The diversity of mangrove vegetation is a community that has different characteristics from other communities. Diversity is an important component in mangrove management, but so far the availability of data related to mangroves is still very minimal, including those related to the species diversity of mangrove forest vegetation in the region. This study aims to obtain data on species diversity of vegetation found in the mangrove forest area of Dusun Besar Village, Pulau Maya District, Kayong Utara Regency. Method used was a combination of path and plot method, and the determination of the location and research path location were carried out using purposive sampling. The results of observation and data analysis showed that the dominant vegetation species with the highest importance value index (INP) for seedlings, saplings and trees was the Avicennia marina, namely the INP value of seedlings 37.04%, the INP values of sapling 65.24%, and the value of INP a tree rate of 65. Based on the results of the most dominant analysis found the species of  Avicennia marina with a value of C = 0.03430 for seedling, C = 0.04729 for sapling, and C = 0.04736 for tree level. The diversity of mangrove forest vegetation species in Dusun Besar Village for seedlings, saplings and trees is low because it has an H 'value <1, and the abundance of mangrove vegetation species was not evenly distributed in each forest area because it only has an e value <1.Keywords: Dusun Besar Village, Mangrove Forest, Species Diversity

ABSTRACT                This study aims to find out how changes in mangrove forest area and how the density of mangrove forests in Panikiang Island changes from 1998 to 2018. Analysis of changes used is the analysis of remote sensing images. The image used is satellite imagery LANDSAT 5 TM acquisition 1998 and LANDSAT OIL imagery acquisition in 2018. The guided classification method with the maximum like-lihood method is used to determine changes in mangrove forest area, while for non-guided classification using NDVI formula.                The results obtained in 1998 mangrove vegetation covering an area of 6.93 hectares experienced changes in land cover to non-vegetative mangrove and elsewhere on the island became 3.24 hectares of mangrove vegetation. Changes in the area of mangrove forests from 1998-2018 were 3.92 hectares.The density of the Pannikiang Island mangrove forest in 1998 with the class of meetings decreased by 34.56 hectares, the density class increased by 23.67 hectares and the density rarely increased by 7.2 hectares.

This paper attempts to identify and explicate sustainability approach through innovative management of natural resources that is able to create balance between conservation and utilization of natural resources. Innovative management of natural resources is related to the act of bringing changes or an introduction to a novelty idea for achieving organisational goal which involves organising people, finances and resources, training, controlling, monitoring, and sanctioning. The study focuses on the mangrove ecosystem, one of the most sensitive natural resources in the country, which has been successfully managed by the government through top down approach. Data was gathered through content analysis and interviews with several key persons from the study area. This paper firstly compares the different management approaches in Matang Mangrove Forest Reserve and Kuala Gula Mangrove, before finally elaborating on the innovative management of the latter.

Mangrove forest has a significant role in sequestering carbon gases from the atmosphere but there are lesser literature has been made on it. This research was conducted to quantify the aboveground, belowground and soil carbon stock in Sulaman Lake Forest Reserve, Sabah, Malaysia. Nine transect lines with 125 m length were established and a circle with 7 m radius was set in every 25 m. Forest inventory was done to get the diameter breast height of standing trees and soil sampling with four different depths (0-15 cm, 15-30 cm, 30-50 cm and 50-100 cm) were taken for soil analysis and bulk density. Allometric equation was used to calculate aboveground and belowground biomass then its carbon stock was estimated as 50% from its total biomass. The result shows the total carbon stock in the study area was 441.72 Mg C ha-1, and soil has the highest value of carbon stock (351.98 ± 11.73 Mg C ha-1) followed by aboveground carbon (67.30 ± 20.55 Mg C ha-1) and belowground carbon (22.44 ± 0.17 Mg C ha-1). This study found that soil carbon stock made up almost 80% of the total carbon stock in the mangrove forest. This ecosystem also shows a higher value of carbon stock compared to other locations hence emphasized the importance of prioritizing a mangrove forest in any climate mitigation efforts.

Abstract. Isroni W, Islamy RA, Musa M, Wijanarko P. 2019. Short Communication: Species composition and density of mangrove forest in Kedawang Village, Pasuruan, East Java. Biodiversitas 20: 1688-1692. Mangrove is one of ecosystems located in estuary and shallow coastal waters and its existence has a significant role for life. The aim of this study was to identify species composition and density of mangrove forest in Kedawang village, Nguling Sub-district, Pasuruan District, East Java, Indonesia. Survey method using belt transects was carried at three sampling points. Results of this study showed that mangrove vegetation in Kedawang includes five species from three families, namely Avicenniaceae (Avicennia alba and Avicennia marina), Rhizophoraceae (Rhizophora apiculata and Rhizophora mucronata), and Sonneratiace (Sonneratia alba). At sampling point 1, A. alba dominated with a density of 37 individuals/ha at tree level, 380 individuals/ha at pole level and 3100 individuals/ha at stake level. At sampling point 2, the tree level was dominated by A. alba with 142 individuals/ha, while R. mucronata dominated the pole and stake level with 1300 and 1467individuals/ha, respectively. At sampling point 3, the pole and stake level was dominated by A. alba with 167 and 933 individuals/ha respectively, while A. marina dominated the sapling level with 800 individuals/ha. At all stations, the density at stake level is greater than that tree level. Therefore, it is necessary to carry out conservation efforts in the form of protection combined with restoration by enrichment planting at all study locations to increase the diversity and density of mangrove vegetation.

<strong>Mangrove Forest Vegetation Potency to Mitigate Seawater Intrusion on Small Island.  </strong>Natural resources exploitation in the coastal areascaused serious problems for shallow ground wateravailabily especially in small islands. Small islands society such as in Ambon Island facesdrinking water quality degradation due to the sea water intrusion.Mangrove is one of the coastal ecosystemtypesthatis though to minimize sea water intrusion.However, the information about mangroveparametersthat can be used todetermine the mangrove forest patches potency in small islands to mitigate sea water intrusion is still limited. The aim ofthis study is to assess the correlationof mangrove vegetation and sea water intrusion using transect anddipole-dipole configuration geoelectric methods. The study showed that the thickness of mangrove vegetation and the size of mangrove trees determined the mangrove forest potencyto mitigatesea water intrusion.There was no sea water intrusion (relativity values:75.5-118 Wm)in Passo, due to thick mangrove vegetation (mean:320 m) and bigmangrove tree sizes (mean diameter: 19cm and mean height: 10m).Sea water intrusion was low (relativity values: 0.798-4.53Wm)in Poka due to thin mangrove vegetation (mean 10-100 m) and small tree sizes(mean diameter: 8.6cm and mean height: 5m). In contrasts, sea water intrusion was very high (relativity values: 1.4-9.2Wm) for the areas without mangrove vegetation(e.g. Lateri). These mangrove parameters were also negatively correlated with the distribution and coverage area of sea water intrusion.Mangrove patches in small islands can be used assea water intrusion mitigation tools, but theecosystem condition was already degraded or in the poor conditions. The findings of this study are useful for government as a basis in decision makingand to better manage of ground water and coastal ecosystem particularly mangrove.
