I have been extremely impressed with the entire Legends & Lairs line from Fantasy Flight Games, and Wildscape fits in nicely. It is a terrific resource for 3e/3.5e outdoor adventures even for casual events, but especially if a group or player wants to build a character around above ground gaming. It contains new ideas and paths for druids and rangers which really expand their roles. New creatures and new terrain features and ways to adapt things. A great - and inexpensive - addition to any library.
