Topic: Conservation, environmental pollution and degradation, environmental impact assessment
Q6. “Climate change is increasingly blurring the distinction between invasive species and climate-resilient species”. Evaluate the long-term ecological consequences of this shift for biodiversity conservation. (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question
Climate change is restructuring ecosystems and complicating conventional invasion biology, making it directly relevant for biodiversity conservation.Key Demand of the question
The question requires explaining how climate change is blurring the boundary between invasive and climate-resilient species. It further demands an evaluation of the long-term ecological consequences of this shift for biodiversity conservation.Structure of the Answer:
Introduction
Briefly highlight climate-induced range shifts and the changing ecological baseline that challenges static native–alien classifications.Body
- Blurring of ecological categories: Explain how warming, extreme events and degraded habitats enable certain non-native species to function as climate-resilient survivors, complicating traditional invasive labels.
- Ecological consequences for biodiversity: Evaluate how this shift may lead to homogenisation, altered ecosystem functions and governance dilemmas in conservation policy.
Conclusion
Conclude with the need for adaptive, science-based biodiversity management frameworks suited to dynamic climate realities.
