Mexico’s Monarch Butterflies Are in Grave Danger. Scientists Are Moving an Entire Forest to Save Them.

Their habitat could soon be eradicated by climate change.

Tree by tree, Mexican scientists are planting the first stages of a new forest in the mountains of the country’s central Michoacan state. They’re taking saplings from oyamel fir trees further down the mountain and creating a new home for them higher up. Three and a half years ago, the first batch of transplanted trees were each seven inches tall. Now, thousands of saplings have grown, some up to four feet tall.

These trees are home to millions of eastern monarch butterflies who migrate there every winter, and in moving the forest, scientists are hoping they’ll be able to save the species and their habitat. Worldwide, the monarchs’ habitats have become increasingly endangered by herbicides, logging, and the storms and warming temperatures associated with climate change. The new forest, which researchers hope to replicate on nearby mountaintops, would replace lower-altitude forests that are getting too warm for butterfly hibernation. The trees create a cooler microclimate for the butterflies and protect them from chilly winter rains. The experiment is a form of “assisted migration” that is also happening with other plant and animal species in places such as Canada and in parts of the United States.

“It’s an idea that may sound radical,” forest geneticist Cuauhtemoc Saenz-Romero tells the Los Angeles Times. “But by the end of the century it may be absolutely needed.”

Mexican researchers and farmers are doing the transplanting, including Francisco Ramirez Cruz. A local 75-year-old farmer, he is helping to grow the saplings in a greenhouse and transplant them up the mountain. He says preserving the butterflies’ habitat will also help protect the tourism and timber on which many of his neighbors depend.

“In the early days, we didn’t know where they came from,” he says of the fluttering wonders. “But we have always been so happy to see them.”

Here are some other Recharge stories to get you through the week.

  • Short story with your commute? Thanks to new vending machines at a British rail station, commuters have been offered a mental treat: A choice between one-, three-, and five-minute short stories, printed out for the trip. Riders seem to enjoy the three free vending machines, which were installed earlier this month at Canary Wharf in London, and the effort helps people get off their phones—for a bit. “Every single day,” says commuter Paresh Raichura, “I’m on the lookout for something new to read.” (The Guardian)
  • An inspiring advance. Computer scientist Katie Bouman became an internet star last week when a photo of her in front of the first image of a black hole went viral. Trolls quickly descended, denigrating her effort and wrongly crediting a male colleague with the bulk of the discovery. MIT clarified that her contributions were significant to the project, inspiring the team’s methods to build the final image. Bouman’s work was part of a 200-member team effort, and in a Facebook post she emphasized: “No one algorithm or person made this image.” What can’t be denied is the infectious joy that Bouman brought to the moment, as seen in this video from Nature.

  • The world rallies for Notre Dame. After the devastating fire in Paris this week, global leaders sang praises and offered prayers. Donors have pledged hundreds of millions of dollars to help rebuild. And when the fire topped its iconic spire and destroyed much of its roof, students and others took to the streets Monday night to serenade the famous cathedral, whose altar and famous bell tower still stood. “Honestly, it’s more moving than I could describe,” tweeted one visitor, who shared a video of the singing procession. France’s US ambassador thanked Americans for their support and added: “All together, we’ll rebuild #NotreDame for the coming millennium.” (CNN)

WE'LL BE BLUNT

It is astonishingly hard keeping a newsroom afloat these days, and we need to raise $253,000 in online donations quickly, by October 7.

The short of it: Last year, we had to cut $1 million from our budget so we could have any chance of breaking even by the time our fiscal year ended in June. And despite a huge rally from so many of you leading up to the deadline, we still came up a bit short on the whole. We can’t let that happen again. We have no wiggle room to begin with, and now we have a hole to dig out of.

Readers also told us to just give it to you straight when we need to ask for your support, and seeing how matter-of-factly explaining our inner workings, our challenges and finances, can bring more of you in has been a real silver lining. So our online membership lead, Brian, lays it all out for you in his personal, insider account (that literally puts his skin in the game!) of how urgent things are right now.

The upshot: Being able to rally $253,000 in donations over these next few weeks is vitally important simply because it is the number that keeps us right on track, helping make sure we don't end up with a bigger gap than can be filled again, helping us avoid any significant (and knowable) cash-flow crunches for now. We used to be more nonchalant about coming up short this time of year, thinking we can make it by the time June rolls around. Not anymore.

Because the in-depth journalism on underreported beats and unique perspectives on the daily news you turn to Mother Jones for is only possible because readers fund us. Corporations and powerful people with deep pockets will never sustain the type of journalism we exist to do. The only investors who won’t let independent, investigative journalism down are the people who actually care about its future—you.

And we need readers to show up for us big time—again.

Getting just 10 percent of the people who care enough about our work to be reading this blurb to part with a few bucks would be utterly transformative for us, and that's very much what we need to keep charging hard in this financially uncertain, high-stakes year.

If you can right now, please support the journalism you get from Mother Jones with a donation at whatever amount works for you. And please do it now, before you move on to whatever you're about to do next and think maybe you'll get to it later, because every gift matters and we really need to see a strong response if we're going to raise the $253,000 we need in less than three weeks.
