Monarchs Thrive as Mexico Guards Butterfly Habitat
In Michoacan’s highlands near Mexico City the monarch reserve now sits quieter as chain saws are silenced and fir trees stand protected. Federal agents guard forests while peasants find legal jobs, preserving critical oyamel fir habitat that supports a yearly mass migration from Canada and the northern United States. The reserve reopened to tourists as the monarch season runs to early April, amid theories on their navigation and reliance on the fir trees for warmth.
