The Christmas Tree Reef

I just read in William Ashworth's book Great Lakes Journey about a wonderful idea they had in Collingwood, Ontario, Canada. They (i.e. smart Canadians) collected discarded Christmas trees, stuck the trunks in cement, then sank the whole thing into Lake Ontario. Voila--a new reef for fish. The next year fish populations rose something like 1000%.
