In Lampung Province, awareness of the importance of forest health in achieving sustainable forest management in various types of forests is still low so that forest health problems have not received serious attention so far. This study aims to obtain indicators of forest health assessment and the status of forest health conditions in various types of forests in Lampung Province. This research was carried out in mangrove and community forests in East Lampung District, and protected and conservation forests in Tanggamus District in 2018. The stages of this study consisted of formulating guarantees of forest health indicators, making measuring plots, measuring forest health, processing data, and forest health assessment. The results showed that indicators for assessing the health of forests in mangrove forests are vitality and biodiversity, in community forests are productivity, vitality and site quality, in protected forests are biodiversity, vitality and productivity, and in conservation forests are biodiversity and productivity. The status of health conditions in each cluster of plots in mangrove forest is bad and good, in community forests is good and medium, in protected forests is bad and good, and in conservation forests are bad and good.Keywords: indicator, forest health status, forest types, Lampung Province

This study measured the effects of joint forest management (JFM) on forest conditions in purposively selected three forest divisions of Khyber Pakhtunkhwa, Pakistan. The technique of experimental (JFM) versus control (non-JFM) group was applied. Assessment was made between JFM forest and nearby similar non-JFM forest located in the same forest-ecological and socio-economic settings. A total of 393 sample plots (234 from JFM forests while 159 from non-JFM forests) were assessed. Results of independent sample t-test revealed significant difference between JFM and non-JFM forests. Average tree density of JFM forests was 276 trees/ha while for non-JFM forests it was 247 trees/ha. Similarly average seedlings density/ha in JFM forests was 3114 as compared to 1987 in non-JFM forests. Data analysis explored that human disturbances were more in non-JFM forests as compared to JFM forests where joint forest management committees played active role in their protection. In JFM forests, forest protection and improvement activities were observed more times as compared to non-JFM forests. So, this can be concluded that JFM has remarkable contribution in protection and improvement of forests in study areas. It is recommended that network of JFMCs should be extended to non-JFM forests for protecting them from further degradation.

Optimization of primary forest accessibility is observed from the point of intensity of forest management and terrain relief conditions of the forest area. Optimization of primary forest accessibility is the first phase of the planning of primary forest traffic infrastructure. The second phase is designing of new primary forest traffic infrastructure. The high forests with natural regeneration (high forests) in the public forests are selected for optimization of accessibility because they are the most valuable forest category from the point of quantity and quality of timber. Planning of primary forest traffic infrastructure implies analysis of actual primary forest accessibility of high forests, determination of optimal density of primary forest traffic infrastructure, defining of suitability of high forests area for construction of primary forest traffic infrastructure and upgrading of actual primary forest traffic infrastructure with new routes of primary forest traffic infrastructure. Optimization of primary forest accessibility in hilly and mountainous high forests was done in two Management Units, Prosara and Bobija-Ribnik. Optimal density of primary forest traffic infrastructure ranges from 24 to 26 m/ha. Results showed that high forests have potential for sustainable forest management.

Streszczenie:
There is an increasing interest in community-based forest management as a potential approach for improving forest governance. India is among the few countries in the world where such an approach-called Joint Forest Management (JFM)-has not only been successfully introduced but also achieved large-scale implementation, covering 18% of all state forests. Forests cover 23% of India's geographical area and almost all are under state ownership. However, over half the forests are in a degraded condition. Forests also provide livelihood support to a large proportion of the population, especially the poor. Around 147 million people live in and around forests. But until the 1980s, the focus was on commercial forestry and people were excluded from forest management. This led to forest degradation on the one hand, and conflicts between the Forest Department and local communities on the other. A new policy in 1988 stressed forest management for ecosystem services and meeting local communities’ needs. Under this policy, Joint Forest Management promoted agreements between the Forest Department and village communities to jointly protect and manage adjacent forest land and to share responsibilities and benefits. JFM has had several positive impacts on forest governance in the form of improved forest condition, increased income and livelihood opportunities for participating communities and, most importantly, a dramatic change in the attitude of communities and the Forest Department towards each other and toward forests. Although challenges still remain, if implemented in its true spirit, JFM can be a viable long-term strategy for contributing towards the goals of sustainable livelihoods and forest management.

