This study was conducted to determine the diversity of vegetation species that compose mangrove forests in the village of Medan Mas, Kubu Raya Regency. Measured parameters of important value index , dominance index (C), species richness index (RI), species evenness index (e) was carried out using the survey method by means of a plot. The placement of the research path was done (purposive ). The path made in this study is 10 meters wide (5 m to the left 5 m to the right) and the path length is adjusted to the conditions in the field to the river boundary. From the pathway, a sub-plot is made with a size of 10 m x 10 m for the tree level, and 5 m x 5 m for the sapling level and 2 x 2 for the seedling level. The results of this study indicate that the types found in the field amounted to 12 species for seedlings, 10 species for saplings and 9 species for trees. . Based on the results of the data obtained, it is known that the index value of species diversity (H) at seedling, sapling and tree levels shows a number <1. This means that the value of species diversity found in mangrove forests in Medan Mas Village is relatively low. Forests with low species diversity values indicate that the forest area has experienced forest disturbance or damage. When data collection is carried out in the field, there are several locations that experience disruption or damage in the form of logged-over or transfer functions as shrimp ponds.Keywords: Mangrove Forest, Vegetation Diversity

The activities of the community around the peat swamp forest cause disruption of the ecosystem from the sustainability of the forest area's resources. Land clearing and peatland fires also affect the presence of ferns. The new environmental conditions due to changes in land cover cause ferns to be affected by these changes. Kuala Dua Village Kubu Raya Regency has secondary peat swamp forest and open peat land due to fires 3-4 years earlier so it is overgrown with a variety of new types of flora, one of which is a type of fern. The objective of the study is to describe species diversity of ferns and their site conditions in secondary peat swamp forests and open peatlands of Kuala Dua Village, Kubu Raya District. This research was conducted with survey method using multiple plot samples. The plots determination was done by purposive sampling which was taken place on the site where there were many species of ferns land. Three plots were on each land covered condition with a plot size of 5 m x 5 m that divided into 25 of a 1 m x 1 m sub plots. The results show that 5 species of ferns found in peat swamp forest and 4 species of ferns were found on open peatlands. The species that has the highest INP value in the forest was Asplenium belangeri and the species that has the INP value in open peatland was Nephrolefis falcata. Dominant Index, Spesies Diversity Index and Spesies Abudance Index were 0,12 and 0,18; 0,30 and 0,36; 0,51 and 0,52 on the forest and open peatland respectively. The Similarity Index value (IS) of ferns in secondary peat swamp forest and open peatland is 44%.

Abstract Nature-based tourism relies on the beauty of nature to maintain sustainability and attraction. However, karst environment is vulnerable to disturbance due to tourism activity. This study, therefore, aims to analyze the social, ecological, physical, real, and effective carrying capacity of Pattunuang Assue Nature Tourism Object, Bantimurung Bulusaraung National Park. Data were collected through field measurement, observation, and interviews. Data of visitors’ favorite spot and its size were measured through observation and field measurement. Visitors’ perceptions related to the destination, including their duration activities were collected through interviews. It was further collected by observing the various spots of activity, and measuring the area of restrictive factors such as physical (number of rainy days), biotic (vegetation diversity at tree level, the diversity of birds during the busy visiting hours, the initial period of the Tarsius fuscus’ birth). We also observe the equipment and infrastructure of the destination and collected data related to management through interviews with the managers. This study reveals various carrying capacity value which can be used as an option for the managers to choose the best way to manage destination in the right way. The result showed that particular activities exceeded carrying capacity but other activities far below their carrying capacity value. The study furthermore discusses how to deal with numerous activities. It also suggests an increase in the number of visitors by considering their ecological characteristics and management capacity.

Data on crab species in the Mangrove Ecotourism Area Pagatan Besar Village, Tanah Laut Regency is not yet available. The purpose of this study was to describe the species of crab in the mangrove ecotourism area and explain its density and diversity. Three walkways that are made of ironwood (Eusideroxylon zwagery) with a width of about 1.5 m and a length of about 100 m stretch about 1.5 m above the mud surface. The three wooden walkways were used to observe species and count the number of crab individuals found in the sample plots. For each wooden walkway, there were 6 (1 m x 1 m) plots on the left and 6 (1 m x 1 m ) plots on the right. The distance between plots from the land to the sea was 20 m. Seven crab species are described. Two of them are crabs that are active at night. All crab species become denser along with the qualitative existence of mangrove forests and their shade to the environment and the substrate below. On the other hand, species diversity is thought to be influenced by the type of substrate (clay and sandy loam) and exposure by sunlight.
