How does hay scented fern affect the forest?

• Hay scented fern is very shade tolerant and can grow in almost anywhere in any condition. 

• Once in an area, this fern can dominate a forest significantly affecting long term forest health and sustainability. Hay-scented fern isn't eaten by deer or other native animals.  

• This fern grows in large colonies creating dense shade and thick root systems that make it almost impossible for hardwood seedlings to grow. 
•  The roots also produce biochemical reactions known as an allelopathic effect. An allelopathic effect is a plants way of protecting itself and having a defense against other organisms. 

Identification 

• Easily recognized by strong hay smell when blade is crushed between two fingers or fern is dried.
• Fern stands 1-3 feet.
• Blades are lacy, soft, and hairy.
