CHANGES IN DENSITY OF MANGROVE FOREST IN NUSA LEMBONGAN, BALI
Mangrove forest in Sub district of Nusa Penida is mostly concentrated in the northern side of Nusa Lembongan. The area is part of Nusa Penida Marine Protected Area. This research was undertaken in Nusa Lembongan on July 2010 and aims to provide information on changes in density and coverage area of mangrove forest in 2007 and 2009 and to give the scientific recommendation for the local government to support managing the mangrove forest, especially in Nusa Lembongan, Bali. The method used for primary data collection is PCQM (Point Center Quarter Method). The ground truth includes 15 transect sampling locations for which mangrove vegetation parameters have been estimated using that method. Imagery data that used to estimate the density of the mangrove of Nusa Lembongan is ALOS AVNIR-2 (Advanced Land Observing Satellite), acquired on November 14, 2007 and April 3, 2009. The result is there was a reduction in mangrove coverage in Nusa Lembongan of 47, 09 ha in the period of 2 years (2007-2009). Base on NDVI values, the density of mangrove forest in Nusa Lembongan classified into 5 classes, namely very dense, dense, medium, rare, and very rare. Generally, the condition of mangrove forests in Nusa Lembongan is still in good condition because the area with dense-class and very dense-class was still wider than the other density classes.
