Wetlands of AHEC



A swamp is a forested wetland. Swamps are considered to be transition zones because both land and water play a role in creating this environment. It is characterized by excessive surface moisture, moisture-loving vegetation. Swamps and marshes are separated, and this difference is determined by the thickness of the peat cover: if the thickness of the peat is more than 30 cm, then it is considered a marsh, if less - a swamp. However, most people call any wetlands a swamp.
Swamps should be protected, studied and protected - this is a whole world, interesting and vital for nature and man!
Role, significance and types of wetlands
Swamps are a natural reservoir of water
During rain or snowmelt, swamps accumulate a huge amount of water, preventing it from quickly sliding into rivers, thereby preventing the occurrence of floods or significantly reducing their level. In the dry season, this accumulated water enters the rivers gradually, maintaining their level and not allowing them to dry out.

The swamp is a natural filter
An accumulation of partially decayed vegetation or organic matter (peat) in swamps effectively absorb pollutants, including heavy metals. Therefore, swamps purify all water from impurities and contaminants, making it suitable even for drinking. And the swamps attract and deposit all the dust from the surrounding area. Therefore, they purify not only the water, but also the air.

Swamps are "lungs of the planet"
Yes, these unpresentable ecosystems are 7-15 times more efficient at producing oxygen and absorbing carbon dioxide than forests. One hectare of swamp can absorb up to 1,800 kg of carbon dioxide per year and produce up to 700 kg of oxygen. Moreover, the carbon dioxide absorbed by swamp vegetation is stored for thousands of years in the form of peat and falls out of the global carbon turnover.

The swamps are home to animals and plants
Swamps are ecosystems with the highest level of biological diversity, surpassing boreal forests or steppes and competing with rainforests and seas. It is not only home to "wetland" species, such as waterfowl and semiaquatic birds, amphibians or fish. Swamps attract ungulates in the summer, which find here abundant food and good protection from predators. There are also predators in the swamps – foxes, badgers, raccoon dogs, which find food here – small rodents, fish, amphibians, eggs and bird nestlings. In late summer and autumn, the bear goes out to the swamps in search of berries for "fattening".

What are swamps like?
According to the type of landscape, the marshes are divided into upper, lower and transitional. Yes, swamps are not always lowlands filled with water, although they all start that way. But gradually deposited plant remains begin to raise the level of marsh vegetation. The "dome" of the upper swamp is formed, on top of which, in the center of the swamp, only plants survive. In the Far East, there is a very special type of swamp – Mari. These are wetlands formed on permafrost, which traps water on the surface. Tussock sedge are formed here – a special form of sedge in combination with sphagnum moss. Areas of depressed larch, dwarf birch and alder, thickets of blueberries, ledon and rhododendron.

Why do people need swamps?
Swamps bring a lot of gifts to a human - berries grow here-blueberries, cranberries, cranberries, cloudberries. The variety of animals makes the swamps valuable hunting grounds where you can get food. Peat serves as fuel and a valuable raw material for the chemical industry. Many plants that live in the swamp are used in the pharmaceutical industry. And for archaeologists, the marshes are a real treasure trove, where ancient artifacts are well preserved due to the high acidity of the environment. Handwritten birch scrolls of Ancient Novgorod, shields and swords of the Germans, Viking ships and almost all the archaeological finds of ancient Northern Europe were extracted from the swamps that preserved these artifacts for thousands of years.

What threatens the swamps?
Man still considers the marshes, if not the enemy, then a useless part of the territory that could be exploited with "greater benefit". Therefore, the main problem for the conservation of swamps is their drainage for further use in agriculture or peat extraction. As a result, there is a loss of animal habitats, a sharp change in the hydrological regime of streams and rivers, and an increase in the number of fires. Peat in drained swamps can burn for years, poisoning the air in the surrounding areas and regularly breaking through surface forest fires, as the fires in the Moscow region in 2010 showed.

Birds have a long neck, but without a distinctive bend, a dense and strong body and relatively short legs. Swans settle on the banks of calm and quiet rivers and lakes, bays and estuaries, less often choose swampy areas. They get all their food in water. Swans are very careful - they prefer to stay in open water and do not approach the shore. If possible, even the nest will be built on a small hummock away from the shore.

