In an Era of Hardening Borders, Wildlife Corridors Bridge Peoples and Species
From Costa Rica to Colorado, wildlife corridors have been about the connections people make when they care about animal mobility.
Jun 14, 2026
Driving on the Interamerican Highway from Monteverde Biological Reserve to Rincón de la Vieja National Park, I couldn’t help but notice a series of rope bridges that crossed the six lanes of traffic. Each crossing structure featured traffic warning signs with silhouette images of monkeys or sloths as nonstop flows of diesel semitrucks and electric cars zoomed by.
Costa Rica is known for its protected areas, which cover one-third of the country and function as core zones for conservation, but the “green republic” should also be recognized for its corridors. What started as an NGO effort in the 2000s when organizations like Kids Saving The Rainforest started installing aerial bridges to improve habitat connectivity later became national policy with a 2024 presidential decree requiring electrical companies to build crossing structures so that animals like howler monkeys and kinkajous avoided electrocution from using power lines. These monkey bridges also keep tropical rainforest more intact for mobile creatures.
Beyond Central America, wildlife corridors are popular in the western United States. According to recent surveys from the Environment America Research and Policy Center and the Pew Charitable Trust, respondents approve creating more wildlife crossings at rates of 85-90%. And that support spans the political spectrum. In March 2026, the Idaho State Legislature passed Senate Concurrent Resolution No. 124, officially supporting the development of wildlife crossing infrastructure, such as highway overpasses and underpasses, to reduce animal-vehicle collisions. In December 2026, California’s Wallis Annenberg Wildlife Crossing is set to be completed across 10 lanes of Los Angeles freeway, making it the largest structure in the world.
Wildlife corridors could receive a financial boost by the bipartisan BUILD America 250 bill, considered by US House Transportation and Infrastructure Committee this week. If passed, it would increase funding for the Federal Highway Administration’s very popular Wildlife Crossings Pilot Program (WCPP) to $80 million annually ($400 million total). The 2021 Infrastructure Investment and Jobs Act allocated $350 million to 35 projects across 30 states, but demand far exceeded with $500 million in requests.
Today, the benefits of conserving wildlife corridors might be just as much about the social as the biological.
If we’re living in a worldwide golden age for wildlife corridors, where did this idea come from? I trace the origins of this dominant conservation strategy in my new book, Borders of Biodiversity: How Gray Wolves, Monarch Butterflies, and Giant Sequoia Transformed Large Landscape Conservation, published by University of North Carolina Press.
In the 1970s and 1980s, new technologies provided windows into animal mobility. For wolves, radio- and satellite- telemetry allowed US biologist Diane Boyd and Canadian biologist Paul Paquet to track the interchange of dispersing juveniles along the Rockies. For example, Boyd collared wolf #8551, named Kay, west of Glacier National Park; the wolf turned up six months later dead after it was legally shot near Pouce Coupe, British Columbia. The 600-mile movement northward was interesting scientifically because it was two-thirds of the way to the Yukon Territory, but Kay’s movement also had major conservation implications. Wildlife corridors facilitated wolf dispersals; transborder dispersals could facilitate wolf recovery under the Endangered Species Act.
In the 1990s, wildlife corridors were thought of as proactive tools against habitat fragmentation. Responding to Boyd and Paquet’s work, conservationists in Alberta, British Columbia, Idaho, Montana, and Wyoming created the Yellowstone to Yukon Conservation Initiative in 1993 to keep core areas—like Yellowstone National Park or Banff National Park—connected. Projects included lobbying the Canadian government to build wildlife overpasses and underpasses along the Trans-Canada Highway, which Y2Y founder Harvey Locke called the “Berlin Wall of Biodiversity” for its high rate of wolf and elk fatalities. Or investing in predator-deterrence tools like range riding and electrified fladry fencing for ranching communities so wolves and grizzlies could use rural spaces as biological passageways.
