What is an indicator?

indicator species or bioindicator is a plant or animal species used to collect information about the environment or area. The presence of an indicator species can be a signal, as well as the absence of such a species, and in cases where indicator species are present, their relative abundance and health can also be used as an indicator. Numerous species of plants and animals are used as indicators, along with organisms such as lichens and fungi, in the environments from mountain to continental shelf. For example, a certain type of tree can only grow in a very specific area, or a specific mammal can only roam in a particular area. If the species begins to disappear, it can be said that the ecoregion is shrinking and it can raise concerns about the health of the environment in this area. Numerous organizations monitor the presence of species of indicators, especially in vulnerable Aujuk to see if the habitat is reduced or damaged.

These species can also generally be used to collect environmental information. Some types of indicators are selected specifically because they are extremely sensitive to pollution or human intervention, so scientists watching these species can identify problems in time. Others may illustrate, indicating the presence of the disease that needs to be addressed or may migrate or develop stress behavior in response to climate change. All these changes in the natural order can be observed and monitored to monitor the environment.

The types

indicators were historically used to collect information on the geological composition of many regions. For example, some plants grow abundantly in the presence of specific minerals, so the presence of such plants may be a sign that this may be abundant. Other plants such as wet, marshy soil, indicating the presence of water source when they are abundant. It was also known that some plants change color in response toThe presence of specific minerals and chemicals.

Scientists determine which species in the region are species of indicators based on field research, historical records and known information about these species. If the government agency uses an indicator, it usually documents the processing process carefully, if the decision made on the type of indicator is questioned by other agencies or citizens.
