Ecologists raise alarms over pink water lily spread in Malarikkal

UPDATE - follow-up to Pretty in pink, but Malarikkal's lilies worry ecologists: Unchecked growth of pink water lilies in Malarikkal poses serious threats to local ecosystems, according to a recent study.

Study Findings

A two-year study conducted for the Kerala State Biodiversity Board reveals that the water lilies have shown unprecedented and uncontrolled growth since appearing after the 2018 floods. Ecologists warn that this rapid spread impacts native aquatic plants, blocks water flow, and stops sunlight from reaching deeper water.

Economic Impact

At the same time, the seasonal bloom running from July onwards has turned Malarikkal into a major tourism hotspot. This floral economy brings extra income to local residents, boat operators, and farmers during the three-month period.

Context

Environmental studies often highlight the trade-offs between boosting local tourism economies and protecting native species from invasive or fast-spreading plants. When non-native or sudden plant growth takes over water bodies, it can disrupt natural habitats while simultaneously offering temporary financial benefits to local communities.
