This study aims to identify the species of mangrove constituents and determine the zonation of the growing community of mangrove plants from the seaward to the landward zone, of the Nature Conservation Forum (NCF) Putri Menjangan coastal Pejarakan village Buleleng from July to October 2017. Identification of mangrove plant species based on the following characteristics: habitus, root type, fruit shape, inflorescence, leaf shape and leaf arangement. Zoning of mangrove grown is determined from vegetation analysis conducted in 3 zones (front zone, middle zone and back zone) with quadrat method, the area of each square is 20 m x 20 m. Parameters specified in each kwadrat are the density, dominance and frequency of presence of each species. Zoning of mangrove community is determined based on the important value of mangrove plant species. The diversity of the mangrove community is calculated by the Shanon-Wiener Diversity Index. The results of the study identified 13 species of true mangrove plants (mangrove) and 14 mangrove mangrove associates. The dominant species are Sonneratia alba (important value / iv is 98.19), Lumnitzera racemosa (iv. is 40.75), Rhizophora apiculata (iv.is 35.53), Rhizophora mucronata (iv. 33.02), Ceriops decandra (iv.23.61) and Avicennia marina (iv. 22.22). The diversity index of mangrove species (H) is 2.07, then it is considered good. The pattern of growing mangrove plants in coastal Pejarakan Buleleng, in general follow the natural pattern of mangrove zonation. Typical characteristics and patterns of growing mangrove zonation become interesting attractions and reference for mangrove area managers in ecotourism development and efforts to conserve mangrove forests.

<p><em>The objective of this research was to know the structure, composition, potency of mangrove tree and also exploitation of mangrove observation type in Isenebuai Village District Rumberpon Teluk Wondama. Vegetation observation was conducted using line and plot method and the interview technique flourish structure. The result of analyse vegetasi study show that 11 mangrove plant species from 5 families were found.The 11 species are Aegiceras corniculatum, Bruguiera sylindrica, Bruguiera gymnorrhiza, Rhizophora stylosa ,Rhizophora mucronata, Ceriops tagal, Heritiera littoralis, Heritiera globosa, Lumnitzera litorea, Xylocarpus granatum and  Xylocarpus moluccensis. The result also show that local people used 7 mangrove plant species from 4 families for 7 categories of use that are food-stuff, construction material, medicine, energy sources, boat supply, musical instrument and equipments of artistry and furniture.</em></p>

The ant fauna of Australia's tropical rainforests is composed primarily of Indo-Malayan taxa, and is remarkably disjunct from the surrounding savanna ant fauna, which is dominated by autochthonous, arid-adapted species. Mangrove communities, which like the rainforests have closed canopies, are major components of the Australian tropics; however, their ant faunas remain poorly known, despite ants being the dominant insect group in them. This paper describes the ant fauna of a mangrove community in Darwin Harbour, and compares it with the regional savanna and rainforest fauna. Ants were sampled at baits located on the ground, foliage, and tree trunks, along three transects following the elevation/tidal gradient. Sixteen ant species were recorded in mangroves, including three savanna species, six rainforest species (one, Monomorium ?turneri, not previously recorded in Northern Territory), five habitat generalists, and two species restricted to mangroves, Polyrhachis constricta and P. sokolova, which remarkably nest in intertidal sediments and are subject to inundation. Species of Crematogaster and Polyrhachis were most abundant, and Polyrhachis was the richest genus with six species. The biogeographical affinities of the ant fauna were very similar to those of local rainforest faunas, but with a higher incidence (50%) of obligately arboreal species. Five of the Polyrhachis species occurred in distinct zones along the elevational/tidal gradient, thus exhibiting the zonation so characteristic of mangrove plant species, although the ant zonation did not appear to be mediated by floristic changes. Potential causes of this zonation are both abiotic and biotic, but their relative importances remain a matter of conjecture.
