The Philippines, with the fifth longest coastline in the world, holds at least 50% of known mangrove species and is considered one of the top 15 most mangrove-rich countries. Philippine mangrove forests cover an estimated 2,473.62 km 2 (955.07 sq mi) of coastline as of 2003, which comprise 3% of the total forest cover remaining in the country.
Their loss would be ‘disastrous’, conservationists warned as a global assessment on how mangroves are faring was published. Half the world’s mangroves ‘at risk of collapse’ as climate ...
Mangroves are hardy shrubs and trees that thrive in salt water and have specialised adaptations so they can survive the volatile energies of intertidal zones along marine coasts. A mangrove is a shrub or tree that grows mainly in coastal saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal ...
Why mangroves can be good: They could help protect against sea level rise because their stick-like roots help build up the soil height and their falling leaves decompose into soil.
This decline has led to a negative chain of effects in other ecosystems that are dependent on mangrove forest for survival. [15] In just the last decade, at least 35 percent of the world's mangroves have been destroyed, exceeding the rate of the disappearance of tropical rainforests. [ 16 ]
[106] [107] Likewise, the 2010 update of the World Mangrove Atlas indicated that approximately one fifth of the world's mangrove ecosystems have been lost since 1980, [108] although this rapid loss rate appears to have decreased since 2000 with global losses estimated at between 0.16% and 0.39% annually between 2000 and 2012.

Mangrove ecosystems are found in about 120 countries [8] in the world and make up 0.7% of the world's tropical forests. [7] In most of these regions mangroves provide many services including; shelter, climate regulation through carbon sequestration, [ 7 ] decrease coastal erosion, create a link between terrestrial and marine ecosystems, and ...
Yet, according to UNESCO, some countries lost more than 40% of their mangroves between 1980 and 2005. [4] UNESCO's protection of the mangrove ecosystem involves the inclusion of mangroves in Biosphere Reserves, World Heritage sites and UNESCO Global Geoparks [2] as well as the protection of the blue carbon ecosystem.
