The important thing about a pond is that it is full of water. Water keeps fish and turtles alive and comfortable, water helps plants and trees grow, and animals use water for drinking. The importance of ponds for biodiversity has only been understood recently. Research has found that biodiversity and abundance of invertebrates is greater in ponds than in rivers.
Frogs, toads, and newts use small ponds to breed, while large ponds can house waterfowl, including mallards, moorhens, and coots. The gray heron also regularly visits even the smallest ponds, feeding on fish and amphibians. Ponds tend to be, by definition, rather shallow bodies of water with varying abundances of aquatic plants and animals. Depth, seasonal variations in water level, nutrient flows, amount of light reaching ponds, shape, presence of large visiting mammals, composition of any fish community, and salinity can affect the types of plant and animal communities present.
Food webs are based on both free-floating algae and aquatic plants. There is generally a diverse variety of aquatic life, with some examples including algae, snails, fish, beetles, water bugs, frogs, turtles, otters, and muskrats. Major predators may include big fish, herons, or alligators. Since fish are the main predators of amphibian larvae, ponds that dry out each year, thus killing resident fish, provide important shelters for amphibian breeding.
Ponds that dry out completely each year are often referred to as spring pools. Some ponds are produced by animal activity, including lizards and beaver ponds, and these add significant diversity to landscapes. Other photosynthetic organisms, such as phytoplankton (suspended algae) and periphytons (organisms that include cyanobacteria, debris and other microbes) thrive here and are the main producers of pond food webs. Keep in mind that the more natural you maintain your pond and actually work to create an ecosystem, the less likely you are to need chemicals, as a natural and diverse system is better equipped to care for itself.
Some regions of the United States define a pond as a body of water with an area of less than 10 acres (4.0 ha). For manufactured ponds created for aesthetic reasons, such as those found on golf courses, lower silt production will maintain water clarity. With this in mind, your pond can provide a much-needed habitat area for them to stop on their journey, so don't be surprised if you see deer, foxes, or even larger creatures like pumas and bears passing by. Many ponds have been created by people, however, there are many examples of ponds that have been sculpted by nature, for example, by winding rivers or eroding glaciers, or by the fall of a tree, leaving the root pit exposed, or even by the action of animals, such as wild boar.
It should come as no surprise that mammals also stop at their pond to drink and possibly eat some food, whether it's grasses and other vegetation or eat things like insects, herpes, or birds. Spring ponds of natural origin do not usually have fish, a major consumer of higher tropics, as these ponds often dry out. Lining Your Pond Pond liners are the ideal solution for creating a biodiversity rich and sustainable pond. Orogenies and other tectonic uplift events have created some of the oldest lakes and ponds in the world.
Conversely, if a pond system has other species, such as leeches or invasive plants, the surrounding area is likely to degrade and contaminate (and therefore drain into the pond), as they tend to be species found in contaminated areas rather than in clean and healthy areas. Over the past 10 years, we have begun creating networks of new ponds as part of the Million Ponds project, with the ultimate goal of returning to the million ponds that once enriched the British landscape 100 years ago. Ponds are found in gardens, cities and towns, fields on farmland, floodplains and heathlands; in forests, grasslands and moors. These ponds were fed with rainwater, water that entered through the canals, their own springs, or a combination of these sources.
As a result, some organizations and researchers have decided on technical definitions of pond and lake that are based solely on size. . .
