First there were zebra mussels, spiny water fleas, purple loosestrife and the common reed.
Now there is another invasive species to worry about in Ontario.
Its called Kudzu vine, and it has been discovered along the shores of Lake Erie, near Leamington and is a serious threat as it moves quickly, stretching across the countryside and engulfing trees, fences and homes.
Rachel Gagnon is with the Ontario Invasive Plant Council and tells Bayshore Broadcasting News the plant is very aggressive plant, growing as much as a foot per day and it reaches up hydro poles and across transmission wires, eventually collapsing them under its weight.
She says the vine overtakes and suffocates trees and crops and pollutes watersheds and basically just takes over.
Gagnon says its caused all sorts of damage in the US and is known as the vine that ate the south.
She says the plant costs the US agriculture industry more than 500 million dollars a year to try and contain and eliminate it.
She says controlling and eliminating this vine is critical to maintaining native plants and wild life habitat.
Gagnon says if Kudzu becomes established it will cause untold ecological and economic damage.
She says there are several ways to try and get rid of the vine including the use of chemicals, digging out the roots or even using pigs which like to dig up and eat the roots.
Gagnon says so far the vice has been limited to a 100 meter stretch of land near Leamingrton and hopefully they can eliminate before it begins to spread across the rest of the province.
