Native Invasive Species: Hay Scented Fern

Dennstaedtia punctilobula
What is a native invasive species? 
  • An indigenous plant that has a habit of rapidly taking over large areas, while crowding out other native species.

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.
