Kathleen Island
Kathleen Island is a steeply cliffed island that lies within Port Davey, an oceanic inlet, located in the south west region of Tasmania, Australia. The island has an area of approximately and is contained with the Southwest National Park, part of the Tasmanian Wilderness World Heritage Site and the Port Davey/Bathurst Harbour Marine Nature Reserve. Features and location Part of the Breaksea Islands Group, Kathleen Island has an elevation of approximately above sea level. The island is almost split by a deep gulch.Brothers, Nigel; Pemberton, David; Pryor, Helen; & Halley, Vanessa. (2001). ''Tasmania’s Offshore Islands: seabirds and other natural features''. Tasmanian Museum and Art Gallery: Hobart. Kathleen island is part of the Port Davey Islands Important Bird Area, so identified by BirdLife International because of its importance for breeding seabirds. Most of the island is covered by thick scrub and rainforest. Recorded breeding seabird species are the little p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South West Tasmania
South West Tasmania is a region in Tasmania that has evoked curiosity and wonder during the period of European presence on the island. Initially relatively unexplored by Europeans, in the mid-twentieth century the area was considered for its potential resources for development. Much of the area is now protected within the Southwest National Park and as part of the Tasmanian Wilderness World Heritage Area. The most notable controversy occurring in the region was the flooding of Lake Pedder as part of a hydro-electric development, in 1972. This was followed, further north, by the proposed damming of the Franklin River in the early 1980s, which did not proceed. Southwest is a locality that covers most of the region. The locality (and therefore the region) is in the local government areas of Derwent Valley (29%), Huon Valley (20%), Central Highlands (7%) and West Coast (44%). Its central point, near the encircled locality of Strathgordon, is about west of the town of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Height Datum
The Australian Height Datum was introduced in 1971 as the official vertical datum for Australia, and thereby serves as the Benchmark (surveying), benchmark to which all height measurements are referred. The Australian Height Datum is an amalgamation of decades of spirit levelling work conducted by numerous state and territory authorities across the country, and was corrected to align with the Mean sea-level, mean sea level observations of thirty tide gauges positioned around the entire coastline. While it remains the published vertical datum for all surveying and engineering operations performed throughout Australia, newer technologies have uncovered numerous deficiencies, offsets and distortions within the Australian Height Datum, leading to discussions about defining a new Australian vertical datum. Background The National Mapping Council (pre-1945) Prior to the creation of the Australian Height Datum, Levelling, levelling surveys were carried out by professional surveyor ...

List Of Islands Of Tasmania
Tasmania is the smallest and southernmost state of Australia. The Tasmanian mainland itself is an island, with an area of - 94.1% of the total land area of the state. There are more than 1000 smaller islands which have a combined area of , making up the remaining 5.9% of total land area. Classification structure A considerable number of Tasmanian islands are identified as being in island groups, including the Breaksea, Furneaux, Hogan, Hunter, Kent, Maatsuyker, Mutton Bird, New Year, Swainson, Trumpeter, and Waterhouse groups. Regions Similar to Regions of Tasmania the islands are generally distinguished by the coast that they are adjacent to, as well as Bass Strait - the main separation from the mainland state of Victoria. Five regions are aligned to the north coast and Bass Strait - ''North West Islands'' (including King Island), ''North Coast Islands'', ''North Bass Strait Islands'', ''Furneaux Islands'', and ''North East Islands''. The southern groups are ''South ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallic Skink
:''"Metallic skink" may also refer to the garden skink (Lampropholis delicata)''. ''Carinascincus metallicus'', the metallic cool-skink or metallic skink is a species of skink in the family Scincidae. It is endemic to Australia, found in southern Victoria, Australia, Victoria, as well as in Tasmania where it is the most widespread and common lizard, occurring on many offshore islands in Bass Strait as well as the mainland. It gives birth to live young. It is highly variable in colour and pattern, and may be a complex of closely related species.Cogger, H.G. (1979). ''Reptiles and Amphibians of Australia''. Reed: Sydney. Description and Identification The Metallic Skink exhibits a range of colour variations depending on its habitat. It is typically brown with pale or dark streaks, sometimes forming distinct longitudinal stripes along its body. The dorsal scales have a metallic sheen, which gives the species its name. The underside is usually grey or white with dark spots on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-tailed Shearwater
