Vegetable world.

Before settlement began, the territory of Chuvashia was covered with forests of spruce taiga, pine forests, multi-tiered oaks, and floodplain meadows. Only in the southeastern part and in Zasurye there were steppe areas.



Currently, forests have been preserved in less than one third of the republic, but in certain areas (Sumerlinsky, Ibresinsky, Alatyrsky) forests occupy more than 50% of the territory, and 1/3 of them are oak forests.

Dubravy.

Oak has a very durable wood with beautiful design in the section. He's on different economic needs was cut down from the moment the territory was settled, so the remaining oak forests of Chuvashia belong to the category of especially valuable forests. Linden, maple, elm, ash, forest apple, and rowan grow in the oak groves of Prisurye. And in damp places black alder grows. Larch, cedar and even Amur velvet are cultivated here. The shrubs of oak forests include black currant, viburnum, euonymus, hazel, etc.



Animal world.

The forests feature numerous species birds, reptiles, amphibians. Of the large wild animals and beasts, the most commercially important is the elk, whose weight reaches up to 400 kg. Behind last years Due to the ban on shooting, the number of moose has increased significantly. Their number exceeds 1000 heads. In the republic they live mainly in the Prisursky forests. Also in recent years, there has been a noticeable increase in the number of wild boars; badgers, erms, European minks, polecats, martens, raccoon dogs, foxes, hares and squirrels live here. The beaver was brought to Chuvashia. The Sura basin is home to the muskrat and the otter. Rivers are home to valuable commercial fish. Among the fish in the lakes and rivers of the republic, bream, shuk, sterlet, and subfish predominate; crucian carp and tench are also found. The number of many species depends on the quality of water, chemical composition bottom of the reservoir


At the border of aquatic and terrestrial ecosystems, special conditions are created in which amphibians live: frogs, newts, semi-aquatic animals (beaver, muskrat, mink), semi-aquatic birds (sea swallow, herons, gulls, terns, ducks, waders, etc.). It should be especially noted that the most ancient of Chuvashia’s mammals, the Russian muskrat, lives in the floodplain of the Sura River.

In the fields and meadows there are foxes, wolves, brown hare, polecat, gophers, hamsters and some other species, and among birds - lark, quail, lapwing and many others. Flycatchers, bullfinch, goldfinch, nightingale, blackbirds, magpies, rooks, jackdaws, crows, sparrows, pigeons, tits, etc. live in populated areas, parks and gardens.

A rare animal was discovered in Chuvashia, which is protected in international level. The Russian desman was spotted on a reservoir by Moscow scientists who came to our republic on an expedition.

Delegation from the Moscow Institute came to Chuvashia on an expedition and discovered a rare animal. The Russian desman was found at the end of September on one of the reservoirs located in the environmental protection zone. This was reported by the director of the Prisursky Nature Reserve, Evgeny Osmelkin.

This event is important because the number of muskrats is rapidly falling and the halo habitat can also be seen infrequently. IN last time she was seen in the Shumerlinsky district in 2001, reports Evgeniy Vitalievich. - Soon we will try to count the number of these animals on the territory of Chuvashia, I think we're talking about not about a hundred copies. For this, we may need underwater cameras, since the muskrat lives in bodies of water.

According to information free encyclopedia, youThe khukhol, or Russian muskrat, or khokhulya is a mammal of the mole family (order insectivores). The body is 18-22 centimeters long, the tail is the same, weight up to 520 grams. The muskrat leads a semi-aquatic lifestyle. Closed floodplain waters are the most favorable for muskrat habitat.em.

The desman is a rare endemic species listed in the Red Book of Russia with category 2: declining in numbers and rare relict species. Such factors as the deforestation of floodplain forests, pollution of water bodies where animals live, and drainage of floodplain lands have led to such a deplorable situation for the muskrat in Russia, the encyclopedia reports.

