber from private lands and uncertainty in tree tenure as a result of ambiguous policy framework, however, negatively influenced the decision to establish smallholder forest plantation on their agricultural land. The results from household income portfolio analysis show that cash income from selling farm forest products contributed an average of $273.6 to total household’s income in one agricultural season. This amount accounted for 17.6% of total household’s income and represented the second most important source of income after agriculture. The profitability of different land-uses practiced by the households was analyzed using a conventional economic method (Net Present Value). The results from a comparative financial analysis show that the establishment of teak plantation on agricultural land inter-cropped with food crops is the most profitable form of land use for the households compared to pure teak plantation and maize-plantain cultivation. The results of the study underscore the potential contribution of smallholder farm forest plantation to increase the overall household’s income and thereby improve household’s well-being
Ghana hat während der letzten 100 Jahre eine bemerkenswerte Degradation und Verminderung seines Waldvorkommens erlebt. Dieser Prozess hat die sozio-ökonomische und sozial-kulturelle Bedeutung des Waldes als Einkommensquelle zur Unterstützung des Lebensunterhalts für Millionen ländlicher Einwohner geschwächt. Während der letzen 30 Jahre haben viele Kleinbauern Haushalte Strategien entwickelt um den Effekt, den die Verminderung des Waldvorkommens auf ihren Lebensunterhalt hat, zu minimieren. Die Anlage kleinflächiger Forstplantagen auf Ackerland hat sich dabei als wichtige Form der Landnutzung erwiesen, da sie eine Einkommensquelle zusätzlich zu den vorhandenen bedeuten. Sie haben das Potential, die sozio-ökonomiche Situation der Bevölkerung zu verbessern. Ziel der Studie war die Identifizierung von internen und externen Faktoren, die bedeutend zur Entscheidung von Haushalten über die Errichtung kleinflächiger Forstplantagen beitragen. Desweiteren sollten der finanzielle Beitrag der Forstplantagen zum Einkommen und zu Strategien der Kleinbauern analysiert werden. Für die Sudie werden Datensätze von 280 zufällig ausgewählten landwirtschaftlichen Haushalten aus fünf Gemeinden im Offinso Distrikt in Ghana erfasst. Die mehrstufig aufgebaute zufällige Auswahltechnik wurde benutzt, um die 165 Haushalte mit Forstplantagen und 115 Haushalten ohne Forstplantagen für die Studie auszuwählen. Mehrere Instrumente, wurden genutzt um die benötigten Daten zu sammeln darunter vor allem semi-strukturierte Befragungen, fokusierte Gruppendiskussionen, Wohlstandsranking der Haushalte und eine Forstinventur. Ergebnisse einer logistischen Regressionsanalyse ergaben, dass das Alter des Haushaltsvorstands, die Anzahl der Ausbildungsjahre des Haushaltsvorstands, die Anzahl der im Haushalt vorhandenen Arbeitskräfte, die Größe des dem Haushalt zur Verfügung stehenden Ackerlandes, das Eigentum an Ackerland, verfügbare nicht-landwirtschaftlich nutzbare Flächen und die Teilnahme der Haushalte an Projekten zur Forstplantagenentwicklung die wichtigsten internen Faktoren für die Entscheidung der Kleinbauern zur Errichtung von kleinflächiger Forstpantagen darstellen. Andererseits beeinflussten externe Faktoren wie das Vorhandensein von Markt und Käufern für Produkte der Forstplantagen und die Zufriedenheit der Haushalte mit den gebotenen Marktpreisen für diese Produkte die Entscheidung der Kleinbauern zur Errichtung von Forstplantagen positiv. Demgegenüber beeinflussten Verbote und einschränkende Regelungen zur Ernte und zum Transport von Bäumen auf Privatland und die Unsicherheit bezüglich des Eigentums an den Bäumen als Ergebniss unklarer politischer Vorgaben die Entscheidung zur Errichtung von kleinflächiger Forstplantagen auf Ackerland negativ. Das Ergebniss der Analyse verschiedene Haushaltseinkommensquellen zeigt, dass das Jahreseinkommen der Haushalte mit Forstplantagen höher ist als das der Haushalte ohne Forstplantagen. Der Beitrag zum Jahreseinkommen aus dem Verkauf von Produkten der kleinflächiger Forstplantagen betrug im Durchschnitt 273,6 USD in einer landwirtschaftlichen Saison. Dies entsprach 17,6 % des gesamten Haushaltseinkommens und stellte somit die zweitwichtigste Einkommensquelle nach der Landwirtschaft dar. Die Rentabilität der verschiedenen Landnutzungsarten wurde mit der Kapitalwertmethode (Net Present Value) ermittelt. Diese vergleichende Analyse zeigte, dass kleinflächiger Forstplantagen auf Agrarland bei gleichzeitigem Anbau von Nahrungsmittel die profitabelste Art der Landnutzung für die Haushalte im Vergeich zu ausschließlichem Teakanbau und zum Anbau von Mais mit Kochbanane ist. Die Ergebnisse der Studie unterstreichen das Potential kleinflächiger Forstplantagen, einen Beitrag zur Steigerung des gesamten Haushaltseinkommens und zur Verbesserung des Lebensstandards der Haushalte leisten zu können

