Axolotls thrive in restored wetlands

_{Editor: Rick van Mechelen}

Axolotls are endemic (which means they are only found here) in the Xochimilco (pronounced as sho-chee-mil-co) lake complex in Mexico. These remarkable species don’t morph from their “larval” stage into their adult forms like other salamanders and can even regrow lost limbs. According to Aztec legends, Xolotl (sho-lo-tl), the god of fire and thunder, turned into a salamander in order to escape sacrifice. While they are popular pets and found in zoos worldwide, their wild population has been under constant pressure, and their population has dropped to an estimated 50 wild individuals.

As part of a research project, eighteen captive-bred axolotls were released into man-made wetlands: one in the canals of Xochimilco, and another in a former quarry. Local farmers and volunteers helped construct natural water filtration systems in these wetlands, resulting in the ideal safe havens for these amphibians.

The released axolotls were equipped with radio trackers, and not only did every single one survive, but many had gained weight, which indicates successful hunting. Some were even found to have formed social bonds with other individuals.

However, the wetlands of Xochimilco are still under threat from pollution and urban expansion. Researchers Dr. Luis Zambrano and Dr. Alejandra Ramos state that restoring the axolotl’s population is a beacon of hope for conservation efforts worldwide. However, this requires commitment and collaboration. Dr. Ramos says that “you don’t need to be a scientist to help. Everybody in the world can make a difference.” Rescuing the axolotl is not just about saving a species, but it’s also about the power of communities, culture, and nature working in harmony.
