What does a high diversity index typically indicate?

A high diversity index typically indicates a greater variety and relative abundance of species within an ecosystem. This occurs when there are many different species present and they are represented in relatively equal measures, suggesting a rich and balanced ecosystem. High biodiversity is crucial as it often leads to increased ecosystem resilience, allowing for better adaptation to environmental changes and disturbances. Diverse ecosystems are more likely to maintain ecological balance and provide a range of services such as pollination, nutrient cycling, and habitat stability.

In comparison, a low diversity index would imply fewer species, which could lead to increased vulnerability of the ecosystem. High levels of only one or a few species could suggest an imbalance, possibly resulting from environmental stress or human impact.
