Ash rots very quickly here - within months if in ground contact. Good wood for spalting but not for fence posts. Black locust was the preferred wood for fence posts. Very rot resistant and small, weedy trees that aren't good for much else. Mostly replaced by PT now. I have some black locust posts in a split rail fence that have lasted 25 years.
