A systematic search of boat ramps along Southland lakes in May had found them free from lagarosiphon again this year, a pleasing result for the Department of Conservation.   READ MORE

"There were people who worked here for years that wouldn't swim here because it was too weedy," Shaw said, as he stood on the dock near Vikingsholm Wednesday. "The weeds would wash up on the beach." Today, much of the iconic bay's shoreline is sparkling clear and free of Eurasian milfoil, the aquatic invasive species that mucked up the area.   READ MORE

Efforts to eradicate a fast-spreading aquatic weed that threatened to choke the life out of Lake Pinehurst have been so successful that some may not think there is still a threat.

Water chestnuts were almost eradicated in the 1990s, but when the Mass.

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
