The Warm Winter of 2006
This is the 13th year we have tracked monarch migration, and never have so many monarchs been so far north so early in the spring! Take a look! The red triangles on the migration map show where people saw monarchs this winter in January or February. Do you see some surprises? Keep these sightings in mind as you track the migration this spring. Look at the temperature maps to see how this winters temperatures have been different.
What statements can you make about weather and monarch survival in winter, based on these maps?
