Since the moisture factor was the first bioclimatic variable examined, the average yearly rainfall isohyets for the period 1981-2010 were observed.
In our analysis, we have adopted the 500 and 900 mm annual rainfall isohyets as the lower and upper limits for the HRZ in south-eastern Australia.
These regions, as defined approximately by above and below the 1600 mm annual rainfall isohyet, were formed into two zones.

The southeastern ones extend inland to about the 19.7-in (500 mm) isohyet (i.e., they grow where annual rainfall is above 19.7 in [500 mm]), and as isolated patches in appropriate environments, such as gallery forests even in areas where average annual rainfall barely reaches 11.8 in (300 mm).
In the 1860s, South Australians had been advised not to farm north of Goyder line, an isohyet that separated arable land from semi desert.
We transferred the isohyet of lowest value encompassing all populations from an average annual precipitation map (U.S.D.A.
For some soil property surfaces, especially those strongly explained by rainfall, good modelling diagnostics were achieved, but 'unrealistic' mapping artefacts were produced; that is, a sharp change in the continuous attribute was evident at the boundary of a rainfall isohyet. This was caused by: (i) the strongly evident west-east trend in mean annual rainfall; (ii) the relatively sharp change in rainfall with respect to distance, due to the rain-shadow effects of the central plateau; (iii) the strong influence of rainfall on Tasmanian soil formation; and (iv) the data-partitioning effects of the regression-tree approach.
The 300-mm isohyet, defining the strength of the monsoon system, stretched from northern Senegal to central Chad along the 15[degrees]N latitude band.
Further inland the Kalahari thirst-land, far removed from true desert, is bisected by an annual isohyet in excess of 300mm.

The Ziguinchor and Kolda regions are located below the 750 mm isohyet ([approximately equal to]13[degrees]30'N in Senegal; Figure), the southern limit of the reported geographic distribution of O.
