Los Cabos Mayor Christian Agúndez announced authorities have shut down a construction project at a property known as San Miguelito after inspections on May 11 revealed illegal land clearing, removal of native vegetation, and unauthorized building near the Sierra La Laguna Biosphere Reserve. The Sierra La Laguna construction shutdown targeted a proposed “species reproduction and conservation center” promoted by the Hermandad en Armonía Foundation, a project that Agúndez said violated urban and environmental regulations despite being framed as a conservation effort.
“The removal of native forest vegetation was detected without the rescue and management measures required by law,” Agúndez said. “Although the property lies outside the boundaries of the Biosphere Reserve, the project remains subject to current urban and environmental regulations, which were ignored.”
The mayor said he has filed formal complaints with Profepa, Mexico’s federal attorney for environmental protection, to begin legal proceedings over alleged damage to protected species and arid ecosystems.
Sierra La Laguna Has Faced Repeated Development Pressure Since 2012
The Sierra La Laguna Biosphere Reserve spans roughly 112,000 hectares of mountain terrain in the southern tip of the Baja California peninsula. UNESCO designated it a biosphere reserve in 2003, recognizing it as the only well-preserved dry forest on the North American Pacific coast. The reserve shelters more than 900 plant species, at least 30 of them endemic, along with threatened wildlife including the mountain lion and the endemic Baja California rock squirrel.
But the reserve’s protected status does not extend to all surrounding land. Private parcels adjacent to the buffer zone remain subject to municipal and state environmental rules, not federal reserve protections. This legal gap has created a pattern of conflict. Developers and foundations acquire land near the reserve boundary, then begin projects that impact the broader ecosystem without triggering the federal review that construction inside the reserve would require.
Profepa has struggled to keep up. The agency covers all of Baja California Sur with a small regional office, and its enforcement actions in the state have historically focused on marine violations along the coast rather than inland habitat destruction. Between 2018 and 2023, Profepa issued fewer than a dozen closures related to terrestrial habitat damage in BCS, according to its annual reports. Fines for environmental violations in Mexico often amount to tens of thousands of pesos, sums that are minor compared to the value of development land near Los Cabos.
The San Miguelito case follows a pattern. In 2022, community groups flagged unauthorized road construction on a private ranch bordering the reserve’s southern buffer zone. In 2019, plans for a luxury eco-lodge near the town of Santiago drew protests from local ranchers who said the project would divert water from the aquifer that feeds the sierra’s downstream communities. Neither project resulted in significant federal penalties.
Helicopter Flights and Heavy Machinery Triggered Community Alarm
The shutdown followed weeks of escalating public pressure. The Association for the Rescue of Peoples, Traditions and Economy reported that starting April 30, roughly 14 helicopters per day were transporting steel beams into the Sierra La Laguna core area. The group released video footage showing heavy machinery conducting clearing operations at the San Miguelito property.
The scale of the airlift alarmed residents and ranchers in communities near the reserve. Santiago, El Triunfo, and San Bartolo sit downstream from the sierra and depend on its watershed for drinking water and small-scale agriculture. Local ranchers have said they will continue protests until the environmental threat is fully eliminated.
The Hermandad en Armonía Foundation described the project as a center for species reproduction and conservation, but Agúndez made clear that the conservation label did not exempt it from permitting requirements. “In this administration, development is only possible with strict respect for the environment,” the mayor said. “Anyone who acts outside the law, or threatens life, water or our protected natural areas, will face the full force of the law.”
Water Supply and Ecotourism at Stake for Southern Baja
The sierra’s watershed feeds multiple communities across the Los Cabos municipality. Rainfall captured by the mountain forest recharges the underground aquifers that supply Santiago, San José del Cabo, and surrounding agricultural areas. Any large-scale vegetation removal on adjacent land risks reducing the infiltration capacity that keeps those aquifers viable, especially during drought years.
Sierra La Laguna also anchors a growing ecotourism economy. Guided hiking, birdwatching, and multi-day treks through the sierra’s oak and pine forests draw visitors from Los Cabos resorts year-round. Tour operators based in Santiago and San Bartolo rely on the reserve’s intact habitat as their primary selling point. Unauthorized clearing near the reserve boundary threatens the visual and ecological integrity that sustains those businesses.
The case now moves to Profepa for federal review. If the agency confirms environmental damage, it can order restoration of the cleared land at the foundation’s expense and impose fines. Profepa can also refer the case for criminal prosecution if it finds evidence of harm to federally protected species. Residents and ranchers have said they plan to maintain pressure through organized protests until formal legal proceedings conclude.
