In this paper, we provide an overview of a project that we initiated to explore the utility of spatially-explicit metapopulation models linked to dynamic landscape models as a way of incorporating biological indicators into sustainable forest management. We developed models for three indicator species as case studies; brown creeper (Certhis americana), redbacked vole (Clethrionomys gapperi) and red-backed salamander (Plethodon cinereus) in a northern Ontario landscape. Results from the project to date suggest that there are significant advantages to models that are spatially-explicit and dynamic in their treatment of both populations and landscapes. Dynamic landscape metapopulation (DLMP) models allow a manager to track population change through time in response to a changing landscape and a fluctuating environment. These DLMP models may be used to predict the impact of current and alternative forest management strategies on population sizes of a suite of species chosen to indicate the health of forest ecosystems. Key words: biological indicators, population viability analysis, population modeling, dynamic landscape modeling, sustainable forest management, brown creeper, red-backed salamander, red-backed vole

Are there any common patterns in the transition processes from traditional and more or less sustainable forest management to exploitative use, which can regularly be observed both in central Europe and in the countries of the South (e.g. India or Indonesia)? Attempts were made with a time-space-model to typify those force fields, in which traditional sustainable forest management is undermined and is then transformed into a modern type of sustainable forest management. Although it is unlikely that the history of the North will become the future of the South, the glimpse into the northern past offers a useful starting point for the understanding of the current situation in the South, which in turn could stimulate the debate on development. For instance, the patterns which stand behind the conflicts on forest use in the Himalayas are very similar to the conflicts in the Alps. In the same way, the impact of socio-economic changes on the environment – key word ‹globalisation› – is often much the same. To recognize comparable patterns can be very valuable because it can act as a stimulant for the search of political, legal and technical solutions adapted to a specific situation. For the global community the realization of the way political-economic alliances work at the head of the ‹globalisationwave›can only signify to carry on trying to find a common language and understanding at the negotiation tables. On the lee side of the destructive breaker it is necessary to conserve and care for what survived. As it was the case in Switzerland these forest islands could once become the germination points for the genesis of a cultural landscape, where close-to-nature managed forests will constitute an essential element.

Riau Province as one of the provinces in Indonesia with quite complex environmental problems, especially the problem of forest destruction and peat ecosystems, the impact of which is one of the largest contributors to the forest and land fire disaster that occurred in Indonesia. Forest and land fires continue every year, but law enforcement against perpetrators of forest and land fires. Law enforcement against perpetrators of forest and land burning is very important considering that one of the causes of forest and land destruction is the occurrence of fires or burning of forests and land before the use of the forest and land. This is important considering that one of the requirements for realizing Sustainable Forest Management (SFM) really depends on the conditions of policies, laws and institutions, all of which are included in Good Forestry Governance. The main cause of poor forest management is the failure of policies, laws and institutions. Weak forestry institutions cannot enforce laws and regulations related to forestry. Abstrak Provinsi Riau sebagai salah satu provinsi di Indonesia dengan persoalan lingkungan hidup yang cukup kompleks, khususnya persoalan kerusakan hutan dan ekosistem gambut yang dampaknya sebagai salah satu provinsi penyumbang terbesar bencana kebakaran hutan dan lahan yang terjadi di Indonesia. Kebakaran hutan dan lahan setiap tahun terus saja terjadi, namun penegakan hukum terhadap pelaku pembakaran hutan dan lahan. Penegakan hukum terhadap pelaku pembakaran hutan dan lahan menjadi hal yang sangat penting mengingat salah satu penyebab kerusakan hutan dan lahan adalah terjadinya kebakaran atau dibakarnya hutan dan lahan sebelum hutan dan lahan tersebut digunakan. Hal ini menjadi penting mengingat salah satu syarat mewujudkan Sustainable Forest Management (SFM) sangat tergantung pada kondisi kebijakan, hukum dan institusi, yang semuanya itu tercakup dalam Good Forestry Governance. Penyebab utama manajemen hutan yang buruk adalah tidak berjalannya kebijakan, hukum dan kelembagaan. Lembaga kehutanan yang lemah tidak bisa menegakkan hukum dan peraturan perundang-undangan terkait kehutanan.

The objective of the study was to examine the impact of the COVID-19 pandemic on sustainable forest management in southern Africa. The study employed a targeted approach, also referred to as purposive sampling, to select respondents from the various sectors. The results show that COVID-19 had an 80% impact on forest management operations. The COVID-19 pandemic did not have a significant effect on the conversion of land from forest to other land uses. However, there was severe illegal logging and moderate to severe fires. The COVID-19 pandemic also had a severe impact on the agriculture, environment and ecotourism sectors, with nature reserves completely closed. From the forest production perspective, the impact of COVID-19 on production, supply, demand and the price of timber was generally low due to the commercial nature of the forestry sector in South Africa; the largest economy in SADC being classified as an essential sector.

