"The species originates from numerous lakes, such as Lake Xochimilco underlying Mexico City... As of 2010, wild axolotls were near extinction due to urbanization in Mexico City and consequent water pollution, as well as the introduction of invasive species such as tilapia and perch... Surveys in 1998, 2003 and 2008 found 6,000, 1,000 and 100 axolotls per square kilometer in its Lake Xochimilco habitat, respectively. A four-month-long search in 2013, however, turned up no surviving individuals in the wild. Just a month later, two wild ones were spotted in a network of canals leading from Xochimilco." [1]

Small cities too. Floodplain management is the farmer, so from 2010: 10.3368/er.28.3.257 (so, _Ecological Restoration_) https://www.researchgate.net/publication/240812159_Creating_...

No idea how long the eggs can aestivate. Nice genetics/biocaching crossover there.

I hoped to see a nationload (MX, BR, something) of LEED living roof that included or adjoined estuary, I guess we know the jaguar (ocelot...) is less a hazard. It just has to be nicer to keep occupied canopy over most of the estuary (so birds don't run off with the cache in minutes) than it is to run ventilation or spend marginal time (¨) on cash crops.
