Invasive species are plants, animals or tiny organisms that don’t belong in an area causing harm to the environment, economy and native wildlife by spreading quickly out of control.
Key factors contributing to Invasive Species rise –
- Disturbed soil and vegetation disrupt ecosystem balance, creating opportunities for invasive species to establish.
- Altered nutrient cycles due to human activities favor invasive species growth, outcompeting native vegetation rapidly.
- Climate and microclimate changes alter ecosystem conditions, enabling invasive species to thrive and outcompete natives.
- Human activities like trade, travel, agriculture and landscaping intentionally/unintentionally introduce invasive species, spreading rapidly.
Habitat loss and the rise of invasive species are interconnected and synergistic processes that exacerbate the degradation of altered ecosystems i.e.
- Habitat loss weakens native species competitive advantages by facilitating invasive species establishment, displacement and extinction, disrupting predator prey relationships and ecosystem resilience.
- Habitat loss reduces biodiversity, weakening ecosystem resilience, making native species more vulnerable to invasive species colonization, establishment and dominance, exacerbating ecological disruption.
- Habitat fragmentation creates isolated patches by facilitating invasive species spread via corridors while reduced connectivity hinders native species migration, exacerbating vulnerability to invasion.
Governments implement initiatives to mitigate habitat loss and invasive species by regulating trade, enforcing biosecurity, restoring habitats, monitoring ecosystems and promoting sustainable land use practices, supporting research and public awareness campaigns.

Model Answer Favorable Conditions for Coral Reef Formation Coral reefs thrive under specific conditions, including: Water Temperature: Corals require warm waters, with temperatures between 20°C and 28°C. This is why reefs are mostly found in tropical and subtropical regions (Source: Coral Reef EcoloRead more

Coral reefs thrive under specific conditions, including:
Factors Contributing to Coral Reef Decline
Several factors are leading to the decline of coral reefs:
These factors contribute to the loss of approximately 14% of the world’s coral since 2009 (Source: Status of Coral Reefs of the World: 2020).
