I'm going to answer the second part first - as its easy: in 2002, the Emerald Ash Borer was identified in the Windsor area. (Living in the Great Lakes area makes you very aware of the problem of invasive species).
The first part of the question bothers me. By using the word, 'wild' I'm assuming the question is about animal migration - but how well versed are we in animal migrations from 500 years ago?
Ah, it appears that Kevin Kelly has had second thoughts on this question as well...
If I could re-write this question, I would ask about now extinct life that once resided where you lived -- if only to write about the now extinct giant beaver that once grew to 2/3 the size of a black bear.
