Presentation on the topic: Natural community. Swamp. Plant communities of meadows, swamps and water bodies Reports on natural communities lake swamp field
The swamp is a natural community widespread in our country. Look at the physical map of Russia: what a significant area the swamps occupy. Wet place, hummocks, bog, reed thickets, rare bushes.
How was the swamp formed? Once upon a time there was a small lake in this place, which did not have a runoff, its banks were quickly overgrown with reeds and cattails. Water lilies and lilies rose from the bottom. Every year, reeds and reeds grew, more and more protruded from the banks to the water, intertwined with stems, closing the water, mosses settled on the stems, they absorbed moisture and the water stagnated. Several decades passed, and the plants completely captured the lake and closed the water. Every year the thickets became thicker. And now a thick layer has formed almost to the very bottom. That is why, when you walk through the swamp, the bumps are so springy, your legs get stuck, just look - you will fail. Maybe the forest stream flowed slowly and gradually overgrown with herbs in the lowlands, or a spring spouted from the ground and soaked everything around with water. That's how water piggy banks appeared in these places - swamps.
A lot of water means that moisture-loving grasses and shrubs began to grow, and animals with birds settle down such as you can only see in the swamp. The surface of some swamps is densely covered with mosses. Especially a lot of water is able to absorb sphagnum moss, which means “sponge” in Greek (Fig. 2).
Sphagnum has a special ability to kill microbes. Therefore, the remains of dead organisms are not completely processed, they accumulate under a layer of moss, compact, and as a result, peat is formed - a combustible mineral. Peat thickness can reach 3-4 meters or more. It is on this peat cushion that other inhabitants of the swamp live. Peat is very saturated with water, and it contains almost no oxygen necessary for the respiration of the roots. Therefore, only a few plants can grow in swamps. Most often, wild rosemary, sedge, and cranberries settle on a thick carpet of moss (Fig. 3-5).
Rice. 3. Marsh rosemary ()
Among swamp plants, cranberries are especially valued. People have been collecting this healing berry for a long time. In addition to cranberries, other tasty berries grow in swamps: blueberries (Fig. 6), cloudberries.
Rice. 6. Blueberry ()
Such herbaceous plants as cotton grass, reed, calamus, bulrush and cattail have adapted to the swamps (Fig. 7, 8).
The cattail has large, dark brown heads that are densely built of raw hairs. Seeds ripen under the hairs, in autumn, when the seeds ripen, the hairs dry out and the head itself becomes very light. You touch it - and light fluff flies around you. On parachutes, cattail seeds scatter in different directions. Even in the last century, life jackets were made from this fluff. And a round packing fabric was made from the stalk of cattail.
Unusual plants are also found in the swamps. Sundew (Fig. 9) and pemphigus are predatory plants.
Sundew catches and eats insects. Insects are fast and mobile, how can this plant threaten them? The small leaves of sundew are covered with small hairs and droplets of sticky juice, similar to dew, which is why the plant was called sundew. The bright color of the leaves and droplets attract insects, but as soon as a mosquito or fly sits on a plant, it immediately sticks to it. The leaf shrinks, and its sticky hairs suck out all the juices from the insect. Why did the sundew turn into a predator plant? Because on poor marshy soils, it lacks nutrients. A day sundew is able to swallow and digest up to 25 mosquitoes.
In a similar way, the Venus flytrap catches prey (Fig. 10).
Rice. 10. Venus flytrap ()
It has leaflets that close like jaws when one touches the hairs on the surface of the leaves. Since these plants are rare, they need to be protected.
Another trap was invented by pemphigus, they named this plant for the sticky green bubbles that densely cover its thin, thread-like leaves (Fig. 11, 12).
Rice. 11. Vesicles of pemphigus ()
Rice. 12. Pemphigus ()
All the leaves of the plant are in water, there are no roots, and only a thin stalk with yellow flowers rises above the surface. The plant needs bubbles for hunting, and this grass hunts for aquatic inhabitants: small crustaceans, water fleas, ciliates. Each bubble is a cunningly arranged trap and at the same time a digestive organ. A special door closes the vial until some creature touches the hairs of this hole. Then the valve opens and the bubble sucks in the prey. You can't get out of the bubble, the valve, like a door to a room, opens only in one direction. Inside the bubble are glands that produce digestive juice. In this juice, the prey is dissolved and then absorbed by the plant. Bladderwort is very gluttonous. After about 20 minutes, the bubble is ready to capture a new victim.
