According to the Fisheries and Oceans marine mammal group on Vancouver Island, who are the keepers of this kind of information and have been doing wonderful studies on pinnipeds over the years, the harbour seal populations have rebounded now to something like historic levels throughout the province. After a long series of culls, harbour seal populations have levelled off, and in fact have come down slightly, so the recent news about exploding seal populations is simply wrong. That explosion has taken place; it's over now. Sea lion populations are still increasing at a slow rate.
