<p>There are always going to be edge cases that aren't easy to
categorise. There's an area just up the road from where I am
currently that started out as
<a class="moz-txt-link-freetext" href="https://www.openstreetmap.org/way/13866095">https://www.openstreetmap.org/way/13866095</a> in 2007 and has been
continuously refined ever since. The main area's mapped as
natural=heath now (and that's probably as good a bet as any for
what "most of it" is), but there are areas that are wetter than
others and areas that are drier; and areas with more trees and
areas with fewer trees. There are some permanent ponds but many
more "it'll only be wet here N months of the year", where N might
be anything between 2 and 11.<br>
</p>
<p>Any attempt to draw lines between "wood", "wetland" and "water"
is a compromise, and to me it's perfectly understandably to
sometimes have those overlapping (though in the example above it
is something I've tried to avoid).</p>
