More shoreweed by nature restoration
Posted on September 20, 2012
The nature restoration project by the Forestry Department on Texel has resulted in new growth areas for the rare shoreweed. Work at the Korverskooi, De Nederlanden and at the Boet van Hopman made new habitat for this species. Shoreweed is a member of the plantain family. The narrow leaves are typically in dense rosettes.
