Take
a Look at the Data from Mexico
This bar graph shows the data scientists have collected since
1994. It shows the estimated size of the monarch population in
Mexico every year. The area covered in monarchs is measured in
"hectares." One hectare is 2.47 acres, about the size
of two and a half football fields. Can you find this year's data?
How does it compare to other years? Why do you think it's important
to collect and study population data every year?