The objective of the study reported here was to compare voivodships in terms of forest area, forest regeneration area, afforested area, thinned forest area and natural forest regeneration area Main Statistical Office data for Polish voivodships was analysed. It included forest area, natural forest regeneration and silviculture activities (forest regeneration, afforestations and thinning) in all forests, state-owned forests and privately-owned forests. Voivodships were compared using the arithmetic mean, the indicator of structure, the average rate of change, principal component analysis and cluster analysis. Principal Component Analysis, revealed that state-owned forest area, forest regeneration in state forests, total forest regeneration, and thinning in state-owned forests had the greatest share in the multivariate variation among voivodships analysed in terms of forestry. Cluster analysis yielded two groups of voivodships. The voivodships in the first group had a higher average total forest area, area of state-owned forests, total area of forest regeneration and forest regeneration in state-owned forests, area of natural forest regeneration and thinning in state-owned forests. On average, forests of voivodships which formed group 2 included less privately-owned forests in which fewer forest regeneration and afforestation activities had been conducted. Opolskie and Śląskie Voivodships as well as Łódzkie and Świętokrzyskie Voivodships were the most similar in terms of all the analysed characteristics.

Streszczenie:
We introduce a new spatially explicit model of forest dynamics. The model is constructed from submodels that predict an individual tree's growth, survival, dispersal, and recruitment, and submodels that predict the local availability of resources. Competition is entirely mechanistic; plants interfere with one another only by depleting resources. We also describe maximum likelihood methods for estimating each of the submodels from data collected in the field. Over the past two years, we collected the necessary data for the dominant tree species in the Great Mountain Forest (Norfolk, Conn.). We report estimates of submodels for each species, and show that the calibrated population dynamic model predicts the structure and dynamics of natural forests. Finally, we contrast our model with the JABOWA–FORET family of forest models.

Forests play a key role in the regional or global carbon cycle. Determining the forest carbon budget is of great significance for estimating regional carbon budgets and formulating forest management policies to cope with climate change. However, the carbon budget of Chinese different forests and their relative contributions are not completely clear so far. We evaluated the carbon budget of different forests from 1981 to 2020 in China through combining model with remote sensing observation. In addition, we also determined the relative contribution of carbon budget of each forest type to all forests in China. Eight forest types were studied: evergreen coniferous forest (ECF), deciduous coniferous forest (DCF), coniferous and broad-leaved mixed forest (CBF), deciduous broad-leaved forest (DBF), evergreen broad-leaved forest (EBF), evergreen deciduous broad-leaved mixed forest (EDBF), seasonal rain forest (SRF), and rain forest (RF). The results indicated that the Chinese forests were mainly carbon sink from 1981 to 2020, particularly the annual average carbon budget of forest from 2011 to 2020 was 0.191 PgC·a-1. Spatially, the forests’ carbon budget demonstrated obvious regional differences, gradually decreasing from Southeast China to Northwest China. The relative contributions of carbon budget in different forests to all forests in China were different. During 2011–2020, the ECF forests contributed the most carbon budget (34.45%), followed by DBF forests (25.89%), EBF forests (24.82%), EDBF forests (13.10%), RF forests (2.23%), SRF forests (3.14%) and CBF forests (1.14%). However, the DCF forests were found mainly as carbon source. These results contribute to our understanding of regional carbon budget of forests.

