Cozumel Reef Rest Periods Boost Coral Recovery

COZUMEL, Mexico — The strategy of implementing rest periods for reefs within the Cozumel Reefs National Park (Parque Nacional Arrecifes de Cozumel, or PNAC) has functioned effectively, leading to a greater presence of marine fauna in impacted zones and a reduction in the severity of diseases such as White Syndrome and Bleaching. This is according to data from the National Commission of Natural Protected Areas (Comisión Nacional de Áreas Naturales Protegidas, or CONANP).

The program involves closing specific reef areas to tourism for two-month periods to reduce the presence of boats and tourist activities.

Blanca Alicia Quiroga García, director of CONANP Cozumel, stated that the rest periods for the park's coral reefs have been maintained. The current closure applies to the Colombia Reef—encompassing its shallow, intermediate, and deep sections—as well as Palancar, Caves, and Bricks (Palancar, cuevas y ladrillos). During these two months, access for divers and snorkelers is prohibited, and the general entry of boats is avoided.

Quiroga García said the application of these rest periods has allowed for the presence of more marine fauna, including species that had previously left the reef areas but have now returned. Furthermore, the reefs are no longer experiencing diseases like coral bleaching or White Syndrome.

However, these initial findings are yet to be fully corroborated. The reefs are currently in a monitoring phase. More conclusive results on the state of the coral reefs within the PNAC are expected in 2026, or potentially by the end of 2025.

In the meantime, campaigns to promote care for the protected marine zones continue. Visitors are strongly recommended to avoid using sunscreen or tanning lotions before entering the water to reduce the introduction of foreign substances. The campaigns also aim to prevent poor diving practices, such as cutting pieces of coral, damaging them with fins, or disturbing the sandy seabed.
