Facts about Mangroves
- 10
Mangrove forests generate approximately 400 kilograms of leaf litter per hectare annually, which decomposes to form nutrient-rich detritus that supports entire food webs in coastal ecosystems.
- 09
In 2022, Indonesia lost approximately 23 percent of its remaining mangrove forests over the previous two decades, primarily to aquaculture and agricultural expansion.
- 08
The intricate prop root systems of mangroves can extend up to 10 meters horizontally, creating natural barriers that reduce wave energy and protect coastlines from storm surge and erosion.
- 07
Aerial roots of mangroves can absorb oxygen directly from the air, allowing trees to thrive in anaerobic mud where most plants cannot survive.
- 06
Mangrove forests provide nursery habitat for over 80 percent of commercially harvested fish species in tropical and subtropical regions.
- 05
Mangrove trees can survive in soil with salinity levels up to 90 parts per thousand, nearly three times saltier than open ocean water.
- 04
Half of all mangrove forests that existed in 1980 have been destroyed, with current loss rates reaching 1 percent annually across tropical regions worldwide.
- 03
Approximately 118 species of fish depend on mangrove nurseries in Southeast Asia before migrating to open ocean waters as adults.
- 02
During high tides, mangrove root systems filter out 90 percent of salt from seawater through specialized glands on their leaves.
- 01
Four times more carbon per hectare than tropical forests is stored in mangrove ecosystems, making them critical for climate regulation.