Streszczenie:
Finnish forestry and forest science reflect demands set by the state administration and the forest industry but also private forest and nature conservation organisations, and nowadays private citizens e.g., through social media. From the late nineteenth century to the 2020s, the history of forests, forest science and Finnish society consists of four main periods. During the first period – know the forests (late nineteenth century–1930s) – society needed and gained information on forests, especially on growing timber stock (the first forest inventory in the 1920s) and wood consumption (the first inventory of wood consumption in the 1930s). In addition, researchers produced knowledge for silvicultural practices and forest biology. Rationalising forestry and developing timber procurement were seen as essential during the second period – exploit the forests (1940s–1960s). Since timber removals exceeded annual growth, the state launched massive forest improvement actions. Large clear-cuttings were regenerated with conifer saplings and massive draining of bogs was enacted. As a result, society more extensively exploited and influenced the forests. During the third period – define the forests (1970s–1990s) –forests were no longer respected merely as a source of economic prosperity. Escalating disputes came about when environmental activism and public discussions challenged forestry practices. Scientific knowledge became imbricated, besides traditional forestry values, also with nature conservation, recreational and environmental values related to forests. During the 1990s, changes in forest legislation paved the way for more pluralistic values of forests. During the most recent period – discover forests’ futures (2000s–) – climate change and conflicting human-forest relationships set new demands for forestry and forest science. Forests’ importance has grown from the private and national level to the global context. Forests are respected as carbon sinks and storage, for their rich biodiversity, and as a source of mental and physical health. Forests as living entities are often recognised and new steps have been taken towards more pluralistic human-forest relationships, posthumanism and interspecies perspectives.

AbstractThere is a long-standing, even ancient, belief in Western thought that forests, particularly unmanaged forests relatively free from obvious human impacts, are never-changing; this is the connotation of the German word “urwald” or “original forest” that influenced early thinking on forests from the origins of the emerging scientific disciplines of forestry and ecology in the 1800s. However, all forests, including extant ancient forests, are in fact in a state of flux.

AbstractForests mainly consist of long-lived trees or shrub species and are exposed to natural or human disturbances of different severities. They are essential components of the natural development of forest ecosystems, since by triggering natural selection and ecological succession processes, they can achieve the best status in terms of species composition and structure. Nevertheless, extreme events can cause serious economic or naturalistic losses and, in some cases, endanger specific forest ecosystems. Disturbance events that damage forests vary and include pests and diseases, fires, pollution, climate changes, overexploitation or inadequate silvicultural practices, excessive grazing and browsing, to name just a few. Health monitoring of forests is a necessary condition to provide useful information for the conservation of forest resources, as well as to support forest management practices aimed at increasing the resilience of forests and their adaptation capacity. Through ground surveys, the Italian national forest inventory INFC has classified the health condition of Italian forests and produced the estimates presented in the chapter. These concern the distribution of the Forest area by pathologies and damage presence, severity and cause. Estimates of the Forest area affected by defoliation, divided by defoliation class and localization of defoliation, are also presented.

AbstractIn Spain, 55% of land area is covered by forests and other woodlands. Broadleaves occupy a predominant position (56%), followed by conifers (37%) and mixed stands (7%). Forest are distributed among the Atlantic (north-western Iberian rim), Mediterranean (rest of the peninsula including the Balearic Islands) and Macaronesian (Canary Islands) climate zones. Spanish woodlands provide a multiplicity of provisioning ecosystem services, such as, wood, cork, pine nuts, mushrooms and truffles. In terms of habitat services, biodiversity is highly relevant. Cultural services are mainly recreational and tourism, the latter being a crucial economic sector in Spain (including rural and ecotourism). Regulatory services, such as erosion control, water availability, flood and wildfire risk reduction, are of such great importance that related forest zoning and consequent legislation were established already in the eighteenth century. Climate change in Southern Europe is forecast to involve an increase in temperature, reduction in precipitation and increase in aridity. As a result, the risks for natural disturbances are expected to increase. Of these, forest fires usually have the greatest impact on ecosystems in Spain. In 2010–2019, the average annual forest surface area affected by fire was 95,065 ha. The combination of extreme climatic conditions (drought, wind) and the large proportion of unmanaged forests presents a big challenge for the future. Erosion is another relevant risk. In the case of fire, mitigation strategies should combine modification of the land use at the landscape level, in order to generate mosaics that will create barriers to the spread of large fires, along with stand-level prevention measures to either slow the spread of surface fires or, more importantly, impede the possibility of fire crowning or disrupt its spread. Similarly, forest management can play a major role in mitigating the impact of drought on a forest. According to the land use, land-use change and forestry (LULUCF) accounting, Spanish forests absorbed 11% of the total greenhouse gas emissions in 2019. Investments in climate-smart forestry provide opportunities for using all the different parts of the Spanish forest-based sector for climate mitigation––forest sinks, the substitution of wood raw materials and products for fossil materials, and the storage of carbon in wood products. Moreover, this approach simultaneously helps to advance the adaptation of the forest to changing climate and to build forest resilience.