By the 2000s, however, wildlife corridors were also understood to help with climate adaptation in a warming world. A scientific meta-analysis documented that of 4,000 animals recently tracked, almost three-quarters of them shifted their ranges to cooler lands or waters. Terrestrial species, on average, were moving 12 miles (or 20 kilometers) every decade toward the poles. Animals relocate to adapt.
Today, the benefits of conserving wildlife corridors might be just as much about the social as the biological. In 2012, Ben Bobowski of Rocky Mountain National Park and Yaxine María Arias Núñez of Santa Elena Biological Reserve created a series of personnel exchanges between the two protected areas called the Naturalmente Juntos-Naturally Together Project. Their connection was based on bird banding studies that revealed 150 bird species, like yellow warblers, migrated along the Continental Divide between Colorado and Costa Rica. In 2015, Rocky and Santa Elena entered a formal sistering agreement.
From Costa Rica to Colorado, wildlife corridors have been about the connections people make when they care about animal mobility. In an era of border-hardening nationalism, corridors can help people of different nationalities facilitate solidarities among shared species.

Waging a Nonviolent Civil War Against Borders
What we choose to love fully and unconditionally is Planet Earth itself—a planet without borders—and all who live within it.
Feb 01, 2026
And here I am, an American, staring at the border again... and slowly coming to realize the paradox of it. Borders don’t actually exist. They’re invisible lies. They’re also virtually everywhere.
Consider the border Alex Pretti crossed on January 24, on a street in Minneapolis, as he stepped between some US Border Patrol agents and the woman they had just pushed down. He crossed the border that separates ordinary people from the federal Proud Boys (or whoever they are), the masked invaders who were occupying the city to enforce The Law. Pretti interfered with them! He dared to try to protect the fallen woman, who herself had just crossed the same border. In so doing, they both went from being ordinary citizens to “domestic terrorists.”
“Yet our greatest threat isn’t the outsiders among us, but those among us who never look within.”
The words are those of poet Amanda Gorman, who wrote a poem honoring Alex Pretti after the agents shot him, almost 10 times. Another killing! Oh my God! Another cut to the American soul—a cut, by the way, that comes with complete immunity, according to Team Trump. They’re waging civil war against those who cross the border that separates right from wrong. “Fear not those without papers,” Borman’s poem continues, “but those without conscience.”
Oh, let us evolve toward a trans-border world! This is the core of the American civil war that is now, seemingly, getting underway.
You know what? As terrifying as the idea of a new civil war sounds, I prefer it to something worse: a great national shrug and acquiescence to the Trump agenda. Immigration and Customs Enforcement (ICE), as so many people have pointed out, is acting like the Trump Gestapo, as his administration rids sacred (white) America of the brown-skinned other, who may or may not be immigrants. What matters is that they’re different from “real” Americans. Right?
Regarding the whole concept of the border: It seems so real and viable until you start questioning it, which includes looking into its history.
As Elisa Wong and Raymond Wei write:
The way we think of borders today, as firm boundaries that are violently enforced, is a relatively new thing, and we would argue it doesn’t serve humanity’s best interests. While ‘strong borders’ are often argued as a necessity for our security, we think they limit humanity’s potential as a global community.
In ancient times, rivers, oceans, and mountains marked the boundaries of territory... As humans began building kingdoms and empires, more walls began to form, thus more firmly delineating borders.
And in Medieval times, from around 1000 to 1700 AD, European kingdoms started engaging with each other in a state of unending warfare, violently squabbling over the limits of their territory. And plunk! Global borders were created, and whole contents started getting divided almost randomly into European territorial possessions.
“At the Berlin Conference in 1884,” Wong and Wei write, “European leaders met to carve up Africa for themselves, which split local tribes across arbitrary lines and laid the groundwork for ethnic conflicts that still rage today’”
Oh, let us evolve toward a trans-border world! This is the core of the American civil war that is now, seemingly, getting underway. This is why protesters are flooding the streets in Minneapolis and across the country. This is why they’re enduring pepper spray and tear gas and flash bang grenades. This is why some people are being killed. But the rational—effective—response to violent aggression is not counterviolence.
