What is a native species?

Native species is an organism that lives in the area for quite natural reasons without human intervention. It can be because the body has evolved in this environment or could be brought there by natural causes. For example, the wind can spread plant seeds widely and species can be transmitted by animals or birds; Individuals can also migrate search for food or territory. On the other hand, a non -native species was intentionally or accidentally introduced by human intentionally or accidentally, and can become invasive, taking over the natural environment and suffocation of native species. Invasive species often develop quickly and spread aggressively, making it difficult to compete. They can also develop subspecies that have improved to use fine variations in the environment, and some of them can eventually develop on new species. However, this IncD Specialization can provide the organism less able to cope with changes in its environment

Endemic and indigenous species

are recognized two types of native species: endemic species occur only in the area in question, while native species also naturally occur in other areas. Endemic organisms are particularly vulnerable to extinction because they can be limited to a very small area and to a specific station in the region. They could develop in a very specialized way, adapt to an unusual and unusual environment and can only be survived to a very limited extent of conditions.

The populations of indigenous organisms tend to be more robust because they are more widespread. They have usually developed so that they are doing well in habitats that are quite common or can adapt to a wide range of conditions. Sometimes the recollooblasts of the nize from which they have disappeared, and in some cases they have been re -established by people.

One of the reasons why the organism is native of the area is that it has evolved there. This is most often seen on the islands where SRThe ovable insulation allows unique species to develop for a longer period of time. The islands tend to have many endemic species and their significant ecology are very vulnerable. When the island environment is disturbed, the native species have found that nowhere else can be extinct.

spread of indigenous species

indigenous species may have evolved in the station where they are located, or they could arrive in a natural way from anywhere. Since the organisms have evolved to match the evolutionary alcove, they will expand to other areas where these niches remain unoccupied if they have resources. The transport of plants and seedlings may occur on wind currents, bodies and abdomen of animals in the natural natural reach and due to the release of shoots and runners. For example, the type of plant may eventually end up covering very large areas.

Animals

Animals naturally spread, as their populations increase and move further in finding food and territory. Native animalsThey can follow seasonal migration formulas or can regularly move their populations in response to different pressures, natural curiosity or changing landscape. Some animals travel long distances in finding a new territory; Some bird and insect species are particularly remarkable for their lengthy migration.

threats for native types

native species face different threats of survival and some are critically endangered as a result of human activities. In the last few centuries, many animals and birds have been lost because it was hunted to extract. Currently, the destruction of habitats is the main threat, because more land is built or used for agriculture.

Native species protection

The recognition of the importance of native species and unique environments has led to a number of organizations that promote original plants and animals. The International Union for Nature Conservation (IUCN) maintains lists of endangered and critically endangered species and campaigns to protect their fromAyms. World Wide Fund for Nature (WWF), formerly known as the World Wilderness Fund, helps to preserve the habitat of original animals, plants and other organisms and leads adoption campaigns for endangered animals. At local level, there are many organizations that encourage people to use indigenous plants in their gardens, participate in eradication campaigns for invasive organisms, and educate people about the risks for native animal species that represent imported livestock and pets.
