Beatrice Islets
Beatrice Islets are pair of islets in the Australian state of South Australia located in Nepean Bay on the north coast of Kangaroo Island about east of Kingscote. The islets and adjoining intertidal areas are notable as habitat for bird life. The islet pair has enjoyed protected area status since 1909 and since at least 1972, have been part of the Beatrice Islet Conservation Park. During either the 1960s or the 1970s, the islets were extensively damaged by an exercise to remove an infestation of South African boxthorn. Description Beatrice Islets are pair of islets located in Nepean Bay about east of Kingscote on Kangaroo Island in South Australia.DMH, 1985, Charts 11 & 12BIA, 2005, page 185 The Beatrice Islets along with Busby Islet are three high points on the southern edge of a spit that is exposed at low water.

Nepean Bay
Nepean Bay is a bay located on the north-east coast of Kangaroo Island in the Australian state of South Australia about south-south-west of Adelaide.

A Directory Of Important Wetlands In Australia
A Directory of Important Wetlands in Australia (DIWA) is a list of wetlands of national importance to Australia published by the Department of Climate Change, Energy, the Environment and Water. Intended to augment the list of wetlands of international importance under the Ramsar Convention, it was formerly published in report form, but is now essentially an online publication. Wetlands that appear in the ''Directory'' are commonly referred to as "DIWA wetlands" or "Directory wetlands". Criteria for determining wetland importance Using criteria agreed in 1994, a wetland can be considered “nationally important” if it satisfies at least one of the following criteria: # It is a good example of a wetland type occurring within a biogeographic region in Australia. # It is a wetland which plays an important ecological or hydrological role in the natural functioning of a major wetland system/complex. # It is a wetland which is important as the habitat for animal taxa at a vulnerable st ...

National Parks And Wildlife Act 1972
Protected areas of South Australia, consisting of protected areas located within South Australia and its immediate onshore waters and which are managed by South Australian Government agencies. As of 2018, South Australia contained 359 separate protected areas declared under the ''National Parks and Wildlife Act 1972'', the ''Crown Land Management Act 2009'' and the ''Wilderness Protection Act 1992''. Together, they cover a total land area of or 21.5% of the state's area. Jurisdiction The jurisdiction for legislation of protected areas within South Australia and the immediate onshore waters known officially as "the coastal waters and waters within the limits of South Australia" is that of the South Australian government. The ''National Parks and Wildlife Act 1972'' authorises the creation and management of protected areas, which form the majority of South Australia’s contribution to the National Reserve System. Other South Australian legislation that may create protected ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Governance in the colony was organised according to the principles developed by Edward Gibbon Wakefield, Edward Wakefield, where settlement would be conducted by free settlers rather than convicts.

Guano
Guano (Spanish from ) is the accumulated excrement of seabirds or bats. Guano is a highly effective fertiliser due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern Intensive farming, input-intensive farming. The demand for guano spurred the human colonisation of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and the loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, Fungus, fungi, invertebrates, and vertebrates. The loss of bats from a cave can result in the extinction of species that rely on their guano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spit (landform)
A spit (cognate with the word for a rotisserie bar) or sandspit is a deposition (geology), deposition shoal, bar or beach landform off coasts or lake shores. It develops in places where re-entrance occurs, such as at a cove's headlands, by the process of longshore drift by longshore currents. The drift occurs due to waves meeting the beach at an oblique angle, moving sediment down the beach in a zigzag pattern. This is complemented by longshore currents, which further sediment transport, transport sediment through the water alongside the beach. These currents are caused by the same waves that cause the drift. Hydrology and geology Where the direction of the shore inland ''re-enters'', or changes direction, for example at a headland, the longshore current spreads out or dissipates. No longer able to carry the full load, much of the sediment is dropped. This is called deposition. This submerged bar of sediment allows longshore drift or littoral drift to continue to transport sed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islet
An islet ( ) is generally a small island. Definitions vary, and are not precise, but some suggest that an islet is a very small, often unnamed, island with little or no vegetation to support human habitation. It may be made of rock, sand and/or hard coral; may be permanent or tidal (i.e. surfaced reef or seamount); and may exist in the sea, lakes, rivers or any other sizeable bodies of water. Definition As suggested by its origin ''islette'', an Old French diminutive of "isle", use of the term implies small size, but little attention is given to drawing an upper limit on its applicability. The World Landforms website says, "An islet landform is generally considered to be a rock or small island that has little vegetation and cannot sustain human habitation", and further that size may vary from a few square feet to several square miles, with no specific rule pertaining to size. Other terms * Ait (/eɪt/, like eight) or eyot (/aɪ(ə)t, eɪt/), a small island. It is espe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Lycium ferocissimum'', the African boxthorn or boxthorn, is a shrub in the nightshade family (Solanaceae) indigenous to South Africa. Distribution The species is native to the Western Cape and Eastern Cape provinces in South Africa, where it tends to occur in sands along the southern coast. It has also been recorded in the Free State, but these may represent introductions. It has been widely introduced in South Africa and elsewhere in Africa, as far north as Morocco.Venter, A.M. (2000). Taxonomy of the Genus ''Lycium'' L. (Solanaceae) in Africa. Thesis (Ph.D. (Botany and Genetics))--University of the Free State. https://scholar.ufs.ac.za/handle/11660/1960?show=full It has been recorded in Sardinia, Italy. This shrub is found in other Mediterranean countries such as Tunisia and Spain. There is one record in France from 2020. It has become naturalised in Australia and New Zealand.
