The expansive nature of invasive flora and fauna threatens the existence of native plant and animal species in their native habitats, changing the structure of habitats over time. The most sensitive species cannot compete and may even disappear. With the decline in biodiversity, the resilience of ecosystems reduces and thus the area will be more heavily impacted by various factors such as climate change and anthropogenic pressures.
What is an invasive species?
An invasive species is a species which, when it comes into a new environment where it is not native, can start to multiply rapidly, spread aggressively and overcome the native species thus threatening ecosystems, causing harm to nature and people.
Types of distribution
Invasive species are mainly spread by humans, often unintentionally. Climate change also plays a role. Rising average temperatures, changes in rainfall and intensity can affect the life cycles of some living organisms and their ability to move to new areas.
Threats to native species
Invasive species in many ways damage native flora and fauna. Indigenous wild plants and animals need time to develop resistance mechanisms. As a result, the native species are not able to compete with the rapid incoming of these invasive species in the struggle for food resources and space in their habitats.
