Wherever deer exist, they will be impacting the ecosystem through browsing. But at what level is that impact considered harmful? Many ecologists consider deer impact harmful when deer begin to reduce plant diversity in a woodland through browsing. knowing the exact number of deer on a property is difficult to measure and unnecessary. There are relatively easy ways to estimate the number of deer on a property or track trends in population sizes over time. This publication is written to help woodland owners better understand how to monitor deer and their impact.

Monitoring deer impact is done by surveying what deer eat in a forest and how intensively they browse those species. Deer are browsers rather than grazers (like bison and cattle), preferring to eat forbs (broadleaf herbaceous plants), vines, shrubs, and trees rather than grasses. Deer also select specific parts of the plants (e.g., leaves, twigs, and young tender growth).

Monitoring Deer Impact Methods:

• Browse Surveys
• Indicator Plants
• Assessing Vegetation Impacts from Deer
• Ten-Tallest Method
• Twig-Aging
• Oak Sentinel
• Stump Sprouts
