Bedul Mangrove Forest, located in the location of the Alas Purwo Banyuwangi National Park (TNAP). In 2009, the mangrove forest was opened as a tourist area. Although the surrounding community no longer cuts down mangroves, the presence of tourists will affect mangrove growth. This study aims to see the right way to identify mangrove areas, see the dynamics of mangrove trends in TNAP, and adapt it to tourism developments. Remote sensing uses Landsat 8 OLI TRS and Landsat 7 ETM + imagery data for 2005-2020. The mangrove density analysis used NDVI, grouped into 5 classes, from very dense to very rare. The results showed that the mangrove area’s total area was 16.47 km 2 and was stagnant until the time of determining tourist attractions in 2009. Since the determination until 2020, the mangrove area has decreased to 14.96 km 2 . Overall, mangroves’ tendency to experience negative is indicated by an increase in the very dense density class and a decrease in other classes. The composition of mangroves has dramatically increased from 2005 to 2020, from 64% to 87% of the entire class.
