Apologies for top-posting, but the interface in the browser does not enable me to make any sense of multiple comments. Anyway here goes: Zostera (eel-grass) grows below the tide line, so really is not an emergent plant. Other things in your list of aquatic bed vegetation are also not usually

Well you were right, Kenny points out that there are fresh water aquatic beds of "grasses", "mosses" and kelp and algae in the next email. But we have different tags for saltmarsh and marsh, so I think it is good to have natural=seagrass or wetland=seagrass in addition to some other tags for

Ok, looking at the aerial imagery at https://www.openstreetmap.org/edit#map=16/48.4961/-122.4876 - this is certainly not a reedbed. Reeds have long woody stems which stick up out of the water, and they are a significant barrier to travel. Even wetland=saltmarsh would be inappropriate, because a

Do you have an example of a location which you wish to tag? It looks like eelgrass usually grows below the low tide line, unlike a salt marsh, and the grasses do not usually reach up above the water. So natural=wetland might not be appropriate for these seagrass meadows. Perhaps natural=seagrass

How should eelgrass[1] be tagged? I see that wetland=reedbed [2] has been used in tidal areas mainly in Europe but also in the US but they are two different plants. [1] https://en.wikipedia.org/wiki/Zostera [2] https://en.wikipedia.org/wiki/Reed_bed -- @osm_washington www.snowandsnow.us
