I can't identify a wild cherry by looks, but I can identify it by the smell.
Break a fresh limb into 2 pieces & smell it. It will be very noticeable.
Cut that s.o.b. down & scatter all traces of it to hell - the danger to
livestock is when they eat the wilted leaves or bark. Once they wilt,
it releases an acid, prussic acid if I recall correctly, that will kill them
because it turns poisonous.
