Animals are often moved to make way for infrastructure, but we don't know what happens to them next
When major infrastructure projects are built in rural areas, wildlife is often displaced and moved out of the way. This is called mitigation translocation, and it is a globally recognized method for moving animals. However, not everyone applies it the same way, or at all.
