This study aims to assess the spatial distribution and the extensive destruction of mangrove forests in the coastal region Kwandang Gorontalo province. The analytical method used is a map-based spatial analysis the preparation of thematic maps; image interpretation, landform map, the map use / land-use, land units maps, vegetation maps, maps destruction of mangrove forests, and mangrove forest vegetation index maps. This study found that the level of damage of mangrove forests in the coastal areas Kwandang period of 10 years to reach 63%, where changes in forest area of mangroves is caused by pengalihfungsian mangrove areas into embankment land, farms, plantations, settlements, and harbor even based on the analysis of land units in 2010 found that the area that was the area of mangrove vegetation has now changed its designation into a pond with an area of 395.10 hectares, moor or agricultural land area of 179.43 hectares, 156.19 hectares of scrub area, covering an area of 92.24 hectares of rice fields, settlements of 36 , 53 hectares, the port area of 1,904 hectares, and the open land area of 23.89 hectares.

Funsi biologi, merupakan penghasil decomposer, spawning ground atau nursery ground bagi udang, kepiting, kerang, sebagai kawasan berlindung, bersarang, serta berkembang biak bagi burung dan satwa lain, sebagai sumber plasma nutfah, sebagai habitat alami bagi berbagai jenis biota darat dan laut lainnya.