The short-tailed shearwater or slender-billed shearwater (''Ardenna tenuirostris''; formerly ''Puffinus tenuirostris''), also called yolla or moonbird, and commonly known as the muttonbird in Australia, is the most abundant seabird species in Australian waters, and is one of the few Australian native birds in which the chicks are muttonbirding, commercially harvested. It is a migratory species that breeds mainly on small islands in Bass Strait and Tasmania and migrates to the Northern Hemisphere for the boreal summer. Taxonomy This shearwater appears to be related to the sooty shearwater, sooty and great shearwaters, which are also blunt-tailed, black-billed species, but its precise relationships are obscure (Austin, 1996; Austin ''et al.'', 2004). These are among the larger species of shearwater, which have been moved to a separate genus, ''Ardenna'' based on a phylogenetic analysis of mitochondrial DNA (Penhallurick & Wink, 2004). Ecology Each parent feeds the single chick fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Penguin
The little penguin (''Eudyptula minor'') is the smallest species of penguin. It originates from New Zealand. It is commonly known as the fairy penguin, little blue penguin, or blue penguin, owing to its slate-blue plumage and is also known by its Māori language, Māori name . It is a Neritic zone, marine neritic species that dives for food throughout the day and returns to burrows on the shore at dusk, making it the only Nocturnality, nocturnal penguin species on land. The Eudyptula novaehollandiae, Australian little penguin (''Eudyptula novaehollandiae''), from Australia and the Otago region of New Zealand, is considered a separate species. ''Eudyptula minor'' feathers are dense in Melanosome, melanosomes, which increase water resistance and give them their unique blue colour. Taxonomy The little penguin was first described by German naturalist Johann Reinhold Forster in 1781. Several subspecies are known, but a precise classification of these is still a matter of dispute. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seabird
Seabirds (also known as marine birds) are birds that are adaptation, adapted to life within the marine ecosystem, marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding ecological niche, niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous geological period, period, while modern seabird families emerged in the Paleogene. Seabirds generally live longer, Reproduction, breed later and have fewer young than other birds, but they invest a great deal of time in their young. Most species nest in Bird colony, colonies, varying in size from a few dozen birds to millions. Many species are famous for undertaking long annual bird migration, migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even on each other. Seabirds can be highly pelagic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainforest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere. Definition Rainforests are cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Port Davey Islands Important Bird Area
The Port Davey Islands Important Bird Area comprises over 20 small, rocky islands scattered both within, and in the vicinity of, the mouth of Port Davey, an inlet on the south-west coast of Tasmania, Australia. They all lie within the Southwest National Park and are important for breeding seabirds. Birds The sparsely vegetated islands, with a collective area of 163 ha, have been identified by BirdLife International as an Important Bird Area (IBA) because together they support over 1% of the world populations of short-tailed shearwaters (c. 950,000 breeding pairs), fairy prions (c. 27,000 breeding pairs), little penguins (c. 16,500 breeding pairs) and black-faced cormorants (up to 230 breeding pairs). Pacific gulls and sooty oystercatchers also nest in the islands.BirdLife International. (2011). Important Bird Areas factsheet: Port Davey Islands.

Tasmania Parks And Wildlife Service
Tasmania Parks and Wildlife Service is the government body responsible for managing protected areas of Tasmania on public land, such as national parks, historic sites and regional reserves. Historically it has also had responsibility for managing wildlife, including game. History The National Parks and Wildlife Service was set up on 1 November 1971 after controversy surrounding the proposal to flood Lake Pedder and the unsuccessful attempts to prevent the project going ahead. A Select Committee formed from the interested parties recommended the establishment of a professional park service to properly manage the natural environment in Tasmania, and to replace the former Scenery Preservation and Animals & Birds Protection Boards, previously responsible for scenic reserves (including national parks) and wildlife sanctuaries respectively. The new service initially had a staff of 59 under inaugural Director Peter Murrell. The '' National Parks and Wildlife Act 1970'' had made new ...
