DURING the last half-century, remarkable changes have taken place in the semiarid lands of the southern portion of Western Australia. Millions of acres of country, once covered by an intricate pattern of hardy woodland, scrub and heath have been converted to productive arable land or pasture. With the widespread clearing and cultivation of vast areas, the correction of soil deficiencies by the application of fertilisers, and the sowing of cereals and annual pasture plants, many of the differences in soil types which were very obvious in the original landscape have now been obscured—adding greatly to the difficulties of successful tree establishment.
