Vector map. Area of species distribution and zones of disease severity are shown by polygons.Accuracy of classifier:
Within the limits of the sunflower area two zones of severity of the Root Rot were determined. In the first zone yield losses are low, reaching 10% on the average. This area includes Russia except Northern Caucasus, Ukraine, Moldova, and Kazakhstan. The second is the zone of moderate severity, where yield losses reach 25%. It includes the Northern Caucasus.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 following sources were used to draw the species map: Kukin (1982), Yakutkin (1995, 2001), Antonova et al. (2002).Reference citations:
