“…Based on the guidelines for inventory and identification of mangrove critical land by the Indonesian Ministry of Forestry of 2005, mangrove seedlings in the study site were categorized as very low, with sapling density <1,000 individuals/ha and seedling density <2,000 individuals/ha. The density value of mangrove budding in Keboromo Village has lower results than research in Segara Anakan by Ananta et al (2020) with a value of 10,230 individuals/ha for saplings and 17,460 individuals/ha for seedlings and research in Benoa Bay by Andiani et al (2021) with a sapling density value of 901 individuals/ha, but has a higher value than the research of Istomo et al (2019) in Baluran with a value of only 108 individuals/ha. Based on the statement of Koswara et al (2017), low mangrove seedlings in a location can be caused by several common factors such as the age of the ecosystem which is still relatively young, the level of utilization and herbivory of mangrove fruit, the tidal cycle, environmental incompatibility, and garbage pollution.…”

Mangrove degradation is one of the most common issues in the coastal areas of Java, which can cause ecological impacts and even disadvantage for local community. The mangrove forest degradation can be identified based on the vegetation analysis results, which could potentially contribute to the mangrove ecosystem management and rehabilitation programs in the coastal areas. Mangroves in Keboromo Village was the rehabilitation and cultivation area, but often get damaged by ocean waves. This study aims to determine the ecological and vegetation conditions of mangrove ecosystems consist of species composition, density, canopy cover, tree height, and environmental parameters were held in February 2023. The method used was direct observation using transect quadrants of 10x10 m2. The average mangrove density of all observation stations was 3.425 individuals/ha for the tree category, 575 individuals/ha for the sapling category, and 250 individuals/ha for the seedling category. The average percentage of canopy cover was 78.41%. The average height of mangrove trees at all stations is 4.15 m. The environmental parameters were still compatible with the water quality standard for biota and mangrove life. The mangrove forest degradation level based on standard criteria and guidelines for determining mangrove degradation is categorized as low, indicated by mangrove density >1500 individuals/ha and canopy cover >75%. Poor conditions were measured for sapling and seedling densities, which may be caused by environmental factors unsupportive for mangrove regeneration. Based on the results of mangrove vegetation analysis in Keboromo Village, it can state the mangrove ecosystem condition is good. However, management programs are needed to keep the mangroves sustainable.

“…Melimpahnya komunitas mangrove di Bali diikuti dengan banyaknya penelitian mengenai mangrove, terutama di kawasan Tahura Ngurah Rai yang memiliki tutupan mangrove terluas di Bali. Beberapa diantaranya adalah korelasi tegakan mangrove terhadap simpanan karbon (Andiani et al, 2021), regenerasi alami pada semai mangrove (Dewi et al, 2021), struktur vegetasi mangrove berdasarkan karakteristik biofisik (Imamsyah et al, 2021), struktur komunitas mangrove berdasarkan karakteristik substrat (Prinasti dkk., 2020), distribusi spasial dan indeks kesehatan mangrove pada tiga genus dominan (Sugiana et al, 2022), dan perbandingan vegetasi mangrove di area alami dan bekas tambak (Wijaya et al, 2023). Meskipun demikian, penelitian pendukung seperti data polen masih sangat kurang.…”

The diversity of mangrove species in an area can be observed through morphological structure, anatomy, as well as palynology. Palynology is a study of pollen that frequently used as a reference to support data in identifying mangrove species. Mangrove areas in Bali have patchy distribution, one of which can be found in the Batu Lumbang area. Batu Lumbang is a mangrove area that is part of the Ngurah Rai Forest Park. Observation of the micromorphological characteristics of pollen in the Batu Lumbang mangrove forest area was carried out through the acetolysis method with modification. Eleven mangrove species were sampled, comprised of Aegiceras corniculatum, Avicennia marina, Bruguiera gymnorhiza, Ceriops tagal, Exoecaria agallocha, Lumnitzera racemosa, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Sonneratia caseolaris, and Xylocarpus granatum. The results of observations on pollen from eleven species of mangroves show similarities of pollennits, monads. In addition, other pollen characters such as aperture type, pollen shape, and pollen size categories found vary among the samples observed. These characters can also group several species that have the same family or genus. In turns, these can be used as diagnostic character to distinguish one species with another.

“…Mardliyah et al [21] revealed that the height of the stand has an effect on the biomass value which increases along with the growth of the stand (diameter and height) which will produce a large biomass value and stored carbon. However, Andiani et al [22] obtained a relatively weak relationship with tree diameter.…”

This research was conducted from May – August 2023 in the rehabilitation mangrove area of Kedaburapat Village, Rangsang Pesisir Sub-District, Kepulauan Meranti Regency, Riau Province. This study aims to determine the average of tree diameter, potential biomass and carbon storage of each tree and the relationship between potential biomass and carbon storage with the diameter of the Avicennia alba rehabilitation mangrove trees in Kedaburapat Village. The method used in this study is a survey method and determination of sampling points by purposive sampling. The potential biomass and carbon storage of each tree were calculated using the allometric method. The relationship between average tree diameter and potential biomass and carbon storage was analyzed using simple linear regression. The average diameter at breast height (DBH) of A. alba per tree ranged from 2.81 – 4.03 cm, the average biomass per tree was 7.39 – 12.80 kg, the average carbon storage per tree was 3.47 – 5.00 kg C and tree carbon total per ha was 32.62 – 43.95 ton C/ha. The potential of biomass and carbon storage of each tree has a relatively strong positive relationship with the average tree diameter, with a correlation coefficient (r) of 0.9921. The quality of the waters measured in this study were temperatures ranging from 28-30°C, salinity 25-28‰, and pH 7.5-7.9. Environmental parameters indicate that the condition of the rehabilitation mangrove area in Kedaburapat Village is still good and can support the life of mangrove vegetation.
