Every year thousands of students across North America follow the migration of the Monarch butterfly as spring moves north. But this year, there may be a decline in the number making the trip. Satellite photos found by biologist Lincoln Brower at: <http://www.learner.org/jnorth/monarch/MonarchImages.html> reveal there’s been illegal clear-cutting in the forested areas of Mexico where many butterflies spent the winter last year. The problem was covered on the Public Radio International program, “The World.” Visit the “Journey North” site to find out more about the annual migrations of a range of critters, and watch how school classes report local sightings at: <http://www.learner.org/jnorth/>
