A recent study published on April 30, 2025, in PLOS One offers promising news for axolotl conservation. Researchers in Mexico found that captive-bred axolotls can survive after being released into Lake Xochimilco and artificial wetlands.
The study, led by Alejandra Ramos, highlights the potential for reintroduction programs to aid the recovery of this critically endangered species. Researchers implanted transmitters in 18 captive-bred axolotls, releasing 10 into a restored canal (chinampa) in Lake Xochimilco and eight into a spring-fed pond in an artificial wetland.
All axolotls survived the experiment, with some recaptured individuals gaining weight, indicating successful foraging in their new environments. Ecologist Luis Zambrano emphasizes that while reintroduction is a valuable "Plan B," the primary focus remains improving habitat conditions for wild axolotls. Current efforts include expanding the number of restored chinampas in Lake Xochimilco. These findings suggest that artificial wetlands could also serve as valuable habitats for axolotl conservation.
