When do baby squirrels leave their nest Is it safe to take the tree down then?

Baby squirrels typically leave their nest around 10 to 12 weeks of age, but this can vary depending on the species and environmental factors. It's best to wait until late summer or early fall, after the young have fledged, before taking down a tree with an active nest. Removing the tree while the young are still present can disrupt their development and survival. Always check for signs of active nests before proceeding with tree removal.
