Slide 2

Australia is a continent in the Southern Hemisphere. Australia, one of the highly developed countries in the world, attracts with its mild climate. Australia is the sixth largest country in the world in terms of territory, and it is the only state that occupies an entire continent. The Commonwealth of Australia includes the Australian mainland and several islands, the largest of which is Tasmania. On the mainland, diverse nature coexists with modern, densely populated megacities. Although most of the continent is occupied by semi-deserts and deserts, Australia has a variety of landscapes, from alpine grasslands to tropical jungles. Australia is home to unique species of flora and fauna, some of which are not found elsewhere on the planet. Many plants and animals, including giant marsupials, became extinct with the arrival of the aborigines.

Natural areas of Australia

Australia differs from other continents of the globe in its antiquity and unique flora and fauna. They were formed under conditions of long-term isolation of the continent (since the Cretaceous period). Among plants, endemics account for 75% of species. The most characteristic representatives of the flora of Australia are eucalyptus (more than 600 species), acacia (490 species) and casuarina (25 species). Among the eucalyptus trees there are giants reaching 150 m in height, as well as shrubby forms. Araucarias, proteaceae, southern beeches, tree ferns, palms and a number of other plants indicate the presence in the past of land connections with other continents (South America, Africa, Southeast Asia). Among continents, Australia ranks first in the relative area of ​​deserts and semi-deserts and last in forest area. However, only 2% of Australia's forests are of industrial importance. The central and western regions of Australia within the tropical zone are occupied by deserts and semi-deserts with sparse vegetation of hard grasses and shrubby forms of eucalyptus and acacia (scrape). In deserts, special primitive soils are formed, often colored red. Equatorial, subequatorial and tropical rainforests occur in small areas in the far north of the continent and along the eastern windward slopes of the Great Dividing Range. In these forests, palms, ficuses, laurels, tree ferns intertwined with vines grow mainly on red ferralite soils; Eucalyptus trees predominate in the forests of the eastern part. The subequatorial climate zone corresponds mainly to savannas and woodlands (eucalyptus, acacia and casuarina). Red-brown and red-brown soils form under the canopy of light eucalyptus forests and in savannas. Within the subtropical zone in the southeast and southwest of the continent, special natural complexes are formed. In the humid subtropical forests in the southeast of the continent, eucalyptus forests grow on red soils and yellow soils, and evergreen southern beeches grow in the southern part of this zone. In the south-west of the mainland there is a zone of hard-leaved evergreen forests and shrubs of typical Australian species on brown soils. All natural areas of Australia convenient for farming are occupied by fields and plantations of crops imported from Europe and other parts of the world. Along with cereals, grapevines, cotton, corn, rice, many vegetables and fruit trees are well acclimatized here.

Animal world

Slide 6

The unusual appearance of the kangaroo amazed the first Europeans to set foot on the shores of the continent. The image of a kangaroo was then included in the country's coat of arms.

Slide 7

Koalas live in coastal areas in eastern and southern Australia, from Adelaide to the southern part of Cape York Peninsula, as well as on Kangaroo Island, where they were introduced in the early 20th century. They are also common in regions with enough moisture to support forests suitable for koalas. South Australia's koalas were largely wiped out during the first half of the 20th century, but with the help of individuals from Victoria, the koala population in South Australia has been restored. This animal is not native to Tasmania or Western Australia.

Slide 8

The platypus is a secretive, nocturnal, semi-aquatic animal that inhabits the banks of small rivers and standing ponds in eastern Australia over a wide range from the cold plateaus of Tasmania and the Australian Alps to the tropical rainforests of coastal Queensland. The body length of the platypus is 30-40 cm, the tail is 10-15 cm, and it weighs up to 2 kg. Males are about a third larger than females. The body of the platypus is squat, short-legged; the tail is flattened, similar to the tail of a beaver, but covered with hair, which noticeably thins with age. In the tail of the platypus, like the Tasmanian devil, reserves of fat are deposited. Its fur is thick, soft, usually dark brown on the back and reddish or gray on the belly.

Slide 9

Ostrich Emu

The emu is a large flightless Australian bird of the causaridae order. Previously, emus were classified as ostrich-like, but in the 1980s the classification was revised.

Slide 10

The meerkat is a species of mammal from the mongoose family. Distributed in South Africa, mainly in the Kalahari Desert: in the territories of southwestern Angola, Namibia, Botswana and South Africa, they were previously noticed in Madagascar.

Slide 11

Flora in Australia

Since the Australian continent for a long time, starting from the mid-Cretaceous period, was isolated from other parts of the globe, its flora is very unique. Of the 12 thousand species of higher plants, more than 9 thousand are endemic, that is, they grow only on the Australian continent. Endemics include many species of eucalyptus and acacia, the most typical plant families of Australia. At the same time, there are also plants here that are native to South America (for example, southern beech), South Africa (representatives of the Proteaceae family) and the islands of the Malay Archipelago (ficus, pandanus, etc.). This indicates that many millions of years ago there were land connections between the continents. In general, Australia's forest resources are small. The total area of ​​forest, including special stands consisting mainly of softwood species (mainly radiata pine), accounted for only 5.6% of Australia in the late 1970s. The first colonists did not find plant species characteristic of Europe on the mainland. Subsequently, European and other species of trees, shrubs and grasses were introduced to Australia. Grapes, cotton, grains (wheat, barley, oats, rice, corn, etc.), vegetables, many fruit trees, etc. are well established here.