Development of effective methods for studying the composition, diversity, and behavior of microorganisms in soil habitats is essential for a broader understanding of soil quality. Forest management strategies and practices are of vital significance for sustainable forest production. How the different forest management measures will influence soil microbial communities is a widespread concern of forest industry and scientific communities. Only a small proportion (~0.1%) of the bacteria from natural habitats can be cultured on laboratory growth media. Direct extraction of whole-community DNA from soil, followed by polymerase chain reaction (PCR) and other analysis circumvents the problems of the culture-dependent methods and may shed light on a broader range of microbial communities in the soil. DNA-based molecular methods rely on high quality soil microbial DNA as template, and thus extraction of good quality DNA from soil samples has been a challenge because of the complex and heterogeneous nature of the soil matrix. The objectives of this research were to establish a set of DNA-based molecular methods and to apply them to investigate forest soil microbial composition and diversity. Soil samples were collected from different forest ecosystems, i.e., the natural forest (YNF) and the first rotation (~ 50 years) (Y1R) and the second rotation (~ 1 year) (Y2R) of hoop pine plantations at Yarraman, and from different forest residue management practices (the experiments had established 6.4 years before the samples were collected) at Gympie, two long-term experimental sites of the Queensland Department of Primary Industry-Forestry in subtropical Queensland, Australia. Some DNA-based molecular techniques, including DNA extraction and purification, PCR amplification, DNA screening, cloning, sequencing and phylogenetic analyses, were explored using Yarraman soil samples, which were high in organic matter, clay and iron oxide contents. A set of methods was assembled based on the recommendations of the method development experiments and applied to the investigations of the microbial composition and diversity of the Yarraman and Gympie soil samples. Four soil DNA extraction methods, including the Zhou method (Zhou et al., 1996), the Holben method (Holben, 1994), the UltraClean (Mo Bio) and FastDNA (Bio 101) soil DNA extraction kits, were explored. It was necessary to modify these methods for Yarraman soil. I designed and introduced a pre-lysis buffer washing step, to partially remove soil humic substances and promote soil dispersion. This modification greatly improved the quality of the extracted DNA, decreasing co-extracted humic substances by 31% and increasing DNA yield by 24%. The improved Holben method was recommended for fungal community studies, and the improved Zhou method for bacterial community studies. The extracted DNA was good in quality, with a consistent size of ~20 kb and a yield of 48-87 g g-1 soil, and could be successfully used for 16S (Zhou method) and 18S (Holben method) rDNA amplifications. For less difficult environmental samples, UltraClean kits could be a good option, because they are simple and fast and the extracted DNA are also of good quality. Screening of the DNA PCR products using TGGE, Heteroduplex-TGGE and SSCP was also explored. These methods were not so effective for the screening of the soil DNA PCR products, owing to the difficulty in interpretation of the results. Cloning was a necessary step to obtain a single sequence at species level in soil microbial community studies. The screening of the clone library