An Estimation of Above Ground Tree Biomass of a Mangrove Forest in East Sumatra, Indonesia.

Abstract

Above ground tree biomass was estimated in Bruguiera parviflora, B. sexangula, and Rhizophora apiculata communities of a mangrove forest in Talidendang Besar, East Sumatra, Indonesia. The research was carried out from December 1990 to January 1991, and allometric relation method was used to estimate the above ground biomass of tree species having a diameter of 10 cm and over. The above ground biomass in this forest ranged from 42.94 to 89.68 t d.wt/ha in a B. parviflora community; 75.99 to 279.03 t d.wt/ha in a B. sexangula community; and 40.70 t d.wt/ha in aR. apiculata community.Key words: above !,'Tound biomass / allometric relation method / Bruguiera parviflora / Bruguiera sexangula / EastSumatra /Indonesia / mangrove forest / Rhizophora apiculata / Talidendang Besar. Cintron and Novelli (1984) stated that above ground biomass is the amount of standing organic matter per unit area at a given time, which is related to a function of productivity system, stand age and organic allocation, and exportation strategies. The estimation of above ground biomass not only provides increasingly valuable means for making comparisons among ecosystems as well as for evaluating world wide productivity patterns (Rodin and Bazilevich, 1967), but is also very important for the study of the functional aspects of forests such as primary productivity, nutrient cycling and energy flow (Hasse et al., 1985). Consequently, biomass data is important in order to understand forest ecosystem characteristics to establish the proper management system based upon the sustainable yield principle.Variability in biomass data may be attributable to stand age, stand history, or structural differences (Lugo and Snedaker, 1974), and climatic factors such as temperature and precipitation (Komiyama et al., 1988). The world literature on forest biomass and production expanded rapidly in the 1960s and 1970s. Cannell (1982 reviewed the world forest biomass data from 600 papers which were written by scientists all over the world. However, the papers on the biomass of mangrove forests were scarce. Some researchers who worked on standing biomass of mangrove forests were Golley et al.

“…Dari habitatnya, ekosistem mangrove memiliki tipe habitat berlumpur sampai lumpur dalam (Istomo, 1992dan Aksornkoae, 1993, Hamilton et al, 1984., Krasuss dan Allen. 2003), dipengaruhi oleh pasang dan penggenangan air laut (Hutchings dan Saenger, 1987, Kusmana, 1996, serta Snedeker dan Snedeker, 1984, serta dapat hidup pada kisaran salinitas rendah sampai tinggi (Hutchings dan Saenger, 1987, serta Aksorkonkoae, 1993. Selain kekhasan tersebut, ekosistem mangrove memiliki vegetasi yang memiliki berbagai macam manfaat dan fungsi seperti untuk mengurangi resiko abrasi (Hilmi et al, 2014a), penstabil zona pantai (Mazda et al, 1995), kemampuan untuk meredam gelombang pasang (Mazda et al, 1995dan Massel et al, 1999, resiko tsunami (Hilmi et al, 2014b., Kerr et al, 2006, serta Kathiresan dan Rajendran, 2005, habitat berbagai mikroorganisme (Elison, 2008dan Alfaro, 2006 dan bakteri pengurai, habitat berkembang biak berbagai fauna dan tempat migrasi satwa (Murdiyanto, 2003), mengurangi dan mengakumulasi berbagai bahan pencemar logam berat dann minyak (Wickramasinghe et al, 2009.…”

Aboveground Biomass Production of <i>Rhizophora apiculata</i> Blume in Sarawak Mangrove Forest

“…The estimation of aboveground biomass of mangrove is not only provides increasingly valuable means for making comparisons among ecosystems but could also use to evaluate the productivity pattern, nutrient cycle and energy flow (Kusmana et al, 1992). Furthermore, in order to understand the forest ecosystem characteristics, the measurement of tree biomass is important.…”

Biomass and net primary productivity of mangrove communities along the Oligohaline zone of Sundarbans, Bangladesh

“…This study showed that the mean above-ground biomass of 154.8 Mg•ha −1 was within the documented range of 40.70-279.03 Mg•ha −1 in the mangrove forests of East Sumatra, Indonesia (Kusmana et al 1992), or of 123.5-383.5 Mg•ha −1 in the mangrove forests of Dominican Republic (Sherman et al 2003). The present value of AGB was almost identical to that (159 Mg•ha −1 ) of Rhizophora apiculata Bl.…”
