“…Recent efforts are underway in the UAE to restore marine ecosystems, and the Aquaculture and Marine Studies (AMSC) has planted 5,026 hectares of A. marina in Abu Dhabi Emirate (Yosef et al, 2022). Research is underway in the UAE to utilize treated sewage effluent as a water-source to enhance the growth of mangrove seedlings in nurseries (Erftemeijer et al, 2021). This research was linked to the growing evidence that treated sewage enhances mangrove growth due to the lower salinity and the high nutrient concentration of this media (Burt et al, 2021).…”

Mangrove forests in the Gulf Cooperation Council (GCC) countries are facing multiple threats from natural and anthropogenic-driven land use change stressors, contributing to altered ecosystem conditions. Remote sensing tools can be used to monitor mangroves, measure mangrove forest-and-tree-level attributes and vegetation indices at different spatial and temporal scales that allow a detailed and comprehensive understanding of these important ecosystems. Using a systematic literature approach, we reviewed 58 remote sensing-based mangrove assessment articles published from 2010 through 2022. The main objectives of the study were to examine the extent of mangrove distribution and cover, and the remotely sensed data sources used to assess mangrove forest/tree attributes. The key importance of and threats to mangroves that were specific to the region were also examined. Mangrove distribution and cover were mainly estimated from satellite images (75.2%), using NDVI (Normalized Difference Vegetation Index) derived from Landsat (73.3%), IKONOS (15%), Sentinel (11.7%), WorldView (10%), QuickBird (8.3%), SPOT-5 (6.7%), MODIS (5%) and others (5%) such as PlanetScope. Remotely sensed data from aerial photographs/images (6.7%), LiDAR (Light Detection and Ranging) (5%) and UAV (Unmanned Aerial Vehicles)/Drones (3.3%) were the least used. Mangrove cover decreased in Saudi Arabia, Oman, Bahrain, and Kuwait between 1996 and 2020. However, mangrove cover increased appreciably in Qatar and remained relatively stable for the United Arab Emirates (UAE) over the same period, which was attributed to government conservation initiatives toward expanding mangrove afforestation and restoration through direct seeding and seedling planting. The reported country-level mangrove distribution and cover change results varied between studies due to the lack of a standardized methodology, differences in satellite imagery resolution and classification approaches used. There is a need for UAV-LiDAR ground truthing to validate country-and-local-level satellite data. Urban development-driven coastal land reclamation and pollution, climate change-driven temperature and sea level rise, drought and hypersalinity from extreme evaporation are serious threats to mangrove ecosystems. Thus, we encourage the prioritization of mangrove conservation and restoration schemes to support the achievement of related UN Sustainable Development Goals (13 climate action, 14 life below water, and 15 life on land) in the GCC countries.

“…Nutrient limitations have been reported among mangroves responding to it by developing physiological strategies such as increasing root biomass (Alhassan and Aljahdali 2021). Carbonate sediments which low in organic matter can be sourced from the adjacent seafloor of the shallow shoal surrounding the island (Erftemeijer et al 2021).…”

“…The information on forest structure is useful as the basis for management planning and decision making to achieve sustainable management of mangrove forests and their associated ecosystem services (Njana 2020). Other studies have also been focused on various themes, including species diversity (Perera et al 2013), habitat suitability for mangrove conservation (Samal et al 2023), mangrove growth and survivorship (Kathiresan et al 2019;Goldberg and Heine 2021) and mangrove adaptation in extreme environment (Erftemeijer et al 2021). Distribution of species and tree sizes, growth and yield provide useful information on management planning Indonesia has the largest extent of mangroves in the world, scattered along the coastline of the provinces on the country.…”

Abstract. Wintah, Kiswanto, Hilmi E, Sastranegara MH. 2023. Mangrove diversity and its relationships with environmental conditions in Kuala Bubon Village, West Aceh, Indonesia. Biodiversitas 24: 4599-4605. Mangrove ecosystem plays various ecological and socio-economic roles. Indonesia has the largest extent of mangrove forest one of which is located in West Aceh Regency, Aceh Province. The aim of this study was to assess the diversity and structure of mangrove forest in Kuala Bubon Village, West Aceh, and to analyze the relationships between the existence of mangrove species and the environmental conditions. Field survey was conducted from May to August 2022 using plot sampling method on three stations representing various habitat characteristics. Vegetation sampling using a 10 x 10 m2 plot as well as measurement on physical parameters (pH, salinity, and temperature) and chemical parameters (sediment texture and organic carbon content) were conducted. The relationship between the presence of mangrove species and the environmental parameters was analyzed using Principal Component Analysis (PCA). The result of vegetation sampling recorded 6 mangrove species, i.e., Rhizophora stylosa Griff, Sonneratia alba Sm, Avicennia marina (Blume), c, and Sonneratia caseolaris (L) Engl. This study revealed that the presence of Rhizophora stylosa Griff was related to the conditions of the clay substrate, pH and temperature values. Meanwhile, the existence of Rhizophora apiculata Blume, Rhizophora mucronata Lamk, Sonneratia alba Sm, Sonneratia caseolaris (L) Engl, and Avicennia marina (Blume) was related to the conditions of the silt substrate, diameter and salinity. Based on the results of relationship analysis, silt substrate and salinity have a correlation to maintain the mangrove ecosystem.

“…A total of 100 mature and healthy Rhizophora mangle L. propagules considerably in same length size were collected from mangrove patches in Sitio Bulo, Bulacan, Malalag, Davao del Sur. Mature propagules were identified having a ring-like mark (abscission layer) below the pericarp (ERDB-DENR, 2010) [17] .…”

This study investigated the potential of seaweed extract of Kappaphycus alvarezii as biostimulant in 3% concentration on the relative growth rate, net assimilation rate, and root to shoot ratio of mangrove propagules of Rhizophora mangle L. through different day-intervals of foliar application under field experiment. There were two factors included: factor A-types of treatment (A1-water, A2-seaweed extract, A3-commercial biostimulant); and, factor B-different day-interval of application (B1-4 days, B2-8 days, B3-12 days). It was revealed that 3% concentration of seaweed extract of K. Alvarezii had no significant effect on the rate growth rate, net assimilation rate, and root to shoot ratio of mangrove propagules of R. Mangle L. Moreover, seaweed extract of K. Alvarezii as biostimulant in 3% concentration had no significant difference to the commercial foliar biostimulant and to the different dayintervals of application. This study recommends to explore higher concentration of seaweed extract from K. Alvarezii on propagules of R. Mangle L. and other mangrove species in a greenhouse setting.
