virtually unshaded flora and fauna, 2) their 'feet' of concrete slabs resting on the<br />

ground that will resemble loose rocks, and 3) the legs, struts and wiring will provide<br />

possible roost and/or nest sites for some bird species (e.g. Cape Sparrow) and<br />

shelter for some reptiles (e.g. skinks and some geckos).<br />

The effect of shading is difficult to predict, but many bird species seek shade during<br />

the extreme summer heat and may be expected to hide under the tables, at least<br />

around the edges of the layout. An important effect may arise from effects of shading<br />

on the vegetation, altering plant community composition, survivorship and/or<br />

structure.<br />

The effect of the foot slabs is unlikely to differ from that of naturally occurring rocks<br />

(or strewn debris), locally eliminating plant cover but providing cover for small<br />

animals. However, if shallow excavation is necessary to level the ground first and so<br />

alter its soil structure, a slight risk of permanent transformation is expected in the<br />

long term. Given the natural instability of the soil surface under constant strong winds<br />

and/or occasional heavy rains, and the ability of the vegetation to adapt to this<br />

instability may mean the effects are temporary or at least capable of rehabilitation.<br />

The effect of the legs, struts and wiring will depend on how well the design<br />

discourages birds, such as having only vertical and sloping surfaces, and concealing<br />

wiring, to prevent perching and/or nest attachment. Obviously, for operations and<br />

safety, care must be taken to ensure that no living organisms can come into contact<br />

with or entangled by any electrical wiring that might cause short circuits, injury or<br />

death. Since it proposed that sheep graze in and around these PV tables,<br />

presumably the latter factor is already controlled.<br />

• Effect on use and management of water – Water is a scarce and valuable<br />

commodity in this arid landscape and so needs to be managed wisely. Water is used<br />

in an automatic washing system to periodically clean the upper surfaces of the solar<br />

panels on the PV tables. The water runs off into a gutter at the base of the panel<br />

arrays and is then stored for re-cycling. The only effect on fauna would be if residual<br />

water gathers in the drain and attracts birds to drink, or on herpetofauna, especially<br />

frogs is the potential creation of habitat in the form of small artificial wetlands,<br />