With the arrival of autumn Security inspectors have more work to do. The fact is that it is in the fall that state-protected animals can suffer from hunters. The reserve reminds that hunting is prohibited in the protected zone and the surrounding area. Employees constantly inspect the territory, record indicators in a log and, if poachers are detected, draw up protocols.

The territory of the reserve is inspected along certain routes, all observations are recorded in a special diary, and if this happens, inspectors draw up protocols that become the basis for administrative proceedings or are transferred to the police department to initiate administrative and criminal proceedings, reserve employees report.

By the way, October 14, in Chuvashia, as throughout Russia, the Day of Conservation Workers is celebrated in Russia. It appeared in the country in October 1999. Today workers of the Chuvash nature reserve "Prisursky" will celebrate their professional holiday After a working day, tea and cake.

How else can you save the muskrat from extinction and increase its numbers? Write in the comments under the news.

Thanks to 20 years of work The Prisursky Nature Reserve managed to restore the numbers and protect from extinction moose, bears, lynxes, wild boars, foxes, wolves, martens and other protected animals.

On the right bank of the Volga, in the delta of Sura and Sviyaga, there is a picturesque region - Chuvashia. Just imagine, 2,356 rivers and rivulets flow through an area of ​​18,300 km2. In addition, there are about 600 floodplain, 154 caste and interdune lakes. This aquatic diversity in combination with a temperate continental climate is favorable environment habitat for many plants and animals. The nature of Chuvashia is unique in its kind and is famous for its endless expanses. Only a third of the region is inhabited by forests. The abundance of beautiful corners and health resorts make Chuvashia attractive in the eyes of numerous tourists.

Climate of Chuvashia

As mentioned above, Chuvashia is located in, with distinct 4 seasons. average temperature In summer it fluctuates around +200C, in winter the thermometer rarely drops below - 130C. Such a gentle environment combined with mineral springs, clean air And species diversity and has long attracted people who want to significantly improve their health and enjoy the beauty.

Vegetable world

The flora of Chuvashia has undergone significant changes as a result of the global flora, which previously covered almost the entire territory of the region. Now they occupy only 33%, the rest is allocated for agricultural land. Despite the global nature of the situation, vegetable world Chuvashia pleases the eye and excites the imagination with a variety of colors.

The remaining forests are dominated by deciduous tree species, such as oak, birch, linden, maple, and ash. Coniferous trees include larch and cedar. Rose hips, viburnum, wood sorrel, blueberries and other shrubs have adapted to the undergrowth. There are a lot of mushrooms in the forests, which are collected on an industrial scale.

Chuvashia seem to be made for herbs! There are an incredible variety of them here! However, more often than others you can find feather grass, thickets of sage, bluegrass and fescue. One cannot ignore the plants that live in and near numerous bodies of water. The most beautiful inhabitants are yellow water lily and white water lily. Reeds, cattails, horsetails, sedges, foxtails and arrowheads cannot be called unattractive, their value is simply inversely proportional to their numbers.

Animal world

The fauna of Chuvashia has changed significantly under the influence of the same anthropogenic factor. Some species were completely destroyed, others were introduced artificially. And yet, nature prevailed with its versatility. Let's start from the heights and smoothly plunge into the aquatic environment.

Kites, hawks and swifts soar in the skies. Magpies, cuckoos, jays and owls nest on tree branches. A variety of small birds settle in - partridges, quails, larks. However, hunters are attracted more by grouse, hazel grouse, capercaillie and woodcock.

The forests are inhabited by wolves, foxes, hares, badgers, and martens. The creation of nature reserves and the ban on hunting allowed the population to increase brown bears, lynxes, wild boars and moose.

The steppe plains are inhabited by hedgehogs, jerboas, gophers, marmots, moles, hamsters, and other small rodents.

The reservoirs are inhabited by beavers, muskrats, otters, etc. The abundance of fish attracts ducks, herons, gulls and swallows.

Careful attitude towards wildlife— everyone’s feasible contribution to its revival.
