When someone finds a snake or turtle in a "bad" spot, a common idea is to move it somewhere "better." It feels like helping. Most of the time, it is not, and here is why. Every wild population has its own mix of genes, built up over thousands of years in that exact place. Dropping an outsider into it can quietly mess that up, and it confuses the scientists trying to study the animals. Worse, a moved animal can carry disease. The fungal diseases that are killing snakes and amphibians can hide in an animal that looks perfectly healthy. One carrier released into a healthy population can wipe it out.
