“…Information regarding forest structure and the species composition of mangrove forests is fundamental for sustainable mangrove forest management and the conservation of mangrove forest resources. Forest structure generally can be determined from three components, such as abundance which is determined by the number of species and individuals per species, vertical structure/stratification (tree height distribution), and horizontal structure (basal diameter distribution of the trunk) (Kershaw 1964;Domínguez-Cadena et al 2016;Prisambodo et al 2019). The structure and species composition of the mangrove forest community is strongly influenced by not only climatic factors but also site factors, such as topography, soil characteristics, and tides of seawater (Eddy et al 2019;Azman et al 2021).…”

Abstract. Rumondang AL, Kusmana C, Budi SW. 2021. Species composition and structure of Angke Kapuk Mangrove Protected Forest, Jakarta, Indonesia. Biodiversitas 22: 3863-3871. Angke Kapuk Mangrove Protected Forest (AKMPF) is one of the protected forests in the coastal area of DKI Jakarta, Indonesia. This area is important for the north coast of Jakarta, hence it has function to protect the land from sea abrasion, seawater intrusion, and seawater flooding. This study aims to determine the condition of forest structures and species composition in the Angke Kapuk Mangrove Protected Forest (AKMPF) to obtain useful information for sustainable mangrove forest management. Vegetation data were collected using the sampling unit of transect for tree and line plot for forest regeneration inventories. Those data were analyzed for the density, frequency, dominance, species diversity, and species distribution pattern. The obtained results show that AKMPF consists of 13 mangrove species, including 7 species of true mangrove, 5 species associated mangrove, and 1 species of palm, with the dominant species, are Avicennia marina for tree with its regenerations and Acrostichum aureum for groundcover. Overall, the species diversity index in this area was classified as low category. Mangrove trees in this area have height class between 4-28 meters formed bell-curve, while stem diameter class were between 10.00-69.75 cm formed L-curve. The distribution pattern of species in this areal generally was clumped.

“…La estructura de los manglares se integra por un conjunto de variables tales como la riqueza y dominancia de especies, densidad, altura y área basal, que definen los atributos ecológicos de la comunidad (Cintrón & Schaeffer, 1984;Ramos-Durón, Quiróz-Flores, Ramírez García-Armora, & Lot-Helgueras, 2004). Se ha demostrado que los patrones de heterogeneidad estructural en una comunidad de mangles se relacionan estrechamente con procesos geomorfológicos ocurridos durante el Holoceno (Domínguez-Cadena, Riosmena-Rodríguez, & León-de la Luz, 2016;González-Zamorano, Lluch-Cota, & Nava-Sánchez, 2013;Torrescano & Islebe, 2006). Cada especie se adapta de forma diferente a las condiciones ambientales impuestas por la geomorfología, ocupando una zona fisiológicamente óptima en un gradiente ambiental, lo que a nivel de comunidad implica el desarrollo de características particulares de fisiografía, estructura y composición (López-Portillo & Ezcurra, 1989;Lugo & Snedaker, 1974;Méndez-Linares, López-Portillo, Hernández-Santana, Ortiz-Pérez, & Oropeza-Orozco, 2007).…”

impact. The goal of this study was to analyze the mangrove groups, including their structure and dominance pattern under the influence of eight environmental factors (salinity, flood level, pH, air temperature, soil temperature, relative humidity, and content of organic matter 0-30 cm, 0-60 cm). The characteristic physical features and caused by the impact were described for each group. Mangrove structure was evaluated considering a forest inventory conducted in 40 sampling units (300 m 2). Density of live and standing dead trees, stumps and seedlings was estimated for 1ha. The dominance for each species was determined using the relative Importance Value. The identification of groups was carried out with ordination and classification routines. The species with the highest Importance Values were Rhizophora mangle (29.68%) and Laguncularia racemosa (27.33%). Comparatively, the general structure of mangroves in Soconusco in terms of density (2 792 steams ha-1), basal area (36.5 m 2 ha-1) and height (15.5 m) is greater than in other areas of the Mexican Pacific coast. Classification of vegetation data, based on the Relative Importance Value Index, defined five mangrove groups. Outstanding is the presence of a community dominated by Pachira aquatica. The highest density of trees and stumps was recorded in Conocarpus erectus grouping, while the highest density of seedlings was in Avicennia germinans grouping. 86.3% of sampled trees present ≤ 17.7cm diameter at breast height. The variables that correlate significantly with the axis 2 of the ordination biplot were organic matter (30-60 cm), salinity and flood level. Canonical Discriminant Analysis corroborated the differences between mangrove groups, with the first two canonical axes explaining 89.05% of the variation in the data. The community composition varied associated with physical and environmental conditions, and were structurally defined by basal area, crown diameter, height and density, as well as by factors that can be associated with an anthropic impact such as stump and seedling densities. It is recommended to consider the characteristics of each mangrove group to plan their management.

“…Appendix 1 provides further details for species. The geomorphology and maturity of wetland environments influences the average salinity of tidal channels and soil microtopography, in addition to the amount of space available for colonization [13,51,62]. We therefore examined the diversity of the Pacific coastal wetland species in barrier lagoons with normal marine salinity compared to the estuaries that are hypersaline in this arid climatic region (Figures 13A and B).…”

The location and topography of the 1,300 km Baja California peninsula west of the Sonoran Desert provide the most extreme conditions for mangrove forest growth in the Northern Hemisphere. Despite their small size, however, the dwarf shrub mangroves (<2 to 4 m) are important for global CO2 sequestration, and monitoring of their expansion or decline is needed as part of assessing global carbon fluxes and biodiversity. Mangrove distributions at 42 coastal sites in 1972/73 are compared to historical accounts and modern data. These data show that there has been almost no northward migration of Rhizophora mangle during the past century although Avicennia germinans and Laguncularia racemosa have spread north on the Gulf Coast. The dwarf mangrove plant biodiversity in 1972/73 is related to geoform, temperature (T) and seasonal precipitation (P), but mangrove species cluster by annual P and T. The present northernmost Baja California mangrove limits are at 26.79° N on the Pacific Coast, and at 29.04° N on the Gulf Coast mainland, close to limits recorded in 1921. However, there are notable (46 to 4,649 ha) increases in areal cover and canopy height at these northern sites, and in other areas remote from urbanization. Case histories for seven locations point to increasing frequency and severity of tropical storms as main drivers of change on both coasts. However, anthropogenic changes from tourism promotion are major hazards to survival of the Gulf Coast forests, despite international, governmental and public efforts to legislate nature preserves. On the Pacific Coast, rising seawater temperatures may create coastal current conditions that potentially allow the extension of red and white mangrove ranges into northwestern Baja California. However, hazards associated with ocean warming that promotes tropical storm frequency and intensity can have predominantly negative impacts on mangrove production. These extreme hazards counteract the benefits of local and regional protection and management efforts
