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.