How did the animals of the swamps adapt to life in wet places? Among the inhabitants of the swamps, a frog is known. The dampness helps the frogs keep their skin constantly moist, and the abundance of mosquitoes provides them with food. Beavers (Fig. 13), water rats settle on the swampy banks of the rivers, you can see the snake and the swamp viper.
Have you heard the saying: "Every sandpiper praises his swamp"? Kulik is a slender bird, similar to a seagull. This bird has protective plumage; with its long beak, the sandpiper finds mosquito larvae hiding there in the mud (Fig. 14).
Often in the swamps you can meet herons (Fig. 15) and cranes (Fig. 16), these birds have long and thin legs, this allows them to walk through the cold mud without falling through.
Herons and cranes feed on frogs, molluscs, worms, which are abundant in the swamp. White partridges like to feast on sweet berries in the swamp, and moose and roe deer like to eat juicy parts of plants.
In the evenings and nights, someone's roar is heard in the swamp, reminiscent of the roar of a bull. What people didn't say about it! As if the water one is screaming or the goblin quarreled with him. Who roars and laughs in the swamp? A small-sized bittern bird roars and hoots terribly (Fig. 17).
The bittern has a very loud cry, spreading for 2-3 kilometers in the vicinity. Bittern lives in reed beds, in reeds. Bittern hunts for crucians, perches, pikes, frogs and tadpoles. For hours, the bittern stands motionless in the thickets near the water and suddenly throws its beak, sharp as a dagger, with lightning speed - and the fish cannot escape. You start looking for a bittern in the swamp - and you will pass by. She will raise her beak vertically, stretch her neck, and you will never distinguish it from a bunch of dry grass or reeds.
But not only the bittern screams at night in the swamp. Here is a bird of prey eagle owl sitting on a branch. It is almost 80 centimeters long (Fig. 18).
This is a night robber and there is no salvation from him for either birds or rodents. This is how he laughs in the swamp when it gets dark.
Residents of swampy places sometimes at night can watch an amazing spectacle of many bluish lights dancing in the swamp. What is it? Researchers have not yet come to a consensus on this issue. Maybe it's swamp gas igniting. Its clouds will come to the surface and light up in the air.
People have been afraid of swamps for a long time. They sought to drain and use the land for pastures and fields, and thus thought that they were helping nature. Is it so? The swamp is of great benefit. First, it is a natural reservoir of fresh water. Streams flowing from swamps feed large rivers and lakes. When it rains, the mosses of the swamps absorb excess moisture like sponges. And in dry years they save water bodies from drying out. Therefore, often after draining the swamps, rivers and lakes become shallow. The Vasyugan swamp is one of the largest swamps in the world, its area is larger than that of Switzerland (Fig. 19).
Rice. 19. Vasyugan swamp ()
Located between the rivers Ob and Irtysh. The Vasyugan River originates in this swamp. Rivers such as the Volga, Dnieper, Moskva River also flow from swamps. Secondly, swamps are wonderful natural filters. The water in them passes through thickets of plants, a thick layer of peat and is freed from dust, harmful substances, pathogenic microbes. Clean water flows into the rivers from the swamps. Thirdly, valuable berry plants grow in swamps: cranberries, cloudberries, blueberries. They contain sugar, vitamins and minerals. Medicinal plants also grow in the swamps. For example, during the Great Patriotic War, sphagnum moss was used as a dressing for the rapid healing of wounds. Sundew is used to treat colds and coughs. In addition, the swamp is a natural peat factory, which is used both as a fuel and as a fertilizer.
Remember: you can not approach the wetlands and peat developments in the swamp! It is very dangerous.
Bears, deer, wild boars, elk, roe deer come to the swamps, which also find food for themselves here.
The swamp is the same necessary part of nature as forests and meadows, they also need to be protected. The destruction of swamps will lead to a change in nature on the entire planet. At present, 150 swamps of Russia have been taken under protection.
