Hand Pulling Starry Stonewort Helps Protect Native Plants

Wed, 16 Feb 2022 22:03:03 +0000

Heidi Bunk, a water resources management specialist with the Wisconsin Department of Natural Resources, said while the long-term effectiveness of hand pulling the invasive species starry stonewort is still being evaluated, it can be advantageous because it allows for the removal of starry stonewort without harming native species in the way chemical treatments might.

She said lakes that are over-managed with chemical treatments, which can kill native plant species, can actually increase the spread of some non-native species. She said while the treatment may temporarily reduce a starry stonewort population, it also opens the door to future spreading by potentially killing native plants that would otherwise compete with the invasive species.

Manual Water Hyacinth Removal Raises Concerns Over Spread

Nyamitanga Division Chairperson Moses Karanzi Kajubi says the move to manually remove the water weed should be supported instead of being criticized. He says that they intend to do the cleaning of the river at least once a month, by pulling the water weed out of the water and cut it into pieces so that it dries up.

Bright Muhumuza, an environment activist says that the manual removal of the weed spreads it further. He adds that there is special equipment that is used to remove the weed instead of the irresponsible removal using rudimentary means.

Kaberebere Town Council Chairperson Patrick Kajuba says that the initiative may be having good intentions which may, however, be spoilt by the mode of implementation.
