Invasive Alien Species: Disrupting and Changing the Normal Ecological Functions

Introduction Invasive alien species destroy and alter the normal ecological functions of biological cluster systems, ecosystems and biosphere as a whole (CBD, 2009). They pose a threat to biodiversity and may cause damage or even eradication to native circulation and native species dependent on other organisms. While destroying the flow of energy, converting food chains and ecosystem structures into nuclei, invading species not only create ecology but also influence the lives of almost all living things on earth, including humans. It creates problematic, economical and health problems. ,2009).

Introduction of non-native species in a region can damage the ecosystem and cause extinction of native species. This introduction can be called an alien species or invasive species. In some cases, invasive species compete with local species for food and feed on indigenous peoples. In other cases, a stable ecological balance may be affected by predation or other causes of unexpected species reduction. New species may also have diseases that are not resistant to native species.

Invasive alien species 21. Because invasive species become invasive species and can expand rapidly, if plants or animals of alien species or non-native species intentionally or unintentionally invade areas that are not normally found , It is a native species that could be a serious threat. 22. The client has not intentionally introduced a new alien species (currently not established in the country or territory of the project) unless it is based on existing regulatory framework. Nonetheless, customers are not deliberately introducing exotic species at risk of high intrusion behavior, whether or not the existing regulatory framework allows such introduction. The introduction of all alien species is subject to risk assessment (as part of customer's environmental and social risk and impact identification process) to determine the possibility of invasive behavior.

Invasion of alien invasive species, established and spread outside the normal distribution. Some of the most intimidating invasive species are cats and rats, silks, zebras mussels, African tulip trees, palm tree snakes and others. Introduction of alien species can occur intentionally or unintentionally, for example in organisms within "free riders" of organisms, boats, cars or soils. Because biodiversity is strongly influenced by climate change, special efforts have been made to minimize the adverse effects of other factors such as overfishing, loss of habitat and fragmentation, contamination, the spread of invasive alien species, etc. It is necessary to pay. In this way, we can make the ecosystem less vulnerable and better adapt to the growing threat caused by climate change.
