Alarm Bells Ringing: Decline of Dragonflies in India's Western Ghats

Introduction

In the heart of India's Western Ghats, renowned for its staggering biodiversity, a recent study has unveiled alarming findings concerning its fragile ecosystem. Specifically, dragonflies and damselflies—critical indicators of environmental health—are in distress.

Key Findings of the Study

Conducted over two years (2021-2023), this groundbreaking research identified 143 species of dragonflies and damselflies in the Western Ghats, with at least 40 endemic to the region. Yet, troublingly, the researchers discovered a decline of approximately 35% in species richness—with 79 species, previously recorded, no longer found.

“Dragonflies and damselflies are good indicators of the health of a region. Consequently, when their numbers drop, it could signal the potential degradation of an ecosystem,”

The Importance of Dragonflies and Damselflies

• Ecological Indicators: Their presence or absence can signal broader environmental trends that could affect other species.
• Endemic Species: The Western Ghats are a treasure trove of unique species, with many that provide critical ecological functions through pollination and habitat maintenance.

Concerns Over Decline

Koparde notes that while some of the missing species might be rare or only active in specific seasons, the possibility of extinction looms large. Urbanization, agricultural expansion, and infrastructure developments pose serious threats to this biodiversity haven.

Documenting Biodiversity in the Western Ghats

Research efforts have been strenuous, involving hikes through difficult terrain, such as mossy riverbanks and mangrove swamps, showcasing the rigorous dedication of researchers.

Global Context

The decline in dragonfly populations parallels alarming global trends, often referred to as “ecological armageddon.” Multiple studies indicate sharp drops in insect populations worldwide, raising concerns about long-term ecological balance.

The Role of Conservation Efforts

The urgent need to monitor populations and protect habitats is underscored by the IUCN's 2025 report, which categorizes the Western Ghats as being under significant threat. Conservation efforts are paramount, and raising public awareness is a crucial element for change.

Conclusion

The findings from the Western Ghats serve as a wake-up call. As ecosystems face escalating threats, every effort to document and protect our natural heritage can lead to greater environmental stewardship. It is incumbent upon us to heed these alarm bells before they fade into silence.

Follow-up Actions

1. Engage with local conservation groups to understand how you can contribute.
2. Stay informed on policies impacting biodiversity in your area.
3. Support sustainable practices that protect critical habitats.
