Applies to:
Definition:	Used to indicate if a natural area is actually natural or it is still being managed by humans to keep it in its current state
Statistics:
Rendered as:	No difference in rendering on normal maps, difference can be made on specific editions

Values for managed=*

• no: there is no management of any kind
• yes: landscape or signs indicate management but kind is unclear
  • grazing: herbivores are used to limit the growth of grasses, bushes or trees
  • undergrowth: human interaction to clear (a specific kind of) undergrowth e.g. to preserve lane structures in former estates, eliminate introduced species.
  • mowing: human (mechanical) mowing is done one or more times per year to preserve the open character of the landscape/water

How to map

Add his key to areas already tagged with a natural=* tag that are meant as nature but still require human intervention to keep the natural values they have. An example could be a fell where young trees are removed to prevent the fell from turning into a forest because large grazers are missing in that particular part of nature.

Open questions

• Is this tag limited to "natural" features?
• What about surface=*?
• Objects like leisure=pitch may also need tag to mark their "maintenance" (unlike virtual operator=* company it will mean "real maintaince")
• Does fully specified operator=* imply managed=yes? (probably not, see above)
