</span>If you are doing manual mapping, I think you can just go ahead and do<br>
whatever you think best and not worry about it too much, but it's of<br>
course nice to ask for opinions as you just did. You don't have the<br>
duty of care that an automated edit has, and Acton doesn't have so many<br>
areas that changing the tags is really hard (an hour or so?).<br>
<br>
I wonder if you have any areas where leisure=nature_reserve does not<br>
apply (Arboretum, arguably) and another leisure= tag also does not apply<br>
(?). I would be curious to see what happens rendering-wise to an area<br>
with boundary=protected_area and no leisure=.<br>