Participatory forest management has been considered as a practical and effective strategy for sustainable forest management, especially in situations where land tenure is not securely settled. For effective forest restoration, local communities, as the cornerstone of participatory management, should be provided with incentives to facilitate their participation and active role. We postulate that participation in mangrove restoration projects can not only provide financial rewards but also yield intangible benefits for communities, i.e., social capital. The study was conducted in the province of Quezon, Philippines, using face-to-face interviews as the main method for data collection. Regression analyses were undertaken to assess the impact of local community participation in mangrove restoration projects on social capital and its potential benefits to people in terms of access to information and services, which are key components of livelihood. Results revealed that people’s participation in mangrove restoration projects contributes to increasing social capital, consequently improving their access to information and services. Local people’s participation is beneficial to communities, as it can improve their livelihoods.

This research note presents the results of a bibliometric analysis that was conducted to better understand the impact that Sustainable Forest Management Network (SFMN) funded research had in the forest-related social and Aboriginal research communities. We applied two indicators of research impact: (i) research outputs and (ii) citations. Our results suggest that the SFMN’s research outputs were highest in the fields of economics, sociology, and political science and law. The number of research articles that acknowledged the SFMN was 30% of the total research output of the SFMN-funded Principal Investigators. These articles represented 3% of the social science articles published in the Forestry Chronicle (the journal most frequently used by SFMN-funded Principal Investigators). Research output related to Aboriginal forestry indicated that the SFMN had a significant influence on the development of the field. Our citation analysis indicated that the average number of citations per SFMN-acknowledged publication in the social sciences was approximately the same as the international impact standard in the field. These results suggest that the SFMN-funded research in the social sciences compared very well with the international research standards in forest-related social sciences.

Part of a recently advocated method of sustainable forest development employs indicator species as fine filters to assess changes within ecosystems and landscapes. We used a series of criteria based on biology, sampling methods, and legal or particular status to select vertebrate indicator species for the province of Ontario. The criteria for selection were applied in a hierarchical manner, with species ecology given primary importance, followed by sampling considerations, and status criteria. The latter represented certain societal weightings and political or featured management concerns. Species fitting the selection criteria were placed in a four-dimensional matrix (with axes: broad habitat type, age class, trophic level, and spatial scale), and species were then chosen from among the matrix cells. The exercise reduced the total vertebrate species in two forest biomes (Boreal and Great-Lakes St. Lawrence) to a relative few, from which the final choices were made primarily based on expert opinion. In Ontario, the species selected as indicators of biological diversity will be used to test the underlying general hypothesis that forest management has no effect on species richness and species abundance, or the distribution of species in time and space.

Aim of study: Modelling of forest growth and dynamics has focused mainly on pure stands. Mixed-forest management lacks systematic procedures to forecast the impact of silvicultural actions. The main objective of the present work is to review current knowledge and forest model developments that can be applied to mixed forests.Material and methods: Primary research literature was reviewed to determine the state of the art for modelling tree species mixtures, focusing mainly on temperate forests.Main results: The essential principles for predicting stand growth in mixed forests were identified. Forest model applicability in mixtures was analysed. Input data, main model components, output and viewers were presented. Finally, model evaluation procedures and some of the main model platforms were described.Research highlights: Responses to environmental changes and management activities in mixed forests can differ from pure stands. For greater insight into mixed-forest dynamics and ecology, forest scientists and practitioners need new theoretical frameworks, different approaches and innovative solutions for sustainable forest management in the context of environmental and social changes.Keywords: dynamics, ecology, growth, yield, empirical, classification.

Elements  of the modern day vision on sustainable forest management are discussed. Some  aspects of the concept are analysed, focusing on the natural definition in  comparison with the ecosystem definition. The significance of ecological  stability is emphasized. It is pointed out that perhaps the most important  aspect of forest stability and sustainability is the ability to retain soil  fertility. Attention is paid to the importance of species composition, the  role of organic matter, the impact of forest use and the problems of forest  engineering.     In order to reach sustainable forest management, a number of strategies can  be applied, based either on the market or the state. There is a need for  measurable criteria and indicators for the evaluation of sustainability.  Therefore new programmes of scientific sampling or even basic research are  still needed.     Forest sustainability provides still a dramatic lot of questions and  efforts, a.o. on the potentiality of sustainable forestry.

Forest benefit analysis is vital in ensuring sustainable community-based natural resources management. Forest depletion and degradation are key issues in rural Zimbabwe and strategies to enhance sustainable forest management are continually sought. This study was carried out to assess the impact of forests on communities from Nyanga, Guruve and Zvimba districts of Zimbabwe. It is based on a Big Lottery Fund project implemented by Progressio-UK and Environment Africa. Itfocuses on identifying replicable community forest and landmanagement strategies and the level of benefits accruing to the community. Analysis of change was based on the Income and Food Security and Forest benefits, which also constitutes the tools used during the research. The study confirms the high rate of deforestation and the increased realisation by communities to initiate practical measures aimed at protecting and sustaining forest and land resources from which they derive economic and social benefits. The results highlight the value of community structures (Farmer Field Schools and Environmental Action Groups) as conduits for natural resource management. The interconnectivity among forests, agricultural systems and the integral role of people are recognised as key to climate change adaptation.Keywords: Forest benefits; sustainability,;livelihoods; farmer field schools
