Introduced and Invasive Species

Introduced species Also known as: nonnative, nonindigenous, alien, exotic Introductions can occur naturally, but now are driven primarily by human factors (esp. trade, travel)

From introduced to invasive Vast majority of introductions do not result in establishment of invasives However, repeated introductions can lead to invasions (European starlings were introduced 4 times) Propagule pressure

Ecological context Not just about species attributes Disturbance can reduce competition from native plans Nutrient availability Community diversity Enemy release hypothesis

Leafy Spurge

How do we reduce or manage species introductions?

Canada’s approach to Leafy Spurge Biological control: Sheep, Beetles Elbow Pasture, SK: 1200 sheep Reduced spurge density from stems/m 2 to stems/m 2 in a few years Cattle stocking 36% higher Beetles: down to 10% afficher.do?id= &lang=eng

Pragmatic approaches 1) Prevention

Pragmatic approaches 2) Eradication: shoot first, ask questions later video

Pragmatic approaches 3) Management -Chemical or biological control -Habitat modification -Manual removal -Problem: costs $$$ year after year

What about human values?
