Note: This gain is based on a combination of ‘prior management’, ‘security’ and ‘maintenance’<br />

gains available to individual offset sites as identified in the Detailed Ecological Assessment (SMEC<br />

Australia, 2009). ‘Improvement’ gains have only been calculated for HZ10. Prior management and<br />

security gains are not calculated for HZ32 as this site is a public roadside.<br />

*Note: To receive a site condition gain score of 12 points (0.12 Hha), logs within the re-vegetated<br />

area must be meet the benchmark log length, including large logs. For Grassy Woodland, large<br />

logs are 35cm in diameter for Eucalypt spp., 20cm for Allocasuarina spp. and 15cm for Acacia<br />

spp.. The benchmark log length is 15m / 0.1 ha or 150m per hectare.<br />

Complete details of Net Gain calculations and offset management prescriptions can be<br />

found in the <strong>Armstrong</strong> <strong>Creek</strong> <strong>East</strong> <strong>Precinct</strong> Detailed Ecological Assessment Report<br />

(SMEC Australia 2009).<br />
