We consider the time for extinction for a contact process on a tree of bounded degree as the number of vertices tends to infinity. We show that
uniformly over all such trees the extinction time tends to infinity as the
exponential of the number of vertices if the infection parameter is strictly above the critical value for the one dimensional contact process.
An application to the contact process on NSW graphs is given.
