Let G be a graph with n vertices. Suppose that there are k edge-disjoint spanning trees in G. We show that if the minimum degree of the vertices in G is at least kl, then there are k edge-disjoint spanning trees rooted at any vertex with depth O(n/l) in G.Also, we show that given a graph, a vertex r of the graph, and a positive integer k, the problem of finding k edge-disjoint spanning trees rooted at r with optimal depth is NP-hard.