by TGGE, Heteroduplex-TGGE and SSCP could only separate the clones into several major bands, although SSCP gave better separation. Sequencing of selected clones directly from the clone library obtained ultimate results of microbial taxonomic composition and diversity through well-established sequence analysis software packages and the databases. It was recommended that, in this project with the target of microbial community composition and diversity, soil DNA PCR products were directly cloned to construct clone libraries and a sample of clones were sequenced to achieve an estimate of the taxonomic composition of the soil. Fungal communities of the Yarraman soil samples under the natural forest (YNF) and the hoop pine plantations (YHP) were investigated using 18S rDNA based cloning and sequencing approaches. Twenty-eight clone sequences were obtained and analysed. Three fungal orders, i.e., Zygomycota, Ascomycota and Basidiomycota were detected from the YNF and YHP samples. By contrast, culture-based analyses of fungi in the literature were mostly Ascomycetes. YNF appeared to have more Ascomycota but less Zygomycota than YHP, and within the Zygomycota order, YHP had more unidentified species than YNF. Bacterial communities of Yarraman soil samples of YNF, Y1R and Y2R were investigated using 16S rDNA-based cloning and sequencing approaches. 305 16S rDNA clone sequences were analysed and showed an overall bacterial community composition of Unclassified bacteria (34.4%), Proteobacteria (22.0%), Verrucomicrobia (15.7%), Acidobacteria (10.2%), Chloroflexi (6.9%), Gemmatimonadetes (5.6%), and Actinobacteria (5.2%). There was a significant difference among YNF, Y1R and Y2R in the taxonomic group composition. YNF had a greater proportion of Acidobacteria (18.0%), Verrucomicrobia (23.0%) and Chloroflexi (9.0%) than Y1R and Y2R (corresponding to 6.3%, 12.1% and 5.9%, respectively), while Y1R and Y2R had a higher percentage of the Unclassified group (38.5% for Y1R and 46.5% for Y2R) than YNF (18.0%). For the Proteobacteria group, YNF had more Alpha-subdivision but Y1R and Y2R had more Delta-subdivision. From YNF to Y1R to Y2R, the clone sequence variable site ratios, 5% and 10% OTU numbers and Shannon's diversity index H' values tended to decrease, indicating the soil bacterial diversity decreased from the natural forest to the first and the second rotation hoop pine plantations. The large amount of unclassified clone sequences could imply a novel group of bacteria in the soil, particularly in the hoop pine soil samples. Alternatively they may result from artefacts during the PCR process. Bacterial communities of the Gympie soil under different residue management practices, i.e., residue (litter plus logging residue) removed (G0R), residue retained (G1R), and residue doubled (G2R), were also investigated using the 16S rDNA-based cloning and sequencing approaches. Acidobacteria (37.6%) and Proteobacteria (35.6%, including Alpha-subdivision of 29.9% and Gamma-subdivision of 5.7%) were dominant components of the communities, followed by Actinobacteria (14.7%), Verrucomicrobia (7.3%) and Unclassified bacteria. There was no significant difference among G0R, G1R and G2R in the bacterial community compositions and diversity. These findings provided an in-depth vision of the soil microbial communities under different forest management practices. Their combination with other soil analysis results, such as physical and chemical properties, and forest production data, could provide an improved understanding of sustainable forest management strategies.

