I am looking to map out the salt marshes, mangroves, and tidal flats of the world, but I am having difficulty finding data for this. Does anyone have any such data? This is for a research project at my university. Thanks
File Geodatabase of Mangroves here
The ranges are available as a single data set (File Geodatabase) for most plant species that considered to form part of the mangrove ecosystem.
Mangroves (zip file, 97.8 MB)
See metadata document for further information.
I believe those are also available in the National Wetland invnetory.
Managed by U.S Fish and Wildlife.
Perhaps not broken out quite like you mentioned.
This legend shows Vegetated and non-vegetated brackish and saltwater marsh, shrubs, beach, bar, shoal or flat all together.
And this code chart shows how to break out class-subclass and modifiers.
And even an area to contribute data.
Koordinates.com are usually great with these things.
For example, here's one for the whole of New Zealand.
This database does it for mangrove globally for 2012 inclining percentage mangrove cover at the 30 m pixel level.
This is the URL to the paper and below is the data link.
and this one has year 2000 presence and absence globally.
The IUCN Redlist link above is not actually a true mangrove location but a potential species region DB.
