Natalie Stafl, executive director of the Columbia Shuswap Invasive Species Society, talks with MP David Wilks on Wednesday, February 11, about the aquatic invasive species such as zebra mussels and other alien lifeforms that could have a major impact in the Columbia River basin if they get a foot hold here. CSISS and allied groups in the region want Ottawa to contribute funding and concrete actions to stem the sloe invasion that could cost the economy tens of millions of dollars a year. David F.
