Deer/human conflicts have increased due to growing deer populations, limited resources and suburban development in deer habitat. In winter, deer often browse in residential landscapes. This can be reduced by selecting unpalatable plants, protecting woody plants with burlap or trunk protectors, and using deer repellent. In extreme cases, deer can be completely excluded with a fence.
