The Ideal

Determining the ideal sampling intensity is important to guarantee data closer to reality with less cost and time in the forest inventory. The objective of this paper was to evaluate the influence of different sample intensities to estimate the floristic composition, species diversity and the timber volume, beyond compare the results with their respective parameters obtained in the census of an ombrophilous open forest area in Verde Para Sempre Extractive Reserve. Was simulated a random sampling with sampling units of 1 ha and several sample intensities: 5%, 10%, 15% and 20% in an area of 200 ha that it was submitted to a forest census. It was evaluated the phytosociological parameters such as structure and diversity, and the estimated errors in the sampling intensities for the volume. The forest has a structure with high diversity and species of high economic value, indicating the existence of an aptitude for sustainable forest management. The treatment with 5% and 10% sample intensity were not enough to contemplate all the species in the area and estimate the volume inside to the required accuracy limit, maximum of 10% sampling error. The treatments of 15% and 20% resembled the parametric value regarding floristic composition, species diversity and volumetry of the forest census of the area, showing no significant difference between them. The analysis of the phytosociological structure showed the importance of using sample inventories to evaluate the economic potential of an area and its suitability for forest management.

Forest Conditions

Human health related to forests can be evaluated by Health Impact Assessment (HIA) methodologies and by using indicators of Sustainable Forest Management (SFM). The HIA systematically reviews the health aspects associated with a development policy, plan or project for a forested area, whereas the indicators of SFM can be used to monitor and give information on the existing forests, and their management, including planning. A prerequisite for the assessment of human health aspects in forestry context is defining the relevant indicators. The physical and mental aspects of human health as well as human diseases related to forest conditions are not covered comprehensively and in an operational way for use in current forest management. The health aspects need more multidisciplinary research on the cause-effect relationships between health, forest management and biodiversity. It is also necessary to develop methodologies for the estimation of the economic value of the non-market forest ecosystem services. This article outlines several possibilities to collaborate and develop joint approaches between forest and health sector to assess the health aspect in forests and to ensure that the health aspects in forest management are taken into consideration.

Community forestry adoption basedon multipurpose tree species diversity towards to sustainable forest management in ICEF of University of Lampung, Indonesia.Biodiversitas 19: 1102-1109. Integrated Conservation Education Forest (ICEF) of University of Lampung (Unila) at Wan AbdulRachman (WAR) Forest Park is a conservation forest which should be free from any kinds of human activities. In fact, more than 75%the area has been managed by community hence there is a need for management strategy through Community Forestry (CF). It is knownthat there are a lot of Multipurpose Tree Species (MPTS) that can be utilized for the community’s daily life. The research’s objectivesare to analyze the ability of the community to adopt CF scheme, to calculate the diversity index of MPTS and level of Skill KnowledgeAttitude (SKA) and to determine the correlation variables to sustainable CF. This study used Shannon-Wiener diversity index, analysisof SKA level and regression analysis for adoption level. The results of this study noted that at the research site has diversity index 0.115and 74.29% of plants are MPTS. Based on the data analysis, 168 respondents [89%] agree to adopt CF scheme and level of their SKA ismoderate therefore needs to increase this level towards to forest sustainability. There are three variables of community forestry adoptiontoward to sustainable forest management at ICEF: number of trees species, the volume of forest products that would be sold, and rolesof extension education.

Silvicultural Prescriptions

A major component of sustainable forest management are the stands left behind after the logging operation. Large mechanized harvesting equipment involved in current forest management can inflict damage on residual trees; and can pose a risk of mortality from diseases, natural calamities, and/or degrade future economic value. The primary objective of this study was to evaluate the residual stand damage under different harvesting methods and silvicultural prescriptions i.e., crop tree release (CTR), diameter limit cut (DLC), and overstory removal (OSR). The second objective was to evaluate the intensity and frequency of damage occurring on the bole, canopy, and root at tree and stand level. The third objective was to document strategies adopted globally to minimize stand damage due to timber harvesting. Five harvest blocks implementing three silvicultural prescriptions, were selected as the treatments across two different industrial timberlands in central and northern Maine (Study Site (SS) I and II, respectively). A hybrid cut-to-length (Hyb CTL) and whole-tree (WT) harvesting method were employed for conducting the harvest in SS I and II, respectively. Systematic transect sampling was employed to collect information on type, frequency, and intensity of damages. The inventory captured 41 and 8 damaged trees per hectare with 62 and 22 damages per hectare from SS I and SS II respectively. Bole damage was the most frequent damage across all treatments. The Hyb CTL had lower damage density (damage per ha) and severity compared to WT. The average number of trees damaged per ha was higher for CTR prescriptions compared to DLC. There were no significant differences in the height of the damages from the ground level between treatments within each study site; however, there was a significant difference between the study sites. Species damaged was directly related to the residual trees left behind and was dominated by American beech, yellow birch, sugar maple, and eastern hemlock. Finally, the study provides strategies that can be adopted at different forest managerial phases to mitigate residual stand damage.

