Invasive Species: A Very Short Introduction 014

Are invasive species the only ones that cause negative impacts? No, native species can also have negative impacts, such as termites.

 

　　How are invasive species made? This book presents the conditions under which invasive species become "detrimental" invasive species through three stages: "introduction," "establishment of populations," and "spread."

 

So what constitutes a detrimental impact? This is actually a judgment made from a human-centric perspective, which can be based on the benefits of agricultural development or evaluated from the value of biodiversity. This book includes various case studies, presenting ecological interactions that cause detrimental impacts.

 

The impact of invasive species is often far more severe than we might imagine. For example, after the invasion of shallow-rooted grasses, severe soil erosion occurs on riverbanks during heavy rains, significantly altering the landscape.
