Wonder if the frothing of Bellandur and Varthur water bodies started after the depletion of Water Hyacinth in the lakes? Outright removal or serious depletion of successful and ecologically dominant species would drastically alter energy flows and bioremediation in an ecosystem, and replacements would be very hard to come by in the energy pathways of that system. It would indeed be very imprudent to remove or disrupt successful plants like Ipomoea carnea or Eichhornia crassipes in our tampered waterscapes!
