in difficulty meeting<br />
peak irrigation<br />
efficiency.<br />
61 (Strategic Water<br />
Plan)<br />
At RBG Melbourne, compliance with all<br />
water management targets including:<br />
– Co<strong>mb</strong>ined annual aggregate of<br />
rainfall/irrigation less than 900 mm<br />
– <strong>Annual</strong> water use less than 90 litres<br />
(L)/visitor<br />
– Irrigation Index equal to or less than 1<br />
At RBG Cranbourne:<br />
– the first phase of the review of front<br />
entrance plantings completed and<br />
converted to non-irrigated landscape<br />
using ornamental native/indigenous<br />
plants<br />
– installation of an automated weather<br />
station linked to irrigation scheduling,<br />
including staff training and monitoring<br />
RBG Melbourne continued to strive to<br />
meet water management compliance<br />
targets, as outlined below:<br />
– <strong>Annual</strong> rainfall/irrigation aggregate was<br />
1,090 mm, exceeding the original target;<br />
conversely, only 40ML was used for<br />
irrigation compared with 120ML for<br />
2009–10<br />
– Total <strong>Annual</strong> Water Use Visitation Index<br />
was estimated at 32 litres/visitor/annum<br />
– Irrigation Index was 1.03 or 3 per cent*<br />
over estimated requirement.<br />
At RBG Cranbourne, the following water<br />
managements initiatives were<br />
implemented:<br />
– 4,000 Banksia blechnifolia and 800<br />
Lomandra longifolia were planted at the<br />
front entrance in Nove<strong>mb</strong>er <strong>2010</strong>, with<br />
the entire area re-mulched post planting<br />
– an automated weather station was<br />
purchased; installation is pending<br />
handover of the relevant Australian<br />
