Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae (''Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the large-scal ...

Myrtaceae
Myrtaceae (), the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid ...

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Private Property
Private property is a legal designation for the ownership of property by non-governmental Capacity (law), legal entities. Private property is distinguishable from public property, which is owned by a state entity, and from Collective ownership, collective or cooperative property, which is owned by one or more non-governmental entities. Private property is foundational to capitalism, an economic system based on the private ownership of the means of production and their operation for Profit (economics), profit. As a legal concept, private property is defined and enforced by a country's political system. History The first evidence of private property may date back to the Babylonians in 1800 BC, as evidenced by the archeological discovery of Plimpton 322, a clay tablet used for calculating property boundaries; however, written discussions of private property were not seen until the Persian Empire, and emerged in the Western tradition at least as far back as Plato.

State Ownership
State ownership, also called public ownership or government ownership, is the ownership of an Industry (economics), industry, asset, property, or Business, enterprise by the national government of a country or State (polity), state, or a public body representing a community, as opposed to an individual or Private property, private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from Public good, public goods and government services financed out of a Government budget, government's general budget. Public ownership can take place at the Central government, national, regional government, regional, local government, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, Collective ownership, collective/cooperative, and common ownership. In marke ...

Primary Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without Disturbance (ecology), disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and Canopy (biology), canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debr ...

Forest Cover
Forest cover is the amount of trees that covers a particular area of land. It may be measured as relative (in percent) or absolute (in square kilometres/ square miles). Nearly a third of the world's land surface is covered with forest, with closed-canopy forest accounting for 4 - 5 billion hectares of land. Forests provide many ecosystem services that humans and animals cannot survive without, but anthropogenic actions and climate change are threatening global forest cover in potentially irreversible ways. Global patterns Forest cover by the numbers According to the FAO's Global Forest Resources Assessment 2020, the world has a total forest area of 4.06 billion hectares (10.0 billion acres), which is 31% of the total land area. More than one-third of the world's forest cover is primary forest: naturally regenerated forests with native species and no visible indication of human activity. More than half (54%) of the world's forests are found in only five countries (Brazil, C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-stick Farming
Fire-stick farming, also known as cultural burning and cool burning, is the practice of Aboriginal Australians regularly using fire to burn vegetation, which has been practised for thousands of years. There are a number of purposes for doing this special type of controlled burning, including to facilitate hunting, to change the composition of plant and animal species in an area, weed control, hazard reduction, and increase of biodiversity. While it had been discontinued in many parts of Australia, it has been reintroduced in the 21st century by the teachings of custodians from areas where the practice is extant in continuous unbroken tradition such as the Noongar peoples' cold fire. Terminology The term "fire-stick farming" was coined by Australian archaeologist Rhys Jones in 1969. It has more recently been called cultural burning and cool burning. History Aboriginal burning has been proposed as the cause of a variety of environmental changes, including the extinction of t ...

History Of Australia (1788-1850)
The history of Australia is the history of the land and peoples which comprise the Commonwealth of Australia. The modern nation came into existence on 1 January 1901 as a federation of former British colonies. The human history of Australia, however, commences with the arrival of the first ancestors of Aboriginal Australians from Maritime Southeast Asia between 50,000 and 65,000 years ago, and continues to the present day multicultural democracy. Aboriginal Australians settled throughout continental Australia and many nearby islands. The Aboriginal art, artistic, Aboriginal music, musical and Dreamtime, spiritual traditions they established are among the longest surviving in human history. The ancestors of today's ethnically and culturally distinct Torres Strait Islanders arrived from what is now Papua New Guinea around 2,500 years ago, and settled the islands on the northern tip of the Australian landmass. Dutch navigators explored the western and southern coasts in the 17t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