Large kangaroos live up to 16 years. The emu is the second component of the Australian coat of arms. The emu is a human-sized bird that runs faster than a horse, and the kick of its foot is no weaker than the kick of a horse's hoof.
• The platypus is an oviparous mammal with a wide, flat beak that strains food in the water. It has five-toed feet with webbed tissue and thick dark brown fur. The hatchlings are naked and blind, 2.5 cm long. It feeds on worms, crayfish, and eggs. Leads a nocturnal lifestyle.
• The bottle tree has an original bottle trunk, in which a large amount of moisture accumulates, which is consumed during the dry season. Tree height 15 m, dense crown with narrow leaves.
• There are 500 species of eucalyptus in Australia that grow in dry river beds. The height is more than 100 m, and the roots go 30 m deep, which is why they are called “living pumps”. The leaves are arranged on an edge and the bark is shed from the trunk, and people call it the “shameless tree.”

The originality of the organic world of Australia Geography lesson in the 7th grade Geography and biology teacher of the municipal educational institution "General Educational School" in the village of Nebdino Timusheva N.V.

Goal: To create conditions for the formation of knowledge about the uniqueness of the organic world of Australia. Objectives: Educational: to contribute to the formation of knowledge about the endemics of Australia, the ability to establish cause-and-effect relationships in the uniqueness of the organic world in nature. Developmental: development of students’ cognitive activity, logical thinking, ability to analyze, compare, and draw conclusions. Educational: developing the ability to work in a team, the ability to assess the level of one’s knowledge, cultivate a sense of responsibility and empathy.

“...This region is the most curious on the entire globe! Its appearance, plants, animals, climate - all this surprised, surprises and will still surprise... The most bizarre, most illogical country that has ever existed!..” Jules Verne “The Children of Captain Grant”

Nature has created a huge reserve in Australia, where many plants and animals have been preserved, similar to those that inhabited the Earth in ancient times and disappeared on other continents.

Coat of arms of the Commonwealth of Australia The kangaroo is a symbol of Australia. His image, along with the image of an emu, adorns the country's coat of arms.

There are three types of giant kangaroos: gray kangaroos, the largest of the entire family, red or steppe kangaroos, slightly inferior in size to their gray relatives, and the smallest of the gigantic kangaroos - mountain ones. Family Kangaroo Red or steppe kangaroos Gray kangaroos

The second animal after the kangaroo depicted on the coat of arms of Australia. The emu is a large flightless Australian bird, the second largest bird in the world, after the African ostrich, it reaches 1.5-2 meters in height and weighs up to 60 kilograms.

Oviparous, or primal beasts This unique animal is one of the symbols of Australia; it appears on the reverse of the Australian 20 cent coin. The platypus gets its eloquent name from its soft beak covered with elastic skin. In appearance, the echida resembles porcupines. They have short, stiff hair on their body, as well as long spines located over the entire surface of their back. Echidnas feed their young with milk using pores in the milk field. platypus echidna

The koala or marsupial bear is the only species of the koala family. Koalas are endemic to Australia. Animals live on eucalyptus trees. They are only herbivores and true marsupials!

There are no trees in the world taller than eucalyptus trees. Their maximum height is 155 meters. Eucalyptus trees have over 600 species and varieties in their genus. One of the characteristic features of this tree is the specific smell of its leaves, secreted by essential oil glands, and different types of eucalyptus each give their own scent: lemon, rose, violet, lilac, mint, camphor, turpentine, laurel... They grow in their homeland, in Australia.

Bottle tree In Australia, this plant is very well adapted to heat, drought and lack of water. From a distance it looks like a giant bottle. Moisture accumulates in the trunk and is used up during drought.

Casuarina Casuarina is another plant most common to Australia. This is a strange-looking tree or shrub with thin, drooping shoots and no leaves. In appearance it resembles horsetail, and in the shape of the crown it is similar to spruce. This is what they call it - the “Christmas tree”. The thin shoots of casuarinas resemble the hair-like fine feathers of cassowaries, large running birds that live near casuarinas. Because of its very durable, bright red wood, casuarina is also called “iron wood.”

Marsupial or Tasmanian devil Family Marsupials of carnivores. Body length 52-80 cm, tail 23-30 cm. Lives in forests, active at night, during the day hiding in crevices among stones, in voids under fallen trees. Feeds on various vertebrates. This beast is not just a predator, but truly a devil in the flesh. He is angry to the point of rage and even the sounds that the marsupial devil makes are similar to a roar with some kind of creepy cough. Body length 52-80 cm, tail 23-30 cm.

Dingo is a secondarily feral domestic dog, the only placental predator in the aboriginal fauna of Australia.

Wombats are a family of two-incisor marsupials native to Australia. Wombats are burrowing herbivores that resemble small bears in appearance.

About 350 species of birds are endemic Lyrebird or lyre bird Laughing kookaburra

Australian crocodile On the Australian continent, the most common species is the Australian Johnston's crocodile, or Australian narrow-snouted crocodile. These reptiles have a short body length - up to three meters. Australian freshwater crocodiles do not hunt people, and even with an accidental bite, a person does not face particularly serious injuries.

Australia is famous for its great abundance of amphibians, especially frogs. 93% of the 5,280 frog species are endemic. Of these, the family of Australian toads, the genus of Australian tree frogs, etc. should be noted. Australian blue tree frog

Natural areas of Australia

Conclusions: The Australian mainland has been isolated from other continents for a long time. Here, in a favorable climate, unique ecosystems with species of plants and animals unique to them were formed. The species composition of plants and animals is poor and unique. Of the 12 thousand species, about 9 thousand are endemic! Among flowering plants, 85% are endemic, among mammals – 84%, and coastal fish are almost all unique – 90%! It’s not for nothing that Australia is called a continent-reserve. Australians take good care of their nature.
