Exotic weed spreads its tentacles in Waipa waterways

A blackmarket trade in a Brazilian aquatic weed is threatening to choke waterways in the Waipa District that could flood land and create a hazard where people and livestock could drown. Salvinia (kariba weed) was introduced to New Zealand nearly a century ago for fishponds and is now found in Northland, Auckland, Waikato and Bay of Plenty. A Waipa District Council worker discovered a small amount of the invasive plant in a stormwater pond near Te Awamutu last month but failed to recognise the species and when he returned six weeks later, he found the pond choked by the plant. “In six weeks it had gone from pretty much nothing to the entire 50 metres by 20 metres pond,” Waikato Regional Council biosecurity officer Darion Embling said. READ MORE
