Resistance of Trees and Shrubs to Deer Damage

News Article

Damage caused by deer browsing on trees and shrubs can be a problem in some rural and suburban areas in Iowa. The amount of damage depends upon seasonal factors, weather conditions, availability of alternative foods, and plant palatability. Prevention of deer browsing is difficult. Home gardeners may be able to avoid some deer damage by careful plant selection. Horticulturists and wildlife specialists at Cornell University in Ithaca, New York, have identified trees and shrubs that are rarely or seldom, occasionally, and frequently damaged by deer. Those plant species adapted to Iowa are listed below.

Home gardeners should realize that no plant species is completely deer resistant. Deer will browse even on the most resistant plants when faced with starvation. However, careful plant selection, along with repellents and fencing can reduce deer damage.
