Natural Area Survey

In 2010 a Natural Area Survey was carried out by P&J Smith Ecological Consultants to review the native vegetation, flora and fauna of the North Sydney local government area.

A total of about 49ha of bushland has been identified and mapped, representing less than 5% of the total land area of the LGA.

As a result, 12 native vegetation communities have been distinguished in North Sydney and a total of 347 native vascular plant species and subspecies have been recorded.

Here are each of the 12 vegetation communities that were distinguished with all plant species that have been recorded in these communities in 2010.


Allocasuarina Scrub (20KB)

Open-scrub dominated by Allocasuarina Iittoralis (Black She-oak). The distribution is restricted to two sites in Tunks Park, where it occurs on steep slopes on Hawkesbury Sandstone.


Angophora Foreshore Forest (28KB)

Open-forest, occasionally tall open-forest, in which the dominant tree species is Angophora costata (Sydney Red Gum). This vegetation community is found both along the harbour foreshores and up to 1km away.


Blackbutt Gully Forest (26KB)

Open-forest or tall open-forest, in which the dominant tree species is Eucalyptus pilularis (Blackbutt). It occurs in Wollstonecraft, Cremorne and Cammeray. 


Disclimax Sandstone Scrub (24KB)

Is open to closed scrub, or a forest of mixed and variable composition. A 'disclimax' community is an altered community that has replaced the original vegetation community as a result of disturbance. Disclimax Sandstone Scrub develops in sites where the original eucalypt forest vegetation has been subject to clearing or dieback.


Estuarine Mangrove Forest (14KB)

Is a low closed-forest of Avicennia marina (Grey Mangrove) growing on intertidal mudflats. In North Sydney its distribution is restricted to Core Cove Reserve where it grows on the intertidal mudflats at the mouth of Berry Creek. 


Estuarine Saltmarsh (14KB)

Herbland of Sarvovorinia quinqueflora (Samphire) and Suaeda australis (Seablite), growing on intertidal mudflats. The introduced species, Atriplex prostrata (Orache), is a co-dominant. The distribution of this vegetation community is restricted to Gore Cove Reserve and it is listed as an endangered ecological community in NSW. 


Sandstone Gallery Rainforest (21KB)

Closed-forest dominated by Acmena smithii (Lilly Pilly), Ceratopetalum apetalum (Coachwood) and Pittosporum undulatum (Pittosporum), in various combinations. This vegetation community occurs on steep, sheltered slopes besides rock creeklines on Hawkesbury Sandstone in Wollstonecraft and Cremorne.


Kunzea Scrub (20KB)

Open-scrub dominated by Kunzea ambigua (Tick Bush), growing on top of harbour headlands with extensive flat sandstone outcrops. It occurs in Wollstonecraft and Waverton.


Mixed Sandstone Gully Forest (22KB)

Open-forest of mixed tree composition. Distribution is restricted to Wonga Road Reserve and Tobruk Avenue Lookout, occuring on a steep slope beside Willoughby Bay.


Forest Red Gum Foreshore Forest (18KB)

Open-forest in which the dominant tree species is Eucalyptus tereticornis (Forest Red Gum). This vegetation community is a rare and unusual type of Turpentine-Ironbark Forest. It is listed as endangerd under NSW and Commonwealth legislation. In North Sydney it only occurs on one site at Badangi Reserve on the sides and across the top of a small peninsula in Balls Head Bay.


Estuarine Swamp Oak Forest (18KB)

Open-forest dominated by Casuarina glauca (Swamp Oak), growing adjacent to the intertidal zone. This vegetation community is listed as an endangered ecological community in NSW and occurs in Wollstonecraft and Cammeray.


Sandstone Foreshore Scrub (22KB)

Open-scrub or closed-scrub growing on steep sandstone slopes adjacent to the harbour, with extensive sandstone outcrops and cliffs. It is similar to Disclimax Sandstone Scrub, but appears to be a natural community. This vegetation community occurs in Wollstonecraft, Waverton and Cremorne Point.