Effective short-term load forecasting (STLF) plays an important role in demand-side management and power system operations. In this paper, STLF with three aggregation strategies are developed, which are information aggregation (IA), model aggregation (MA), and hierarchy aggregation (HA). The IA, MA, and HA strategies aggregate inputs, models, and forecasts, respectively, at different stages in the forecasting process. To verify the effectiveness of the three aggregation STLF, a set of 10 models based on 4 machine learning algorithms, i.e., artificial neural network, support vector machine, gradient boosting machine, and random forest, are developed in each aggregation group to predict 1-hour-ahead load. Case studies based on 2-year of university campus data with 13 individual buildings showed that: (a) STLF with three aggregation strategies improves forecasting accuracy, compared with benchmarks without aggregation; (b) STLF-IA consistently presents superior behavior than STLF based on weather data and STLF based on individual load data; (c) MA reduces the occurrence of unsatisfactory single-algorithm STLF models, therefore enhancing the STLF robustness; (d) STLF-HA produces the most accurate forecasts in distinctive load pattern scenarios due to calendar effects.

"The structure of various stands, defined as the diversity of trees in the stands, can be an indication of overall biodiversity and habitat suitability, be useful in predicting stand growth and provide stand details for forest inventories. In an effort to find sustainable resource management strategies, a study was conducted on the structural and ecological characteristics of stands in Chettaba forest (Algeria). In this study, six diversity indices were used to characterize the horizontal and spatial distribution of individuals in multi-species stands, using four plots, located in the Chettaba forest (East-North Algeria). The results obtained allowed us to note that P2 and P3 present similar average densities (600 feet/ha), the plots P1 and P4 present low average densities (250 feet/ha and 350 feet/ha). The average DBH values vary from 25.65 cm for the P2 stand to 30.61 cm for the P1 stand. The average basal area varied between 33.73 m²/ha (P3) and 18.92 m²/ha (P1). The Shannon and Weaver index reached its maximum in plot 4 with 8 species. The study allowed us to evaluate the floristic diversity of the forest. Moreover, it indicated the need for its integral protection for its dynamics towards a dense forest vegetation."

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.

The forest industry is an important sector of the economy of many countries, because the timber grown in it can be used for achieving various economic goals, including increasing added value and exports. However, the social functions of forestry: rural employment and the availability of forests, in the form of various ecosystem services, are also important to the public. Forests are home to various protected species, and forest biotopes, biotopes associated with forests as well as the biodiversity of forests play an important role in preserving and improving the productivity, regeneration capacity and viability of the forests. Therefore, the Latvian Bioeconomy Strategy 2030 identifies forestry as one of the fields that needs development to achieve the goals of that strategy. Thus, the aim of the research is to study the Forestry section of the Latvian Bioeconomy Strategy 2030 strategic goal 5.2. �Result-orientated, efficient and sustainable resource management�. The research shows that as of the end of 2021, the Forestry objectives set in the Latvian Bioeconomy Strategy 2030 had only been accomplished partially. There is good progress in the replacement of non-productive areas of forest stand with productive stand; the use of planting material that is genetically improved and suitable for climate change in forest regeneration and afforestation; the thinning of young forest stand; the reconstruction and construction of forest amelioration systems; the range and intensity of the ecosystem services provided by commercial forests, as well as the achievement of the objectives for the preservation and renewal of biological diversity.

