The uniform spanning forest (USF) in the lattice Z^d, first studied by Pemantle (Ann. Prob. 1991) following a suggestion of R. Lyons, is defined as a limit of uniform spanning trees in growing finite boxes. Although the USF is a limit of trees, it might not be connected- Indeed, Pemantle proved that the USF in Z^d is connected if and only if d8 the USF geometry undergoes a qualitative change...
