Merino and Welsh conjectured that for a 2-edge connected graph G with no loops, the number of spanning trees of G is always less than or equal to either the number of acyclic orientations of G, or the number of totally cyclic orientations of G. In this paper, we prove that the Merino-Welsh conjecture holds for a 3-connected simple graph of minimum degree at least 4 and average degree at least 7.02.
