GVI working in partnership with Amigos de Sian Kaan (ASK), have been monitoring Mexico’s Caribbean reefs since 2003. Data are collected at Pez Maya (20.00222 degrees N, 87.28624 degrees W) and Punta Gruesa (19.00865 degrees N, 87.58977 degrees W) to support the Mesoamerican Barrier Reef System project and provide information to the National Parks Commission (CONANP). These data are now being used by GVI and its partners to promote the management of the reserve’s resources in a more sustainable manner.


The objective of this monitoring program is the creation of a database that will help to assess the health of the Mexican-Caribbean reefs.

We dive regularly and all incidences of target species are recorded and the global positioning system (GPS) coordinates are known from our monitoring program.
