Blue Carbon Farming in Baja

The southern reaches of Laguna San Ignacio in Baja California Sur, Mexico, may be the easiest places on the peninsula to get lost or hopelessly stuck.

Located west of the jutting escarpments, layered peaks, and hidden canyons of the Sierra de Guadalupe are “treacherous sand dunes, salt flats, and mud of a no-man’s land.” Surfers have been passing over these mud, sand, and dusty tracks southward to San Juanico or Scorpion Bay for decades.

“Take the wrong turn and you end up on a 20-mile detour that leads to a salt flat crossing filled with water and mud so thick that even walking is difficult,” I wrote in Saving the Gray Whale back in 2000. In the early 1990s, my wife Emily and I spent a few months living there while carrying out research on gray whale conservation. We got stuck and lost in our 1987 Ford F150 in the Lagoon’s southern salt flats plenty of times.

Today, the gray whale lagoon is part of the 6.2 million-acre federally protected El Vizcaíno Biosphere Reserve, which is also a UNESCO World Heritage site. The remote lagoon is inhabited by salty fishermen and their families, many of whom make their living running whale watching camps during the winter months.

This isolated and wild region is also ground zero for an ambitious and innovative effort to help sequester carbon via mangroves, the aquatic plants that line the wetlands and embayments of the central and southern Baja California peninsula and are found among the tropics.

“The mangroves of Baja are unusual because they are desert mangroves and found in only a handful of regions around the world,” says Tannia Frausto, WILDCOAST Climate Change Manager.

Mangroves are a type of blue carbon ecosystem that sequester atmospheric carbon at a rate five times faster than terrestrial forests while storing up to 50 times more carbon than forests on land. They’re of special interest today as we work to reverse the impacts of the past 100 years of releasing excess carbon into the atmosphere. Our coastal ecosystems are incredibly efficient at removing harmful amounts of carbon from the atmosphere and can store it for thousands of years, making these areas key in the fight against climate change.

“If we are to address climate change, it is imperative that we not only reduce emissions globally. We also have to conserve and restore the natural ecosystems that help us sequester carbon and adapt to climate change. In the case of mangroves, these ecosystems protect shorelines against rising seas levels and dangerous chubasco storm surges as well as sequester carbon,” says Frausto.

With the support of SeaTrees, WILDCOAST is working with women in Laguna San Ignacio to plant 40,000 mangroves over 25 acres of tidal zones, creating a habitat suitable for fish, shellfish, wildlife, and adapting to and mitigating climate change. “Mujeres de El Dátil” are trained in mangrove environmental services, seedlings collection, and planting techniques, as well as monitoring and maintenance of restored sites.

“Our collective efforts in the Lagoon provide a clear model for how we can work at the local and global level to address climate change through natural solutions,” says Frausto

It’s all part of a larger project to protect mangrove forests throughout Mexico. Through legal protection and management, WILDCOAST has helped to conserve 38,336 acres of mangrove forests that store 3.5 million tons of carbon, equivalent to the emissions of 2.8 million cars driven in one year. As Frausto points out, it’s a natural solution to tackling climate change — a piece of the puzzle we can all put together now before it’s too late.

Five Reasons Why Protecting Coastal Oaxaca Matters

(Originally published in The Inertia) With the endless barrage of swell raining down on Oaxaca this time of year, the eyes of surfers around the world are always fixated on the elevator drops and deep barrels at Puerto Escondido. But right now with the World Surf League’s Corona Open Mexico running, the tranquil village of Barra de la Cruz has both the world’s best surfers visiting and a global gaze on the surreal sand bottom tropical cylinders of Oaxaca.

Oaxaca is more than just a destination for waves, though. It also contains globally important coastal ecosystems, a myriad of unique wildlife species, and vibrant indigenous communities. The undeveloped state of this wave-rich zone (with the exception of Puerto Escondido) and its unaltered watersheds and coastline contribute to the exceptional quality and diversity of point waves. That, in turn, fuels the rare ecological conditions that result in wildlife and rich ecosystems seen in few other locations in coastal Mexico.

Coastal Oaxaca is influenced by the Isthmus of Tehuantepec whose Tejuano winds and other biogeographic features have produced rare coastal dunes next to patches of tropical forest as well as upwelling in the Gulf of Tehuantepec, which in turn results in an amazing abundance and diversity of ocean life. It is these contrasts that make its protection vital, not just for surfing, but for the health of the oceans worldwide.

