Choropleth map showing the estimated true prevalence of hare treponematosis in brown hares in Czech Republic districts, 2015 to 2017. Superimposed on each plot are points showing the number of hares sampled in villages within each district. Districts with 20 or more samples were merged into four regions differing in altitude median (group 1: Břeclav + Hodonín, 206 m above sea level; group 2: Svitavy + Ústí nad Orlicí, 348 m above sea level; group 3: Pelhřimov + Tábor, 495 m above sea level; group 4: Havlíčkův Brod + Žďár nad Sázavou, 522 m above sea level). The depicted map was prepared in open source geographic information system QGIS by the authors of this study
