The condition of mangrove forests on the east coast of East Lampung Regency is currently experiencing degradation and has suffered a lot of damage due to various causes and problems it faces. This condition causes the role and benefits and functions of mangrove forests to decrease, especially in climate change. Therefore, to determine the condition of the mangrove forest, periodic monitoring and assessment of mangrove forest health is required. The purpose of this study was to determine the importance of mangrove forest health in climate change. To achieve this, the stages include: determining the number of plot clusters to be made, making cluster plots, measuring the health of mangrove forests based on ecological indicators of mangrove forest health, processing and analyzing mangrove forest health data using SIPUT (Assessment Information System) software. Forest Health), and categorization and health assessment of mangrove forests. The results of this study indicate that the condition of mangrove forests on the East coast of East Lampung Regency in general has a forest health condition in the medium category. So, knowing the health condition of mangrove forests will affect climate change. Forest health makes mangrove plants grow with good physiological processes so that they can absorb carbon dioxide in the atmosphere optimally. These conditions will make the environment better.

Abstract The surrounding community widely uses mangrove forests as a fulfillment of life. This requires an efforts to preserve the mangrove forest so that no damage occurs. This study aimed to determine the internal factors that affect the health condition of mangrove forests. The research method used to obtain internal factor data is by measuring the ecological indicators of forest health using the Forest Health Monitoring (FHM) method, then the data is processed by the Multiple Regression Analysis method using SPSS 20 through data on internal factors of mangrove forest health which are analyzed for their effect on health conditions of the mangrove forest. The results showed that the significant value of the regression was 0.008 ((α = 0.05) > 0.008), this means that simultaneously the independent variables (tree damage, crown damage, Cation Exchange Capacity-CEC, and biodiversity have an effect on the dependent variable (mangrove forest health) at the level of = 5%. Furthermore, through individual regression coefficients from internal factor data, it is found that the internal factors of biodiversity indicators in measurements 1 and 2 and crown conditions in the second measurement do not affect forest health conditions. Therefore, this research concludes that the internal factors that affect the level of forest health in the first measurement are vitality indicators (tree damage/cluster Plot Index-CLI and crown condition) and site quality indicators (CEC). Meanwhile, in the second measurement, there was a change in the crown condition parameters, which did not significantly affect forest health.

Mangrove forests have a special function, namely as a green belt which is certainly very important for human life. Health of forests, especially mangrove forests, is often overlooked regarding their health conditions. The health condition of the mangrove forest is very influential on its sustainability, so to know its health, one of the indicators that can be used is fauna biodiversity. Fauna biodiversity can be known by using the FHM (Forest Health Monitoring) method to determine the diversity and condition of health status. Mangrove forest in Pasir Sakti Sub-District, East Lampung Regency has a diversity of 9 species of birds and 5 types of epifauna diversity. Based on this, the Mangrove Forest of Pasir Sakti District, East Lampung Regency has a good forest health status.

The mangrove forest provides various ecosystem services in tropical and subtropical regions. Many of these services are driven by the biogeochemical cycles of C and N, and soil is the major reservoir for these chemical elements. These cycles may be influenced by the changing climate. The high plant biomass in mangrove forests makes these forests an important sink for blue C storage. However, anaerobic soil conditions may also turn mangrove forests into an environmentally detrimental producer of greenhouse gases (such as CH4 and N2O), especially as air temperatures increase. In addition, the changing environmental factors associated with climate change may also influence the N cycles and change the patterns of N2 fixation, dissimilatory nitrate reduction to ammonium, and denitrification processes. This review summarizes the biogeochemical processes of C and N cycles in mangrove forest soils based on recently published studies, and how these processes may respond to climate change, with the aim of predicting the impacts of climate change on the mangrove forest ecosystem.

Mangrove forests play a global role in providing ecosystem goods and services in addition to acting as carbon sinks, and are particularly vulnerable to climate change effects such as rising sea levels and increased salinity. For this reason, accurate long-term monitoring of mangrove ecosystems is vital. However, these ecosystems are extremely dynamic and data frequency is often reduced by cloud cover. The Continuous Change Detection and Classification (CCDC) method has the potential to overcome this by utilising every available observation on a per-pixel basis to build stable season-trend models of the underlying phenology. These models can then be used for land cover classification and to determine greening and browning trends. To demonstrate the utility of this approach, CCDC was applied to a 30-year time series of Landsat data covering an area of mangrove forest known as the Sundarbans. Spanning the delta formed by the confluence of the Ganges, Brahmaputra and Meghna river systems, the Sundarbans is the largest contiguous mangrove forest in the world. CCDC achieved an overall classification accuracy of 94.5% with a 99% confidence of being between 94.2% and 94.8%. Results showed that while mangrove extent in the Sundarbans has remained stable, around 25% of the area experienced an overall negative trend, probably due to the effect of die-back on Heritiera fomes. In addition, dates and magnitudes of change derived from CCDC were used to investigate damage and recovery from a major cyclone; 11% of the Sundarbans was found to have been affected by Cyclone Sidr in 2007, 47.6% of which had not recovered by mid-2018. The results indicate that while the Sundarbans forest is resilient to cyclone events, the long-term degrading effects of climate change could reduce this resilience to critical levels. The proposed methodology, while computationally expensive, also offers means by which the full Landsat archive can be analyzed and interpreted and should be considered for global application to mangrove monitoring.

