The specific location of the 1 ha survey sites were selected on the basis that they were situated in large contiguous areas that were considered typical or characteristic of the respective vegetation management strategy. Within each property, sites are generally a minimum of 1 km apart but may be within 500 m of one another in some cases. At the property scale, sites are spread across a 10-15 km radius on each property. Sites are located a minimum of 500 m from any water point, commonly 50-100 m from the nearest access track and that the demarcation used for site selection within the “Unmodified vegetation management” class (30-45% vs. 45-60% canopy cover), was made using crown canopy mapping based on 1996 1:250 000 aerial photography. Sites are broadly situated within the same broad Ironbark woodland community (Eucalyptus whitei, E. melanophloia). Two Queensland land zones are mapped across the four properties with sandy plains and alluvial systems each represented by two properties. One of the leaseholders (with five thinned and five unmodified sites), withdrew from the study following the July 2008 survey leaving 50 sites distributed across three leasehold properties remaining in the study.
