Bojong Salawe Estuary is one of the areas affected by the tsunami which occurred on July 17, 2006 in Pangandaran Regency. The disaster has caused various forms of damage; one of them being in the mangrove forest area. Rehabilitation activities have been carried out to restore the function of mangrove forests in providing various benefits to the community. This research was conducted to determine the pre- and post-tsunami changes in mangrove land cover, as to determine the mangrove land suitability in areas that have been rehabilitated. Land cover was obtained from the classification of Landsat 7 ETM+ and SPOT-6 images using the on-screen digitizing method. Land cover changes were analyzed through overlaying land cover maps in 2006 (pre and post tsunami), 2011, 2016, and 2021. The mangrove land suitability was analyzed based on the physical condition of the land (distance from rivers, slope, elevation, substrate, and salinity) using the scoring method and weighting. The results showed that after being hit by the tsunami in 2006, the mangrove cover had decreased by 2.49 ha. After rehabilitation procedures were conducted, the mangrove cover has increased by 18.15 ha up to 2021. Most of the study areas have a very suitable category of mangrove suitability (S1) with the total area of 190.74 ha and the rest of the area are categorized as (S2) with the total of 12.57 ha. This indicates the potential for successful mangrove rehabilitation that needs to be carried out continuously in the future.