AbstractFinland is the most forested country in the EU – forests cover 74–86% of the land area, depending on the definition and source. Increasing carbon sequestration from the atmosphere, and by storing it in forests (trees and soil) will be one important part of the Finnish climate smart forestry strategy. However, just maximizing the carbon storage of forests may not be the best option in the long run, although it may provide the best climate-cooling benefits in the short term. This is because the increasing risks of large-scale natural disturbances may turn forests, at least partially, into carbon sources. The climate change adaptation and mitigation should therefore be considered simultaneously. Different adaptation and risk management actions will be needed in Finnish forests in the coming decades to increase forest resilience to multiple damage risks. This could be done, for example, by increasing the share of mixtures of conifers and broadleaves forests instead of monocultures. Yet, the CSF strategy should also include the production of wood-based products that act as long-term carbon storage and/or substitute for more GHG-emission-intensive materials and energy. Doing this in a way which also enhances biodiversity and sustainable provisioning of multiple ecosystem services, is a key. Moreover, increasing forest land – for example, by planting on abandoned or low-productivity agricultural land, especially on soils with a high peat content – would enhance climate change mitigation.

AbstractThe climate-smart forestry approach was pioneered in 2015 and has been generating increasing interest since then. It was developed as a response to the often very narrow and partial perspective on how forests and the forest-based sector can contribute to climate-change mitigation. Moreover, its basis is the understanding that, in order to effectively enhance climate mitigation, efforts should be made to find synergies and minimise trade-offs with the other ecosystem services forests provide, such as biodiversity, wood production and recreation. By doing this, greater support can be generated for climate mitigation measures. The approach acknowledges that there is no one-size-fits-all toolkit to cover all circumstances, but rather measures have to be tailored according to regional characteristics and institutions. In summary, climate-smart forestry is a holistic approach to how forests and the forest-based sector can contribute to climate-change mitigation that considers the need to adapt to climate change, while taking into account specific regional settings.

Streszczenie:
Effective forest management is required to reduce deforestation, protect local communities, tackle climate change, and restore biodiversity. Like other countries in sub-Saharan Africa (SSA), Nigerian federal and decentralised governments have to find a balance between managing their forests sustainably, and other demands for the trees and land. Local actors use the forest for economic activities, such as harvesting trees for charcoal or timber, and others want to expand agricultural land. No single policy solution can guarantee to sustainably manage forests and halt deforestation. Land use regulations, stronger control of forestry industry practices, more public investment in forest management, and better tax and subsidy policies, must all play a role. This paper assesses the current forestry tax regime in Ekiti State, one of eight Nigerian states where forests represent more than 50 per cent of land area, and where forest revenue has been historically relevant. Based on 16 interviews with government state officials, forest officers, and actors from the industry, and data from the Ekiti Forestry Commission, our analysis suggests that ongoing depletion of forest resources is partially connected to an excessive focus on their capacity to generate revenue. The conceptualisation of the Forestry Commission as a revenue-raising rather than management agency, a continuous drive to extract revenue from the sector through outdated tax rates, and a view of industry potential disconnected from the existing stock, all perversely led to a lower contribution from forestry to the state budget.

