Weeds causing waterway havoc
Two banned and highly destructive weeds – water hyacinth and salvinia – need to be eradicated and Auckland Council wants your help.
Council and the Ministry for Primary Industries want residents to report any fresh sightings of the weeds to 0800 80 99 66.
Contractors will visit and remove the weeds for free if they find them.
Salvinia is a small, freefloating aquatic fern with branched, horizontal stems that lie just below the water surface. The upper surface of the leaf is covered with distinct white hairs.
The weed has the potential to cause huge damage to waterways, native aquatic plants and fish.
They can clog waterways, making almost all water activities impossible and increasing the danger of drowning to humans and livestock.
Both weeds are present in the Auckland region and are known for growing rapidly to form large dense floating mats on ponds, drains, lakes and still waters in swamps.
Kills others: Water hyacinth has a distinctive bladder-like swollen leaf and thick masses of feathery dark roots that can reach 2.5m in length.
