Vector map. Area of species distribution and zones of disease severity are shown by polygons.Accuracy of classifier:
The area is divided into zones of high (epiphytotic every 5th year) and medium (epiphytotic every 10th year) harm.Method of map production:
Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature, species distribution was hand drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map (Koroljeva et al., 2003). Hand drawn maps were scanned, georeferenced and vectorized. The map of Trushko & Rumyantseva (1971) was used as a base and adjusted according to Transhel (1939). The borders of the two zones of harm were determined according to Trushko & Rumyantseva (1971).Reference citations:
