Rewilding: Restoring Ecosystem & Community

Rewilding, once a novelty idea, has been scaling and we are gratified to see Argentina’s progress:

‘Fixing the Damage We’ve Done’: Rewilding Jaguars in Argentina

Bringing back the top predator to Argentina’s wetlands could restore the health of an entire ecosystem. But inducing five felines with troubled pasts to hunt, and mate, is not easy.

IBERÁ NATIONAL PARK, Argentina — They had a big job to do, drafted as the first few jaguars to be reintroduced to Argentina’s wetlands after more than seven decades of absence.

Capybaras, a giant rodent, at the park.

But they were a troubled bunch.

Tobuna came from an Argentine zoo and was fat and lethargic, in the twilight of her reproductive life. Her daughter, Tania, had been hidden from view in the same zoo because a tiger had mauled one of her legs as a cub.

Nahuel required custom dental work to ease the exasperating toothache that made him constantly grumpy, and never in the mood to mate.

Then there was Jatobazinho, who had stumbled into a rural school in neighboring Brazil in 2017, severely dehydrated and famished, having lost the ability to fend for himself in a region where farmland gobbles up more jungle canopy each year.

“They all had pretty traumatic stories,” said Sebastián Di Martino, a biologist who oversees conservation projects at the Rewilding Argentina Foundation, an initiative to restore the health of the country’s ecosystems by reintroducing species wiped out by human activity.

But in the tough business of rewilding, where obtaining breedable animals is often costly and logistically vexing, beggars can’t be choosers.

So Mr. Di Martino was thrilled to get any and all jaguars for the most challenging phase of a yearslong effort to create vast wildlife sanctuaries across Chile and Argentina.

For these imperfect jaguars, most of whom came from zoos, the splendor of their new home, Iberá National Park, must have seemed like paradise, filled with quarry.

On a recent visit, packs of howler monkeys looked like acrobats as they swung from tree to tree, yelping loudly. Swamp deer and capybaras grazed placidly as storks cruised overhead.

The jaguars aren’t the park’s only meat eaters. When kayakers glide down narrow streams, they must navigate around stoic caimans, absorbing the waning afternoon rays.

The idea of rewilding jaguars grew out of a project of Kristine and Douglas Tompkins, who ran the outdoor equipment and clothing companies Patagonia and the North Face before turning full time to environmental causes.I

n the 1990s, they began snapping up millions of dollars worth of land in the Southern Cone of South America. The goal of the American couple (Mr. Tompkins died in 2015) was to acquire the first building blocks of what would eventually become national parks.

But it struck them early on that simply halting the degradation of forests felt insufficient.

“Landscape without wildlife is just scenery,” Ms. Tompkins heard someone say soon after she and her husband bought an old cattle ranch in Argentina’s Corrientes province in 1998, which later became part of the Iberá park, tucked in the country’s northeast corner. “For us it was an epiphany and an opportunity.”

Across the Southern Cone, which includes Brazil, ecosystems are perishing at a staggering rate. Loggers, miners and farmers raze vast areas of the Amazon and other biomes each year, turning more and more emerald green canopy into grasslands.

The enormous scale of destruction across the region can make even Iberá, and its some 5,000 square miles of swamps and lakes, feel like a very small-scale utopia in comparison.

And bringing back jaguars to this bucolic landscape seems like just a tiny advance against an overbearing current.

The difficulty of making a difference is not lost on the conservationists who spend their days and nights at the remote sanctuary obsessing over how to get the jaguars, giant river otters and giant anteaters to mate — and ultimately to survive on their own.

But it’s a challenge they’re willing to accept.

“We can’t just be in the trenches resisting,” Mr. Di Martino said. “Now more than ever we have to go beyond conservation and restore, which means going to battle.”

The battlegrounds the Tompkinses picked have at times been rather hostile. As they began acquiring land, they were often greeted with suspicion.

In Corrientes province, some warned that the American couple would bottle up the area’s spring water and leave behind a parched wasteland.

“There were rumors they were going to take all the water all the way to the United States,” said Diana Frete, a deputy mayor of Colonia Carlos Pellegrini, a tiny town that serves as a gateway for the wetlands. “There were a lot of doubts and distrust.

”But the naysayers were proved wrong as the conservation efforts at Iberá, and the buzz surrounding the jaguars’ return, transformed the park into an emerging tourist destination.

“This was a town where everyone used to leave,” said Ms. Frete, noting that now some 80 percent of her constituents work in tourism. “Today, we’re better off tying our fate to protecting nature.”
