I think what's happening here is one mapper "colouring in" without any 
particular knowledge of the area.  Whilst adding the results of some 
mapping in South Wals I came across a number of heath landuse polygons 
south of Talybont that bore almost no resemblance to on-the-ground 
features - it didn't align with existing walls, or woodland, or anything 
to better than 100m in cases.  They've been contacted a couple of times 
about it, and haven't replied, so with a DWG hat on I sent them 
http://www.openstreetmap.org/user_blocks/1104 which was intended to 
improve mapping quality and responsiveness. The former has happened (a 
bit); the latter not so much.

If all the places that were originally added as natural=heath by this 
mapper were removed I don't think we'd have a significantly worse map, 
and it'd be easier to map these features properly.

There will be occasions where people have fixed up significant portions 
of this mappers work, and it'd be great to keep that (there's a massive 
"heath" http://www.openstreetmap.org/way/456253921 between Merthyr and 
Crickhowell that I've tidied the Talybont side of - but unfortunately 
that's only 20% of this one object - I'd be surprised if it is Heath at 
http://www.openstreetmap.org/way/456253921#map=17/51.76532/-3.33642&layers=H 
for example), but maybe the solution there is to slice away the parts 
with nodes added by this mapper from the parts with nodes added by others?

Best Regards,

Andy
