If your task force establishes an overarching management policy or a management plan for salmon, then within it there might be segments that particular people could address more adequately than others. For example, Dr. Cunjak is a freshwater biologist specialist. Maybe part of it requires that. There may be somebody else who could deal better with the estuaries. There may be somebody else who'd be better at the marine science.
So you're giving everybody what they do best in order to contribute to an overall better result in the end.
