What is an invasive species? How to control their outbreak?

Are you wondering, what is an invasive species? Well, an invasive species is defined in the USA as the alien species which causes environmental and economic harm. It harms the human health as well. They are non-native species that get added to the community through the natural range extension or through any human activity. Nevertheless, non-native species have a harmful effect on our ecosystem and our ecology. You must know about the ways of controlling their population or spread.

What Is An Invasive Species

Why are the invasive species dangerous?

Perhaps, the invasive species are the major threat to our natural surrounding and environment. This is due to the following reasons:

•    They may alter our ecosystem function and our habitats.

•    Invasive species are competitive and can crowd a space while replacing the other species that forms the part of our ecosystem.

•    They can damage the human activities while costing our economy millions of dollars.

•    Invasive species rank just second in the realm of habitat destruction. They pose a major threat to our biodiversity.

•    Invasive species are leading disease carriers to destroy the crops and harm the human health. They act as competitors to alter the habitat and tend to hybridize with the local species.

•    When compared to pollution, diseases and harvest, the invasive species are major threats.

Tips on controlling invasive species

By now it is already clear, What Is An Invasive Species and how they are dangerous. Let us now find out the ways of controlling them:

•    If you are looking for a cost efficient way of controlling the invasive species, you may keep them out in the first place. The damaging invaders must be kept out. It is possible to reduce the ability of the silent invaders to invade the place, if you are pretty careful about their invasion pathways like the wooden packing material, the shop ballast water and the horticulture plants.

•    It is good to discover the invasive species earlier. If discovered at an early stage, it becomes far easier to get rid of them. Even if it is impossible to totally eliminate the invaders, still you can keep a check on their population.

•    Well, the best way of reducing the population of invasive species is by introducing an enemy of the species. This is called the process of biological control. You can introduce a predator, some parasite or a disease and competitor to combat them. Try and introduce a natural enemy from the native range of pests. This will be far more effective.

•    If you are looking for the most direct way of controlling the invasive species, you can use the chemical solutions. This process is known as chemical control whereby you use the chemical sprays and chemical pesticides to directly target the species to eliminate them.

•    Human effort and machinery can be used together to get rid of the invasive species.

Thus, we can say that there are various ways of controlling the invasive species and reducing their population. It is rightly proclaimed that prevention is better than cure. Thus, by being careful about the surroundings, one can keep a check on the invasive species.

What is an invasive species and what are the factors that make it invasive?

An invasive species is the non-native organism which poses serious threat to our ecology, to the economy, to the environment and to the human health. There are many who get confused about What Is An Invasive Species. They wonder if they are plants, viruses or some organisms. In fact, an invasive species may be an animal, microorganisms and even some kind of plants. In all the invasive species, one thing is common that they usurp the general habitat of the life forms native to the place. They are competitive and invasive species that lead to the decline in the overall population of general species. Thus, we can say that such species are hazardous and pose a serious threat to the wellbeing of other species of animals and plants. Such invasive species of animals or plants or microorganisms may be introduced either intentionally or accidentally by the human acts. Such organisms are the source of real nuisance to the place. There are various factors that make such species too much invasive.

What Is An Invasive Species

What makes the invasive species invasive?

In fact, the invasive species are very adaptive, competitive and even successful at reproducing. Thus, we may say that they spread at an alarming rate. The leading cause of their outbreak is the lack of predators in a space to keep the invasive species in check. If the environment is new and lacks predators, nothing can stop the invasive species from spreading. A predatory species can be the part of a stable eco system since the prey animals have got accustomed to deal with the predators. But, if the environment is new and the predator lacks adaptations, it may start to threaten other living creatures. So, the problem begins and it may happen that other organisms become extinct.

How do the invasive species spread?

Organisms may spread outside the native habitat through travel and trade. Invasive species like some kind of fungi, insects, and microorganisms may arrive along with vegetables and fruits. They may arrive on houseplants, gardens or in the soil carried with the items. People can unknowingly carry the microorganisms, plant seeds from one region to another. Even the ships may carry the entire host of harmful life forms, marine organisms that may just cling to the sides. Small mammals like rats and rodents may also be considered invasive species. Any animal which is allowed to breed outside its original environment becomes a major threat. Plants and animals that have been brought to a new place for agricultural purpose become major pests. They may be animals, plants or other species like the viruses.

How harmful is the invasive species?

It is already estimated by now that almost half of the endangered species of animals and plants coming around to 39% plants and 57% animals are declining. This is all due to the invasive species.

You should take necessary steps to prevent the spread of invasive species. There is no particular answer for what is an invasive species. The species may be anything that threatens other organisms.
