The development of technologies and equipment that meet modern requirements of forest preservation and a gentle mode of forest exploitation becomes a relevant issue within the framework of the implementation of the sustainable forest management principles both at forestry enterprises and in the organization of forestry. Such technologies include developed and field-tested experimental methods of logging using balloon-rope systems for various types and methods of felling. Of particular interest is the concept of using this equipment based on the purpose logging and the environmental and forestry requirements for their implementation. The paper has informative and cognitive nature; its purpose is to provide professionals with information on new technologies and designs of specialized equipment to ensure a gentle mode of forest management and forest exploitation. The article presents the results of theoretical research on possible directions of use of balloon-rope systems when working on forest sites of specially protected natural areas. The authors propose the designs of specialized equipment for the vertical removal of trees (whips) in the process of intermediate felling on the areas with signs of hard access and ecological dependence. Such mechanisms will significantly reduce energy costs when removing branches and limbs from a standing tree and its vertical removal from the plantation. The developed designs of specialized mechanisms for skidding a vertically standing tree without its landing in the form of a grabbing, grabbingcutting and knot-cutting device with a grabber ensure the maximum possible preservation of the forest environment, since they do not cause damage to the nearby stand, the undergrowth or the soil.

The sustainable practices of Forest Management activities are used with the objective of minimizing impacts to the environment, as well as exploring tree individuals with qualities that aim at the highest volumetric yield in sawmills. However, some characteristics may not be diagnosed before logging, as is the case with hollow trees, commonly found in forested areas. Thus, the objective was to diagnose the occurrence of hollow trees in two areas of forest exploitation, for the knowledge of individuals at the family and botanical species level. In order to carry out thediagnosis of the occurrence of hollow trees, data on the effective exploitation of trees in the Company's Forest Management areas were obtained through a collection of information on two Annual Production Units - UPA, named according to the company's specification as named as UPA ITP11 and UPA FLA01. In each UPA, tree individuals were identified by gender, species, family, distribution, presence of hollowness and the basic density of their wood.  The results show that in the UPA ITP11 area, 7.38% of the total trees explored, had hollowness, while in the UPA FLA01 area it was 4.88% and that the majority had high basic density. Twenty botanical families were identified in the exploration areas, where the Leguminosae family obtained the greatest representation. A total of 49 botanical species explored were identified, being Manilkara huberi (Ducke) Stanley, as basic high density wood. Regarding the frequency of occurrence of hollowness, the species Dinizia excelsa Ducke, popularly known as Angelim Vermelho, stood out for the two areas under study. However, it is shown the considerable existence of hollow trees among the trees selected for forest exploitation, reinforcing the importance of better targeting of appropriate methodologies for their identification, as well as, the better volumetric utilization of logs in sawmills, in order to certify the sustainability for the activity, regardless of the structural aspect of forestry individuals.

Abstract The implementation of goals of modern forestry requires a simultaneous consideration of sustainable development of forests, protection, needs of the environment development, as well as maintaining a balance between functions of forests. In the current multifunctional forest model, rational forest management assumes all of its tasks as equally important. Moreover, its effects are important factors in the nature and environment protection. The paper presents legal conditions related to the definitions of forest management concepts and sustainable forest management. Authors present a historical outline of human’s impact on the forest and its consequences for the environment. The selected aspects of forest management (eg. forest utilization, afforestation, tourism and recreation) and their role in the forest environment have been discussed.

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.

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.

Abstract Background National forest inventory and forest monitoring systems are more important than ever considering continued global degradation of trees and forests. These systems are especially important in a country like Bangladesh, which is characterised by a large population density, climate change vulnerability and dependence on natural resources. With the aim of supporting the Government’s actions towards sustainable forest management through reliable information, the Bangladesh Forest Inventory (BFI) was designed and implemented through three components: biophysical inventory, socio-economic survey and remote sensing-based land cover mapping. This article documents the approach undertaken by the Forest Department under the Ministry of Environment, Forests and Climate Change to establish the BFI as a multipurpose, efficient, accurate and replicable national forest assessment. The design, operationalization and some key results of the process are presented. Methods The BFI takes advantage of the latest and most well-accepted technological and methodological approaches. Importantly, it was designed through a collaborative process which drew from the experience and knowledge of multiple national and international entities. Overall, 1781 field plots were visited, 6400 households were surveyed, and a national land cover map for the year 2015 was produced. Innovative technological enhancements include a semi-automated segmentation approach for developing the wall-to-wall land cover map, an object-based national land characterisation system, consistent estimates between sample-based and mapped land cover areas, use of mobile apps for tree species identification and data collection, and use of differential global positioning system for referencing plot centres. Results Seven criteria, and multiple associated indicators, were developed for monitoring progress towards sustainable forest management goals, informing management decisions, and national and international reporting needs. A wide range of biophysical and socioeconomic data were collected, and in some cases integrated, for estimating the indicators. Conclusions The BFI is a new information source tool for helping guide Bangladesh towards a sustainable future. Reliable information on the status of tree and forest resources, as well as land use, empowers evidence-based decision making across multiple stakeholders and at different levels for protecting natural resources. The integrated socio-economic data collected provides information about the interactions between people and their tree and forest resources, and the valuation of ecosystem services. The BFI is designed to be a permanent assessment of these resources, and future data collection will enable monitoring of trends against the current baseline. However, additional institutional support as well as continuation of collaboration among national partners is crucial for sustaining the BFI process in future.
