Facts Worth Knowing About Biodiversity in Marieta Islands

Two weeks ago, the National Commission of Natural Protected Areas (CONANP) announced the closure of Playa del Amor—the tucked away beach located in a gaping hole on the surface of one of the Marieta Islands—for an indefinite period of time. The decision was made due the ecological damage present in the coral reef area, resulting from different factors, such as an excessive number of boats anchoring around the reef, the extraction of coral fragments by scuba divers and contamination caused by fuels and oils in the water.

In an interview for Vallarta Opina, the researcher Amilcar Cupul Magaña stated that over the next year, the University of Guadalajara will collaborate with CONANP to study the zone in order to ascertain the current state of the area to determine acceptable visit levels and the recommended measures and restrictions to be adopted. In the meantime, other places in the National Park will remain open to the tourism, including the beach known as Playa de la Nopalera.

Riviera Nayarit’s Conventions and Visitors Bureau, along with other important agencies dedicated to give publicity to the region as one of Mexico’s finest tourism destination, has gone to great lengths to successfully promote Playa del Amor as a one-of-a-kind spot in the entire world. At the same time, being mindful of the importance of preserving the natural balance at this unique location is never a bad idea. Here are some important facts to keep in mind:

Rich in Reef Fish Diversity

Fish species in the Marieta Islands reefs represent the largest biodiversity in Banderas Bay due the variety of habitats in the area. Among the most common species are the Panamic green moray eel (Gymnothorax castaneus), the Mexican goatfish (Mulloidichthys dentatus) and the Blacknosed butterflyfish (Johnrandallia nigrirostris). Furthermore, there are plenty of coral communities that provide haven, breeding and feeding grounds for many organisms.

In total, 12 coral species and 115 fish species live in the sanctuary.

Biosphere Reserve by the UNESCO

In 2008, the United Nations Educational, Scientific and Cultural Organization declared the Marieta Islands a “Biosphere Reserve” as part of the program named “Man and Biosphere”. Since then, the National Park has adopted measures leading to conservation and sustainable development.

It Houses Important Bird Colonies

A wide variety of breeding colonies of bird species gather in the Marietas Islands. It houses 92 bird species, including over 50% of the Bridled tern (Onychoprion anaethetus) community in Mexico and the largest nesting colonies of the Brown booby (Sula leucogaster).

Reproductive Process of the Humpback Whale

It is an important location for the reproductive processes of the Humpback whale (Megaptera novaeangliae), a specie under special protection that visits the Banderas Bay every year in the winter season.

Home of Endangered species

It houses 44 flora and fauna species currently threatened with extinction, including the Olive ridley  (Lepidochelys olivacea) and the Hawksbill sea turtles (Eretmochelys imbricata bissa), the Mexican spiny-tailed iguana (Ctenosaura pectinata) and the Prairie Falcon (Falco mexicanus).

An Important Confluence Zone

The archipelago is located in a zone of confluence with three ocean currents: the California Current, the Costa Rica Coastal Current and the water masses of the Gulf of California. This allows the cohabitation of marine species from the center and south of the Mexican Pacific with those originally from the Gulf of California.

There are still a few days to visit la Playa del Amor in the Marieta Islands. If you don’t want to miss the opportunity to experience this unique spot, remember to follow all the instructions provided by the tour guides. Transportation to the National Park is available by water taxis leaving from Los Muertos Beach in colonia Emiliano Zapata or Punta de Mita, a town located 30 minutes north Puerto Vallarta.
