Coexisting with Crocodiles in Vallarta

Dr. Pablo Hernández Hurtado, the technical manager of the Cipactli reptile center at the University of Guadalajara’s Coastal University Center, has issued several recommendations for both tourists and residents regarding crocodile preservation and sightings. Dr. Hernández Hurtado explained that crocodiles traverse the entire Puerto Vallarta area, often using the sea as corridors due to the reduction of estuaries caused by urban growth. Sightings are most common near river mouths, such as the Ameca River near the Boca Negra estuary, and in areas like the El Salado estuary. He noted that development since the 1960s, including the construction of the Marina and the airport on former wetlands, has significantly reduced the natural habitat of these reptiles, leading to more frequent encounters in urban and tourist zones.

The movement of crocodiles through urban areas is also influenced by seasonal changes, with increased rainfall facilitating their dispersal towards wetlands and pools. Conversely, during dry periods, crocodiles often need to travel to find new water sources. Dr. Hernández Hurtado stressed that while crocodiles generally avoid human contact and seek self-preservation, they will defend themselves if they feel threatened.

To preserve crocodile habitats, it is crucial to respect the remaining small spaces they inhabit, such as the protected area of the El Salado estuary and the smaller Boca Negra estuary, which supports the healthiest crocodile population and the most nesting sites. Dr. Hernández Hurtado emphasized the need to protect the limited number of breeding females, especially during nesting season, and to avoid approaching nests, as mothers are highly protective and can pose a mortal threat. If encountering a crocodile on the beach, it is important not to swim near it, keep pets and children away, and refrain from touching or provoking the animal. Authorities, such as Civil Protection or 911, who are trained to handle these situations, should be notified immediately.
