There has been much uncertainty about the extent of mangroves left remaining in the World, as result of this the ITTO commissioned a revised World Atlas of Mangroves, this was published in 2010 by Earthscan and contains the most update information of the state of mangroves today.
A report by International Union for Conservation of Nature ( IUCN ), last found that more than 1 in 6 mangroves are endangered, placing 16% of mangrove species on the IUCN Red list. The full article can be found here: Mangrove forests in worldwide decline.
Also last year several articles have appeared on the rate of decline of mangroves, one of them is this nice brief article published by Our Amazing Planet last year.