Mangrove forest ecosystems can be interpreted as a unique and distinctive form of ecosystem, so that it is able to provide many benefits, ranging from socio-economic or ecological terms to the surrounding ecosystem. Mangrove forest in Margasari Village is a mangrove forest ecosystem that has physical, economic and ecological potential that needs to be maintained through sustainable forest management. One of the ways to manage mangroves is by monitoring forest health. Forest health monitoring that is applied periodically within a forest type can achieve sustainable forest management achievements so as to support better forest quality and quantity and can be a reference in making the right decisions in mangrove forest management so that the results obtained can be optimal. This study aims to obtain the value of the health status of mangrove forests in East Lampung Regency in order to ensure the sustainability of the forest. The study was conducted using themethod Forest Health Monitoring (FHM). The results of forest health monitoring showed that there were 4 plot clusters with the final value of forest health status in the medium category plot 1 (5.63), cluster plot 2 (3.51) poor category, cluster plot 3 (4.92) poor category, and cluster plot 4 (7.57) in good category. Thus the results of forest health monitoring obtained in the mangrove forest of Margasari Village with an average final value of forest health status of 5.41 which is included in the medium category.

Mangrove forest is a tropical beach vegetation community dominated by several tree species that can grow and develop in tidal and muddy beaches. Some mangrove areas recently have been damaged due to illegal activities carried out by various parties, one of which is the East Coast of Sumatra in the Sub District Percut Sei Tuan, Deli Serdang District, Province of North Sumatra. The purpose of the activities is to focus on replanting mangrove lands that have been damaged by local species. The growned in Tanjung Rejo Village Percut Sei Tuan buds are like Rhizopora stylosa, Rhizopora apiculata and Avicennia marina type. Percentage of growing plants were R. stylosa (92.37%), R. apiculata (90%), mixed propagules of R. stylosa and R. apiculata (90%) and A. marina (56%) respectively. Overall the rehabilitation of mangrove forest is categorized as successful, but only one species of the smallest growing with percentage is A. marina (56%) this is because the location of  planting is adjacent to the sea where the plants can not stand the tidal currents.

AbstractUrban development is driving the loss and subsequent fragmentation of mangrove forests in Penang, Malaysia. However, little research has focused on the implications of urbanization onto the biodiversity within mangrove forests. This study investigates and compares both vegetation and crab assemblages between urban and rural mangrove forests. Collectively, 5853 trees were recorded including 15 species from six families: Acanthaceae, Arecaceae, Lythraceae, Malvaceae, Meliaceae, and Rhizophoraceae. Avicennia marina accounted for 88.6% of all trees in the study and held the highest species importance (IV). Although the total number of mangrove tree species varied significantly between urban (14) and rural (7) mangrove forests, the mangrove forest structure based on IV did not vary significantly. In total, 633 crabs were recorded comprising 13 different species from three superfamilies: Grapsoidea, Ocypodoidea, and Paguroidea. Crab species richness did not vary between urban and rural sites, but the biomasses of five and the densities of four crab species varied significantly. Redundancy analysis (RDA) indicated that land use, salinity, and abundance of Avicennia officinalis can best describe the distribution of crab species (r2 =32.7). This study indicates that smaller fragmented urban mangroves at the east coast of Penang have a relatively high tree and crab diversity and are worth protecting, in addition to the larger mangrove forests on the west coast. The preservation of small yet interconnected mangrove sites could be critical to the recruitment of their flora and fauna and should be considered in decision-making processes.

“Mangrove” is the generic name for plants growing on tropical and subtropical tidal flats. The mangrove is used for many things, including disaster protecting land from high waves and tides and tsunamis, cleaning rivers and drainage containing soil and sand, and providing a variety of organisms with living space. Climate change and rising sea levels are threatening the future of the mangrove. Developing effective ways to conserve mangroves is thus needed, but more must be known about how the mangrove’s ecology and how it develops. It has been pointed out, for example, that mangroves increased flooding by the Sumiyo River in Amami Oshima. We studied ways to develop the mangrove at the Sumiyo River mouth in Amami Oshima and its influence in local flooding, finding that the current mangrove forest had little influence on flooding and that sediment deposition accelerating in Sumiyo Bay due to a sea dike could enlarge the mangrove forest in future.
