Mangrove Bio-Ecology for Rehabilitation Purposes in Pandeglang

Abstract

Abstract This study aims to determine the bio-ecological condition of mangroves that could be considered for the rehabilitation planning process by the government or any other entities. This study was conducted in Ciseukeut-Panimbang, Pandeglang. Eight mangrove species were found, which belongs to four families of Avicenniaceae, Myrsinaceae, Euphorbiaceae, and Rhizophoraceae. The density of mangrove species in the study site ranges from 113-744 ind/ha. The results of the diversity index value showed that mangrove vegetation was in the low category with a range of 0.04 – 0.16. This value indicates the presence of environmental pressures, so the mangrove ecosystem is considered unstable. The dominance index belongs to the low category with a range of 0.03 - 0.23. The uniformity index value is also low at 0.01-0.08. The value shows that the mangrove ecosystem in Ciseukeut Panimbang Village is experiencing pressure, or its condition has decreased. Efforts to rehabilitate mangroves in Panimbang regency can be done by planting from the dominant mangroves Avicennia sp and Rhizophora sp. These species play a very important role in Panimbang, its important value index was 90,66% and 56,77%. The timing of planting propagules in Pandeglang area should be carried out in the eastern season so that the propagule can grow optimally and safely inundate from tides that occur in the western season with a height of up to 1 m.
