Popis: Known populations (0, 269, 538, and 1075/ha) of pine voles (Microtus pinetorum LeConte) were maintained in wire mesh-enclosed blocks of ‘McIntosh’/M26 apple trees (Malus domestica Borkh.) for 2 years. There was little effect of the voles the 1st year, but the 2nd year the highest population was associated with the death of one tree; severe reductions in growth, yield, and fruit size; and a dramatic reduction in the value of the crop. Neither the low nor the medium population affected yield significantly, but there was a reduction in vegetative growth in the medium population plot in the 2nd year.
