Subject Fairview Ecological Assessment – Addendum to Lot 5 WT217 Report

Mr Stannard,

This memorandum relates to the ground-truthing of the proposed development area, as shown in Figure 1.1 and Figure 1.2, and documents the results of ecological investigations of this area.

These ecological investigations were undertaken on 24 July 2012 by two (2) Aurecon ecologists (Vanessa Boettcher and Jenny Grundy).

A report specific to additional proposed development areas within Lot 5 on WT217 has been previously prepared and submitted to Santos (Ecological Assessment Report – Lot 5 Water to Grade Pipelines; Santos Document Reference 0020-GLNG-4-1.3-0030).

This memorandum should be considered as an addendum to the report listed above. This memorandum is specific to the ecology of the proposed development areas shown in Figure 1.1 and Figure 1.2. For ecological information related to the proposed development that is in addition to that covered by this report, please refer to the appropriate Lot-specific report.

1 Ecological Assessment

1.1 General

The proposed development area is situated on undulating hills, with slopes up to 10%. The land has previously been cleared for agriculture practices (including stock grazing) and is adjacent to gas field infrastructure. The majority of the area is dominated by groundcover species with patches of moderately dense regrowth woody vegetation.

No Regional Ecosystems (RE’s) or watercourses are mapped within the proposed development area (Queensland Government 2012). No watercourses were recorded during the site investigation.

No Environmentally Sensitive Areas (ESA’s) are located within the proposed development area. The nearest ESA is a ‘Category C’ ESA situated approximately 850 m in a north north-west direction. This is a ‘Category C’ ESA due to the presence of an ‘of concern’ regional ecosystem. In addition, a ‘Category A’ ESA is situated approximately 1 km to the north of the proposed development area due to the presence of Expedition National Park

1.2 Floristics

The proposed development area has been extensively cleared for agriculture (primarily grazing livestock) and is adjacent to gas field infrastructure. As such, the area is dominated by native pasture grasses, with patchy areas of moderately dense, regrowth woody vegetation. Photo 1.1 and Photo 1.2 are representative of the development area.

The ground cover is dense (approximately 95% cover of the total area assessed) and was dominated by Dichanthium sericeum (Queensland Blue Grass). Pennisetum ciliare (Buffel Grass), Themeda triandra (Kangaroo Grass) and Aristida queenslandicus (Wire Grass) are also present in the ground cover in high densities.

There is no canopy vegetation present through the proposed development area. Woody regrowth vegetation ranges in height from 1 - 7 m, with Eucalyptus melanophloia (Silver Leaved Ironbark), Dodonaea viscosa (Sticky Hopbush) and Eremophila mitchellii (False Sandalwood) the dominant species. Eremophila mitchellii is dominant on the top of the rises, while Dodonaea viscosa is dominant on lower slopes.

Opuntia tomentosa (Velvety Tree Pear) and Opuntia stricta (Prickly Pear), Class 2 Weeds under the Land Protection (Pest and Stock Route Management) Act 2002, were observed in the proposed development area during site investigations.

No flora species of conservation significance (ie ‘endangered’, ‘vulnerable’ and ‘near threatened’ species protected under the provisions of the Nature Conservation Act 1992 [NC Act] and/or ‘critically endangered’, ‘endangered’ or ‘vulnerable’ under the provisions of the Environmental Protection and Biodiversity Conservation Act 1999 [EPBC Act]) were recorded within the proposed development areas.

No Type A restricted plant species are located within the proposed development areas, although it is important to note that a Brachychiton spp. (a Type A species) is located on the boundary of the proposed development area (represented by a yellow asterisk in Figure 1.1 and Figure 1.2).

A list of species recorded in the proposed development area is outlined in Table 2.1 at the end of this document.

1.3 Habitat values

Three (3) incidental fauna species were recorded and identified during the site investigation as listed in Table 1.1. In addition, numerous unidentified bird calls were heard during the site investigation and macropod scats were observed in high densities.

No conservation significant fauna species under the provisions of the EPBC Act and/or the NC Act were recorded during field investigations.

The proposed development area contains areas of moderately dense regrowth vegetation, which provides cover suitable for shelter, foraging and perching. The area connects to similar regrowth vegetation outside the development area and is continuous to the Expedition National Park (a ‘Category A’ ESA area). The proposed development area also contains a moderate amount of woody debris (ie fallen/felled timber), dense groundcover vegetation (ie grassy tussocks) and some leaf litter.

Project 225678 File Santos_Lot_5_WT217_Addendum_Memo.docx 24 August 2012 Revision 0 Page 6

This area is frequently used by macropod species, evident from the high levels of macropod scats on the site.

As a result of the connectivity the regrowth vegetation provides to Expedition National Park, dense grass cover, moderate amount of woody debris and evidence of high use from macropod species, the habitat values of the proposed development area is considered to range from low to moderate.
