Poison Ivy
If you are working in a wooded area, you want to be on the lookout for poison ivy. It is everywhere in the United States except Hawaii and Alaska. In the East, Midwest, and the South, it grows as a vine. In the Northern and Western United States, it grows as a shrub. Each leaf has three leaflets. Leaves are green in the summer and red in the fall. In the late summer and fall, white berries may grow from the stems.
