During two consecutive years, 2+0 bareroot red ash (Fraxinus pennsylvanica Marsh.) seedlings were planted in the spring in clearcuts and in old fields. In the fall of the same years, treeshelters 120 cm in height were installed to protect plants from browsing. Tree growth and survival were assessed over a four-year period following outplanting. Sheltered trees were then significantly higher than the controls, and their root collar diameters were larger, on average. Trees planted on clearcuts were taller than those on old fields. Four years after outplanting, sheltered trees had a slightly better survival rate than the controls with overall survival rate exceeding 97% for both planting years.
