The community role is needed in the implementation of mangrove forest tourism management, especially in planning activities. The role of the community is the involvement of community itself in the development activities, both in the planning, implementation, evaluation, and the stages of esnjoying the results of the development itself. The purpose in this descriptive qualitative study was to determine the role of community in managing mangrove forest tourism in the subdistrict of Sukadana of Kayong Utara regency. Data collection techniques consist of observation, interviews, and documentation. While the analysis was carried out with descriptive analysis technique. The results of this study indicate that the role of of the sejahtera village community in managing mangrove forest tourism is limited to the maintenance of natural resources, maintenance of cleanliness and nursery of mangrove forests. Due to mangrove forest management is still fully managed by The Gunung Palung National Park Agency, the role of the community in the management of tourism in mangrove forests is still low. Therefore, the involvement of the surrounding community needs special attention and other related parties in utilizing mangrove forest tourism.Keyword: community role, mangrove forest, themanagement of mangrove tourism

Abstract The primary objective of this study was to characterise the edaphic conditions of forest areas in the Pieniny National Park (PNP), and to describe the dependencies between properties of forest soils and types of forest plant communities. The “Soil Trophic Index” (SIGg) for mountainous areas was applied. The evaluation of the trophism for 74 forest monitoring employed the soil trophic index for mountainous areas SIGg or SIGgo. Plant communities in the forest monitoring areas were classified according to the Braun-Blanquet’s phytosociological method. Soils of PNP present in the forest monitoring areas were mostly classified as eutrophic brown soils (72.9%), rendzinas (10.8%), brown rendzinas (5.41%), and rubble initial soils (5.41%). Pararendzinas, dystrophic brown soils, and gley soils were less common (total below 5.5%). In the forest monitoring areas of PNP, eutrophic soils predominate over mesotrophic soils. High SIGg index of the soils is caused by high values of acidity and nitrogen content. The Carpathian beech forest Dentario glandulosae-Fagetum and thermophilic beech forest Carici albae-Fagetum associations are characterised by high naturalness and compatibility of theoretical habitats. The soils of the Carpathian fir forest Dentario glandulosae-Fagetum abietetosum subcommunity is characterised by a higher share of silt and clay particles and lower acidity as compared to the Carpathian beech forest Dentario glandulosae-Fagetum typicum subcommunity. The soils of the forest monitoring areas in PNP stand out in terms of their fertility against forest soils in other mountainous areas in Poland.

This paper deals with large-scale mountain forest decline in the Šumava National Park. The changes in biotic and abiotic properties of forest sites follow the tree layer disintegration. Changed microclimatic conditions such as intensity of irradiance, moisture and temperature of the top holorganic layers together with altered development of ground vegetation could strongly affect the values of microbiological respiration activity and the rates of nitrogen mineralization and nitrification. Soil substrates, built of organic mater, located on stony locations, are endangered by introskeletal erosion. This paper compares these features in pairs of research plots, consisting of dead or cut forest and of living stand. According to the results of this study, higher rates of organic matter decomposition, transformed dynamics of nitrogen and other nutrients and possible nutrient leaching from soil solutions were demonstrated in the forest floor under declined spruce stands. The extent and seriousness of these adverse processes for forest soils are strongly site dependent.

This research aims to determine the spesies compossition and distribution pattern of Gastropod and its relationship with abiotic factors (pH, salinity, soil texture, and organic content of the soil, and the high of tide of the eustuary area) in the Mangrove forest at Blok Beduk Segoro Anak Alas Purwo National Park. This research was conducted on February 2013. Data was taken four times using a week time interval during one month. Every observation covered eight stations, where station 1 to station 4 consist of four transects and 40 plots, while station 5 to station 8 consist of 3 transects with 42 plots and each plot was 5 m × 5 m. Gastropod observed from each plot are preserved with 70% alcohol and identified in Malakologi Laboratory, Indonesian Institute of Sciences (LIPI). Results of the research reveated that the Gastropod observed consist of 19 families and 37 species, and the dominant family is Ceritidae. The Diversity index of Shanon Wiener was 0.53 (low deversity). Two available of Distribution pattern, group (Canarium labiatum, Cassidula nucleus, Cerithium coralium, Chicoreus brunneus, Cassidula vespertilionis, Cerithidea cingulata, Cerithidea quadrata, Chicoreus capucinus,Conus rattus, Conus striolatus, Ellobium aurisjudae, Littorina carinifera, Littorina scabra, Monodonta labio, Nassarius melanoides, Nassarius olivaceus, Nerita balteata, Nerita planospira, Nerita undata, Pugilina ternatana, Sphaerassiminea miniata, Telescopium telescopium, Terebralia sulcata, Thais intermedia), random (Angaria delphinus, Conus catus, Conus omaria, Cymatium moniliferum, Erronea errones, Oliva oliva, Polinices aurantius, Pollia undosa, Tectus pyramis, Trochus californicus, Turbo argyrostoma). The abiotic factors had relatianship not significantly (p = 0.067) on Gastropod distribution pattern. Keywords : Distribution pattern,Gastropod, species compossition
