Fig. 1 (Updated from the 1960-93 map) Spatial distribution of rangeland grasshopper outbreaks in Wyoming from 1944 to 1996

Fig. 1 (Updated from the 1960-93 map) Spatial distribution of rangeland grasshopper outbreaks in Wyoming from 1944 to 1996, with no data for 1982, 1983 or 1984 (Schell 1994). White = no recorded infestations; gray = 1-2 yr infested; blue = 3-4 yr infested; green = 5-6 yr infested; orange = 7-8 yr infested; red = 9-11 yr infested; yellow = 12-15 yr infested; light yellow = 16-21 yr infested; black = state and county borders.
