Ecology of Sydney
_Airport_site_-_Anton_Rd.JPG)
The ecology of Sydney, located in the state of New South Wales, Australia, is diverse for its size,[2] featuring biomes such as wet and dry sclerophyll forests or woodlands, shrublands, subtropical and evergreen temperate rainforests, heathlands, wetlands and grasslands,[3][4] with the combination of climate, topography, moisture, and soil influencing the dispersion of these ecological communities across a height gradient from 0 to 200 metres (0 to 700 ft).[5] There are many hiking trails, paved and unpaved roads for exploring the many different biomes and ecosystems.[6][7][8]
Dry sclerophyll forests, the most predominant biome in the region, mainly occur in the Cumberland Plain west of Sydney CBD and would contain eucalyptus trees that are usually in open woodlands with dry shrubs and sparse grass in the understory, reminiscent of Mediterranean forests.[9] On the other hand, wet sclerophyll forests, which are Temperate broadleaf and mixed forests, part of Eastern Australian temperate forests, have narrow, relatively tall, dense trees with a lush, moist understorey of fleecy shrubs and tree ferns, which are found in the cooler or wetter areas such as Northern Suburbs, Forest District, North Shore and in the Blue Mountains.[10]
The Sydney Turpentine-Ironbark Forest, one of six main indigenous forest communities of Sydney, is an example of a dry sclerophyll forest, containing trees around 20–30 metres tall, with ground cover composed of flowering shrubs and native grasses.[11] The Blue Gum High Forest, strictly found in northern parts of Sydney, is a wet sclerophyll forest example, where the annual rainfall is over 1100 mm (43 in), with its trees between 20 and 40 metres tall.[12]
The first European settlers saw Sydney's vegetation as "extremely barren, poor, hungry sand, thickly studded with rocks, growing nothing but a few miserable stunted gums and dwarf underwood".[13] It has been calculated that around 98,000 hectares of native vegetation remains in the Sydney metropolitan area, shaping the geography of Sydney, about half of what is likely to have been existing at the time of European arrival.[14]

- Cumberland Plain Woodland – These are shrub and grass eucalyptus communities located in areas of low to moderate rainfall (less than 950 millimetres annually) and are most commonly found in large parts of the Sydney metropolitan area, namely in Western Sydney or the Cumberland Plain. Moist Shale Woodlands[27] also exist within this biome, but they're distinguished by their lusher plant habitats.[28] It is a dry woodland remnant containing waxy-leaved shrubs, twiners, herbs and small trees in a grassy understorey.[29] It has a number of sub-regions: Moist Shale Woodlands, Western Sydney dry rainforest, Shale gravel transition forest, and Shale gravel transition forest, among others.[30]
- Dry sclerophyll forests
- Sydney Coastal Dry Sclerophyll Forests – Predominant on the northeast parts of the Woronora Plateau on ridgelines within the Royal, Heathcote and Dharawal national parks and Garawarra State Conservation Area in southern Sydney. It is also present in north of Sydney Harbour and extends to both sides of the Hawkesbury River at Pittwater, Hornsby LGA and Pennant Hills.[31][32]
- Sydney Hinterland Dry Sclerophyll Forests – Found in the drier parts (less than 950 mm) of the Woronora Plateau, also in Appin, Sandy Point, pockets in the southwestern edges of the Cumberland Plain (on the doorsteps of the Blue Mountains), and on the foreshores of the Hawkesbury River, it features 10–25 m tall eucalyptus trees with ostensible sclerophyll shrub understorey and open groundcover of sclerophyll sedges.[33][34]
- Cooks River/Castlereagh ironbark forest – Found in Castlereagh and Holsworthy, and a few remnants in the cities of Auburn, Bankstown and Liverpool, it is an ironbark shrub-grass forest located in western Sydney that sit on gravelly-clay soils and is made up of a moderately tall open eucalyptus forest or woodland to a low compact brush of paperbarks with nascent eucalypts. Broad-leaved ironbark (Eucalyptus fibrosa) is the most commonly spotted tree.[35][36]
- Sydney Sand Flats Dry Sclerophyll Forests – Present in northern Holsworthy with smaller examples at Rookwood and Villawood and is dominated by Eucalyptus sclerophylla.[37]

- Forested wetlands
- Sydney coastal river-flat forest – Found on the river flats of the coastal floodplains in most parts of the plain that has rivers or creeks. It has an open tree layer of eucalypts which may surpass 40 m in height.[29]
- Coastal Swamp Forests – Occupies the low-lying coastal river flats, swamps and sand depressions, which are mostly cleared from the Sydney metropolitan area, but still exist in places like Georges River National Park, Milperra, Chipping Norton, Prospect Creek and Kurnell in southeastern Sydney, and Wheeler Heights, Narrabeen and Dee Why in the Northern Beaches.[45]
- Coastal Floodplain Wetlands – They cover a series of eucalypt and casuarina dominated communities found on low-lying coastal alluvial soils, such as in Georges River and its tributaries in northern Woronora and the lowlands of Blue Mountains. They are dominated by Microlaena stipoides.[46]

Wildlife
Common native species
Commonly sighted in Sydney, Australian magpies are known for their distinctive, "gargling" calls.
Noisy miners are ubiquitous in urban, suburban and woodland areas.
Australian ravens are notable for their screechy, high pitched ah-ah-aaaah calls.
The pied currawong is a common bird in the plain and is usually seen in urban forests and backyards.
Grey-headed flying-foxes are found in suburban woods.
Blue-tongues are the predominant skink species in Sydney.
Redback spiders, which are venomous, became widespread in the urban areas by the early 20th century.
Grey butcherbirds, known for their frisky song, are found in woodlands, acacia shrublands and residential townships.
Crested pigeons are usually found in the open grasslands and wooded areas of the plain.
The spotted dove is a small, long-tailed pigeon that was introduced in Australia in the 1860s.
The snake-eyed skink is often seen on vertical surfaces such trees, fences and walls.
Sydney huntsman spiders are found in tree logs, barks and rock walls.
The fauna of the Sydney area is diverse and its urban area is home to variety of bird and insect species, and also a few bat, arachnid and amphibian species. Introduced birds such as the house sparrow, common myna and feral pigeon are ubiquitous in the CBD areas of Sydney.[54][55] Moreover, possums, bandicoots, rabbits, feral cats, lizards, snakes and frogs may also be present in the urban environment, albeit seldom in city centers.[56]
About 40 species of reptiles are found in the Sydney region and 30 bird species exist in the urban areas.[57][58][59] Sydney's outer suburbs, namely those adjacent to large parks, have a great diversity of wildlife.[60] Since European settlement and the subsequent bushland clearing for the increasing population, 60% of the original mammals are now considered endangered or vulnerable, and many reptile species are experiencing population diminution and are becoming elusive.[61]
