Biologists note that pregnant does are good mothers, and they sense when to move out of a flood zone. The primary concern for deer populations is for stressed does that are dropping or dropped fawns in areas of rising water levels, and the fawns were too young to move to higher ground.
This is surely the case in some flood-ravaged areas.
“We know it’s going to have a negative impact,” said William McKinley, Mississippi Department of Wildlife, Fisheries, and Parks Deer Program coordinator. “Let’s just say that up front.”
But fawn survival in flood plains is typically high, even during flood years.
“A reduced fawn crop (in the Mississippi Delta) is what I expect to see,” said McKinley. How much? We have to wait and see.”
