DocumentSpatial distributions pattern and associations of dead woods in natural spruce-fir secondary forests

No results found.Natural secondary forest is the main part of forest resources in China. Studying dead woods (DW) could better reveal the community succession rule and promote the healthy development of them. We investigated basic characteristics and coordinates of each tree (DBH≥1 cm) within a plot (100 m×100 m) using the adjacent grid method and studied the spatial distributions pattern and associations of DW (in the last five years) in a typical natural spruce-fir secondary forest in Jingouling Forest Farm, Wangqing Forestry Bureau, Jilin Province, China. The results showed that the diameter class distribution of DW showed the pattern of left-single-peak curve, while the logs showed the pattern of multi-peak curve. DW number was related to the mixing degree of one species, but not to the total number of it. The distribution of DW was concentrated at 0~8m scale. As the scale increases, it changed to random or uniform. The aggregation distribution of DW of medium (10 cm≤DBH<20 cm) and small (1 cm≤DBH<10 cm) DBH at small scale below 8 m was the main reason for the aggregation distribution of DW. The DW of large (DBH≧20 cm) DBH and Saplings (1 cm≤DBH<5 cm) showed a significant positive association at 2~25 m scale. There was no significant spatial association between DW and Small trees(5 cm≤DBH<15 cm). At 0~3m scale, there was a positive association between Medium trees (15 cm≤DBH<25 cm) and DW of small and medium DBH. At the 9 m, 11~14 m scale and the 15 m, 42~45 m scale, the DW of small and medium DBH were significantly negatively associated with Large trees (DBH≥25 cm). In conclusion, the biological traits, diameter class distribution and spatial distribution affected the abundance and diameter class distribution of DW of one species. The spatial distributions of DW and the associations between DW and standing trees varied across diameter classes and scales. Rational utilization of spatial information could optimize stand structure and promote positive community succession.

ArticleReorientation in management and utilization of non-timber forest products commodity based on the local knowledge under new forest management unit in Indonesian New Guinea

No results found.Non-timber Forest Products have played the important roles to the entire livelihoods of the indigenous community living inside and outside the forest areas. These non-wood products are being ignored because of several reasons ranging from inadequate of formal regulations, which are mostly focused on timber harvesting,lack of data on their distributions in nature, less capital investment to their diversities is enormous made them difficult to put in the nomination focus. It seems that these forest product commodities are being neglected despite of their irreplaceable contribution of local and indigenous community in fulfilling their daily foods, energy, medicinal plants, protein, and other essential substances. Utilization of non-timber forest products in Indonesian New Guinea could be divided into seven classifications such as a) staple foods for carbohydrates, vitamin, mineral, protein and lipid, b) energy for daily cooking and warming traditional house or huts, c) material for traditional constructions of sea or river transportation, housing wall and roofing, d) sources of medicinal plants and herbs from nature, e) raw material for traditional handcraft (dyeing, natural fibres, sculpture), f) an extra income and informal works by direct selling their harvested non-timber commodities when their necessities are fulfilled, g) customary land right that could not be sold, transferred or replaced as natural forest providing shelter for ancestors, inspirations, magic, and others. Utilization of non-timber forest products have to be focused with local products already existed, and intervention could be focused for value added purposes such as branding, labeling, packaging, standardization, and marketing chain implemented as the new directions to improve direct contributions to local and indigenous community.

ArticleOur relationships with forests define the future forests: a case of national institutions and personal perceptions of private forest owners and forest professionals in Finland

No results found.Our attitudes toward forests can be defined as human-forest relationships. These relationships are the result of our national context, the society where we live, cultural background, family and individual aspects, and of course, forests surrounding us. Human-forest relationships combine both historical and modern values and practices, reflecting the constantly evolving global, national, communal, and individual aims for future forests. Several disciplines have scrutinized people’s relationships with surrounding nature from various viewpoints, although partly disregarding forests’ unique characters and importance for societies and local communities. Our ongoing research asks what kind of relationships with forests are defined in national institutions, and expressed among private forest owners and forest professionals. The importance of research results lies especially in two grounds to which human-forest relationships affect, firstly, the acceptance or changes of current forest management practices, and secondly, activities in mitigating climate change securing our common future. The main data consist of selected national forest institutions and around 100 in-depth interviews of private forest owners and forest professionals. Qualitative data are analyzed in a theoretical framework consisting of both new institutionalism and phenomenological and narrative approaches in a multidisciplinary combination of social sciences, forest policy, and ethnology. Preliminary results reveal emerging changes in forest institutions that strengthen non-economic aims. Both private forest owners and forest professionals are partly in a state of confusion pondering what are the right institutions and actions for a sustainable future. We discuss the human-forest relationships that exist both at the national level and among individual stakeholders. We aim also to clarify the importance of existing human-forest relationships for conflict resolution and sustainable forestry.
