Los Cabos reviews an Earth Army plan to seed bomb the Estero Josefino reforestation using a WWII aircraft, aiming to restore mangroves and protect water sources.
San José del Cabo, BCS.- The Los Cabos Municipal Department of Ecology and Environment is weighing a bold plan to boost Estero Josefino reforestation after receiving a proposal from the international NGO Earth Army. Founded in 2019, the group has already tested its seed-bomb technique in Guadalajara, Jalisco, and now hopes to bring the same strategy to one of the region’s most vital wetlands.
Earth Army’s approach blends low-tech and high impact. Volunteers load native tree seeds into small clay “bombs” and disperse them across deforested zones. For San José del Cabo, they propose using a repurposed World War II aircraft—once a military bomber—to scatter these seed bombs from the air. Officials are currently studying whether the plane’s load capacity and flight patterns will suit the estuary’s delicate ecology.
“They’re analyzing whether it’s feasible to bomb with the equipment they’re bringing,” said a department spokesperson. “It’s a World War II aircraft that was previously used for military purposes. Currently, they’re using it to bomb seeds to reforest selected areas.” Early site visits by Earth Army and municipal staff have mapped out flight paths and potential drop zones to maximize germination while avoiding damage to existing mangroves.
Before any aerial seeding can begin, Earth Army’s plan must clear two key steps: legal approval and endorsement from the Estero Advisory Council. Under local regulations, any reforestation effort in a protected wetland needs a detailed environmental impact report and a sign-off from the council—a body that brings together scientists, community leaders, and conservation officials. The Ecology Department is drafting the framework now, with a council vote expected in late summer.
If approved, Los Cabos could become a model for other coastal regions facing mangrove loss. “I believe it will be viable,” said Beatriz López, head of the Ecology Department. “But we must not forget that we not only have the Estero as a protected area. We can also think about the delegation of Santiago and Sierra de la Laguna, which we share with the municipality of La Paz and that is our main source of drinking water supply. It could also be for Cabo Pulmo, hand in hand with CONANP, to see if we can take advantage of this good intention and the technology they bring.”
Earth Army’s co-founder, Miguel Torres, stressed that aerial seeding fills a gap where ground access is difficult. “Many parts of the estuary are swampy or blocked by dense brush. Flying over these zones lets us spread seeds evenly and reach places where people can’t easily walk,” he explained. The seed bombs contain a mix of mangrove, willow, and native hardwood seeds, all treated to resist salt and pests until they sprout.
Environmental groups have welcomed the proposal but urge caution. They note that seed survival depends on rainfall and tidal patterns. To address this, Earth Army plans a follow-up on-ground team to monitor germination rates and carry out supplemental plantings if needed. The municipality also intends to involve local schools in tree-planting workshops, turning the project into a community effort.
Should the Estero Advisory Council approve the project, aerial seeding could begin as early as September—just before the rainy season. Officials hope the first wave of seedlings will take root by November, setting the stage for a larger campaign next year. With mangroves acting as natural flood buffers and fish nurseries, a successful reforestation of the Estero Josefino would strengthen both biodiversity and water security for Los Cabos residents.
As Earth Army awaits the council’s decision, the proposal has already sparked conversation about innovative conservation in Baja California Sur. If carried out, this high-flying method may pave the way for similar projects along Mexico’s coasts—turning a relic of war into a tool for ecological renewal.
