Missing playground equipment.
If you are nearby, could you check what is here?
You're welcome to add it yourself! :-)

Verify details, survey needed.

Missing details for orchard; local knowledge needed.
It may be useful to describe the type of trees and add any (information from) signs if present.

Note, forest/wood in development inside existing area of forest/wood is likely scrub, not orchard('intentional planting of trees or shrubs maintained for food production'), or plant nursery (for plant production).
