Table 1 Natural distribution and range of climatic conditions of the four blue gum species in Australia extracted from Boland et al., ( 1992 )

Species	Latitude range (°S)	Elevation (m)	Min. Mean coldest month, (°C)	Max. Mean hottest month, (°C)	Mean annual rainfall (mm)	Distribution of rainfall¹	Number of frosts per year
E. maidenii	34.7 – 37.5	200 – 900	-4 – +2	+23 – +27	800 – 1200	U	20 – 80
E. globulus	38.5 – 43.5	0 – 450	-0 – +8	+20 – +23	600 – 1400	WS	5 – 40
E. bicostata	31.0 – 38.0	0 – 1050	-2 – +5	+25 – +32	700 – 1200	WS south, U north	25 – 70
E. pseudoglobulus	37.0 – 40.0	0 – 100	+2 – +4	+24 – +27	700 – 1100	slight WS	1 – 15

¹ WS = most rainfall in winter and spring, U = seasonal rainfall uniformly distributed.
