Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna.
The Swan Coastal Plain in Western Australia is the geographic feature which contains the Swan River as it travels west to the Indian Ocean. The coastal plain continues well beyond the boundaries of the Swan River and its tributaries, as a geological and biological zone, one of Western Australia's Interim Biogeographic Regionalisation for Australia (IBRA) regions. It is also one of the distinct physiographic provinces of the larger West Australian Shield division.
Eucalyptus gomphocephala, known as tuart, is a species of tree, one of the six forest giants of Southwest Australia. Tuart forest was common on the Swan coastal plain, until the valuable trees were felled for export and displaced by the urban development around Perth, Western Australia. The wood is dense, hard, water resistant and resists splintering, and found many uses when it was available. Remnants of tuart forest occur in state reserves and parks, the tree has occasionally been introduced to other regions of Australia and overseas. Remaining trees are vulnerable to phytophthora dieback, an often fatal disorder, including a previously unknown species discovered during analysis of dead specimens.
Western Australia occupies nearly one third of the Australian continent. Due to the size and the isolation of the state, considerable emphasis has been made of these features; it is the second largest administrative territory in the world, after Yakutia in Russia, despite the fact that Australia is only the sixth largest country in the world by area, and no other regional administrative jurisdiction in the world occupies such a high percentage of a continental land mass. It is also the only first level administrative subdivision to occupy the entire continental coastline in one cardinal direction.
Grevillea drummondii, commonly known as Drummond's grevillea, is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a low, spreading to erect shrub with narrowly elliptic to narrowly egg-shaped leaves with the narrower end towards the base, and dense groups of cream-coloured flowers that turn pink or red as they age.
The Drummond Nature Reserve is an A class nature reserve 10 kilometres west of Bolgart, Western Australia. Named after the botanist James Drummond, the reserve has 439 species of vascular plants within its boundaries, including two rare and seven priority species.
Xanthorrhoea preissii, known as balga, is a widespread species of perennial monocot in Southwest Australia.
Grevillea quercifolia, commonly known as the oak-leaf grevillea, is a species of flowering plant in the protea family and is endemic to the southwest of Western Australia. It is a straggly to sprawling shrub usually with pinnatifid or serrated leaves, and oval to cylindrical clusters of pale to deep pink flowers.
Grevillea evanescens is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect to spreading shrub with oblong to elliptic leaves and clusters of pale to bright red and cream-coloured flowers.
Petrophile shuttleworthiana is a flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a prickly shrub with creamy-white flowers growing within a radius of about 400 km (200 mi) of Perth.
Grevillea florida is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a erect, low shrub with linear to narrowly elliptic leaves, and clusters of hairy, white to creamy yellow flowers with a yellow- or orange-tipped style that ages to red.
Grevillea manglesioides is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a spreading shrub usually with wedge-shaped leaves with lobed ends, and toothbrush-shaped clusters of flowers, the colour varying with subspecies.
Corymbia calophylla – Xanthorrhoea preissii woodlands and shrublands of the Swan Coastal Plain is an ecological community in the Southwest Australia ecoregion.
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.
Grevillea elongata is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a shrub with divided leaves with sharply-pointed linear lobes, and conical or cylindrical groups of white flowers.
The Shale Sandstone Transition Forest, also known as Cumberland Shale-Sandstone Ironbark Forest, is a transitory ecotone between the grassy woodlands of the Cumberland Plain Woodlands and the dry sclerophyll forests of the sandstone plateaus on the edges of the Cumberland Plain in Sydney, Australia. Listed in 2001 under the Environment Protection and Biodiversity Conservation Act 1999, the forest lies between other ecological communities found on shale or sandstone substrates.
The Banksia Woodlands of the Swan Coastal Plain is a protected sclerophyll community situated in the Swan Coastal Plain, Western Australia that predominantly consists of bankias. Listed as endangered under the Environment Protection and Biodiversity Conservation Act 1999, it was once a near-incessant band of large shrub patches around Perth and other nearby coastal areas.
