Mangrove ecosystems can be found in tropical and subtropical coastlines. Function of mangroves is preventing sea water intrusion, preventing beach erosion and abrasion, biofilters, as a place to live and coastal food web, create the new island and stabilizing coastal areas. Mangrove should be preserved in order to achieve sustainable ecological functions. The lack of data and information become its own problems in the management of mangrove ecosystems This study aimed to analyses the area and density of the distribution of mangrove in the Mempawah Regency of West Kalimantan Province using NDVI analysis through recording Landsat 5 the recording on 29 June 1989 and Landsat 8 recording on 6 February 2014, found the land area of 250.88 hectares (Ha) of mangrove degraded within that time. Of the total mangrove only 377.25 Ha or 51.02%, which has a high density so as to be maintained and expanded its presence while 362.06 Ha or 48.98 has medium and low density so that needs to be improved through conservation and rehabilitation of mangrove ecosystems.