Forests are important socio-economic assets in many low-income countries. However, they are often over-exploited as governments do not sufficiently valorise them, including by taxing them inefficiently. This is the case across Nigeria, where forest management and taxation has been effectively decentralised from the federal government to individual states. In this paper we assess the current forestry tax regime in Ekiti State, one of the eight Nigerian states where forests represent more than 50 per cent of land area, and where forest revenue has been historically relevant. Based on 16 interviews with government state officials, forest officers and actors from the industry, as well as data from the Forestry Commission, our analysis suggests that the ongoing depletion of forest resources in the state seems to be partially connected to an excessive focus on their capacity to generate revenue. The conceptualisation of the Ekiti State Forestry Commission as a revenue-raising agency rather than a management one, a continuous drive to extract revenue from the sector through outdated tax rates, and a view of the industry potential disconnected from the existing stock, all perversely led to a lower contribution from forestry to the state budget. While there is potential to reform both the structure of forestry taxes and their method of administration, evidence from our interviews suggests that priority should be given to enforcing a ban on forest exploitation for a period that is long enough to allow for its regrowth, at least in government reserves. This will require substantial sensitisation and engagement with actors in the sector, as well as increasing the monitoring capacity of the Forestry Commission. The Forestry Commission does not currently have enough staff to guarantee the enforcement of existing legislation, let alone a ban on all forest activities.

The purpose of this report is to situate existing knowledge on First Nation-held forestry tenures and community forest enterprises (CFEs) in British Columbia, Canada within a broader discussion about Indigenous and non-Indigenous community forests in Canada. This report provides 1) A brief characterization of Indigenous forestry partnerships across Canada; 2) A description of the two most common First Nation-held forest tenures within British Columbia: the First Nations Woodland License and the community forest agreement; 3) An assessment of challenges and constraints facing First Nation-led CFEs in British Columbia; 4) An assessment of key enabling conditions in First Nation-led CFEs in British Columbia; and 5) Recommendations to enable Indigenous communities, policymakers, the private sector, and supporting institutions to strengthen the business proposition of Indigenous-led CFEs in British Columbia and elsewhere in Canada.

Timar, Levente. Modelling private land-use decisions affecting forest cover: the effect of land tenure and environmental policy. Motu Economic and Public Policy Research, listopad 2022. http://dx.doi.org/10.29310/wp.2022.12.

Streszczenie:
I use geographic data and discrete choice modelling to investigate private land-use decisions in the context of prominent New Zealand land institutions and environmental policies. Land-use conversions involving gains and losses in planted forests and natural forests are modelled individually. Land under Māori freehold tenure is found to be less likely to be used for pastoral grazing and also less likely to undergo land-use conversion (both to and from a forested use). With respect to environmental policies, results suggest the incentives of the Emissions Trading Scheme did not significantly affect land-use decisions during the sample period of 2008-2016: the carbon reward had little effect on afforestation, and the deforestation liability was largely ineffective at deterring deforestation. On the other hand, the East Coast Forestry Project is found to have increased planted forest area in the district both by encouraging afforestation beyond baseline levels and by discouraging deforestation. Evidence for its effect on regenerating natural forest area is weaker in the data.

Streszczenie:
Just over a decade ago, several forest agency leaders from around the world met in Beijing, China at a conference convened by the Rights and Resources Initiative (RRI), the State Forestry Administration (SFA) of China and the Chinese Center for Agriculture Policy (CCAP). As leaders—from Brazil, China, Mexico and the USA—we reflected on how few opportunities existed to learn from one another to discuss forest issues in an informal atmosphere outside of the protocol-laden, jurisdictionally-defined sessions we commonly attended. We wondered whether there was a better way—whether it was possible to have safe conversations where difficult issues, struggles and mistakes could be raised, acknowledged and learned from. From this first conversation, MegaFlorestais was created: a self-governing group of public forest agency leaders with RRI serving as the Secretariat and main funder. The period of 2005-2015 brought changes in forest governance, the status of forest ownership, the health of the world’s forests and the global context within which forestry decisions are made. But much has remained the same. Was MegaFlorestais a factor? What can be learned from reflecting on these changes in a decade?

