摘要

The Rigaud white-tailed deer (Odocoileus virginianus) yard is located approximately 100 km westof Montreal, Quebec. The yard is bisected in a north-south axis by a 120 kV transmission powerline built in 1972. The power line collapsed during a major ice storm in January 1998 and wasrebuilt in the summer and fall 1998. In the summer of 1998, a mechanical brush cutting treatmentwas completed and the vegetation was further damaged by construction activities. By October2002 numerous woody stems were taller than 2 m. The vegetation was then treated with hand-held manual brush cutters. During the winter 2003, the right-of-way provided very little browse,but on several occasions, we observed deer browsing in the right-of-way for long periods. Weformulated the hypothesis that deer browsing pressure controlled the residual woody vegetationin the right-of-way. The April 2003 and 2004 browse surveys targeted the stems of three speciessought by deer: red-osier dogwood (Cornus stolonifera), American ash (Fraxinus americana) andwillows (Salix spp.). We sampled over 200 stems of each species each spring. All these residualstems were short and most were missed during the October 2002 treatment. Browsing rates onC. stolonifera, Salix spp. and F. americana were respectively 97.3%, 97.3% and 84.9% in 2003, and96.3%, 97.3% and 89.2% in 2004. These very high browsing rates indicate that when stems areshort and deer density is high, deer can exert a certain control of the woody vegetation in a right-of-way in a deer yard, at least during the first winters following a vegetation control treatment.

Americana分别为97.3％，97.3％和84.9％，2004年96.3％，97.3％和89.2％。这些非常高的浏览率表明，当茎艺术和鹿密度高时，鹿可以施加鹿在鹿院内以鹿院的右路进行一定控制木质植被，至少在植被控制治疗后的第一冬季。
