Parks

The trees in Parks Seasons are placed into parks. A park is an n-square polyomino. Each square of a park can be in 3 basic states: empty, containing a tree, white dot.

Shape and size
"See also: List of parks by shape and size."In one-tree levels, parks can have any number of squares. However in two-tree levels this number is limited to 3 or higher, although not every 3+-omino works, because the tree would touch no matter where they are.
