Looking out the window of the 9-seater Cessna, I see a massive inlet of emerald-blue, mountains of green. This is the Golfo Dulce, the fjord-like southern gulf of Pacific Costa Rica. To the west is our destination, the Osa Peninsula – pristine, protected, primeval.
The Osa Peninsula is one of the most protected regions in the American tropics, and at the center of this protection is the crown jewel of Costa Rica’s national park system; Corcovado National Park.
On the approach to Puerto Jimenez, population 1,800, I see a complex coastline of isolated beaches, dense mangroves, twisty rivers, meadows, ranches, turquoise salt flats, small clusters of lonely sailboats. A Southern Lapwing takes flight from a palm that has bent downward into the water. No three-story buildings, no billboards. Just wild land and a small cluster of dusty streets and an airstrip. I’ve seen my share of the tropical Americas from the sky; tell me no more, it takes just a second to know heaven on Earth.

The Cessna takes a deep dive, it’s a short runway, and, according to the pilot about the trees on the approach, ‘they keep getting taller and taller every year!”
There is only one other airplane on the runway – a Cessna 4-seater. The pilot of this plane hands our luggage to the pilot of the other plane, ushers us out, and then takes off again. A few minutes later, we are in the air again. This time, overland across cliffs draped in blooming trees.
Ahead is a small runway carved out of the forest, between a Pacific coast beach and a steep, jungly cliff. This is Carate, formerly the airstrip for foreign gold-mining operations that once swelled this coastline with a population of 60,000. The creation of the adjacent Corcovado National Park forced the end of gold mining operations in the Osa Peninsula, and now there is just an airstrip, a convenience store, two lodges and a handful of homes.

My son, who has learned in the Spanish language since kindergarten, has never spoken the language outside of the classroom, and has been openly questioning why he can’t learn in English, like every other kid. But hearing our driver, who’s waiting for us at the airstrip, seems to pique his interest.
As we drive into the hills to our destination – Luna Lodge – something seems to snap into place. He, not us, understands our driver. We are in his 8-year old hands. For the first time in our lives, we depend on him.
Bay-headed Tanager at the lodge
Over the course of our stay, he will meet a variety of Spanish-speaking kids, all of whom seem as equally transfixed as my son with the lodge’s mascot dog. One of the Spanish-speaking kids explains to me the source of the dog’s visible scars. “Osa,” – that’s the dog’s name, “was walking in the jungle,” he says. “And suddenly a puma comes out of trees and bites her! Those are the teeth-marks of the puma!”
Later, another kid explains: “You see those scars on Osa? She was in the woods, chasing after a bird, but a pack of howler monkeys didn’t like that she was in their jungle, and they beat her up!”
And even later, I hear a third kid telling my son a variation of the story. This time, it’s, “Crocodile bite her!”
Kayaking the Peje-Perrito Lagoon, South of Carate.
On a cloudy afternoon, I take a walk with Kevin, one of the guides. A steep road, cut into a steep hillside; makes for complex geography and varied habitats: dense viney jungle, steep cliffs and river gorges. We are looking for Orange-collared Manakins, and so we diverge from the road into the forest.
We perch ourselves quietly on a hill, and I ask Kevin about which of the stories about Osa’s wounds is true. “Osa was asleep under the lodge porch,” he explains. “One of the guides found her struggling, almost dead. A huge boa constrictor had completely wrapped itself around her, and was biting her in two different places.” He pointed to his stomach and leg. “A guide and a guest were able to wrestle the snake off her and save her, but it was really close.”
While the story of the dog must surely have been passed along in a game of telephone, there is no doubt that a story of large, dangerous animals, brought close up in the form of a gentle, scarred dog, intrigued them all. As adults, we still view, and talk about these latin jungles through the stories of large, lurking animals. And if not large animals, then small, delightful birds. Kevin and I find the Orange-collared Manakin, high up on a tree branch. Just a little thing, with a puff of orange, and then it’s gone.

For however long I have been introduced to the idea of a vast corridor that would stretch from the southern states of Mexico through Panama, we always hear about it in the context of the jaguar. The Mesoamerican Biological Corridor would give the jaguar the space to roam that it needs, we are told. The explanation suffices; it works, it even manages to raise money to conserve more land.
But when conservationists, governments and patrons dream up these corridors, it really isn’t about jaguars, it’s about the biosphere; all of the living organisms in a given ecosystem. And the Osa Peninsula is really the symbol, in Costa Rica, of the idea that larger pieces of land need to be set aside for conservation. In a way, you might say that vast corridors of nature allow the many species – of bacteria, of fungus, of insects, of plants, of amphibians, reptiles and small mammals to flourish, creating the ecosystem upon which the jaguar, as well as humans, rely.

Many people talk about how the wildness of the Osa Peninsula is particularly intense; as if its wildness is spilling out of the trees. And this is actually true. Wildlife abounds in a way I have never seen anywhere else. Why is this?
For one, the Osa Peninsula is part of the thin isthmus where North and South America connected some three million years ago, creating an overlap of species from both continents. On top of that, this part of Costa Rica is ripe with abrupt changes in topography and climate, creating basins and ranges of habitat variations. These bands of habitat create spectacular chances for ecological diversity.

