McQuarrie Director of Education DISPLAY AA TOWNSHIP OF TERRACE BAY fe Alien species in the Great Lakes Continued from page 15 is expected to be spent by ship- ping, pleasure boating and fish- ing interests for cleanup and controls. Recreational boaters, anglers and others using the lakes can help in controlling the spread of the mussel by washing all boats or equipment used in one of the Great Lakes before entering inland water- ways. The mussel filters water as it feeds, consuming valuable phy- toplankton -- alga and other small aquatic plants -- that are the normal food sources for the ecosystem's larger species. Thus, the invader's eating habits could short circuit a food chain that has evolved over thousands of years, especially since only one fish species (freshwater drum fish) and the Hydraulic Hammers available to fit any size of machine.

With the alterations to the Great Lakes environment from these exotic species becoming more obvious, the GLFC and the International Joint Commis- sion, a treaty organization between Canada the the United States focusing on boundary water issues, issued a strongly worded report last fall urging both countries to immediate action to prevent additional exotic species from entering the Great Lakes ecosystem. The Commissions recom- mended that all oceangoing ships be required to exchange ballast waters in mid-ocean before entering the Great Lakes or their connected waters. Such an exchange lessens the chance of entry and survival by exotic species, since there are mid-ocean areas that are virtu- ally devoid of life and species from salt water are less likely to survive in fresh water and vice versa. In cases where this is not an option, all ballast water must be treated so exotic species are either removed or destroyed before being discharged into the lakes. If a ship does not comply with these provisions, it should be prevented from entering the waterways to the Great Lakes. The Commis- sions also recommended that research programs be devel- oped to further define options for virtually eliminating the introduction of exotic species into the ecosystem. Canada initiated voluntary ballast water guidelines similar to the Commissions' recom- mendation in May 1989. Four out of five ships have complied with these voluntary provi- sions, but that still means that at least 100 ships are discharg- ing 100 million gallons of water and organisms into the system each year. In the U.S., Congress passed the Nonindigenous Aquatic Nuisance Prevention and Con- trol Act last November, which provides $150 million over the next five years for programs on aquatic species in the Great Lakes. The act mandates bal- last water exchange begin in 1993 but does not specifically address waters connected to the Great Lakes. Voluntary com- pliance similar to the Canadian . guidelines is required until then. The act also specifically earmarks $13 million for zebra mussel research and control. Both Commissions believe controlling the zebra mussel population alone will cost "hundreds of millions of dol- lars" each year for the next decade. Preventing new species from entering the Great Lakes will cost less in the long run, they believe, than trying to control the mussel, lamprey and other nuisance species that drastically affect the Great Lakes ecosystem's fragile food chain. One thing is certain: until major routes of entry for exotic species are eliminated, more invasions are inevitable. Eradication of aliens, once arrived, will be impossible. Continued from page 5 Despite the differences in approach evident in NAN, Toronto, Ottawa, and the non- native interest groups, I remain _ optimistic about all this. I firmly believe that by the end of this century, there will be another level of government in northern Ontario - called the Nishnawbe-Aski Nation - one complete with its own system of laws and institutions. Since the negotiations with NAN are further advanced than with other regional aboriginal groups, the NAN discussions will no doubt set the prece- dents that others can follow. These new regional govern- ments will have disputes, both internal and external, just like the governments we have now. But if everyone involved in these negotiations sticks to the principles they've outlined, we should see governments unlike any other - ones based on new understandings of how to live together, as First Nations, and as Canadians.