This also includes the continued well-being of Oaxaca’s residents, especially indigenous communities that depend on natural resources, many of whom still deeply feel the stinging loss of their villages from the development of the coastal resort city of Huatulco.

With all that in mind, here are five resources we must continue to protect to preserve the miraculous and stunning coastal resources of one of North America’s most unique regions:

1. Connected and Undeveloped Coastlines and Watersheds

The coast of Oaxaca offers up what is increasingly rare in a tropical Pacific Mexico that has been hammered by urbanization, coastal tourism development, pollution, and deforestation (especially in the states of Michoacan and Guerrero): undeveloped coastal ecosystems connecting mangrove wetlands to watersheds and tropical forests.

Looking southeastward from Barra de la Cruz, endless green mountain vistas of the Sierra Madre del Sur fill the view and culminate in the 12,200-foot Cerro Nube at its southerly edge. Just down the beach from Huatulco is the mouth of the Copalita River that offers up whitewater rafting and hundreds of thousands of acres of tropical forests, home to some of Mexico’s most important watersheds, now referred to as “water reserves.”

While Huatulco is obviously a tourist resort, its development included the formation of the 29,400-acre Huatulco National Park and the preservation of local coral reefs and coastal wetlands and forests. That forward-thinking conservation is unique among Mexico’s heavily developed coastal resort cities.

2. Coral Reefs

Coral bleaching is a threat to coral reefs worldwide. But somehow the corals of Mexico’s Pacific have not seen the type of damage faced by Australia’s Great Barrier Reef. The coral ecosystems of Huatulco National Park are the southernmost in Pacific Mexico and home to a wide variety of wildlife species. Unfortunately, they have been impacted by overuse from tourists. Currently, the organization WILDCOAST is working with Mexico’s National Protected Area Commission to train outfitters in best management practices and place mooring buoys around the most fragile reefs to prevent damage from anchor drops.

3. Sea Turtle Nesting Beaches

Starting in the summer months, especially Escobilla and Morro Ayuta, tens of thousands of olive ridley sea turtles arrive to lay their eggs on Oaxaca’s beaches. In Barra de la Cruz, the protected beach and RAMSAR Wetland of International Importance play host to the most important remaining population of nesting leatherback sea turtles in Mexico. These marine reptile leviathans that face extinction due to threats caused by industrial and commercial fishing, only leave the ocean to lay their eggs (and only the females).

The sea turtle activity in Oaxaca is remarkable given that the now hipster tourist village of Mazunte down the coast from Puerto Escondido was once the site of Mexico’s notorious legal sea turtle slaughterhouse. Sea turtles have come back thanks to government protection, the cooperation of local communities who benefit from sea turtle conservation, and the preservation programs of the Mexican Sea Turtle Center at Mazunte.

4. Blue and Green Carbon Ecosystems

The mangrove wetland and tropical forest ecosystems found widely in Oaxaca help to store vast amounts of carbon to mitigate climate change.

“By preserving natural ecosystems, the carbon they have already sequestered remains stored in the ground. When these blue and green carbon ecosystems are destroyed, they end up releasing carbon dioxide into the atmosphere, worsening the climate crisis,” affirms WILDCOAST Associate Director Zach Plopper. “So we need to not only protect every inch of Oaxaca’s treasured natural ecosystems for the sake of the people and wildlife that thrive there but for the sake of preserving our planet.”

These ecosystems are also home to humpback whales off the coast, along with jaguarundi, jaguars, anteaters, resident and migratory birds, deer, iguanas, and rare and other threatened marine species.

5. Globally Unique Surf Spots

There is increasing recognition of the need to safeguard globally unique surfing sites as protected areas and World Surfing Reserves. The sand-bottom breaks of Oaxaca, which include Punta Conejo, now threatened by the proposed expansion of the port in Salina Cruz, are more than worthy of permanent protection. They are rare and treasured ecological features, coastal and marine ecosystems, wildlife habitats, and recreational, cultural, and economic resources that help to drive an important part of the local economy in Oaxaca.

Without more formal conservation protections, Oaxaca will fall prey to the same forces that have ravaged coastlines and natural ecosystems around the world. There is still time to make sure that this magical coastline retains its extraordinary resources and raw beauty so local communities and surfers continue to benefit from and enjoy Oaxaca’s natural wonders.
