<pre>I have not examined each way for their use in other relationships ... I expect some of them are. </pre>
<pre>In general I would prefer to separate the 'natural' relationships (woods, lakes etc) from administrate ones
simply because any changes to one probably should not change the other.
And it would be easy for a mapper to make a change thinking they were only effecting one feature.
There is a saying 'one feature, one osm entity'? I kind of like that.

<div style="font-family:Arial;">I don't recall that particular
edit but I recall some edits of administrative boundaries,
including national parks and state forests where I was trying to
disentangle landcover from the administrative boundaries, but I
tried to leave the landcover or natural=wood areas as closely as
I could to what I had found. I agree that landuse=forest should
be for commercial forest land use (including state forests) but
should therefore not be used for national parks. If I've made
any errors, please correct them - now and any other instance.
Thanks. <br>

<pre><u>Amalgamation</u>
Looking closely .. for example way 396488797 is used in both relations! So as far as I can see these, in part, are duplicates.
</pre>
<pre>I think these should be amalgamated into one relation.
</pre>
<pre>The outers of this relation should use the greater area of the two original relations.
</pre>
<pre>The inners of this relation should use all inners of the two relations combining where required.
</pre>
<pre>Where there is doubt, bing imagery could be used to resolve and issues.
</pre>
<pre><u>Tags</u>
The source tag could be applied with "source=by down12under using 'aerial imagery later modifications using Bing imagery or as note on the individual way"?
</pre>
<pre>As the areas cover, in part, designated national park/s the tag could be changed to natural=wood as landuse=forest implies the commercial use of the forest (land use).
Aerial or satellite imagery only tells us land cover not land use so I think natural=wood is a better match.
