It gathers specific actions relevant for the conservation of natural history objects, the coordinated digitisation of associated data and the development of a modern digital infrastructure. This handbook should facilitate the long-term utilisation of Swiss natural history collections data for science and society.

The herbarium presented here was compiled between 1891 and 1924 by the two amateur botanists Alfred Keller and Otto Naegeli, and comprises in total some 130 000 preserved plants from more than 50 000 collections of vascular plants mainly from Switzerland. During ten collection stays for several weeks between 1907 and 1923 Alfred Keller compiled a herbarium documentation of the flora of the Saastal Valley (Valais, Switzerland), which included some 766 species and close to 260 additional varieties and deviating forms («Abnormitäten»), all of them represented with several plants from different localities.
