Details
Data may be freely used for research, study, or teaching, but be cited appropriately (see references below).
This function will download the DEFID2 database to the temporary directory once per session. After it's downloaded, the queries to the database are faster than the first time.
Note that 99.6% of the observations correspond to Picea abies. Also, 99.3% of the observations are in Czechia.
The data comprises over 650,000 georeferenced records, which can be retrieved as points or polygons, representing insects and diseases that occurred between 1963 and 2021 in European Forests.
