Invasive Plant Species Act as Crucial Nectar Sources for Assam Butterflies, Study Finds
A study conducted in Raimona National Park, Assam, revealed that certain invasive exotic plant species, often considered undesirable, serve as major nectar sources for a large number of butterfly species. Researchers documented 220 butterfly species and identified 41 nectar plants, including Lantana camara, Chromolaena odorata, and Ziziphus mauritiana, which are aggressive invasive species. These plants provide abundant nectar, especially when native wildflowers are scarce, and their prolonged flowering periods help sustain butterfly populations. The study suggests maintaining small, managed patches of these invasive plants in protected landscapes to ensure continuous nectar supply for butterflies.
Key Points
- Invasive plant species like Lantana camara and Chromolaena odorata are crucial nectar sources for butterflies in Raimona National Park, Assam.
- These "unwanted" plants provide essential nutrition, especially when native wildflowers are scarce.
- Their prolonged flowering and high nectar availability help sustain butterfly populations.
- The study recommends managing small patches of these invasive species in protected areas to support butterfly diversity.
