 We show that any rotationally symmetric Riemannian manifold has the $L^1$Liouville property for harmonic functions, i.e., any integrable harmonic unction on it must be identically constant. We also give a characterization of a manifold which carries a nonconstant $L^1$ nonnegative subharmonic function.
