Abstract
The mangrove ecosystem is an ecosystem unit in the form of a stretch containing biological natural resources dominated by trees that grow in coastal areas and river estuaries and is influenced by tides. The purpose of this study was to determine the vegetation in Bedono Village, Sayung District, Demak Regency by using remote sensing technology for conservation. Remote sensing technology has recently been used by government agencies or non-government agencies because it is considered more effective and efficient. Based on remote sensing data, the mangrove ecosystem in Bedono Village, Sayung Subdistrict, Demak Regency experienced an increase in the category of moderate and heavy mangroves in 2004-2009.
Highlights
Indonesia is an archipelagic country that has a wealth of abundant natural resources, one of which is mangrove forest
Mangrove forest is a forest that mainly grows on alluvial sludge in coastal areas and tidal estuaries which are influenced by sea tides and consists of Avicennia, Rhizophora, Bruguiera, Ceriops, Sonneratia, Lumnitzera, Excoecaria, Xylocarpus trees, Scyphyphora, and Nypa [4]
In relation to food availability, mangrove ecosystems are places that are rich in food sources for aquatic biota in the form of organic material formed from falling leaves and dirt of land animals which are converted by microorganisms into bioplankton which is needed by marine biota
Summary
Indonesia is an archipelagic country that has a wealth of abundant natural resources, one of which is mangrove forest. The area of mangrove ecosystems in Indonesia reaches 75% of the total Southeast Asian mangroves, and from around 15,900 million ha of existing mangrove forests in the world, around 23% or around 3,489,140.68 ha [1]. The causes of sea level rise can be divided into three factors, namely (a) global (b) regional (c) local. Changes in sea level due to global factors are the main factors that are worrying at the moment because it will cause low coastal plains to be submerged. The impact of sea level rise and climate change will affect a very wide sector in the coastal region. The connection with the existence of mangrove ecosystems is currently threatened by the consequences of climate change, the rise in sea level, exploitation of mangrove forests into firewood and land conversion that causes degraded mangrove forests. This study was conducted to determine the mangrove vegetation on the north coast, Sayung Subdistrict, Demak Regency
