Fishing Licensing Exams?

This is my first post, and thank-you, MichaelAngelo, for the warm welcome.
I'm writing about Grenadier Pond in High Park, Toronto.
Birds and turtles get killed by monofilament. About 10 signs went up around Grenadier Pond in June to warn anglers of the danger, asking them to make sure to pick up their line and other gear, and since then there have been more incidents than ever. Volunteers pick up monofilament every day, never visit the pond without scissors and tweezers to free entangled wildlife, and are on a first-name basis with Toronto Wildlife. Toronto Wildlife spends a couple of weeks rescuing some poor animal, performing specialized surgery, and then have to release it right back to Grenadier Pond. A pond that is an important migratory bird stopover. The MNR has actually made a few visits this year but, as many of you have noted, enforcement is woefully inadequate.
It would be really nice if the angling community were part of the solution. (This recommendation actually dates from 1995.) Obviously, most people are not bad apples. But Grenadier Pond is very small and very popular and only needs a few bad apples to make the place unsafe for wildlife.
So what would you do, if Grenadier Pond were yours?
