How Many Monarchs? Analyzing Data from Journey North


How many monarchs are in the Mexican colonies? Here is a bar graph taken from the Journey North website. Listed are data taken from 1994-95 through 2008-09. Answer the following questions:

    1. In what year were the most monarchs recorded? What is the reason you think these numbers are so high?
    2. In what year were the least monarchs recorded? What do you think could have happened to make these numbers so low?
    3. Scientists look for trends. (A trend is a general direction in which something is moving.) What trends do you see in the data?

More questions will be coming, so make sure to keep visiting our blog!

Journey North Tracks Monarch Migration

There is a fabulous website out there called ‘Journey North’. The website URL is: www.learner.org I have visited this site for many years and have used it for:

  • learning about robins and their migration
  • spring peeper frogs and their spring arrival and
  • of course, for monarch butterflies!

The website is updated on a weekly basis and this week’s site is FANTASTIC! There is information on the colonies, how many monarchs are in the colonies this year and so much more. Here is an amazing photo, taken by Dr. Lincoln Brower. Do you notice anything unusual about this photograph?? PLEASE POST AND TELL ME WHAT YOU THINK!
