Data for: A National-scale Dataset of Arable Plant Abundance from Citizen Science Surveys of Swedish Field Margins

The project "Åkerogräsinventeringen" (the inventory of arable plants), done by the Swedsh University of Agricultural Sciences and the Swedish Botanical Society 2020-2023, aimed to map out the occurrences of arable plants in Swedish fields. Here, cleaned and filtered data from the survey is presented. The dataset and the project are thoroughly described in the article "A national-scale dataset of arable plant abundance from citizen science surveys of Swedish field margins" (Note that this article is a data description, and not a study).

Collection method: Volunteers from the Swedish Botanical Society surveyed a 100*1 m transect, along the ploughed part of the field margin. All plants in the transect were noted and their abundance estimated. Fields from all of Sweden were surveyed.
Data cleaning: The data have been checked and errors corrected in communication with the surveyors. In the cases where uncertainties remained, the sites have been removed in this cleaned and filtered version of the dataset.

The excel file consists of two tabs. The first tab provides important information on the proper usage of the data. The second tabs contains the data. The data file consists of 24 columns and 7364 rows. Note that all coordinates are given according to WGS84.
