Re: Monarch butterflies, are they more uncommon?


I've heard other people express the same feeling.  

If I remember correctly, the small forest tract in Mexico where they
overwinter is being logged illegally.  It's officially protected, but
they're having a hard time keeping the locals from cutting trees and
grazing etc.  It's also being "loved to death" by tourists.  I'm sure this
could have a severe impact on their numbers.
