The international standardisation of national meteorological networks in the late nineteenth century excluded biotic and abiotic observations from the objects to be henceforth published in the yearbooks. Skilled amateurs being in charge of three meteorological stations in Canton Schaffhausen (Switzerland) and their successors managed to continuously publish phenological observations gathered in the station environment alongside with meteorological data in the official gazette of this Canton from 1876 to 1950, i.e. up to the onset of phenological network observations in Switzerland. At least ten observations are available for 51 plant and animal phenological phases. Long series were assembled (N → = 30) for 14 plant phenological observations, among them for the first flowering of snowdrop (Galanthus nivalis), of hazel (Corylus avellana), of horse chestnut (Aesculus hippocastanum), of winter rye (Secale cereale) and of grape vine (Vitis vinifera) as well as the beginning of hay, winter rye and grape harvesting. Only the bare data were published without any metadata. The quality of 10 long series (N →=60) was checked by investigating the biographical and biological background of key observers and submitting their evidence to graphical (meteorological plausibility check of outliers) and statistical verification. The long term observers, mostly schoolteachers and high school professors, had a good knowledge of botany and the quality of their observations – disregarding obvious printing errors – is surprisingly good. A number of long series (seven) was completed with applicable data from the Swiss Phenological Network up to 2011. Besides anthropogenic shifts (beginning of hay and grape harvest) there is a contrast between a global warming-related earlier flowering of snowdrop and hazel and a later occurrence of grape vine flowering.
