Vegetable world. Coniferous forests (taiga)
Presentation for a geography lesson in the 7th grade of a correctional school of the VIII type
Teacher – Funin Sergey Gennadievich
Slide 2
Taiga is a huge, wild and difficult-to-pass forest in which mainly coniferous trees grow. The word taiga means "dense forest". Taiga is located in the northern part of the forest zone and occupies 80% of its total area. Taiga is the oldest and snowiest part of Russian nature. Its width in the European part reaches 800 km, and in Western and Eastern Siberia – 2150 km.
Slide 3
Coniferous trees
Conifers are trees that have needles instead of leaves. The needles are also leaves, only of a special shape - long and narrow. They are able to survive the winter because they are quite durable. The waxy skin prevents the needles from drying out. The needles also provide the tree with the necessary amount of food in winter. These leaves live for several years. Then they turn brown and fall off. But not all at once, so the tree always retains foliage. Hence the name “evergreen”.
Slide 4
- Spruce is a tall evergreen tree (up to 30 m high) with a beautiful crown. Lives on average up to 250 - 300 years (sometimes up to 600). Spruce forests are very dense, dense, and dark. Spruce grows in damp places, and its roots are located shallow in the ground, so it can be found far to the north, even in areas where permafrost is located.
- Spruce is a frost-resistant plant.
- Spruce is one of the main symbols of the New Year and Christmas.
Slide 5
Pine is an evergreen, light-loving, large, resin-rich tree. Pine is very common throughout the north of European Russia and most of Siberia. Pure pine forests are called boron and usually grow on sandy soils and rocks. Pine is distinguished by flaky bark and a powerful root system. This tree is from 35 to 75 m high. The trunk is straight, the crown is raised high. Lives on average up to 350 years. Many types of pine are not afraid of snow, frost, drought, or winds. Pine extends farthest to the south of all coniferous trees; it can be found even in the Caucasus.
Slide 6
Larch is the most common tree species in Eastern Siberia.
Height – up to 35 meters. Lives 400 – 500 years.
This is a very cold-resistant tree. Having shed its soft, tender, light green needles for the winter, larch can withstand frost of -60 degrees. Larch, like spruce, has roots that penetrate shallowly into the ground, so it can grow in places where the soil thaws from ice by only 1 meter.
In the spring, the forest, consisting of larch, has a bright green color, and in the fall it acquires a golden-yellow color. In such a forest it is light, so many bushes and herbs grow there.
Larch
Slide 7
- Cedar is similar to pine, but its needles and cones are larger and its trunk is darker.
- The cedar has a spreading crown and a slender trunk with dark gray cracking bark.
- Cedar lives on average 350 – 400 years.
- Height – up to 60 meters.
- Cedar is the only tree in the Siberian taiga whose fruits are nuts. Its tasty and nutritious seeds - nuts - serve as the main food for many forest animals and a valuable food product for humans.

Description of the slides:
No. 1. Topic " Coniferous trees"
№ 2. Trees are called conifers, which have needles/needs instead of leaves. Needles are also leaves. Only a special shape - long and narrow. They are strong enough that they can easily survive the winter. The waxy skin prevents the needles from freezing or drying out. Needles also provide in winter tree the required amount of food. These leaves-needles live for several years. Then they turn brown and fall off. But not all at once, so tree the foliage is always preserved and they always remain green, hence the name - "evergreen".
No. 3. B coniferous In the forests of our district you can find spruce, pine, cedar, fir, and larch.
No. 4. Pine – conifer tree with a smooth yellow trunk. Pine needles are long and sit in pairs. Pine cones have a round shape.
No. 5. Spruce - familiar to everyone Christmas tree. Spruce needles are short, rough, located singly and densely cover the branches. The cones have an oblong shape. Ate - long-lived trees.
No. 6. Fir differs from spruce in that its needles are flat, and its cones stick up and even mature ones do not fall to the ground, but scales simply fall off them.
No. 7. Cedar pine is popularly called Siberian cedar. Its needles are collected in bunches of five, and the seeds are pine nuts.
No. 8. Larch is the only coniferous trees, which turns yellow and sheds its needles for the winter.
No. 9. Find out coniferous trees on twigs and cones.
№ 10. Coniferous trees and their use. Coniferous trees: larch, pine, spruce are the best material for construction. Larch and spruce are used in the production of furniture, parquet, and plywood. Pine is used in construction and mechanical engineering. Pencils are made only from cedar, and cedar oil for food is also made from pine nuts.
No. 11. Besides everything that coniferous trees give us oxygen. And also fruits coniferous trees– cones with seeds are food for birds and wild animals. That's why coniferous trees bring a lot of benefits and our task is to protect trees and all the nature around us!
