Xochimilco's waterways have been degraded by urbanization — but endure as important sites for recreation, tourism, and wildlife conservation.
On weekends, boat operators (remeros) punt visitors along lake canals in colorfully decorated traditional boats (trajineras).
Some remeros present stories about Mexican history and axolotl conservation in their tours. One study showed this approach improved people's appreciation of axolotls and boosted income for remeros.
