New Centre Will Focus on Invasive Species
Sault Ste. Marie, Ontario, will soon be the home of a new
Invasive Species Centre focusing on protecting the Canadian and other
waters and forests from invasions of exotic species.
The new multimillion-dollar centre will have cooperative
funding from the Ontario provincial and Canadian national governments.
It will be built on the site of the Great Lakes Forestry Centre, which
is one of six such centres in Canada. The Invasive Species Centre has a
commitment of about $24 million (Can.) from the national and provincial
governments.
According to Minnesota Sea Grant, 87 non-native species have
been identified in Lake Superior since 1883. Of those 87 exotic
species, 21 were introduced intentionally (like some salmon stocked in
the lake), 47 were introduced unintentionally and the exact
introduction is unknown for 19. The species are both plant and animal
or even pathogens (bacteria).
