We have nightshade(no one will touch it), red maple (took out), cherry (took out), buckeye (took most out), Datura or Jimson weed (one goat likes it, so I pull up any I see). We have several species of oak and have not had a problem with them.
My boss insisted on planting holly in the pasture for the wild birds and the berries are toxic so I had to hotwire around those. Cherie Western North Carolina Lilja, Roka (Icelandics)and Tyra (Fjord)
