Hedges can certainly be areas, some can be a few metres thick.<br />
<br />
A common mapping scenario is a thick hedge and a stile at each side. The only way to represent this is to map as an area and map the stiles as nodes connected to the outline.<br />

Hedges and walls are linear in nature, not an area.</p>

<div>Currently, barrier=block is not allowed to be mapped as an area. As blocks can be big enough to map them as areas, I think it should be allowed, the same as in barrier=wall or barrier=hedge. Anyway, currently we have 3,9k of barrier=block areas in database.</div><div><br /></div><div><a href="https://wiki.openstreetmap.org/wiki/Tag%3Abarrier%3Dblock">https://wiki.openstreetmap.org/wiki/Tag%3Abarrier%3Dblock</a></div><div><br /></div><div>Block examples:</div><div><a href="http://www.concrete-barriers-blocks.co.uk/up/concrete-barrier-type-m-block-photo.gif">http://www.concrete-barriers-blocks.co.uk/up/concrete-barrier-type-m-block-photo.gif</a></div><div><a href="http://cdn1.codziennypoznan.pl/201606241325/pub/img/full/71/1c58d-a9.jpg">http://cdn1.codziennypoznan.pl/201606241325/pub/img/full/71/1c58d-a9.jpg</a></div><div><br /></div><div>Barriers with mapping as area allowed</div><a href="https://wiki.openstreetmap.org/wiki/Tag:barrier=wall">https://wiki.openstreetmap.org/wiki/Tag:barrier=wall</a>