Lastly, most of the Osa Peninsula has remained, for the most part, largely unbroken jungle, almost free of development. There are no roads dividing up its interior. No towns, and almost all the farms and ranches exist only on the flat floodplains near the Golfo Dulce.
There are many other protected parks in Costa Rica. Over twenty-seven percent of the country is protected by private and public lands. But many of these parks are small, isolated islands of protection.

In the 1960s, Edward O. Wilson and fellow scientist Robert H MacArthur proposed the Theory of Island Biogeography, which argued that islands tend to have less species richness than continents, and that the larger an island, the likelier it was to hold a greater diversity of species. Small islands were also less stable than larger ones, as the small ecosystems increase the probability of extinction events.
Today, island biogeography has evolved into the study of insular biogeography, which expands upon the earlier theories, and looks at how well isolated ‘islands’ of habitat, surrounded by disturbed or unsuitable habitats, are able to maintain their diversity and ecosystem health. As the theory goes, a wild zone, surrounded by fragmented habitat – agriculture, suburbs, roads, mining operations – for example, will produce the island effect on a national park.

I love islands, of course, but islands are always clearly less diverse than mainlands. The Bocas del Toro archipelago on Panama’s Caribbean coast is a lovely place, but relatively empty of life. The Abaco Islands, of which I have often written, are missing a diversity of reptiles, simply because of an abundance of birds.
The theory of insular biogeography, with all of its faults and weaknesses, has propelled the case for larger national parks, and unbroken corridors, throughout the globe.
Look at Costa Rica on Google Earth, and you’ll see a patchwork of parks that exist as an isolated forest in a sea of humanity. Here at the edge of Corcovado National Park, you can see the robustness of life; the effect of vast, unbroken wilderness.

Corcovado itself has long segments of trails for backpackers and hikers; but it is essentially just one trail. The rest of Corcovado is inaccessible to all humans but biologists. And today, entering the park requires a licensed guide.
The notion of larger wilderness corridors is not radical in the Osa Peninsula. Lana Wedmore, who built Luna Lodge, also founded The White Hawk Foundation, which raises money to purchase ranch land adjacent to Corcovado National Park.

Lana’s enthusiasm for preservation is infectious. “There is no other place left on the earth that has so much biodiversity in such a small area, with a healthy ecosystem still intact,” she says.
The White Hawk Foundation, named after the rare raptors that circle above Corcovado, follows the premise that despite the park’s relatively large size, it is still an isolated wilderness that needs to be connected to larger wildernesses.

The foundation’s goals are modest; it’s a small foundation that hopes to expand the protected zone of Corcovado by purchasing ranches adjacent to the park. “We’ve raised over 10% of our goal, over $200,000 dollars,” Lana explains. The dollars needed to buy up the adjacent ranches is small, especially compared to the money that goes into protecting much smaller parcels of land in the US and Canada.
But Lana particularly piques my interest when she starts to talk about the bigger picture, beyond just the immediate expansion of Corcovado. “It would be very important to connect the parks of this region for many reasons. It could be a very important Biological Corridor for the animals to then go on into, for example, La Amistad International Park.”
La Amistad International Park is a preserved area split equally down the middle of the southern part of Costa Rica and the northern part of Panama. Imagine Corcovado linking up to this park and you can start to see how the idea of an unbroken chain of international preservation through the rich jungles of Central America is not so far-fetched.

We are preparing for our own hike into Corcovado National Park the next day, and the guests of the lodge who had completed the eleven-mile hike are loading Jane up with information, offerings of backpacks, tips on what to bring and how many extra pairs of socks to take. “Everybody needs three liters of water,” a guest explains.
The next day, we depart from the lodge and head north along a beach-side trail. We pass through misty coconut palm groves and dry coastal forests, populated by troops of monkeys.
Unlike anywhere else on Earth, you can walk for three days straight along the beach and not see a single human structure. We make it by midday to a half-moon bay, where Scarlet Macaws flock, and the green of the jungle bursts out onto the beach.

By this time of day, it’s sweltering along the beach. Here, we have lunch at the beach, quietly resting under shade. My son has been poking and prodding at small creatures with me since his toddler days, so I am not surprised when he looks closely at an ant and says, “this one has yellow spots on its back,” and of a hermit crab plodding along the beach, “this one is using a different type of shell than that one.”
But when, later in the sweltering heat, our guide and I find a tamandua scouring above in the branches, my son appears unimpressed. “This is the animal that so many people come here to see!” I try selling him the anteater’s qualities.

But actually, coming all the way to Corcovado to see a tamandua, a tapir or a monkey is like the children’s story of traveling to wild places. More of us should look at the yellow spots on the back of the ant, and the fungus on which it feeds, and the vines of which is calls home. Because the ants and the fungus and the vines are the foundation for the tamandua, the monkey, the jaguar, and us.