Abstract Operators face many challenges when selecting well-intervention candidates and evaluating a field’s potential because the process is highly time consuming, labor intensive, and susceptible to cognitive biases. An operator can lose up to USD 10 million/year because of ineffective well-intervention strategies in a single field. The objective of this study is to reduce such losses and standardize the well-intervention process by intelligently using the domain knowledge with artificial-intelligence (AI) and machine-learning (ML) techniques. The workflow developed in this study can automatically and autonomously analyze the surface-subsurface data to expeditiously recommend the top intervention candidates. The workflow leverages proven petroleum-engineering methods and customizable business logic to identify underperforming wells and then recommend workover techniques, post-workover production, success probability, and profitability. It uses production, petrophysics, reservoir, and economics data to run a series of AI/ML techniques. The data-analytics engine runs k-nearest neighbors to predict post-workover rates, followed by a decision tree to identify the remedies. Artificial neural network, random forest, and Monte-Carlo simulation are adapted to identify new perforation opportunities in existing wells. Analytic hierarchy process ranks the top intervention candidates based on post-workover rate, permeability, remaining reserves, and reservoir-production trends. Finally, Bayesian belief network calculates the probability of success. With this implementation, the manual benchmarking process of opportunity identification, which usually takes weeks to months, can now be completed within minutes. Once the opportunity is identified and reviewed, it gets registered in the opportunity tracker list for the final evaluation by the asset team. The results are displayed on web-based applications with customizable dashboards and can be integrated with any existing online/offline systems. Because the whole process is now automated and takes very little execution time, petroleum engineers can review the field’s performance on a daily basis. With more than 80% predictive accuracy and 90% time saving compared to the manual process, this workflow presents a step-change in the operator’s well-intervention management capacity. In this paper, the authors discuss the adaptations to the industry-standard AI/ML algorithms and the best practices to provide a faster, more accurate, and efficient well-intervention advisory system.

Streszczenie:
Native and restored plant communities are part of the foundation of park ecosystems and provide a natural context to cultural and historical events in parks throughout the Heartland Inventory and Monitoring Network (HTLN). Vegetation communities across the HTLN are primarily of three types: prairie, woodland, and forest. Park resource managers need an effective plant community monitoring protocol to guide the development and adaptation of management strategies for maintaining and/or restoring composition and structure of prairies, woodland, and forest communities. Our monitoring design attempts to balance the needs of managers for current information and the need for insight into the changes occurring in vegetation communities over time. This monitoring protocol consists of a protocol narrative (this document) and 18 standard operating procedures (SOPs) for monitoring plant communities in HTLN parks. The scientific objectives of HTLN plant community monitoring are to (1) describe the species composition, structure, and diversity of prairie, woodland, and forested communities; (2) determine temporal changes in the species composition, structure and diversity of prairie, woodland, and forested communities; and (3) determine the relationship between temporal and spatial changes and environmental variables, including specific management practices where possible. This protocol narrative describes the sampling design for plant communities, including the response design (data collection methods), spatial design (distribution of sampling sites within a park), and revisit design (timing and frequency of monitoring visits). Details can be found in the SOPs, which are listed in the Revision History section and available at the Integrated Resource Management Applications (IRMA) website (irma.nps.gov). Other aspects of the protocol summarized in the narrative include procedures for data management and reporting, personnel and operating requirements, and instructions for how to revise the protocol.

This report describes the potential vulnerability of specialty crops, field crops, forests, and animal agriculture to climate-driven environmental changes. Here, vulnerability is defined as a function of exposure to climate change effects, sensitivity to these effects, and adaptive capacity. The exposure of specific sectors of the agricultural and forestry industries varies across the region because the Southwest is climatically and topographically diverse. There is also variability in the sensitivity of different systems to the effects of climate change. Most significantly, there is potential within agricultural and forestry systems to adjust to climate-related effects either through inherent resilience or through conservative management practices. The purpose of this analysis is to describe regional vulnerabilities to climate change and adaptive actions that can be employed to maintain productivity of working lands in the coming decades.

Elaboration and implementation of investment programs for the development of modern universities, cooperation with the business sector, public investment aimed at modernization of the educational environment, implementation of grants, etc. can now be considered as structural components of investment activities of higher education institutions in the context of strategic planning. Therefore, the process of active reform of the educational sector of Ukraine and its integration into the European educational space require a review of approaches, methods and forms of management of education and educational institutions, in particular on investment policy.

