The Castlereagh Scribbly Gum and Agnes Banks Woodlands is an endangered sclerophyll woodland community found in western Sydney, New South Wales, Australia. [1] Vegetation comprises low woodlands with sclerophyllous shrubs and an uneven ground layer of graminoids and forbs.
Originally at 615 hectares, it is a low woodland community measuring at only 98 hectares, where it is mostly found near Agnes Banks on the east side of the Hawkesbury River in the Penrith area. Parts of it are preserved at the Agnes Banks Nature Reserve, near Richmond. It is mostly found on the Cumberland Plain on flat or mildly undulating terrain on valley floors, in the Castlereagh area in the north-west, with minor presence near Holsworthy just outside the Cumberland Plain, Kemps Creek and Longneck Lagoon. Having low nutrient soils, it sits on wind-blown sand over the Tertiary Alluvium deposits from the Hawkesbury-Nepean River system, in areas that receives 700–900 mm annual rainfall. [2]
The community morphs into the smaller, Castlereagh Swamp Woodland, a very proximate community which lies on poorly draining clay soils. [3]
Dominant tree species include the namesake Eucalyptus sclerophylla, in addition to Angophora bakeri, Eucalyptus fibrosa, Eucalyptus parramattensis, Eucalyptus racemosa and Banksia serrata, and understorey shrubs such as, Banksia aemula, Melaleuca decora, Hakea sericea, Monotoca scoparia, Leptospermum trinervium, Banksia oblongifolia, Conospermum taxifolium, Ricinocarpos pinifolius, Dillwynia sericea and Persoonia nutans. [2]
Ground layer includes Themeda triandra, Entolasia stricta, Cyathochaeta diandra, Dianella revoluta, Lepidosperma urophorum, Stylidium graminifolium, Lepyrodia scariosa, Mitrasacme polymorpha, Trachymene incisa and Laxmannia gracilis. [3]
Mammals include Ctenotus taeniolatus, Tiliqua scincoides, Petaurus breviceps, Myotis macropus and Trichosurus vulpecula, with frogs such as Litoria verreauxii, Crinia signifera and Limnodynastes tasmaniensis. Birds include Smicrornis brevirostris, Acanthiza reguloides and Acanthiza nana, Petrochelidon nigricans, Artamus cyanopterus, Colluricincla harmonica, Pachycephala rufiventris and Pachycephala pectoralis, Daphoenositta chrysoptera, Melanodryas cucullata, Pardalotus striatus and Pardalotus punctatus, Lichenostomus fuscus, Tyto alba, Entomyzon cyanotis and the rare Petroica goodenovii.

The Avon Wheatbelt is a bioregion in Western Australia. It has an area of 9,517,104 hectares. It is considered part of the larger Southwest Australia savanna ecoregion.
The Sydney Turpentine-Ironbark Forest (STIF) is dry sclerophyll forest community of Sydney, New South Wales, Australia, that is typically found in the Inner West and Northern region of Sydney. It is also among the three of these plant communities which have been classified as Endangered, under the New South Wales government's Threatened Species Conservation Act 1995, with only around 0.5% of its original pre-settlement range remaining.
The Castlereagh Nature Reserve is a protected nature reserve located in the western suburbs of Sydney in New South Wales, Australia. The 495-hectare (1,220-acre) reserve is situated 60 kilometres (37 mi) west of the central business district, approximately 10 kilometres (6.2 mi) north-east of Penrith and located near the townships of Castlereagh and Londonderry. In 1960, 266 hectares was reclaimed for use as a Child Welfare Training School, and in 1971, 389 hectares was reclaimed for the establishment of a liquid waste disposal facility.
The Southern Sydney sheltered forest is a vegetation community found in Sydney, Australia. An open forest composition grading into woodland or scrub, the community is normally associated with sheltered heads and upper inclines of gullies on transitional zones where sandstone outcropping may be present.
Western Sydney Regional Park is a large urban park and a nature reserve situated in Western Sydney, Australia within the suburbs of Horsley Park and Abbotsbury. A precinct of Western Sydney Parklands, a park system, and situated within the heart of the Cumberland Plain Woodland, the regional park features several picnic areas, recreational facilities, equestrian trails, and walking paths within the Australian bush.
The Cooks River/Castlereagh Ironbark Forest (CRCIF) is a 1,101-hectare (2,721-acre) area of dry sclerophyll open-forest to low woodland which occurs predominantly in the Cumberland subregion of the Sydney basin bioregion, between Castlereagh and Holsworthy, as well as around the headwaters of the Cooks River. The majority of the community is found in the north-west section of the Cumberland Subregion in the Castlereagh area between Penrith and Richmond. Other significant patches occur in the Kemps Creek and Holsworthy areas. Smaller remnants occur in the eastern section of the Cumberland Subregion.
The Cumberland Plain Woodland, or Western Sydney woodland, is a grassy woodland community found predominantly in Western Sydney, New South Wales, Australia, that comprises an open tree canopy, a groundcover with grasses and herbs, usually with layers of shrubs and/or small trees.
The Agnes Banks Natural Area is a heritage-listed natural sand deposit, fauna habitat and native flora site at Rickards Avenue in the western Sydney suburb of Agnes Banks in the City of Penrith local government area of New South Wales, Australia.

It was added to the New South Wales State Heritage Register on 2 April 1999.
The Sydney Sandstone Ridgetop Woodland, also known as Coastal Sandstone Ridgetop Woodland, is a shrubby woodland and mallee community situated in northern parts of Sydney, Australia, where it is found predominantly on ridgetops and slopes of the Hornsby Plateau, Woronora Plateau and the lower Blue Mountains area. It is an area of high biodiversity, existing on poor sandstone soils, with regular wildfires, and moderate rainfall.
The ecology of Sydney, located in the state of New South Wales, Australia, is diverse for its size, where it would mainly feature biomes such as grassy woodlands and some sclerophyll forests, with a few pockets of mallee shrublands, subtropical and temperate rainforests (evergreen), heathlands, and wetlands. The combination of climate, topography, moisture, and soil influence the dispersion of these ecological communities across a height gradient from 0 to 200 metres. There are many hiking trails, paved and unpaved roads for exploring the many different biomes and ecosystems.
The New England Peppermint Grassy Woodland is a grassy-woodland community primarily situated in the New England and Northern Tablelands regions in northern New South Wales, Australia.
