The Rigaud white-tailed deer (Odocoileus virginianus) winter yard is located approximately 100 km west of Montreal, QC. The forest stands attractive for deer in the yard are those provided by white cedars (Thuja occidentalis), an excellent cover for wintering deer in the northeast. Two powerline rights-of-way (120 and 735 kV) bisect cedar stands in the southwest section of the yard. In January 1998 the 120 kV powerline collapsed due to a major ice storm, which deposited more than 50 mm of ice on the structures. The line was rebuilt in the summer and fall of 1998. During and after the reconstruction period we monitored the fate of winter browse in the right-of-way. The objectives of the paper are to discuss the implications of the reconstruction of the 120 kV powerline for deer browse production and to present the 1999 and 2000 browse survey results. In the spring of 1999 it was obvious that no food was yet available to deer in the right-of-way. The 2000 spring survey established the available browse at 16,644 stems/ha and 35,196 twigs/ha. The rate of browsing by deer was 81.0%, which is similar to that of previous winters in that right-of-way.
