Pristine Mangrove Community in Wondama Gulf, West Papua, Indonesia

Abstract

Papua shoreline has been considered as the most extensive mangrove area in Indonesia and great size of their trees. It implies that the forest could be a perfect habitat for biota food web due to its high productivity. Wondama mangrove, part of Cendrawasih National Park -West Papua, had a promising mangrove forest to be discovered. Nevertheless, the forest was rarely studied due to limited access and costly, so that the scientific data was difficult to be found scientifically. A preliminary study was carried out to identify the condition of mangrove in this area. The objectives of this study was to analyze mangrove community health and structure. Canopy coverage and vegetation structure data were collected from 107 circular plots included three plot areas (radian: 5 m, 2.5 m and 1 m) which were distributed to determine three plant classes i.e. tree, sapling and seedling, respectively. Present study showed that Wondama mangrove is a pristine mangrove community. It had large size of tree trunk diameter by 19.77± 6.55 cm averagely. Its diameter size affected on low tree density which was less than 1000 tree/ha. Those two parameters were strongly negative-correlated each other. On the other hand, community canopy was highly covered mangrove area by 82.46±6.43%. Rhizophora has mostly dominated in the forest. Mangrove regeneration in Wondama was excellent referring to density and species composition of sapling-seedling levels.

Spatial and temporal analysis for mangrove community healthiness in Liki Island, Papua-Indonesia

“…In mangrove forest nearby residences, mangrove canopy coverage was reaching less than 50% due to illegal logging. Some pristine areas in Papua also found the higher mangrove canopy coverage such as in Wondama (82.46%) [32], Rajaampat (84.73%) [33] and Meos Mangguandi-Biak (93.88%) [30]. Another outermost small island in Papua, Miossu Island had a distinctive canopy coverage among zones, where its value in Rhizophoraceae zone reached the highest value at 85.04% [26].…”

Community of Mangrove Category Tree and Sapling in The Sekotong Bay, West Lombok

“…The biggest stem diameter of mangrove tree category was 10,57 cm recorded at transect SKTM04, and the smallest tree diameter (6,10 cm) recorded at transect k SKTM03A. The biggest diameter (10,57 cm) of mangrove tree in the Sekotong Bay is much smaller compared the diameter of naturally mangrove tree of the District of Wondama-Papua (Dharmawan & Widyastuti, 2017). The high and diameter comparison of mangrove tree among transects are given in Figure 4.…”

Struktur Komunitas Dan Kepadatan Moluska Dan Krustasea Di Ekosistem Mangrove, Kabupaten Merauke, Papua

“…Sedangkan di pulau-pulau kecil, mangrove tumbuh pada substrat keras dengan salinitas tinggi, sehingga hanya jenis-jenis mangrove bersifat toleran yang dapat tumbuh (Dharmawan & Pramudji, 2020). Pada kondisi substrat berlumpur, Rhizophora apiculata dan Bruguiera gymnorrhiza merupakan jenisjenis yang tumbuh dominan, sedangkan Sonneratia alba adalah jenis yang dominan tumbuh pada substrat berpasir ataupun berbatu ( Dharmawan & Widyastuti, 2017;Sasmito et al, 2020).…”
