Abstract Cypripedium calceolus is considered an endangered species in the territory of Poland. Population of this rare species, situated at Lake Kwiecko (Western Pomerania), was regularly monitored in the years 1986-2013. The studied population has been under the permanent influence of the nearby hydroelectric power plant for almost 45 years. The field observations showed that the power plant had no negative impact on the condition of Cypripedium calceolus population. An indication of its good condition was, among others, an increase in the size - from 150 to 350 specimens within the study period.

The data on the frequency, density and abundance of the lichens growing around the Moghla Coal mines, Kalakote has been recorded and compared with lichens growing in a forest area away from the coal mines to work out effect of coal mines on the diversity and distribution of lichens. The data revealed that pollutants released by the open coal mining activities not only effected qualitative distribution but also have effect on the quantitative parameters. Over all 10 species of lichens belonging to 9 genera and 6 families have been recorded from the vicinity of coal mines as compared to 15 species, belonging to 9 genera and 7 families, recorded from the forest area.

Five Factors

Rainwater-induced soil erosion occurring in the forest is a special phenomenon of soil erosion in many red soil areas. Detection of such soil erosion is essential for developing land management to reduce soil loss in areas including southern China and other red soil regions of the world. Remotely sensed canopy cover is often used to determine the potential of soil erosion over a large spatial scale, which, however, becomes less useful in forest areas. This study proposes a new remote sensing method to detect soil erosion under forest canopy and presents a case study in a forest area in southern China. Five factors that are closely related to soil erosion in forest were used as discriminators to develop the model. These factors include fractional vegetation coverage, nitrogen reflectance index, yellow leaf index, bare soil index and slope. They quantitatively represent vegetation density, vegetation health status, soil exposure intensity and terrain steepness that are considered relevant to forest soil erosion. These five factors can all be derived from remote sensing imagery based on related thematic indices or algorithms. The five factors were integrated to create the soil erosion under forest model (SEUFM) through Principal Components Analysis (PCA) or a multiplication method. The case study in the forest area in Changting County of southern China with a Landsat 8 image shows that the first principal component-based SEUFM achieves an overall accuracy close to 90%, while the multiplication-based model reaches 81%. The detected locations of soil erosion in forest provide the target areas to be managed from further soil loss. The proposed method provides a tool to understand more about soil erosion in forested areas where soil erosion is usually not considered an issue. Therefore, the method is useful for soil conservation in forest.

Support Decision Making

Several multi-criteria decision support methods have been introduced to sustainable management of natural resources, but different methods suit different planning situations. One way to support decision-making is to apply voting theory. In this study, a multi-criteria decision-support method based on voting theory, called multicriteria approval (MA), is applied to wood supply chain management in a forest area owned by the state of Finland. The area is called Leikko and is located in the rural municipality of Pieksämäki. MA seems to have some promising features in relation to participatory decision support. The most essential advantages are its ease and comprehensibility. MA is also able to deal with ordinal and imprecise information. Since the method does not demand much preference information from interest groups, the inquiries may be conducted using the Internet. In the case study, nine timber-harvesting alternatives were devised for the forest area. The study involved seven interest groups, whose representatives defined seven criteria by which the alternatives were compared. The purpose was to find a consensus or compromise solution for a practical harvesting schedule. Two different versions of MA were tested and compared from the participatory decision-support aspect. Usability and ease of method, the comprehensibility of the inquiries, and the congruence of the results were examined.

The purpose of this study was to determine the potential of natural and cultural resources, to know the perceptions, participation and aspirations of the community and to develop a community-based ecotourism development strategy in Selelos Village, Gangga District, North Lombok Regency. This type of research is a descriptive qualitative case study and exploratory descriptive to find the potential in the form of biodiversity in the Selelos forest area. Data collection was carried out by observing the biodiversity in it, testing water quality, and using a questionnaire to 50 community respondents and 7 respondents from the village government. The results showed that Selelos Village has a forest area ecosystem that holds several potentials to be developed into ecotourism, including: waterfalls, springs, customary forests, and plantations (agro-tourism). In addition, it has a diversity of flora and fauna, there are about 13 high-level plant families with many species in it, as well as about 5 families of fauna and there are also endemic animals such as partridge and deer (senggah). Of the four springs quality tested, all of them are suitable as raw material for drinking water. Meanwhile, based on the questionnaire analysis, the community and village government will work together in developing and managing ecotourism. Based on the SWOT analysis, the strategy used in developing ecotourism is to take advantage of the strengths of opportunity (S-O), among others; mapping the potential of ecotourism, developing special ecotourism such as agro-tourism, synergizing ecotourism with local culture and customs, equipping, providing facilities and infrastructure, and improving human resources.