The fawns are born in late spring, and with the onset of autumn, the great migration of roe deer to the south begins with overcoming the main obstacle — the Nora River. The roe deer plowing the northern river has become a symbol of the Norskiy Nature Reserve. Mass crossing of roe deer is a unique sight.

Wetland conservation challenges


Hydroelectric construction
Most of the wetlands of the Amur-Heilong basin are located in the floodplain of this river or its tributaries. Their existence is closely related to the hydrological regime of this river. The construction of hydroelectric structures, especially "large" hydroelectric power plants on large tributaries of the river, significantly changes the natural flow of water in the rivers. In addition, hydroelectric dams deposit so-called sediment load in reservoirs, sand and soil particles that are constantly transported by rivers. In addition, the redistribution of annual sediment load negatively affects the breeding conditions of wetland animals, primarily many fish species.
Wildfires
Most of the wetlands of the Amur-Heilong ecoregion are subject to the annual impact of fires. Vegetation suffers from the burning of shallow roots and the death of fallen seeds. For animals, late spring fires are especially dangerous, as a result the clutches and nestlings of birds and animal’s cubs die. Autumn and winter fires lead to the destruction of the food supply of ungulates in the winter, which negatively affects their survival in these difficult natural conditions.
Wetlands drainage
This happens both as a result of the construction of hydroelectric structures (see the first point), and as a result of purposeful activities. For a long time, and even now, swamps are perceived by people as useless territories that could be used more usefully – for construction, agriculture or other purposes. The most affected are small areas of wetlands among the fields, the so-called estuaries, which are drained and completely plowed. At the same time, these areas play an important role in the nesting of white-naped and red-crowned cranes in the agricultural areas of the Amur-Heilong basin.
Pollution
Unfortunately, a significant part of the settlements equipped with centralized sewage systems, both in the Russian and Chinese parts of the Amur-Heilong basin, are still not equipped with treatment facilities that allow for sufficient purification of sewage water. Agricultural activities lead to contamination of wetlands with fertilizers and pesticides due to their flushing from the fields when the technology of their application is violated. A separate problem is the pollution of reservoirs, which are places of recreation for the population, and their coastal territories with solid household waste, primarily plastic.
Hunting, poaching and the disturbance factors
Hunting waterfowl during their migrations creates a significant disturbance factor for the birds, preventing them from resting and fattening up during migration stops. In addition to the waterfowl themselves, species that are not objects of hunting – cranes, oriental storks - are also of concern. Fish poaching with nets undermines the food supply of semiaquatic animals and birds, abandoned nets lead to the death of fish and waterfowl animals and birds, and are pollutants of water bodies.
Animals of Amur-Heilong
Living in the wetlands: Badger
The animal prefers to inhabit dry, dehydrated areas located near water bodies or swampy lowlands. This is due to the nature of the animal's diet, as it prefers to eat mouse-like rodents, lizards, frogs, birds and their eggs. And all the most delicious food either grows near the water, or lives near swamps and streams.

Living in the wetlands: Moose
The presence of wetlands is very important for moose habitats: Moose makes up for the lack of mineral salts and chemical elements, feeding on wetland vegetation, accumulating a supply for the winter, in the water, the mighty animal finds salvation from the summer heat, as well as from blood-sucking insects.

Living in the wetlands: Roe deer
The Asian roe deer is much larger than the European one. Most of the year, it lives sedentary on a plot of only 2-3 square kilometers, sometimes even less in winter. It likes to live near mares and grass swamps. Asian roe deer swim well and freely cross rivers such as the Amur-Heilong during their migrations. They feed on grass, as well as berries and mushrooms; in winter – branches, buds and dry leaves of trees and shrubs. They are very fond of acorns, which are sometimes even dug out from under the snow in winter.

Living in the wetlands: Japanese tree frog
The tree frog lives in well-warmed floodplains of large rivers, along the shores of lakes and in warm swamps. In the spring, in the habitats of this amphibian, you can hear "concerts" performed by male tree frogs. Although tree frogs are relatively small creatures, their singing is very loud due to their throat resonators. In standing warm water, the females lay their eggs in late May-June. These amphibians feed mainly on various insects and spiders.
