I never claimed it to be. What i did say is that what is mapped with <br>
barrier=hedge on polygons with a different meaning than 'this polygon <br>
is enclosed by a hedge' is elsewhere predominantly mapped with <br>
natural=scrub/wood or landuse=forest. I demonstrated this with links <br>
to various places.<br>
<br>
Introducing a secondary tag to natural=scrub/wood and landuse=forest <br>
(like barrier=yes) indicating that it is impassible without difficulty <br>
would be a good idea</blockquote><div><br></div><div>Not so good an idea. A hedge area differs from natural=scrub/wood</div><div>or landuse=forest in at least one way, other than just by being impassable.</div><div>There is the matter of height. Although newly-planted trees may be shorter</div><div>than a typical hedge, those trees will soon be much taller than the hedge</div><div>but the hedge will be maintained at a lower height.