Streszczenie:
This study challenges the current design of forest resource use contracts in Latin America. Radical rethinking of forest resource contracts is imperative, due to the constraints that now face the successful achievement of forest policy objectives of economic development and conservation of forest resources. The constraints identified in this study include: 1) financial incentives that favor selective logging rather than management in tropical forests; 2) lack of a technical basis for silviculture in neo-tropical forests; 3) governments that lack the administrative capacity and political will to impose management; 4) cultural and social norms that fail to recognize local users of forest resources. This study is intended to serve as a turning point in forest concession policy and provide useful guidelines for policy analysts, non-governmental organizations, and multilateral lending institutions interested in facilitating this process. A comprehensive rethinking of forest resource contracts will greatly benefit all those relying on the economic development and conservation of forests in Latin America.

Streszczenie:
Sweden’s Environmental Quality Objectives (EQOs) have been adopted to help describe the environment the country wishes to achieve, and are a promise to future generations of clean air, a healthy living environment, and rich opportunities to enjoy nature. Here, we assessed selected socio-economic indicators adapted from the Montréal Process for the Conservation and Sustainable Management of Temperate and Boreal Forests (MP) to examine trends in the Swedish forest sector of direct relevance to the EQOs. We did this with the aim of raising awareness about important socio-economic dimensions related to the EQOs, and to explore the linkages between the EQOs and the forest bioeconomy. We focused on the forest sector because of its central importance to meeting the EQOs, and fundamental social and economic roles it plays in Swedish society. The MP was chosen as our guiding framework because it was developed to assess national-level sustainable forest conservation and management, thus, incorporating critical economic, environmental and social dimensions. We applied a mixed methods approach based on a literature review, analyses of national and multilateral databases, and consultation with experts to identify and interpret selected indicators. We identified forest sector socio-economic indicators relevant to the EQOs related to forest property and ownership, economic value and consumption of wood and wood products, employment, wood energy, access to greenery, per capita forest availability, and cultural values. Interpretation of national-level indicators estimated for the 2000-2020 period point to overall progress toward maintaining forest conservation and production areas and a sector that has added substantial economic value through the processing of wood and wood products. Forests are an importance source of renewable energy and increasingly support the location of non-wood energy sources through the placement of wind power mills across forested lands. Downward trends were observed in fewer forest owners, a shrinking workforce, and per capita forest area which might be explained by processes of bequeathing, higher industry efficiencies and continued population growth. Selected indicators related to production forests, wood energy, per capita protected forests and cultural importance suggest these can directly support relevant EQOs including living forests, limited climate impact, rich plant and animal life. Through exports and hiring foreign workers, the Swedish forest sector has kept a direct linkage with the consumption of wood products abroad and in supporting economic wellbeing in lesser-developed nations through wages from forestry and non-wood seasonal employment, respectively. There is limited current information on cultural aspects such as heritage values and reindeer herding. Available data suggest a declining trend in damages to cultural remains within forest felling areas. We recommend regular and periodic assessment of the cultural and conservation values for Swedish forests to strengthen the ability to assess social and ecological sustainability relevant to the EQOs.

Streszczenie:
This paper addresses forest policies concerned with the adequate provision of forest related externalities. Despite the use of the forest vocation land (FVL) in the legislation of many Latin American countries, the discussion in the scientific literature about forest policies based on it is modest. This paper seeks to contribute to this debate. The paper presents facts, defines concepts, examines analytical frameworks, and investigates policy alternatives related to these externalities in private lands. The paper concludes that FVL is a useful model for the design of forest policies that seek to assure the provision of forest related externalities. Such policies are: especially adequate for developing countries because they are relatively easy to understand; are less intrusive in the forest business decision making processes and, thereby, allow for greater freedom of action; are less costly to monitor, enforce, and comply with; reduce corruptive activities and illegality associated with forests; and do not require adjustments as technologies and market conditions change.
