Aerva Javanica
''Aerva javanica'', the kapok bush or desert cotton, is a species of plant in the family Amaranthaceae. It has a native distribution incorporating much of Africa (including Madagascar), and the south-west and south of Asia, and it has become adventitious in northern Australia. Description The plant is herbaceous, multi-stemmed and soft-wooded and bears broad leaves; it often has an erect habit and grows to a height of about . In Western Australia it tends to grow in sandy soils especially along drainage lines. It flowers between January and October. Diplospory, a type of Agamospermy, occurs during the development of female gametophyte in the ovule and hence reduction division does not take place in the Megaspore mother cell. The diploid egg is unfertilized and forms the embryo. Hence daughter plants are exactly clones of the mother. The species uses carbon fixation. It is dioecious, meaning male and female flowers are produced on separate individuals. Uses This herb is de ...

Burm
A berm is a level space, shelf, or raised barrier (usually made of compacted soil) separating areas in a vertical way, especially partway up a long slope.

Etymology The word is one of Middle Dutch and came into usage in English via French. Military use History In medieval military engineering, a berm (or berme) was a level space between a parapet or defensive wall and an adjacent steep-walled ditch A ditch is a small to moderate divot created to channel water. A ditch can be used for drainage, to drain water from low-lying areas, alongside roadways or fields, or to channel water from a more distant source for plant irrigation. Ditches ar ... or moat. It was intended to reduce soil pressure on the walls of the excavated part to prevent its collapse. It also meant that debris dislodged from fortifications would not ...

Desert Reclamation
Desert greening is the process of man-made reclamation of deserts for ecological reasons (biodiversity), farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life. The term "desert greening" is intended to apply to both cold and hot arid and semi-arid deserts (see Köppen climate classification system). It does not apply to ice capped or permafrost regions. Desert greening has the potential to help solve global water, energy, and food crises. It pertains to roughly 32 million square kilometres of land. Methods *Managed intensive rotational grazing *Holistic management * Landscaping methods to reduce evaporation, erosion, consolidation of topsoil, sandstorms, temperature and more *Permaculture in general – harvesting runoff rainwater to grow plant communities polyculture, composting or multitrophic agriculture *Planting trees (pioneer species) and salt-loving plants (halophytes), such as Salicornia *Regeneration of sa ...

Herbs
In general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. ''Herbs'' generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while ''spices'' are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits. Herbs have a variety of uses including culinary, medicinal, aromatic and in some cases, spiritual. General usage of the term "herb" differs between culinary herbs and medicinal herbs; in medicinal or spiritual use, any parts of the plant might be considered as "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin and pericarp. The word "herb" is pronounced in Commonwealth English, but is common am ...

Flora Of The Arabian Peninsula
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ...

Ngarluma
The Ngarluma are an Indigenous Australian people of the western Pilbara area of northwest Australia. They are coastal dwellers of the area around Roebourne and Karratha. Not including Millstream. Language The Ngarluma language belongs to the Ngayarda branch of the Pama-Nyungan family. It is a highly inflected suffixing language, with, unusually, a Nominative-Accusative case-marking system, with verbs inflected for Tense, Aspect and Mood. The Ngarluma on contact with whites and distant tribes appeared to have reserved their grammatically complex language for conversations among themselves while adopting a simplified version when interacting with strangers. There are an estimated 20 full speakers, most are older generation. History It would appear that the Ngarluma adapted quickly to the developing pearling industry along the northwest coast, perhaps travelling down to get work at Cossack 300 miles south. This hypothesis is based on the fact that the vocabulary list pr ...

Yindjibarndi
The Yindjibarndi are an Aboriginal Australian people of the Pilbara region of Western Australia. They form the majority of Aboriginal people around Roebourne (the Millstream area). Their traditional lands lie around the Fortescue River. Language Yindjibarndi, with around 1000 speakers has been called the most innovative descendant of then proto-Ngayarta language. It is mutually intelligible with Kurruma. Due to their displacement in the colonisation process which forced them into Roebourne, many speakers are Ngarluma people who have adopted Yindjibarndi. Their spatial concepts regarding landscape of do not translate with any equivalent conceptual extension into English. Ecology Traditionally, until the arrival of Europeans, the Yindjibarndi lived along the middle sector of the valley through which the Fortescue River runs, and the nearby uplands. Beginning in the 1860s pastoralists established cattle stations on their homeland, and the Yindjibarndi were herded into settlement ...

Ceiba Pentandra
''Ceiba pentandra'' is a tropical tree of the order Malvales and the family Malvaceae (previously emplaced in the family Bombacaceae), native to Mexico, Central America and the Caribbean, northern South America, and (as the variety ''C. pentandra'' var ''guineensis'') West Africa. A somewhat smaller variety was introduced to South and Southeast Asia, where it is cultivated. The tree and the cotton-like fluff obtained from its seed pods are commonly known in English as kapok, a Malay-derived name which originally applied to ''Bombax ceiba'', a native of tropical Asia. In Spanish-speaking countries the tree is commonly known as "ceiba" and in French-speaking countries as fromager. The tree is cultivated for its cottonlike seed fibre, particularly in south-east Asia, and is also known as the Java cotton, Java kapok, silk-cotton or samauma. Characteristics The tree grows to as confirmed by climbing and tape drop with reports of Kapoks up to . These very large trees are in the N ...

Arabia
The Arabian Peninsula, (; ar, شِبْهُ الْجَزِيرَةِ الْعَرَبِيَّة, , "Arabian Peninsula" or , , "Island of the Arabs") or Arabia, is a peninsula of Western Asia, situated northeast of Africa on the Arabian Plate. At , the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula includes Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE), and Yemen, as well as the southern portions of Iraq and Jordan. The largest of these is Saudi Arabia. In the classical era, the southern portions of modern-day Syria, Jordan, and the Sinai Peninsula were also considered parts of Arabia (see Arabia Petraea). The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and southwest, the Persian Gulf and the Gulf of Oman to the northeast, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Oce ...
