Y'all I have to tell you about the tortoises!!!!!!
Okay so I'm doing background information comes first bc this is the order I learned it in and it's such a conservation rollercoaster
So the Galapagos Islands off the coast of Ecuador are home to some of the largest tortoises in the world. Huge. Beautiful. Iconic.
What I didn't realize is that, just like Darwin's finches all adapted unique beaks for conditions on the different Galapagos Islands, different islands have their own unique variety of giant tortoise!
But bad news for tortoises, in the 1700s-1800s whalers and other sailing ships would stop in and grab as many tortoises as they could carry as portable snacks bc the tortoises can live a few months without eating, so they make good fresh meat in a long voyage??? And it turns out if you keep doing this, even if you start out with 20k tortoises on an island, eventually you run out.
So on Pinta Island, for example, everyone thought their tortoises were extinct bc no one saw any after the early 20th century, but surprise! Out of nowhere in 1971, a big beautiful boy appears!
Enter Lonesome George. Look at that neck!!!! He's the only Pinta Island Tortoise in the world and scientists and conservation experts are scrambling to figure out what to do! We thought they were extinct but now there's just One More???
So everyone's studying him and trying to get him a girlfriend and hoping somehow we can have a miracle and try to bring back this tortoise from the razor's edge of extinction.
Unfortunately, George never had offspring. He passed away in 2012, and the Pinta Island Tortoise was once again declared extinct. He was already full grown when he was discovered, so he could have been anywhere from 80-120 years old.
So this is the low point in the story. No tortoises, no chance. Until!!!!!!! 2015! Down on Isabela Island, near Wolf Volcano. What sort of tortoises are these? They have these crazy hump shells, not like the native Isabela Tortoises should have....
Turns out!!!!! There's a bunch of hybrid tortoises down here, but they have a ton of features and genetics from our bestie the extinct Pinta Island Tortoise!! We know from historical records that sometimes sailors would pick up tortoises on one island and drop them off on another.
So then it's like,, can we breed these descendant tortoises to get more Pinta features and reintroduce them to the right island ??
Meanwhile
On Wolf Island, more out-of-place hybrid tortoises have been spotted! (This is... early 2000s?) These ones look distinctly like the Very Incredibly Extinct tortoises from Floreana Island
We're talking, like, some of the most recent sightings of these Floreana Tortoises in the wild being recorded by Charles Darwin in the 1830s. We're talking more than 180 years of extinction. And there's little tortoises with the same shell shapes and features wandering around way over on Wolf Island!!!
Again. Sometimes old-timey sailors would drop off tortoises in weird places. But like!!!! These hybrid tortoises are descended from the Floreana lineage!! No one has seen these suckers in two centuries and their little descendants are still alive and kicking!
Now, Floreana Island,,, got put through the wringer. Ecologically, it was just a mess. We're talking a bajillion invasive species, species going extinct left and right. It was one of the most frequented islands by whalers back in the day, and it's taken decades of hard work to even begin to undo the damage. There's a reason the Floreana Tortoises went extinct, that's all I'm saying.
But so now we have these Floreana lineage tortoises (not pure Floreana Tortoises blood, that's gone now, but very close!) and we've got a Floreana Island that's been cleaned up and a whole team of ecologists who are very, very excited.
It's going to take a lot of planning to reintroduce these tortoises, though. We've got 15 of these Floreana lineage tortoises who still have a mix of traits, we want to end up with thousands of tortoises, and we can't just stick tortoises back on Floreana yet bc the invasive rats, feral cats, dogs, etc all love eating baby tortoises and tortoise eggs
So thus begins a decades-long project to raise sturdy tortoises with as many Floreana traits as possible and get them big enough to safely release onto an island that's still trying to get its rat problem under control.
All of this culminating in the release of 158 tortoises (aged 12-14, so they're all big enough to stay safe) on February 20th, 2025
After nearly 200 years without any tortoises on the island, Floreana had its tortoises back!
The young tortoises, each weighing between 30-50 pounds, had to be carried to the release site on foot by park rangers and volunteers. (link to video)
So much work went into preparing for this day, and this isn't the finish line! The Galapagos Conservation Trust plans to release hundreds more tortoises in the coming years, and to continue efforts to rebuild the ecosystem! Other native animals are making a comeback, like the Galapagos Rail, a bird who hasn't been seen in 190 years! We thought it was extinct!!! But as the island recovered they've reappeared!
There's so much thought that's gone into releasing these tortoises. They released them in February to take full advantage of the rainy season. The long term plan to handle the rats is timed to wrap up in the next 12 years before the new Floreana Tortoises are old enough to lay eggs. This is such a huge win for conservation in general and Galapagos conservation in particular!!!! This is groundbreaking, and it happened 12 days ago.
So for today, there's no Pinta Island Tortoises on Pinta Island. They're still extinct, and Lonesome George was the last pure-blooded Pinta Island Tortoise.
But two weeks ago there weren't any Floreana lineage tortoises on Floreana Island either. Things will never be exactly the same as before, but the ecosystem and the birds and the grasslands are going to love those tortoises. Recovery takes time, and nature is incredible at bouncing back, especially when people are willing to help move things along.
I really do believe that one day, Pinta Island will have charming, long-necked and bowed-backed giant tortoises again. I feel so grateful to live in a world of amazing creatures, and amazing people who dedicate decades to helping them.
