A Rapid Assessment Method for Evaluating Deer Impacts to Forest Vegetation
AVID is a project for Assessing Vegetation Impacts from Deer. Project participants evaluate the impact of deer browsing by tagging and measuring tree seedlings and/or wildflowers. Users of the AVID method can measure the impacts of deer browsing on New York forests, and document this aspect of forest health. Participants will learn forest and woodland ecology, how to identify important spring wildflowers and tree species, and develop an eye for recognizing signs of deer impacts.

These guides describe the procedures to measure vegetation and quantify the impacts deer are having on woodland vegetation. These field methods can be used by volunteers, landowners, land managers, land trusts, foresters, and other natural resource professionals. Individuals can use AVID via a smartphone app for both Apple and Android phones from the Apple App Store or the Google Play Store, or by printing field data sheets and entering the data online at aviddeer.com.
Field data is being collected by individuals and organizations across New York State, and submitted to a central database to track tree, shrub, and wildflower responses to deer browsing over time. Other states have begun to implement the AVID protocol. Knowledge of how deer impacts change through time will help guide deer management decisions at local and regional levels. Participants will document changes in forest plants on their own land, or land in their communities, and will learn:
