Mangrove forests are among the most threatened habitats in the world, and mangrove loss is rampant across the globe.

Many of the fish caught commercially in tropical regions reproduce and spend time in the mangroves as juveniles or adults.

Recent research has also indicated that mangroves are incredible carbon sinks, sequestering more carbon than any of their terrestrial counterparts. Mangrove ecosystems are also important habitats for a wide range of birds and insect species, and lesser numbers of mammals and reptile species, providing nesting, feeding, and refuge areas. Explain one probable cause for the change in per capita waste from 2000 to 2012. Even though the full benefits of services provided by healthy, intact mangrove ecosystems are not yet fully understood, recognizing their true economic value may be the only way to strengthen and further spread an existing appreciation for these ecosystems. Mexicoâs mangroves provide ecosystem services that benefit coastal communities and the national economy. And the biodiversity doesn’t end there! These services make it possible for the ecosystems to continue providing services such as food supply, flood regulation, and water purification. Mangrove forests sequester approximately 1.5 metric tons/hectare/yr of carbon, or 3.7 lbs/acre/day of carbon (1336 lbs/acre/yr).

By some estimates, less than 50 percent of the world's mangrove forests were intact at the end of the 20th century, and half of those that remain are in poor condition. Identify one ecosystem service provided by intact mangrove ecosystems. The most classic example is that of mangrove ecosystems, which help reduce the impact of tsunamis. The valuation of ecosystem services is a complex process as it includes several dimensions (ecological, socio-cultural and economic) and not all of these can be quantified in monetary units. Live and decaying mangrove leaves and roots provide nutrients that nourish plankton, algae, fish and shellfish. 392 0 obj

The provision of habitat for aquatic and terrestrial fauna and flora cannot be overlooked. Mangrove substrate may contain 20-25% carbon, which may also help explain the high productivity and biodiversity of these ecosystems. 366 0 obj

nutrient retention and water quality improvement through filtration of sediments and pollutants; Mangroves have been useful in treating effluent, as the plants absorb excess nitrates and phosphates, thereby preventing contamination of nearshore waters. They are dynamic areas, rich in food.
