Basic contents:

Vector map. Area of species distribution and zones of disease severity are shown by polygons.

Accuracy of classifier:

Within the species area a zone of disease severity was allocated according to the soil and climatic conditions favoring the fungus development. In this zone the yield losses caused by the Gray Snow Mold can reach 10% (Sidorova, 1973).

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. The following sources were used to determine the area: Ishkova et al. (2002), Sanin (2000). The following sources were used to determine the zone of severity: Potatosova (1960), Kask (1963), Sidorova (1973), Nivik (1975), Sanin (2000). 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.
