Abstract

An essential element relevant to forest sustainability is the state of health of the stand. Health conditions of trees can be affected by both biotic and abiotic elements. This study aims to identify tree damage in the protected blocks of the Bunder Forest Park (Tahura) in Gunungkidul, Yogyakarta, using three parameters: damage location, damage type, and severity level. Observations were carried out in three clusters using the Forest Health Monitoring (FHM) method in protection block. The results showed that 16 trees were categorized as healthy, 41 threes experieced minor damage, and 10 threes had moderate damage. The most frequent damage location on individual trees was found on the lower trunk. The most commonly observed type of damage was open wounds. The most frequent severity level was 20%, which indicates a low level of damage. Nevertheless, it is necessary to conduct monitoring of tree health in order to facilitate the sustainable management of the Tahura Bunder forest reserve.

Abstract

This study aims to identify and map the level of soil erosion vulnerability in Tewah Sub District, Gunung Mas Regency, Central Kalimantan Province. Identification of the level of soil erosion vulnerability was carried out using parameters of slope, soil type, rainfall and land cover. Field surveys were conducted to collect data on the area of ​​tree canopy cover at each level of erosion vulnerability. The results of the study indicate that in Tewah Sub District, which is included in the Kahayan Sub-Watershed have 5 levels of soil erosion vulnerability with categories of not vulnerable, less vulnerable, quite vulnerable, vulnerable and very vulnerable. Furthermore, it is known that ±50.23% of the research location area is included in the category of quite vulnerable and only ±0.29% is included in the category of not vulnerable. The value of ​​tree canopy cover has a significant effect on the level of soil erosion vulnerability. The higher the area of ​​tree canopy cover, the lower the level of erosion vulnerability. Thus, it can be concluded that erosion vulnerability due to lack of forest cover, especially in Tewah Sub District, must be a priority in handling to support the carrying capacity of the environmental ecosystem.

Abstract

Fundamental information about stands, particularly concerning structural diversity and composition, is crucial for comprehending the extent of plant species variety. This study is to analyze the structure and composition of species within the plant collection stands located in the protected area of Bunder Forest Park in Yogyakarta. The research efforts encompass the gathering of data on growth parameters like height, diameter, and crown width. The vegetation analysis data collection method entailed establishing observation plots in both square and transect configurations, each measuring 100 meters in length. The determined sample intensity was 3.3%, yielding 15 plots distributed over 3 transects, each measuring 100×20 meters. The plant species composition in plots 20 and 21 of the protection block in Tahura Bunder comprises 10 species: flamboyant, cajuputy, nyamplung, acacia, mahogany, teak, trembesi, gamal, jambu darsono, and tamarind. Transect 3 exhibited the greatest species variety. The vegetation structure in plots 20 and 21 is categorized within layers C and D. The main tree species in the stand, according to the Importance Value Index (IVI), is cajuputi (Melaleuca leucadendra), with an IVI of 208.27%. This study recommends enhancing plant species diversity to ensure the sustainability of genetic resources, particularly the indigenous species in the Tahura Bunder Yogyakarta region.

Abstract

The purpose of this study is to examine the vegetation's composition and ecostructure surrounding the Ramin tree (Gonystylus bancanus) in the University of Palangka Raya's Natural Laboratory of Peatlands. Vegetation data collection was carried out using the quadrat plot technique, with the plot placement applied through purposive systematic sampling. The Importance Value Index (IVI), species dominance index, diversity index, and evenness index were employed to examine the data from this research graphic using Microsoft Excel. In this study, 47 different plant species from different communities were identified and divided into 38 genera and 27 families (trees, poles, saplings and seedlings). The greatest number of species were found in the groups Myrtaceae and Dipterocarpaceae. There are no dominant species in the area with Nyatoh, Jambu-jambu, and Mangkinang nearly always occupy the five dominant species ranks from seedling to tree level at all peat thickness levels. While the species evenness index in all plant communities and the level of peat thickness are in the high/abundance category of almost evenly (E = 0.76 – 0.95), the majority of species diversity index (Shannon-Wiener value) in the research plots are classified as high (H'>3), indicating that the condition of the forest ecosystem at that location is relatively stable.

Abstract

Mangrove forests are one of the coastal ecosystems of tropical waters that have various potential benefits for both the environment and humans. The existence of mangrove forests is very necessary for the future of the earth. Mangrove forests have one very important function, namely as an absorber and store of carbon (C). Mangrove forests can store more than three times the average carbon storage per hectare by tropical land forests. This study aims to determine the carbon content and carbon absorption in leaves, roots and soil on the mangrove coast, especially in North Sinjai, Sinjai Regency. The method used in this study is the sampling method to measure the carbon content in leaves, roots and soil. The analysis will involve direct measurements in the field and laboratory analysis to obtain accurate data. The carbon content in mangrove leaves ranges from 0.9-0.11 tons/ha, with a carbon absorption capacity of 0.33-0.42 tons/ha. In the roots, the carbon content ranges from 0.44-0.72 tons/ha with an absorption capacity of 1.60-2.64 tons/ha. The carbon content in the soil ranges from 8.66-156.83 tons/ha with an absorption capacity of 31.79-575.55 tons/ha. This study can be used as basic data in future policies for climate change mitigation, especially the mangrove ecosystem in Sinjai Regency, South Sulawesi Province and can open up opportunities for carbon-based economic schemes such as carbon trading.
