A better analysis of this historic material can provide valuable insights in for instance reference environmental conditions and previous biogeographical distributions of red-list species, nowadays almost extinct due to habitat loss. More efforts should be directed to the conservation, digitisation and study of these historic diatom collections in order to preserve and disclose this valuable knowledge.
