Wayanad, Kerala, September 2025 – In a pioneering conservation move, Kerala has conducted India’s first science-based, community-driven eradication program against Senna spectabilis, an invasive alien plant species threatening biodiversity in the Western Ghats.

What is Senna spectabilis?

Origin: Native to tropical regions of the Americas.
Type: Medium-sized tree (7–18 m) with a dense spreading crown.
Appearance: Resembles Cassia fistula (Kerala’s state flower, Kanikkonna).
Impact:
- Forms dense, sterile thickets that prevent native vegetation from growing.
- Alters soil chemistry, disrupting natural regeneration cycles.
- Reduces food sources for herbivores, impacting wildlife populations.

Why It Matters

Senna spectabilis has spread rapidly across Wayanad Wildlife Sanctuary and adjoining forest areas. Its invasive nature threatens the survival of endemic flora and fauna, making urgent intervention necessary.

Community-Driven Approach

Local Participation: Forest-dependent communities worked alongside scientists and forest officials.
Science-Based Methods: Mechanical removal, root extraction, and soil restoration techniques were employed.
Goal: Restore ecological balance while empowering local communities in biodiversity conservation.

What Are Invasive Species?

Invasive species are non-native plants or animals introduced (intentionally or accidentally) to new regions, where they spread uncontrollably and cause ecological, economic, or social harm. Globally, they are among the top five drivers of biodiversity loss.

Significance of the Initiative

Marks the first structured eradication effort in India targeting an invasive species with community participation.
Sets a model for other states to combat invasive alien species threatening forests, farmlands, and wetlands.
Supports India’s commitments under the Convention on Biological Diversity (CBD) to protect ecosystems from invasive species.
