Climate-smart forestry is a sustainable forest management approach for increasing positive climate impacts on society. As climate-smart forestry is focusing on more sustainable solutions that are resource-efficient and circular, digitalization plays an important role in its implementation. The article aimed to validate an automatic workflow of processing 3D pointclouds to produce digital twins for every tree on large 1-ha sample plots using a GeoSLAM mobile LiDAR scanner and VirtSilv AI platform. Specific objectives were to test the efficiency of segmentation technique developed in the platform for individual trees from an initial cloud of 3D points observed in the field and to quantify the efficiency of digital twinning by comparing the automatically generated results of (DBH, H, and Volume) with traditional measurements. A number of 1399 trees were scanned with LiDAR to create digital twins and, for validation, were measured with traditional tools such as forest tape and vertex. The segmentation algorithm developed in the platform to extract individual 3D trees recorded an accuracy varying between 95 and 98%. This result was higher in accuracy than reported by other solutions. When compared to traditional measurements the bias for diameter at breast height (DBH) and height was not significant. Digital twinning offers a blockchain solution for digitalization, and AI platforms are able to provide technological advantage in preserving and restoring biodiversity with sustainable forest management.

Several concepts are at the basis of forest ecosystem management, but a relative consensus exists around the idea of a forest management approach that is based on natural disturbances and forest dynamics. This type of approach aims to reproduce the main attributes of natural landscapes in order to maintain ecosystems within their natural range of variability and avoid creating an environment to which species are not adapted. By comparing attributes associated with natural fire regimes and current forest management, we were able to identify four major differences for the black spruce forest of the Clay Belt. The maintenance of older forests, the spatial extent of cutover areas, the maintenance of residuals within cutovers and disturbance severity on soils are major issues that should be addressed. Silvicultural strategies that mitigate differences between natural and managed forests are briefly discussed.

This paper provides an overview of a project that synthesized available information on climate change for the southwest Yukon. This was done as a first step in a longer-term process of evaluating climate impacts, assessing risks to ecosystem and community values, and developing scenarios for adaptation. The overall intent of the work was to support informed forest management decision-making for the Champagne-Aishihik Traditional Territory (CATT) in the light of climate change. The objectives of this stage of the project were to: compile and improve access to existing baseline information needed to support informed management decisions in the face of climate change; to make this information available using several communication tools for various target audiences; and to create an opportunity for scientists, government; and local residents to share observations and concerns on climate change as related to the management of forest resources within the study region.

A mail survey was conducted of local residents of a forest-dependent region (Fraser Fort George Regional District, n=974), provincial (British Columbia, n=1208) and Canadian (n=1672) publics to compare their values for forests and preferences for forest management (overall response rate=45.2%). While the local public tended to place a significantly higher (p<0.05) emphasis on economic values and clearcutting practices relative to provincial and national publics, all publics held quite similar views on forest management overall. All publics support a multi-value/ecosystem management over a single-value/timber management approach to forest management, do not support maximisation of economic returns from timber regardless of the impacts and agree forest managers should be more responsive to local resident values than the values of more distant groups. Responses also reflected a lack of public confidence in government natural resource agencies. Results suggest residents from forest and non forest-dependent communities share similar forest values, that current forest management practices such as clearcutting do not reflect the values of local, provincial or national publics, and that forest managers should be especially responsive to the values of the local public when making forest management decisions. Key words: social values, forest policy, public participation, socially sustainable forest management

Recovery Times

Despite the widespread use and strong promotion of the sustainable forest management approach, there are still uncertainties about the actual contribution of current forest management practices to sustainability. We studied the problem of sustainable timber production in four tropical countries (Belize, Guyana, Suriname, and Trinidad and Tobago). Data assessed on experimental plots covering 10 km2 were used to compare management practices of four forest tenure types that commonly exist in the study countries: large scale concessions (LSC), private forests (PR), periodic block system forests (PBS), and community managed forests (CM). As an indicator of sustainable timber production, we calculated the recovery times expected under the initial condition of the stands and compared them with currently practiced cutting cycles. Three growth scenarios were simulated using diameter growth rates (1.6/2.7/4.5 mm year−1) from empirical data from studies in the region. Initial volumes were determined for all commercial trees as well as for commercial trees with a DBH-threshold ≥45 cm. Highest initial volumes were found in LSC and PBS managed forests. Lowest volumes were found in CM and PR forests. Assuming the lowest growth rate for all commercial trees, none of the stands studied reached the initial pre-harvest volumes within the currently practiced cutting cycles. Assuming the highest growth rate for all trees, LSC, PBS, and PR forests reach the initial pre-harvest volume. Looking at the subset of commercial trees with a DBH ≥45 cm, all stands will reach the initial volume within 30 years only if the highest growth rate is assumed. We show that general harvest codes do not guarantee sustainable forest management in the tropics. Local stand conditions must always be one of the guiding principles of sustainable timber utilization. Applying the rigid rules, which do not take into account the current conditions of the stands, entails long-term risk of forest degradation.

