In the Pacific Northwest there are numerous opportunities to go hiking and camping, and generally just being outside in nature.  This non-fiction picture book does a great job in explaining the characteristics of poison ivy and how it can affect humans.  The part that stuck with me, personally, was the fact that burning it and inhaling the smoke can be fatal.  The students to whom I read the book were riveted and really paid attention to it.  Although the illustrations were beautiful and highly detailed, I wish there would have been actual photos of the plant available.  This book should be a first purchase for all libraries in cities where poison ivy grows.
