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

Mangroves

The ranges are available as a single data set (File Geodatabase) for most plant species that considered to form part of the mangrove ecosystem.

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.

From the FWS website
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.
