Like all of Mr. Babble's sets, this is reminiscent of the old-school Dungeon Floor Plans. (In fact, some of the pages look like they would fit right into some of the forest sets.)
What you get are pages of assorted foliage in different hues (and pages of B&W so you can color them yourself) and some grassy pages as well. The detail is excellent, and overall this is a simple, but useful set. And the price is good too.
