Kudzu, or Japanese arrowroot, is an invasive vine that climbs and encases anything it encounters, including native vegetation like these trees in Mississippi. It’s sometimes called ‘the vine that ate the South.’

Scientists want to understand behaviour of invasive weeds

Why are certain plants able to enter a new ecosystem and run riot?

By Manitoba Co-operator Staff February 6, 2018

Is it possible to predict which non-native plant species will become invasive weeds and when? According to research featured in the journal Invasive Plant Science and Management, the answer is “hopefully yes.” Researchers say invasive species generally follow a three-phase development curve — from lag to expansion to plateau. The length and rapidity of the

The introduced invasive species spotted knapweed is easily identified once the plant produces its distinctive bright-pink flowers. But at this stage it is already well past the stage where controlling its spread is easy or feasible, warns the Invasive Species Council of Manitoba.

Tracking the elusive but destructive wild boar

The highly reclusive wild boar may be responsible for much more  crop damage than previously thought

By Shannon VanRaes July 16, 2015

Ruth Kost has never seen a wild boar before but she’s hoping that will change after a summer spent tracking the elusive beast. “They don’t like to show themselves,” said the University of Saskatchewan master’s student. “They are kind of reclusive, they avoid people… and they’re very aware of hunting pressures.” But just because you

Invasive Species Lie In Wait, Strike After Decades

By Alister Doyle January 6, 2011

Animals and plants introduced from foreign habitats may not reveal themselves to be harmful “invasive” species for decades, according to a recently published European study. Species that are moved away from their natural predators back home can displace native species in their new habitats, and scientists say the problem already costs Europe 12 billion euros
