description: The Dataset for the Fauna et Flora Fennica project - Historical sighting data for 72 animals, plants, and bacteria found in Finland between 1800 and 1969 dataset contains material collected in the Fauna et Flora Fennica research project. The aim of the project was to renew the understanding of species that have inhabited the Finnish region by providing more comprehensive information on the historical occurrence of different species. We have traced this information from Finnish and Swedish newspapers and magazines published in Finland from the 19th century up to the late 1960s, digitized by the National Library of Finland (the amount of the digitized press material by the end of the project was nearly 28 million pages). In addition, historical information has also been sought from issues of Finnish journals Luonnon Tutkija and Suomen Luonto digitized in projects led by Otto Latva, which are not yet available in the digital archive of the National Library of Finland. Both of the above-mentioned journals are Finnish-language natural science magazines that publish articles on biology.

The reason why we have defined the material to cover the period from the 19th century to the 1960s is that the first newspapers and magazines in the Finnish region were not published until the turn of the 18th and 19th centuries, and various observations of nature were not written into them until the 19th century. Our time frame ends in the 1960s, as more effective methods and models for studying species distribution became common in the latter half of the 20th century, and the threat status of species began to be monitored regularly in Finland as early as the 1980s.

Furthermore, in our two-year research project, we have not been able to examine the historical distribution data for all organisms found in Finland, as the digitised press material provides far too much information to process in two years. There are over 40,000 species living in Finland, and even if we exclude fungi, bacteria and viruses, as well as those that only have a Latin scientific name, there are still 13,782 animal and plant species left. For this reason, we selected 80 species for the Fauna et Flora Fennica project that are known to have undergone changes in their distribution or that are classified as rare, endangered, newcomer or invasive in Finland. We also wanted to examine species that have caused debate or conflict either now or in the past. In addition, we selected some species for examination based on suggestions from biologists who were partners in the project.

Of all 80 species examined in the Fauna et Flora Fennica project, we were able to compile datasets containing geospatial data for a total of 72 different species. It must be emphasized that these contain sightings recorded in the press, often made by ordinary people. Among them, of course, there are also more formal observations published by natural scientists. The development of the press also influenced which species sightings were made public through the press. In the northernmost parts of Finland, for instance, the first newspapers were not established before the very end of the 19th century. It was therefore not possible to publish species sightings as comprehensively in newspapers in the 19th century as it was in the 20th century, when the number of newspapers and magazines in Finland began to grow rapidly. In addition, the press often considered only unusual species observations, or those of species that significantly affected people’s everyday lives, to be worth reporting. Therefore, by no means all of the species sightings made by people living in the Finnish region from the 19th century to the 1960s ended up in newspapers and magazines. People also reported far more frequently on mammals and birds, while sightings concerning, for example, insects, arachnids, or plants appear far less often in the press material.

The material was collected in the Fauna et Flora Fennica research project funded by the Alfred Kordelin Foundation in 2023–2025, and based on it, among other things, the openly accessible work Suomalaisten lajien historiallinen kartasto (In English: Historical Atlas of Finnish Species) (2025) has been published: https://edition.fi/thy/catalog/book/1176. For this book, we have created distribution maps for different species using the geospatial data contained in these CSV files.

CSV files contain 9 columns with the following information in order: 



Year of sighting

Location (the exact location of the observation, e.g., name of village or body of water)

Description of the location (tells whether the location is, for example, a lake or river, or which city or municipality the location of the sighting belongs to)

Press source and publication date

URL (digital press sources are available to everyone until the 1940s. To view more recent press material, you need to have credentials from a Finnish university or research institute)

Latitude

Longitude

Geodetic system

Notes


Below is a list of all 72 species with their English, Finnish, and Latin names, as well as the names of everyone who participated in collecting observation data for each species. The species are divided as follows: Mammals (CSV files 1–15), Birds (CSV files 15–37), Reptiles and amphibians (CSV files 38–45), Fishes (CSV files 46–50), Molluscs, annelids, algae and bacteria (CSV files 51–54), Woody plants (CSV files 55–63) and Herbaceous plants (CSV files 64–72)



Note: Historical distribution data is available for all species except moose and whooper swans for the entire time period. We only collected distribution data for moose and whooper swans from the 19th century, as the data for these species became too extensive in the 20th century.