Today in the lesson you gained new knowledge about the swamp as a natural community and got to know its inhabitants.

SWAMP
A swamp is a plant community composed of perennial plants that can grow in conditions of abundant moisture by flowing or stagnant waters and reduced aeration of the substrate. The swamps are diverse in the way they appear, the conditions of existence, and differ from each other in their floristic composition. Higher spore plants can be dominants and edificators in swamps.
Swamp as a plant community
With swamps - plant communities confined to damp and moist soils, ideas about sedges, sphagnum moss, cranberries, blueberries, and cloudberries are associated. Such swamps are called grassy. Swamps covered with forest are called forest swamps.
Bogs with abundant growth of moss are called moss. If green mosses dominate, the swamp is called hypnotic, if sphagnum dominates - sphagnum.
In conditions of waterlogging, insufficient oxygen supply, with lower temperatures and increased acidity of the substrate, conditions are created that prevent the development of putrefactive aerobic bacteria.
Lowland swamps occur in the lower parts of the relief, where excess water accumulates and the territory becomes swamped.
Low-lying bogs are called bogs of mineral nutrition. Their soils are rich in mineral and organic matter. Plants use not only groundwater, but also atmospheric precipitation, and in the floodplain of rivers - the waters of spring floods. The swamps are diverse in their floristic composition; Settling plants have different life forms.
Grass marshes are often practically difficult to distinguish from waterlogged meadows, with which they are often connected by numerous crossings.
Transitional swamps represent the transition from lowland to raised marshes. They can occupy the most varied position in the relief.
A significant place in the vegetation of transitional swamps is occupied by sphagnum mosses, cotton grass, and sedges; from shrubs and shrubs - cranberries, blueberries, wild rosemary, marsh myrtle; from tree species - pine, fluffy birch.
Raised bogs arise as a result of swamping of land in conditions of weak evaporation of water and the presence of a waterproof layer of soil, with overgrowth and peat formation in reservoirs and in the place of lowland bogs.
In the raised bog, sphagnum is dominant, which grows profusely and determines the conditions of existence for other plants.
Plants of raised bogs are isolated from the soil by a thick peat layer, they live in poor conditions of mineral nutrition and increased acidity of the substrate. Blueberries and lingonberries are constant in the swamp, which are also characteristic of coniferous forests; blueberries also grow in swampy coniferous forests. Swamp shrubs and shrubs are characterized by a combination of hydro- and xeromorphic structural features. The xeromorphic signs of the inhabitants of the swamps are also explained by the poverty of mineral nutrition, especially nitrogen and phosphorus.
Green mosses also live in the raised bog, but their role is usually not great. Lichens can be found on the elevated parts of the swamp.
Economic importance of swamps.
Sphagnum peat is an excellent fuel. Many power plants run entirely on peat.
Sphagnum mosses can be used as a dressing to replace cotton wool.
In agriculture, peat is used as a fertilizer; peat pots and mulch are prepared from it; peat is used as a preservative and packaging material for the storage and transportation of fruits, vegetables, meat and other products.
Sphagnum bogs are of great scientific interest. Due to the peculiar ecological conditions of sphagnum bogs, the remains of plants and animals that lived on the land surface many years ago are well preserved in peat.
Sometimes traces of various historical cultures are found in peat layers. Therefore, sphagnum bogs represent an interesting "book" of nature.
Ideas about swamps as waste, useless lands are a thing of the past.
However, reclamation work should be carried out taking into account all natural complexes.

Preview:
World around 4th grade
Topic: The natural community is a swamp.
Goals: 1. To form an idea about the natural community - a swamp, the diversity of plants and animals of the swamp, about the relationship between them.
2. develop attention, ecological thinking, the ability to identify cause-and-effect relationships and dependencies, search for and highlight information, goal setting, planning.
3. foster a sense of responsibility for the preservation of the beauty and diversity of nature.
Lesson type:

During the classes:
Organizing time
What is the name of the section in the textbook we are studying? ("Journey Through Natural Communities")
What natural communities do we already know? (seas, oceans, lakes)
Do you think the natural community still exists?
