Dorekere with its rich flora & fauna, model for lake rejuvenation

Bengaluru, NT Bureau: Dorekere Lake, spanning 2 8 acres in Uttarahalli, is a testament to Bengaluru’s rich biodiversity.

This welldeveloped lake not only supports a vibrant ecosystem but also contributes to groundwater replenishment and provides fresh air to local residents. According to a recent report by the ActionAid Association, Dorekere Lake is home to an impressive array of flora and fauna.

The lake hosts 73 species of herbs and shrubs, 57 tree species including the Golden Shower Tree, Terminalia Arjuna, and Ficus Arnottiana, and 768 individual trees.

It is a haven for 74 bird species, such as the Spot-billed Pelican, Painted Stork, and Blackheaded Ibis, 11 migratory species and three nearthreatened species as per IUCN 3.0.

Additionally, 26 butterfly species, like the Common Banded Peacock and Lascar, have been observed. Discussing the significance of biodiversity in lakes, bird watcher J.N. Prasad emphasised, “The quality of biodiversity in an area can be gauged by the bird species present.”

Senior environmental journalist Nagesh Hegde added, “Rejunuvating a lake involves more than just BBMP efforts; it requires active participation from youth and residents to ensure water quality supports both human needs and environmental health.”

Annapurna Kamath, Director of Jalposhan, stated, “Development should prioritise biodiversity over human interests. While lakes serve people, preserving biodiversity is crucial.”

She suggested that eco-sensitive lake rejuvenation is possible only when local communities take ownership. Author and Bird Podcast host Shobha Narayan noted, “We rely on biodiversity, not the other way around.”

Indrani K.M., Executive Engineer at BBMPLakes, reinforced that lake development should focus on enhancing biodiversity rather than solely catering to human needs.

The survey highlights Dorekere Lake as a crucial habitat with rich biodiversity. Recommendations include developing wetlands as buffer zones, planting native grass and balancing native and non-native species. Measures to reduce monocultures, protect native flora, manage wildlife threats, and maintain lake fences are also proposed.
