nearby Signal Station is still strong.

The landmark qualities are also reinforced through the design on the ground. The institutional perimeter fencing; the inherent and still-evident symmetry around the lighthouse; the elevated position of the compound; and the non-axial points of arrival to the lighthouse all contribute to the landmark presence of the site. See Figure 4.

6.3. Natural Values

Flora
Most of the Lightstation and its surrounds was progressively cleared of native vegetation from 1791 onwards; subsequent development and landfilling further reduced habitat for native flora and fauna. The mowed grassland is low in floristic diversity, however patches of regenerating coastal sandstone heath and scrub are found on the lower slopes, sandstone outcrops and along the cliff edge east of the Light Station. Regenerating species include Banksia integrifolia (Coastal Banksia), Banksia ericifolia (Heath Banksia), Leptospermum laevigatum (Coastal Tea Tree), Acacia longifolia var. sophorae (Coastal Wattle) and Kunzea ambigua (Tick Bush). In boggy areas clumps of the native sedge Ficinia nodosus and the rush Juncus usitatus are typically found. Natural regeneration is suppressed in areas that are regularly slashed and where weed species have become dominant.

South-east of the Lightstation, an ephemeral wetland habitat has resulted from the excavation of the sandstone quarry. The quarry receives stormwater runoff and has been partially filled with sediment and building waste. Bush regeneration works have been carried out by Woollahra Council in this area with the aim of removing weed species while retaining habitat for native birds and frogs.

The former sandstone quarry receives stormwater runoff from pipes and surface flow from hard surfaces above and has been partially filled with sediment and building waste. The quarry contains a mixture of planted and self-seeded native tree species including Banksia integrifolia (Coastal Banksia), Casuarina cunninghamiana (River She-Oak), Eucalyptus robusta (Swamp Mahogany), and Melaleuca armillaris (Bracelet Honeymyrtle). The area also contains a number of introduced weed species, including Ipomea cairica (Coastal Morning Glory), Hydrocotyle bonariensis (Kurnell Curse), Delairea odorata (Cape Ivy) and Parietaria judaica (Asthma Weed). Bush regeneration works have been carried out by the Harbour Trust in this area with the aim of removing weed species while retaining habitat for native birds and frogs.

An area alongside the Coastal Walkway has been also revegetated with local provenance native trees, shrubs, grasses and groundcovers including Westringia fruticosa (Coastal Rosemary), Acacia suaveolens (Sweet-scented Wattle), Lomandra longifolia (Spiny Mat Rush), Correa alba (White Correa), and Dianella caerulea (Blue Flax Lily).

Various exotic and native tree species have been planted adjacent to surrounding buildings on the site, including specimens of Araucaria heterophylla (Norfolk Island Pine), Banksia integrifolia (Coastal Banksia), Melaleuca armillaris (Bracelet Honeymyrtle), Lagunaria patersonii (Norfolk Island Hibiscus) and Metrosideros excelsa (New Zealand Christmas Tree). Densely planted native
