Lake Joondalup
Lake Joondalup is a medium-sized freshwater lake in Perth, Western Australia. It is in the Perth northern suburbs of Joondalup, Wanneroo, and Edgewater. It is a nature reserve and part of the Yellagonga Regional Park. Description Lake Joondalup is Perth's largest metropolitan freshwater lake located in the Yellagonga Regional Park. It has several islands, and a large sandbank during the dry summer months. The largest island is colloquially named "Snake Island" by locals for good reason as the wetland habitat supports a healthy population of various snakes, including the dugite and tiger snake. The lake and bush reserve is a dynamic habitat supporting much wildlife including turtles, ducks and many other birds. Most of the banks are either swampland or reeds. Significant natural attractions include Neil Hawkins Park, Joondalup and Picnic Cove, and Edgewater. Neil Hawkins Park was named after a chairman of the former Metropolitan Region Planning Authority, and is a popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joondalup
Joondalup () is a suburb of Perth, Western Australia, approximately north of Perth's central business district. It contains the central business district of the regional City of Joondalup and acts as the primary urban centre of Perth's outer northern suburbs. History During the latter part of the 1960s, the '' Metropolitan Regional Planning Authority'' developed the '' Corridor Plan for Perth'' which was published and adopted in 1970. The plan called for the creation of five "sub-regional" retail centres (Fremantle, Joondalup, Midland, Armadale and Rockingham) which would form the commercial and economic focus of each "node", and take the retail burden away from the CBD. The Corridor Plan was not endorsed by Parliament until 1973. In order to grow both the five "sub-regional" retail centres and these off-corridor regional shopping centres, a ''Retail Shopping Policy'' was developed by MRPA in 1976, and a ''Perth Metropolitan Region Retail Structure Plan'' was put in place ...

Duck
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Of Perth, Western Australia
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Lakes Of Australia
Natural freshwater lakes in Australia are rare due to the general absence of glacial and tectonic activity in Australia. Types Most lakes in Australia fall within one of five categories. Excluding lakes created by man-made dams for water storage and other purposes, one can identify the following: * coastal lakes and lagoons including perched lakes; * natural freshwater inland lakes, often ephemeral and some part of wetland or swamp areas; * the Main Range containing mainland Australia's five glacial lakes. In Tasmania, due to glaciation, there are a large number of natural freshwater lakes on the central plateau, many of which have been enlarged or modified by hydro-electric developments; * predominantly dry, salt lakes in the flat desert regions of the country lacking organised drainage; and * lakes created in volcanic remnants.

Short-billed Black Cockatoo
Carnaby's black cockatoo (''Zanda latirostris''), also known as the short-billed black cockatoo, is a large black cockatoo endemic to southwest Australia. It was described in 1948 by naturalist Ivan Carnaby. Measuring in length, it has a short crest on the top of its head. Its plumage is mostly greyish black, and it has prominent white cheek patches and a white tail band. The body feathers are edged with white giving a scalloped appearance. Adult males have a dark grey beak and pink eye-rings. Adult females have a bone-coloured beak, grey eye-rings and ear patches that are paler than those of the males. This cockatoo usually lays a clutch of one to two eggs. It generally takes 28 to 29 days for the female to incubate the eggs, and the young fledge ten to eleven weeks after hatching. The young will stay with the family until the next breeding season, and sometimes even longer. The family leaves the nesting site after the young fledge until the following year. Carnaby's blac ...

Northern Swan Coastal Plain Important Bird Area
The Northern Swan Coastal Plain Important Bird Area comprises a 2307 km2 tract of land in south-west Western Australia. Description The Important Bird Area (IBA) stretches from the city of Perth northwards along the coast to the town of Guilderton, extending inland for about 40 km, thereby including much of the Swan Coastal Plain north of the Swan River. It is bounded by the Moore River in the north and the Darling Scarp in the east. It includes all native vegetation remnants greater than one hectare in area on private land, water catchments, state forests and nature reserves, including the Yanchep and Neerabup National Parks. The area has a Mediterranean climate. Birds The site has been identified by BirdLife International as an IBA because it supports 4600–15,000 short-billed black cockatoos during their non-breeding season, with a small number of breeding birds, forming the largest population of non-breeding birds in Australia. The IBA also supports sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterbird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys and sea eagles, hunt aquatic prey but do not stay in water for long and lives predominantly over dry land, and are not considered water birds. The term waterbird is also used in the context of conservation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Quarry
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solutional Cave
A solutional cave, solution cave, or karst cave is a cave usually formed in the soluble rock limestone. It is the most frequently occurring type of cave. It can also form in other rocks, including chalk, dolomite, marble, salt beds, and gypsum. Process Bedrock is dissolved by natural acid in groundwater that seeps through bedding-planes, faults, joints and so on. Over geological epochs these openings expand as the walls are dissolved to become caves or cave systems. The portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded. Limestone caves The largest and most abundant solutional caves are located in limestone. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws, calcite rafts and columns. These secondary mineral deposits in caves are called ''speleothems''. Carbonic acid dissoluti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbecue
Barbecue or barbeque (informally BBQ in the UK, US, and Canada, barbie in Australia and braai in South Africa) is a term used with significant regional and national variations to describe various cooking methods that use live fire and smoke to cook the food. The term is also generally applied to the devices associated with those methods, the broader cuisines that these methods produce, and the meals or gatherings at which this style of food is cooked and served. The cooking methods associated with barbecuing vary significantly but most involve outdoor cooking. The various regional variations of barbecue can be broadly categorized into those methods which use direct and those which use indirect heating. Indirect barbecues are associated with North American cuisine, in which meat is heated by roasting or smoking over wood or charcoal. These methods of barbecue involve cooking using smoke at low temperatures and long cooking times, for several hours. Elsewhere, barbecuing more co ...