The paper is focused on the problem of developing a strategy for sustainable forest management and the forest sector of the economy of the territories. The aim is to improve approaches to its creation based on an ecosystem approach to generating real economic incomes from forest products and forest services and improving the environment. For this, the conceptual framework of the study based on the ecosystem approach is substantiated, considering the relationship between ecosystem services of the forest and various forms of their contribution to the economic development of territories, taking into account the forest and non-forest sectors of the economy. To determine the ecosystem services of the forest, the methods of direct counting, compara-tive analysis, assessment of “willingness to pay”, assessment of the carbon budget, etc. were used. The study of the economic value of the ecosystem services of the forest of transboundary territories showed the differences between the direct and indi-rect contribution of forests to the economy of the regions, which are determined by climatic features, the state of the forest fund, the degree of forestry activities, applied methods of forest management and forest use. The study made it possible to devel-op strategic directions for sustainable management of forest ecosystem services in transboundary terri-tories and to draw a conclusion about the need to move from a conservation type of forest manage-ment to the principles of sustainable development based on the preservation and enhancement of the economic, social and ecological value of forests.

When ecosystems are well managed, they are carbon sinks. The objective of this study is to know the state of the plant biodiversity of the wooded area of the Lokoli Ecofarm and its contribution to the regulation of the climatic regime, with a view to better conservation decision-making.A floristic inventory made it possible to determine the diversity and the floristic composition of the ligneous plants in the different Ecofarm habitats. Dendrometric measurements were carried out to determine the structural profile and the sequestered carbon stock of each habitat. The floristic study made it possible to identify 63 woody species divided into 251 classified into 22 families. The open forest has proven to be the richest in species and the most diverse. The structure in diameter classes reveals that the different biotopes are dominated by young tree stems, with a strong tendency to regenerate. The amount of carbon contained in the total biomass was found to be greater in the fallow (8.87 t / ha) than in the open forest (6.53 t / ha) and savannah (6.88 t / ha). The sequestered atmospheric carbon is estimated at 108.98 t / ha in total, for an economic value varying from 27,799.34 to 124,279.41 euros depending on the different carbon markets. In addition, this study showed that fallow significantly contributes to increasing the carbon sequestration potential of the Ecofarm.

Abstract In Poland, the stormy discussion on the future of the Białowieża Forest has been ongoing already for a long time. The disputes are mostly focused on seeking answers to two questions: how to protect these unique forest ecosystems and whether forest management threatens their naturalness. The discussion has grown stronger after the recent, enormous outbreak of Ips ypographus in the Forest. The Białowieża Forest has been managed for years with no significant negative effect. However, antagonists of foresters blame forest management for degradation of the Forest’s ecosystems, which is caused by favoring the economic value of timber expected to be harvested in keeping with the management plans of 3 forest districts located in the Białowieża Forest. At any rate, such assumption, has nothing to do with reality. During this discussion the idea to extend the national park for all the Białowieża Forest revived. In this paper, we reviewed the economic, social and ecological dimensions which should be taken into consideration before making a decision on extending the Białowieża National Park. It should be underlined that the Park’s area is already under the strict protection; furthermore, 2/3 of the area of neighboring managed forests are under legal protection (the nature reserves, NATURA 2000, the so-called reference forests, etc.). All things considered, we cannot find any reasonable purpose (ecological, financial or social) for expanding the Park’s area from 10 500 ha (present status) to 62 500 ha (after extension). Also, we are convinced that sustainable forest management conducted in managed parts of the Białowieża Forest, which comprises the fulfillment of all forest functions and services, should not be perceived as a signifcant threat to naturalness of the Forest’s ecosystems.

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.
