Residents of Loreto, Baja California Sur, are collecting signatures and planning street protests against a presidential decree that would designate their small coastal town as a cabotage and deep-water port. The opposition, which includes fishermen, dive operators, and environmental groups, argues the Loreto port decree threatens one of Mexico’s most protected marine ecosystems and was issued without any community consultation.
Organizers gathered at Parque Exploradores in Colonia Exploradores to launch the petition drive and plan what they call peaceful civil resistance. A public demonstration is scheduled for 7 a.m. Wednesday at the marina. The goal: pressure the municipal government to oppose the federal decree before any implementation begins.
Loreto’s Marine Park Holds UNESCO and RAMSAR Protections
Loreto sits at the edge of the Parque Nacional Bahía de Loreto, a marine park established by federal decree in 1996. The park covers roughly 206,000 hectares of the Sea of Cortez, including the islands of Coronados, Del Carmen, Danzante, Monserrat, and Santa Catalina. In 2005, UNESCO inscribed the Islands and Protected Areas of the Gulf of California as a World Heritage Site, a designation that encompasses the Loreto park.
The region also carries protections under the RAMSAR Convention, an international treaty for the conservation of wetlands and coastal habitats. Mexico signed that treaty in 1986. Together, these layers of protection have shaped Loreto’s identity as a low-impact ecotourism destination rather than a commercial shipping hub.
The presidential decree would change that trajectory. Cabotage ports handle domestic maritime freight. Deep-water (altura) ports handle international cargo and large cruise ships. Converting Loreto into either category would require infrastructure capable of receiving vessels far larger than the fishing pangas and small tour boats that currently use the harbor.
Mayor Paz del Alma Ochoa Amador endorsed the decree, saying it would place Loreto “in a new international dimension” and open commercial and tourism opportunities. She pointed to existing infrastructure at Puerto Escondido, a sheltered harbor about 25 kilometers south of Loreto’s center, as the likely site for expanded port operations. Puerto Escondido already has a small marina and a FONATUR (Mexico’s national tourism development fund) master plan dating to the 1980s that envisioned large-scale resort and marina development. That plan was never fully realized.
Blue Whale Absences Heighten Environmental Alarm
The timing of the decree has deepened local anxiety. Residents report that blue whales, which typically pass through the Loreto Marine Park between January and March, were largely absent from local waters this season. Blue whales are the largest animals on Earth, and their annual presence near Loreto supports a whale-watching economy that draws visitors from the United States, Canada, and Europe.
Scientists have not formally linked the whale absences to any single cause. But for Loreto residents who depend on marine wildlife tourism, the missing whales are a warning sign. Increased vessel traffic, underwater noise pollution, and construction associated with port development could compound stress on species that already face pressure from warming ocean temperatures and changing prey distribution.
The Sea of Cortez, which Jacques Cousteau famously called “the world’s aquarium,” supports over 900 fish species and roughly a third of the world’s marine mammal species. Loreto’s stretch of that sea is home to sea lions, dolphins, whale sharks, manta rays, and five species of sea turtles. Commercial port operations elsewhere in Mexico, including the expansion of Manzanillo and Lázaro Cárdenas on the Pacific coast, have brought dredging, fuel spills, light pollution, and habitat disruption to previously quieter coastlines.
No Public Consultation Preceded the Decree
Opposition leaders say the decree appeared without any prior dialogue. Mexican law requires environmental impact assessments (MIA) before major infrastructure projects in protected areas. SEMARNAT, Mexico’s environment ministry, and CONANP (the national commission for natural protected areas) are responsible for evaluating whether port development is compatible with existing conservation designations.
Residents say neither agency has issued public statements about the Loreto decree. That silence has fueled distrust. Loreto’s population is roughly 20,000, and many families have fished these waters for generations. Local fishing cooperatives harvest clams, snapper, and yellowtail under permits tied to sustainable catch limits. A deep-water port could bring industrial-scale vessel traffic into the same waters where pangas set their lines each morning.
Loreto also hosts a significant community of American and Canadian retirees, many of whom settled there precisely because the town offered calm waters, accessible diving, and world-class kayaking without the cruise ship crowds found in Cabo San Lucas. Property values along the Loreto Bay corridor and near Nopoló, a planned resort zone south of town, are closely tied to the area’s reputation as an unspoiled destination.
Wednesday’s 7 a.m. demonstration at the marina will be the first organized public action against the decree. Organizers say they plan to deliver their petition signatures to the municipal government and demand that the ayuntamiento (city council) formally oppose the federal plan. The story was first reported by Colectivo Pericú.