Abstract In support of climate action, a paradigm shift in environmental management needs to occur by acknowledging the perspective of traditional communities and customary law to preserve the environment. Efforts to anticipate and mitigate the impacts of climate change are important in sustainable development. Sustainability of forest management is highly dependent on the participation of local communities which enforce customary law in forest management. Reducing and preventing deforestation can accelerate efforts in mitigation and improving resilience. This paper aims to describe the contribution of customary law as an approach to sustainable forest management for supporting climate action. The research method uses a qualitative approach with literature study and document study. This study shows that customary law has contributed in sustainable forest management approach for the protection by integrating aspects based on ecological and social characteristics in forest ecosystem. In addition, the existence of indigenous people in the context of forest resource conservation is one of the important factors in the practice of just and sustainable management of conservation areas. The contribution of this research is by serving as a reflection and evaluation of forest management practices in order to integrate customary law in regulation and the formation of public discourse regarding awareness of environmental protection.

Riverside Forest Products (Kelowna, British Columbia) has embraced a sustainable forest management approach for the management of one its forest tenures—Tree Farm License 49. This document discusses the rationale behind many of the concepts within this approach in the context of current ecological theory. We focus specifically on the following concepts: (1) forest retention, (2) ecosystem representation, (3) ecological contributions from unharvested forests, (4) zoning and the TRIAD approach, (5) stand-level habitat elements and landscape-level features, and (6) ecological indicators. This document provides an example of the application of current ecological theory within a commercial forestry operation in Canada and is thus broadly applicable to foresters, forest managers, and researchers in most jurisdictions. Key words: British Columbia, criteria and indicators, ecological representation, forest retention, sustainable forest management, Riverside Forest Products, TRIAD

Natural disturbance emulation (NDE) has been proposed as a general approach to ecologically sustainable forest management. We reviewed the concepts, theories, and strategies related to NDE in boreal forest management. We also reviewed publications that discussed NDE in the boreal forest in general and those that specifically compared NDE-based management with conventional even-aged management. The papers generally focused on northern North America and landscape-scale wildfire as the main disturbance factor, whereas information from Eurasia was exclusively theoretical. Within this limited scope, NDE was generally found to have a positive effect on biodiversity in terms of forest structure and species diversity when compared with conventional even-aged management. Studies on timber supply and social implications of NDE were so few that they preclude generalizations. We conclude that the ecological and economic performance of NDE as a management approach still remains poorly examined. To advance the development of NDE, particular attention should be given to (1) augmenting the knowledge base on natural range of variability of unmanaged forest ecosystems and evaluating the validity of this information in a changing climate, (2) fostering multidisciplinary research with better integration of ecological theory to both integrative and analytical research on NDE, and (3) better integration of socioeconomic concerns, adaptive management schemes, and international collaboration into NDE initiatives.

The implementation of todays forest management that based on formal-scientific knowledge and technical knowledge seems to fail to protect the forest from deforestation and the environmental damage. Decolonialisation of western knowledge could give an opportunity to identify and find the knowledge and practices of indigenous people in sustainable forest management. Forest management based on the indigenous knowledge and practices is believed easy to be accepted by the indigenous community due to the knowledge and practice is known and ‘lived’ by them. The Atoni Pah Meto from West Timor has their own customary law in forest management that is knows as Bunuk. In the installation of Bunuk, there is a concencus among the community members to protect and preserve the forest through the vow to the supreme one, the ruler of the earth and the ancestors, thus, bunuk is becoming a le’u (sacred). Thus, the Atoni Meto will not break the bunuk due to the secredness. Adapting the bunuk to the modern forest management in the Atoni Meto areas could be one of the best options in protecting and preserving the forest.

The Impact

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.
