How Many Football Fields Would the Monarchs Cover?

Example: Using the population estimate of 1.19 hectares in winter 2012/2013, here is our calculation:

  • 1 football field is roughly 1 acre. (The exact measurements of football fields vary.)
  • 1 hectare = 2.47 acres
  • 2.47 football fields in 1 hectare
  • 1.19 hectares of monarchs
  • 1.19 X 2.47 = 2.93 football fields of monarch trees this year.

Just think: Monarchs flew to Mexico from across eastern North America and occupied an area smaller than 3 football fields!
