Piece of open land (4)

I believe the answer is:

park

(Other definitions for park that I've seen before include "Recreational area - align a car in a bay" , "Leave one's car (in a green space?)" , "One who explored the Niger" , "Area with trees - leave the car" , "Position a car" .)

I've seen this clue in The Independent.
