  snow and their own litter

  of snow

Identification methods

• Identification of litter winterers is more
  difficult during winter than in summer,
  especially in case of perennial herbs. We cant
  see leaves, their disposition or shape, or
  flowers. That is why we have to look at other
  characteristics
