So the numbers are out on the eastern Monarch population in Mexico for the winter of 2015-2016, and the news is good. The Monarchs roosting in pine forests occupied a total of 4.01 hectares (a little under 10 acres) this year, more than three times last year’s 1.13 hectares (less than 3 acres). The population nadir occurred in 2013-2014, when Monarchs covered just 0.67 hectares, about 1.5 acres.
