A fen is similar to a bog, except a fen gets water not just from rain and snow, but also from groundwater and water running down slopes. Groundwater and water running down slopes bring lots of nutrients, so a fen is able to support more types of plants than a bog.

Common plants, animals, and insects in a fen are:

• grass
• sedge
• rush
• spring peeper
• green snake
• dragonfly
• mosquito
• monarch butterfly
