Well you were right, Kenny points out that there are fresh water
aquatic beds of "grasses", "mosses" and kelp and algae in the next

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 fresh-water underwater plants like these freshwater
"eelgrasses" (different family)

Personally, I won't be trying to map the extent of these underwater
aquatic beds myself, it's enough to tag natural=water for lakes and
waterway=riverbank for river areas, plus the various wetland tags for
areas where the vegetation is above the water level. The presence of
underwater vegetation, like the surface of the riverbed/lakebed, are
much harder to verify and correctly map in most places, unless you
have very clear water and good aerial imagery at the right time of
