Before we cover the good news today, let’s not forget the innocent people who lost their lives at the hands of fanatic Islamists on September 11, 2001- twenty-five years ago. I planned not to run a good news feature on this tragic anniversary, but I feel we should keep focusing on the good news when there is so much bad news in this world.
Today’s good news story comes from Diario AS and was sent to me by Noelle Granger, reporter at large. Thanks, Noelle
Mexico protected more than 1 million monarch butterflies in 1980. Decades later, they’ve created a one-of-a-kind ecosystem
The monarch butterfly’s migration is one of nature’s greatest journeys. Every fall, millions of monarchs travel more than 2,500 miles from southern Canada and the northern United States to spend the winter in the cool oyamel fir forests of central Mexico.
But behind this extraordinary spectacle lies a story of government protection, scientific discovery, and ecological recovery that permanently changed conservation efforts across North America.
After the first federal conservation decrees were issued in 1980 to protect the butterflies’ overwintering grounds, authorities safeguarded forests that host well over one million monarchs. Those protections laid the foundation for a protected ecosystem that now covers more than 139,000 acres.
The 1980 decree that changed everything
For decades, the exact location of the monarch butterflies’ winter colonies in Mexico’s mountains remained known only to local communities. That changed in the mid-1970s, when international researchers working alongside Mexican scientists mapped key overwintering sites in the Sierra Chincua and Cerro Pelón mountains.
In 1980, Mexico’s federal government issued its first presidential conservation decrees to formally protect the forests where enormous monarch colonies gathered each winter. Individual sites often contained well over one million butterflies.
The move helped curb uncontrolled logging in some of the most important habitats and marked the beginning of what would eventually become the Monarch Butterfly Biosphere Reserve. Today, the protected area stretches across municipalities including Zitácuaro, Ocampo and Angangueo in the state of Michoacán, as well as Temascaltepec and San José del Rincón in the State of Mexico.
A UNESCO-recognized sanctuary
Covering 139,000 acres (56,259 hectares), the Monarch Butterfly Biosphere Reserve sits about 60 miles northwest of Mexico City in a mountainous region filled with dense forests. Its varying elevations create a range of microclimates that support numerous native plants and animals found nowhere else.
Every fall, millions — and in some years perhaps as many as a billion — monarch butterflies from across North America gather in small patches of forest within the reserve. Their bright orange wings blanket the trees so completely that entire hillsides appear to change color.
The sheer weight of so many butterflies can even bend tree branches.
When spring arrives, the monarchs begin their remarkable return journey north. Over the next eight months, the migration unfolds across four successive generations as the butterflies spread through the United States and into eastern Canada.
Despite decades of scientific research, one mystery remains unsolved: exactly how each new generation finds its way back to the same forests in central Mexico where its ancestors spent the winter.
The good news is that the Mexican government’s protection has ensured the Monarch’s survival. Today’s JohnKu talks about government action. I hope you have a super weekend.

Government does well,
When it regulates for good . . .
Saving the monarchs.