And what is it called, you will find out by solving a crossword puzzle.
- Name the largest lake in Russia (Baikal)
- what lake plant does a person use as a building material? (cane)
- Name a rare beautiful lake bird (flamingo)
- A bug that runs on the surface of the water and hunts for midges and mosquitoes. (water strider)
- Waterfowl (duck)
- Small omnivorous lake fish (roach)
So what's the word? What natural community will we learn about today?
Read the topic of the lesson (slide 3)
Based on the topic, set learning objectives. What should you learn in class today?
So, today in the lesson we will find out: (slide 4)
1. What is a swamp?
2. What plants and animals live in the swamp?
3. What is the importance of swamps for nature and man?
New topic
1 .- What does a person represent with the word "swamp"? (dirt, bog, insects, etc.)
This is literally, but figuratively, what meaning do people put into this word? (something bad)
- So what is a swamp?(children's guesses) (bog slides)
Open textbook page 26 read 1 paragraph
So what is a swamp?
(A swamp is a special natural community that is formed due to excess water in the soil. (slide)
- What do you think, in what naturalswamps are most common in the zone? Why? (because there is a lot of moisture, tundra, forest - show on the map)
She prepared a short message for us about one of these places ... (a child’s message about the Vasyugan swamp
In the very center of the Siberian Federal District lies the Great Vasyugan Swamp. It is the largest swamp in the world. Its area is 53 thousand square kilometers. In such a space, the state of Switzerland would easily fit. Vasyugan swamp is located on the territory of the Tomsk region. It originated about nine thousand years ago. Initially, 19 separate swamps were located on its territory, which have now merged into a continuous water massif and the swamping process continues.)
- What did you learn from the message?
2.- What types of plants are found in swamps?(herbaceous: reed, sedge, reed, cattail; shrubs: rosemary, blueberry, cranberry - herbarium display)
What is the common property of all marsh plants? Why? (moisture-loving, because the soil is highly moistened)
She prepared a message for us about another such plant ... (child's message about moss)
(Almost the entire surface of the swamps is covered with moisture-loving plants. Moss is one of the most ancient plants, instead of roots they have small outgrowths with which they attach to the soil. What seems to us to be leaves, the moss actually has its branches, on which scales are located - Leaves Mosses do not bloom, reproduce by spores Mosses are green all year round Sphagnum moss turns white when there is a drought But if it rains, it will turn green again Moss can go without water for several years Can be used in construction villages, when laying log houses, moss is laid between the logs to insulate the dwelling.
During the war, doctors used moss instead of bandages and cotton. Moss pulled pus from wounds, disinfected them. So many Soviet soldiers were saved.)
- So what plant were you talking about?speech? What interesting things did you find out?
Fizminutka
Back to our plan, what's the next question we need to answer? (animals that live in swamps)
The swamp is a paradise for breeding various insects.
- What groups of animalsstill live in the swamp, we will find out from the textbook article on page 26 starting from paragraph 2 to page 27(independent reading)
Now open TPO on page 9 No. 15 . What do they propose to do?
Write out the representatives of these groups from the article you read.
- So name the representativesdifferent groups of animals living in swamps.
- What do you think, and on the territoryAre there swamps in our area? (area map)
How are swamps marked on the map? (dotted lines)
Look at the map of our region and tell me where swamps are most common?
(Bogs occupy 28% of the region's territory. They are widespread in the southeast within the Middle Amur lowland, as well as along riverbeds, penetrating into mountainous areas.)
3. - We came to the conclusion that a variety of living organisms live in swamps, but we need to find out how these organisms are related to each other. Make a food chain. (work in pairs)
- Think and say, can we break this relationship? What happens if one link is removed from the food chain?
Back to our plan, what is the third question we need to answer? (plan slide)
So, we got acquainted with the plants and animals of the swamps. Let's think about what role swamps play, do they need nature?
D / s you will find the answer to this question at home on page 28, and also discuss the meaning of swamps by completing the task in TPO on page 9 No. 16
Outcome: What are the learning objectives we set for ourselves today?
What new and unexpected things did you learn?
What is a swamp?
What common property do all marsh plants have?
What animals live in the swamp?
