Hainan Island will plant mangroves to save its wetlands

Hainan, the southern Chinese tropical island, hopes to save its wetlands through a scheme that aims to plant more than 9 square kilometers of mangroves on its low-lying beaches over the next decade.
Water quality in the wetlands has deteriorated, according to a report on Chinese web-portal sina.com, which shows increasingly high levels of nitrogen and phosphorous in lakes and reservoirs.
The mangroves, once planted, will triple the current area covered by mangroves on the island.
Experts say that the principal threat to Hainan’s wetlands come from, among other, the construction of cities, misuse of wetlands, and increases in pollution.