Topicality of modeling information transparency is determined by the influence it has on the effectiveness of management decisions made by an economic entity in the context of uncertainty and information asymmetry. It has been found that information transparency is a poorly structured category which acts as a qualitative characteristic of information and at certain levels forms an additional spectrum of properties of the information that has been adequately perceived or processed. As a result of structuring knowledge about the factor environment, a fuzzy cognitive model of information transparency was constructed in the form of a weighted digraph. Structural analysis and scenario forecasting of optimal alternatives of the fuzzy cognitive model made it possible to evaluate the classes of factors, identify their limited relations, establish the centrality of the roles of information transparency and information and communication security in the system built and evaluate their importance when modeling the situation self-development. Information visibility, reliability and availability have been found to have the strongest impact on the system. Taking into account different initial weights of the key factors — information transparency and information and communication security — the study substantiates the strategic ways for economic entities to achieve their goals in the context of uncertainty and information asymmetry, which allows us to use this approach as a tool for strategic management in the information environment.

There is a large number of control systems proposed either by lighting manufacturers or motor manufacturers for shading systems. In addition there are many other solutions proposed by specific manufacturers of Building Management Systems (BMS) or manufacturers of components to be installed in luminaires and switches, as well as in the electric lighting architecture (transformers, gateways to the internet, sensors, etc.). For many consumers -i.e.-the installer, the facility manager, or the final user (building occupant) – this forms a complex and dynamic market environment with high frequent changes, every year or even every month or day. In this report we aim to provide some basic strategic information, showing the status of the supply at the time this report was written (2019-2021). Although the market develops very fast, there are principles of controls which are rather independent of the progress of technology.

Streszczenie:
Highly imperiled Oregon white oak ecosystems are a regional conservation priority of numerous organizations, including Oregon Metro, a regional government serving over one million people in the Portland area. Previously dominant systems in the Pacific Northwest, upland prairie and oak woodlands are now experiencing significant threat, with only 2% remaining in the Willamette Valley in small fragments (Hulse et al. 2002). These fragments are of high conservation value because of the rich biodiversity they support, including rare and endemic species, such as Delphinium leucophaeum (Oregon Department of Agriculture, 2020). Since 2010, Metro scientists and volunteers have collected phenology data on approximately 140 species of forbs and graminoids in regional oak prairie and woodlands. Phenology is the study of life-stage events in plants and animals, such as budbreak and senescence in flowering plants, and widely acknowledged as a sensitive indicator of environmental change (Parmesan 2007). Indeed, shifts in plant phenology have been observed over the last few decades as a result of climate change (Parmesan 2006). In oak systems, these changes have profound implications for plant community composition and diversity, as well as trophic interactions and general ecosystem function (Willis 2008). While the original intent of Metro’s phenology data-collection was to track long-term phenology trends, limitations in data collection methods have made such analysis difficult. Rather, these data are currently used to inform seasonal management decisions on Metro properties, such as when to collect seed for propagation and when to spray herbicide to control invasive species. Metro is now interested in fine-tuning their data-collection methods to better capture long-term phenology trends to guide future conservation strategies. Addressing the regional and global conservation issues of our time will require unprecedented collaboration. Phenology data collected on Metro properties is not only an important asset for Metro’s conservation plan, but holds potential to support broader research on a larger scale. As a leader in urban conservation, Metro is poised to make a meaningful scientific contribution by sharing phenology data with regional and national organizations. Data-sharing will benefit the common goal of conservation and create avenues for collaboration with other scientists and conservation practitioners (Rosemartin 2013). In order to support Metro’s ongoing conservation efforts in Oregon white oak systems, I have implemented a three-part master’s project. Part one of the project examines Metro’s previously collected phenology data, providing descriptive statistics and assessing the strengths and weaknesses of the methods by which the data were collected. Part two makes recommendations for improving future phenology data-collection methods, and includes recommendations for datasharing with regional and national organizations. Part three is a collection of scientific vouchers documenting key plant species in varying phases of phenology for Metro’s teaching herbarium. The purpose of these vouchers is to provide a visual tool for Metro staff and volunteers who rely on plant identification to carry out aspects of their job in plant conservation. Each component of this project addresses specific aspects of Metro’s conservation program, from day-to-day management concerns to long-term scientific inquiry.
