MND Local: What to know about crocodile, human encounters in Puerta Vallarta

Last week, MND reported on the growing encounters between people and crocodiles in Puerto Vallarta, including the deaths of 11 American crocodiles across the region. The rainy season is active, which is causing rivers to swell, estuaries to fill, and waterways to connect. However, the increase in crocodile sightings isn't evidence of an overpopulation issue.

According to Jalisco’s Ministry of Environment and Territorial Development, there are 300 to 350 crocodiles in the Bahía de Banderas region, encompassing both Jalisco and Nayarit. The rainy season causes crocodiles to move between rivers, estuaries, and the bay, sometimes into areas where people live, work, and play. Development in crocodile habitats has encroached on their natural territories, making coexistence more complicated.

The crocodile population is protected under Mexico’s environmental regulations, and SEMADET has condemned acts of aggression towards them. They are calling for coexistence, not removal or killing of animals. SEMADET is working with authorities, academics, and conservation organizations to improve coexistence through warning signs, monitoring, public education, increased surveillance, and warning flags.

People should avoid approaching, feeding, or trying to chase away crocodiles when encountered, and report sightings to 911 or the Jalisco Alerta app.
