Proposed 237m Dock Threatens Sian Ka’an Mangroves

Tulum, Mexico — A proposal to construct a 237.36-meter-long dock within the mangrove area of the Sian Ka’an Biosphere Reserve has been submitted to Mexico’s Secretariat of Environment and Natural Resources (Semarnat). The project, named "Muelle rústico UHK AAY," was filed by María Frías Campero on October 28, 2024, under a Regional Environmental Impact Assessment (MIA), according to records in Semarnat’s Ecological Gazette.

Project Details and Ecological Concerns

The proposed dock and walkway would occupy an estimated 314.5 square meters in Tulum, within a coastal wetland area characterized by red mangrove (Rhizophora mangle) and black mangrove (Avicennia germinans). These species are protected under Mexican and international environmental regulations due to their critical role in maintaining coastal ecosystems.

The applicant claims the construction will not damage mangrove specimens, stating that the project "does not interfere with the foundation of the works." However, the submission lacks detailed mitigation measures to safeguard the sensitive habitat.

Location in a Protected UNESCO Site

The project falls within the federal boundaries of the Sian Ka’an Biosphere Reserve, designated a UNESCO World Natural Heritage Site in 1987. The reserve is one of Mexico’s most biodiverse regions, where human activities are strictly regulated to preserve its ecosystems.

Semarnat has not yet approved the project, as it remains under evaluation. The agency must consult with the National Commission of Natural Protected Areas (Conanp) and other stakeholders responsible for Sian Ka’an’s conservation.

Rising Pressure for Tourism Development

In recent years, applications for tourism-related infrastructure in high-conservation areas of the reserve have increased. This trend has prompted calls for greater transparency and stricter oversight in environmental assessments, particularly for projects in fragile ecosystems like mangroves.

The outcome of this evaluation will set a precedent for future developments in Mexico’s protected natural areas.
