Plan quiet enclosure for meadow tree (5,3)

'tree' is the definition.
I know nothing about this answer so I can't judge whether this works.

'plan quiet enclosure for meadow' is the wordplay.
I cannot quite see how this works, but
'plan' could be 'map' (plan can mean a map of something) and 'map' is located in the answer.
'quiet' could be 'sh' (both can be said to tell someone to be quiet) and 'sh' is located in the answer.
'meadow' could be 'lea' (a lea is a grassy area) and 'lea' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
