Uniform and minimal random spanning trees for finite graphs are well-known objects. Analogues of these for the nearest-neighbor graph on Z d have been studied by Pemantle and Alexander. Here we propose analogous definitions of uniform resp. minimal essential spanning forests for an infinite tree β«,
## Abstract For a graph __G__, we denote by __i__(__G__) the number of isolated vertices of __G__. We prove that for a connected graph __G__ of order at least five, if __i__(__G__β__S__)β<β|__S__| for all β οΈ β __S__ β __V__(__G__), then __G__ has a spanning tree __T__ such that the distance in __T_
