Abstract: 
It is known that free actions of virtually free groups are treeable. We prove an analoguous results for locally finite Borel graphs G: if every G component is quasi-isometric to a tree, then the equivalence relation is treeable, under the conditions that the G-components be one-ended or have bounded degree.