“Anger and hatred are natural in response to such atrocities,” David Cortright writes, “but it is essential to avoid causing physical harm, to maintain a nonviolent intention and commitment despite increasing government provocation. A major outburst of protester violence would be disastrous, diverting attention from the message of support for victimized communities. That’s exactly what the White House is hoping for—to cover up ICE abuses, reinforce their lies about violent protesters, and justify additional domestic militarization.”
And he quotes—who else?—Martin Luther King: “Hatred multiples hate. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Violence multiplies violence.”
Yeah, that’s the world as we know it: endless war. But America’s new civil war must not—will not—go that way. “Loving ICE” doesn’t mean accepting their actions or their purpose, but rather, challenging it head on, courageously and nonviolently. What we choose to love fully and unconditionally is Planet Earth itself—a planet without borders—and all who live within it. Yes, that includes ICE agents. It includes Donald Trump. But loving them also means standing up to them—and handing them their conscience.

How Immigrant Fiction Can Reshape American Realities
As the politicos do their darndest to render the Statue of Liberty little more than a New York City tourist trinket, what can American immigrant literary fiction offer our nation in terms of imagining a more welcoming, inclusive, and promising future?
Aug 20, 2025
Immigrants have been reshaping America since the pilgrims landed on Plymouth Rock. Or perhaps earlier than that fateful day in 1620, if you count Viking excursions dating back to 1021 and Spaniards landing in Florida in 1513. After the subjugation and genocide of the continent’s Indigenous people, and the establishment of the United States, wave after wave of newcomers from all over the globe, forced and unforced, have helped build what so many call “a nation of immigrants.”
Despite those facts, immigration has always been a topic of debate and a lightning rod for racism, xenophobia, and nationalism, a tool of political manipulation that appeals to people’s worst instincts and fears. Since the political rise of Donald Trump and his descent down that golden escalator in 2015, the debate on immigration and the US-Mexico border has shifted considerably to the right, after decades of centering on moderate concepts calling for comprehensive immigration reform and enhanced border security.
In the 2024 election cycle, both parties have skewed further in the same direction, narrowing the debate and placing immigrants and their advocates in an ever-tightening corner, with Republicans calling for mass deportations and Democrats supporting limits to asylum for refugees and backing away from providing public services (such as health and education) to undocumented immigrants and their children.
As the politicos do their darndest to render the Statue of Liberty little more than a New York City tourist trinket, what can American immigrant literary fiction offer our nation in terms of imagining a more welcoming, inclusive, and promising future?
Humanity, New Visions, and Hope
We are all human beings. To me, that’s what any good book reminds us of at its core. Authentic immigrant stories chronicle the desperation, urgency, and desire for safety and progress that drive immigrants to America’s shores in the first place. Immigrant and multicultural literature explore the process of becoming American, the rifts between immigrant generations and those born and raised here, and the sacrifices and rewards experienced by families and communities through acculturation, assimilation, and simply the act of living in a country full of promise yet also torn apart by a legacy of racism and discrimination. But, no matter where the readers and the writers come from, when one walks in the shoes of another, one gains empathy. In this way, immigrant literature builds bridges that foster unity in our shared humanity and multigenerational American experience.
Before embarking on my own journey as a writer of literary fiction steeped in the immigrant experience, some of the books that most deeply touched me were likewise immigrant or multicultural narratives. Even though they may not have been specifically about the Latino perspective, I saw myself and my family reflected in their characters’ struggles and dreams. At an early age, that experience as a reader opened my mind to cultures other than my own.
I did not get to New York City until I was a college student in New England, but I felt like I’d been there as a child making Jewish friends in the tenements of Henry Roth’s Call It Sleep. I never spent a night in Harlem, but I could feel the dust on the floorboards and the tension between father and son in James Baldwin’s Go Tell It on the Mountain. I’d never seen a ghost, but I saw myself and began to recognize my own voice as a writer in Gabriel Garcia Márquez’s One Hundred Years of Solitude.
