Swedish National Forest Inventory
Sweden for the last 100 years has been systematically collecting and storing data to create an updated inventory of its forests. An extensive network of permanent plots with a size of 154 m2 is used for the forest inventory . For this project, I drew a subset of the official data by downloading the readily available file from the webpage of the Swedish University of Agricultural Sciences (https://www.slu.se/nfi) and filtering in data from the 2022 field survey . The presence and absence of pine trees were extracted from these data along with the geographical coordinates of the plot. This data extraction yielded a total of 2,356 data points. This dataset is referred to as NFI.
