It's wonderful that you professionals are so knowledgeable about introduced species. However, the question I raised is: what about the ones that have been pushed out? I will consult a geographer, to ascertain the changes in terrain--wetlands filled in, streams driven underground, etc. that would give me aquatic plants and animals no longer prevelant. What about any species that are now very rare in what remains of metro's woodland and meadowland? Or do all of these still thrive in unpopulated areas of the province? I would be thrilled to get a few flowering plants, small mammals, and insects (especially butterflies)--so photogenic for an art project. If I am able to carry out my plan, I will certainly give credit to all who have helped. Jane ----- Original Message ----- From: "Paul S.
