Smithton, Tasmania
Smithton is a town on the far north-west coast of Tasmania, Australia. It lies on the Bass Highway, 85 km north-west of Burnie. At the , Smithton had a population of 3,934. Smithton is the administrative centre of the Circular Head Council. History ''Duck River'' Post Office opened on 1 November 1873 and was renamed ''Smithton'' in 1895. In 1905 Smithton was declared a town and the Mowbray swamp (now part of the locality of Mella) was drained for dairy pasture. It was here that, in 1920, the 45,000 year old skeleton of a Zygomaturus (marsupial hippopotamus) was discovered. In 1905, the Jetty at Smithton was 1200m long. The first regular rail service on the Marrawah Tramway started in 1913. In 1919 The Stanley–Trowutta railway commenced services and by 1921 the Smithton to Irishtown link was opened. By 1922 the railway link from Myalla to Wiltshire Junction was completed, thus joining the railways in the municipality to the State system. Smithton High School was opened ...

Duck Bay
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 oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bass Strait
Bass Strait () is a strait separating the island state of Tasmania from the Australian mainland (more specifically the coast of Victoria, with the exception of the land border across Boundary Islet). The strait provides the most direct waterway between the Great Australian Bight and the Tasman Sea, and is also the only maritime route into the economically prominent Port Phillip Bay. Formed 8,000 years ago by rising sea levels at the end of the last glacial period, the strait was named after English explorer and physician George Bass (1771-1803) by European colonists. Extent The International Hydrographic Organization defines the limits of Bass Strait as follows: :''On the west.'' The eastern limit of the Great Australian Bight eing a line from Cape Otway, Australia, to King Island (Tasmania)">King Island and thence to Cape Grim, the northwest extreme of Tasmania]. :''On the east.'' The western limit of the Tasman Sea between Gabo Island and Eddystone Point eing a line fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Pollution
Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests. The pollution may come from a variety of sources, ranging from point source water pollution (from a single discharge point) to more diffuse, landscape-level causes, also known as non-point source pollution and air pollution. Once in the environment these pollutants can have both direct effects in surrounding ecosystems, i.e. killing local wildlife or contaminating drinking water, and downstream effects such as dead zones caused by agricultural runoff is concentrated in large water bodies. Management practices, or ignorance of them, play a crucial role in the amount and impact of these pollutants. Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices. Bad man ...
