A pond is a cavity with small dimensions of natural or anthropic origin that is used for ornamental, recreational or conservation purposes. They are lentic ecosystems and there are natural, artificial, ornamental, agricultural or irrigation, etc. If you want to learn more about this topic, keep reading this interesting ecology article where we explain what a pond is, its characteristics, typesanimals and plants and what is it for.
What is a water pond?
A water pond is a small -dimensional water cavity, of natural or anthropic origin (built by the human being), which is used mainly for ornamental, recreational or biodiversity conservation purposes. They usually have little depth and can be found in gardens, parks, rural areas and even in natural ecosystems where they play a fundamental role for the survival of many species of living beings.
We advise you to read this other article about the bodies of water: what are, types and examples.
What are the characteristics of a pond?
- They are reduced size: ponds are much smaller than lakes and usually cover limited extensions.
- They have little depth: a frequent question that arises is how much depth a pond has? The answer is that the majority does not exceed 2 to 5 meters, which allows the entry of sunlight to the bottom and development of aquatic plants.
- The water is stagnant or has a slow movement: unlike rivers or streams where water runs, ponds have stagnant water or very slow motion, so they are considered lentic ecosystems.
- They constitute small biodiversity shelters: the ponds constitute ideal habitats for amphibians, birds, insects, aquatic plants and microorganisms, especially in areas close to large cities, where many species find a propitious site to feed and reproduce.
- They have a diverse origin: the ponds can be natural (formed by geological processes or accumulation of rainwater) or artificial (built by the human being for decorative or conservation purposes).
What types of ponds exist?
The ponds can be classified into different categories, here we present some examples:
- Natural ponds: Those that are formed spontaneously by natural processes in land depressions, fed by groundwater, rain or river overflows.
- Artificial ponds: built by the human being, very common in gardens, parks or farms.
- Ornamental ponds: designed for decorative purposes, often accompanied by aquatic plants, such as water lies, and fish, such as koi tents.
- Agricultural or irrigation ponds: used in rural areas to accumulate water and allocate it to crop irrigation or animal consumption.
- Piccolas ponds: destined for breeding and fish culture for consumption or repopulation. The ponds constitute the most common aquaculture systems, being able to vary from small, rudimentary, with gravity feeding equipment, until large ponds, built from machinery and that involve sophisticated water management. Tents and tilapia are widely cultivated and generally grow in fresh water ponds, while shrimp and more saline waters tolerant fish are grown in brackish water ponds.
- Retention or purification ponds: built to collect rainwater, reduce flood risks or filter pollutants before returning water to the natural environment.
What animals and plants live in a pond?
Ponds are ecosystems that house a wide variety of life. Each species finds conditions there that allow it to grow and develop, among them:
- Aquatic plants: species such as water lilies need calm waters and shallowness so that their floating leaves receive enough sunlight. Another example is the reeds and water lilies that require wet shores and flooded floors to fix their roots. In this other post you can know the aquatic plants: names and characteristics.
- Amphibians: frogs and toads depend on ponds with clean water and abundant vegetation, since these and other amphibians use the environment both to deposit their eggs and to protect themselves from predators.
- Aquatic insects: dragonflies and knights of the devil put their eggs in submerged plants stems; Their larvae need oxygenated waters to complete their development.
- Water birds: ducks and herons are looking for ponds with good availability of fish, insects or vegetation, since they use them as food and rest areas. Know more about aquatic birds: characteristics, types and names here.
- Fish: Many species require a certain quality of water and adequate oxygen levels; For example, tents are resistant and thrive in murky waters, while other more delicate fish species need clear and fresh waters.
What is a pond for?
The ponds fulfill multiple functions:
- Aesthetic and recreational: embellish gardens and parks, in addition to being rest spaces and contemplation. Here you can read about tips for good maintenance of your pond.
- Ecological: They serve as refuge, food and reproduction for multiple species.
- Educational: They allow the study of biodiversity and observation of small -scale aquatic ecosystems.
- PRODUCTIVE: They are used for irrigation, fish farming and animal supply in rural areas.
- Environmental: They help regulate the water cycle, retain rains and filter pollutants.
Frequent questions about ponds
What is the difference between a pond and a lake?
The main difference lies in size and depth. The lakes are much more extensive and deep, while the ponds are small and shallow.
In this link you can learn more about lakes: what are, characteristics and types.
How long does water last in a pond?
It depends on the origin and maintenance. In a natural pond, water can remain stable for years if there is a constant contribution of rain or groundwater. In artificial ponds, its duration depends on waterproofing, control of evaporation and periodic filling. In addition, the presence of aquatic plants helps maintain water for longer: floating species such as water lies or water lentils reduce evaporation by shade to the surface, while submerged plants contribute to oxygenate and balance the ecosystem, preventing water from deteriorating quickly.
What kind of water are there in a pond?
Normally, ponds contain fresh water, although in coastal areas or saline soils they can have brackish water.
