Throughout the world there are thousands of rivers, lakes and wetlands, vegetation which is impressive in its diversity.However, some plants can exist not only above the water surface but also below it.All plants freshwater reservoirs are unique, but despite the fact that most of them still characteristically grow in certain types of reservoirs, there are also a species that thrive in any fresh water.

As an example, a conventional shamrock is a valuable medicinal plant.Its stalks begin to grow directly from the root, each of these three major crown sheet.At the same time at the stem leaves are completely absent, but its top is crowned with a brush of small pale pink, almost white flowers, resembling the shape of its stars.

most common plants in freshwater ponds

plants freshwater reservoirs, the names of which are listed in this article are growing almost everywhere, however, have a number of individual features.For example, plants that can be seen almost everywhere where there is fresh water - a bulrush, cattails and reeds.

They like to grow thickets and have many similar features, due to which they are often confused with each other, even though they belong to different families.This primarily stems from these plants are tall and straight.In some cases, it can even reach 6-9 meters, but that is where the similarity ends.In the reeds on the stem is almost no leaves, from cattail leaves begin to twist spirally from the base already.In addition, the ear of cattail long and velvety, unlike the cane, which is characterized by fluffy panicle.

practical use

For plants such as bulrush, cattails and reeds, characteristic rapid growth, due to which their number increases so that they fully capture significant portions of water, they gradually emptying.Largely due to the fact that people from ancient times adapted plants freshwater reservoirs for different household needs, particularly for roofing, weaving baskets, bags, mats and even ropes, sources of fresh water almost dry.The remaining plants simply do not have time to absorb all the moisture and dry up the source.

Marshland

In order to find out which plants freshwater reservoirs are characteristic for your area, you need to carefully examine the closest to your sources.For example, the most widespread in the marshland had sedge grass, which has more than 1,000 different species worldwide.Nevertheless, the structure of each of them there are similar characteristics, among which - trihedral stem dense structure, while moving away from each face of the long groove-shaped leaves, pointed end.This structure leaves can be observed in most cereals.

second most common and the most similar in appearance to a plant sedge rushes.It also grows in swamps, but for this herb, unlike sedges typical round structure of the stem.In addition, due to the fact that stem from Sitnik and thinner branches, leaves, retaining a similar structure, yet much narrower than that of sedge and saw these two plants close, mix them in the future will be difficult.

rivers and lakes

freshwater plants that are characteristic of the river and lake areas, especially noticeable on the banks.The first is typical of the iris flower that looks similar to an ordinary garden iris.Apart from these, in the coastal area can not grow less common crybaby-grass, whose purple florets resembling spike, immediately catch the eye.She leaves her like a willow, but they are characterized by a special slit through which excessive moisture, which absorbs plant easily discharged to the outside.

Poisonous representatives

However, it should be borne in mind that not all plants freshwater reservoirs are harmless, because some of them are poisonous and representatives, among which the most common alisma and arrowhead.Thus the appearance of the leaves is directly linked to their habitats.In the event that these plants grow submerged in the water, the leaves will remind its shape tape.If they are placed on a water surface, then retained therein by means of a special underwater petiole and floating plate.Also, being on the surface of the leaves acquire arrowhead shape of arrows and start to fully live up to its name.Unlike alisma that is entirely poisonous, people have adapted arrowhead tubers for food.

freshwater plants that are typical of marshland - and buttercups is also characterized by the shape of the leaves, which can be both floating and placed under water.Thus, despite the fact that they can be found in other fresh water sources, all without exception buttercup are poisonous plants.The most dangerous to humans are:

  • buttercup poison;
  • buttercup-banewort - forms on the skin abscesses.

In addition, in the category of poisonous plants that are found in freshwater reservoirs, include one of the most poisonous plants in the modern flora - hemlock, which grows exclusively in swampy areas.

Beauty freshwater plants

freshwater plants, photos of which can be seen in this article, continue to surprise with its beauty.For example, seeing a white lily in the pond, few people will remain indifferent to her elegance.Flowers in her big, big.

revealing at sunrise, they are closed only at sunset.The people lily received several names, among which the most famous are the white water lily and rose.Its leaves are above the water, big, big.They are characterized by the presence of a large number of air cavities, but her underwater leaves resemble ribbons.Often, freshwater ponds can be found and no less beautiful yellow water lily.

Plants and animals are unique freshwater and in need of constant protection.Due to the constantly changing climatic conditions, some of them are on the verge of extinction, and the rest have significantly reduced their population.The only exception is the amphibious buckwheat, which in the case of drying pond water clears leaves and grows a new, peculiar to terrestrial plants.

However, in contrast to the amphibious buckwheat, can give an example of pondweed, which grows exclusively in deep water, and is a favorite destination for the majority of spawning fish.Some farm import it specially imported to significantly increase the fish population.

person should by all means try to maintain the ecological situation of freshwater reservoirs, reducing emissions, not only in water sources, but also the atmosphere, and to the extent possible to reduce the population of various plants, reducing the moisture content of water bodies and ultimately lead to theircomplete drainage.
