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 pengui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South West Tasmania
South West Tasmania is a region in Tasmania that has evoked curiosity as to its resources over the duration of European presence on the island. The more recent is the consideration as a potential area of resources for development and its consideration as World Heritage wilderness. The most notable controversies occurring in the region in the late twentieth century was the flooding of Lake Pedder and the proposed damming of the Franklin River by the Franklin Dam. 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 New Norfolk, the administrative centre for the Derwent Valley Council. The 2016 census has a population of 15 for the state suburb of Southwest. Early surveys Most early walks through the region were for disc ...

Australian Height Datum
The Australian Height Datum was introduced in 1971 as the official vertical datum for Australia, and thereby serves as the 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 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 surveys were carried out by professional surveyors for construction and mapping purposes using only ...

Islands Of South West Tasmania
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The other islands have a combined area of , for a cumulative total of 99.75% of the state. About 1000 smaller islands make up the remaining 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' ...

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, as well as in Tasmania where it is the most widespread and common lizard, occurring on many offshore islands in 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 waterwa ... as well as the mainland. It gives birth to live young.

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 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 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 for 2–3 days and then leaves for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Penguin
The little penguin (''Eudyptula minor'') is a species of penguin from New Zealand. They are commonly known as little blue penguins or blue penguins owing to their slate-blue plumage and are also known by their Māori name . The Australian little penguin (''Eudyptula novaehollandiae'') from Australia and the Otago region of New Zealand is considered a separate species by a 2016 study and a 2019 study. 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. The holotypes of the subspecies ''E. m. variabilis'' and ''Eudyptula minor chathamensis'' are in the collection of the Museum of New Zealand Te Papa Tongarewa. The white-flippered penguin (''E. m. albosignata'' or ''E. m. minor morpha albosignata'') is currently considered by most taxonomists to be a colour morph or subspecies of ''Eudyptula minor.'' In 2008, Shirihai treated th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being 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 " 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, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

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).

It prefers rocky coastlines, but will occasionally live in estuari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tasmania Parks And Wildlife Service
Tasmania Parks and Wildlife Service is the government body responsible for 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. The service initially had a staff of 59. The '' National Parks and Wildlife Act 1970'' had made provisions for the conservation of fauna and flora and the establishment and management of national parks. Mount William, Maria Island and Narawntapu National Parks were set up and Macquarie Island designated as a nature reserve. The creation of an Ar ...