When we recognize our genuine shared God-given humanity, the man-made machinations of maps fall into the shadows and the hope of who we could be and what we could do if we embrace each other lights the way in a blaze of glory.
When we see each other as more the same than “other” and “different,” we see that artificial constructs—such as borders and citizenship and legal documents providing permission for human beings to live in peace on various patches of the Earth’s soil drawn on maps by men who waged and won wars decades or centuries past—are just that: artificial, man-made, and by their very nature should be malleable. To connect and lift each other up, we must work toward more togetherness and less division.
Immigrant fiction is a laboratory for the creation of new visions for where we could go as a nation, as a continent, as a people united rather than divided. Just like science fiction has laid out blueprints for many of the high-tech devices and inventions that are now either fixtures in our daily lives or soon to revolutionize the way we live, immigrant fiction can help us imagine, envision, and thus create a new reality.
In my novel, The Resurrection of Fulgencio Ramirez, I imagine a world where a multigenerational utopia is built on a city that straddles both sides of the Rio Grande, a place where not just the borders between nations fade away but also those between life and death. In a manuscript I’m currently working on, I envision an America where someday there will be no borders at all. The walls and fences will be pulled down. The coils of razor wire will be retired. The militarized forces will be deployed elsewhere, far from the fertile farmlands of the Rio Grande Valley, far from the vast and perilous Chihuahuan Desert. The river will gleam with promise and flow in tranquility as it snakes its way like a shimmering serpent toward the Gulf of Mexico. Bridges will be built. And people will move safely back and forth, north and south, along with trade and commerce. When this happens, cultural harmony will rise, economies will boom, and illegal narcotics, weapons, and human trafficking will become ancient history.
Imagine that. Instead of masses huddled along fences and politicians saber rattling and fearmongering, countries will work together to solve the hemispheric problems that they cannot solve alone. Stronger than ever, fueled by access to opportunity and more affordable labor, the combined Americas will be able to compete with the surging global powerhouses of China and India.
For that to happen, we must stop seeing the border as a problem and seize it as an opportunity. We need stories that inspire hope in us, faith that we can see past each other’s differences and find the common ground that binds us together: a love of family and freedom; a desire for each generation to do better than the one that came before; a respect for our fellow human beings regardless of where they were born, the color of their skin, or the language their mother whispered into their ears as newborn babies cradled in their arms.
We all have hearts that ache for love, minds that crave understanding, souls that yearn to be seen. This human connection—cognizant of the pain we all bear as living, bleeding beings but fiercely determined to cling to an optimistic view of the future we can share—drives the narrative arc of my new novel, The Border Between Us. It is the story of an immigrant family, of a young American raised on the border and kept afloat by the love of family and irrepressible buoyancy of the American dream. And many people who have read it have told me how they were touched by it in varied ways.
People didn’t focus so much on the border or the immigrant aspects when they shared their reactions. They mention seeing their own lives reflected in the novel: the strains of complex parent-child relationships, the balancing act between pursuing one’s own aspirations while living up to family responsibilities and obligations, the grief and hardship of losing loved ones before their time. When we recognize our genuine shared God-given humanity, the man-made machinations of maps fall into the shadows and the hope of who we could be and what we could do if we embrace each other lights the way in a blaze of glory.
Listen to me, America. I’m from the border, born and raised. I love the border. And, I believe the borders should be erased. Anyone supporting the proposed mass deportations (as well as the racial and ethnic profiling and vast detentions these would entail) should read Farewell to Manzanar, chronicling the mistreatment of Japanese-Americans during WWII. They should also do some research on the inhumane Operation Wetback, through which over 1 million Mexican migrant workers were deported in the 1950s. These are cautionary tales from our not-so-distant past.
We can be more than we are today as a nation and as a people. For that to happen, we must avoid the errors of the past, stop limiting ourselves, and expand our horizons. Until then, pick up some immigrant or multicultural fiction, learn from history, and imagine the possibilities. Someday, we can turn honest memories and empathetic visions into a new and more welcoming reality.
