No, the answer is maybe. It depends on the size of the property, what the deer use the property for and how the property is fenced.

1. The larger the property, the less it is affected by the fencing
2. Height of the fencing obviously has an effect...compare a 4 ft fence to an 8 ft fence
3. How deer use the property has a major influence on how the fencing will change their habits. If the property is just a travel route, then they may not come onto the property much at all after fencing it off, especially if it is not a larger property. Deer take the easiest route most of the time, unless they are pressured or they have another reason to come onto the property (food source, bedding area, water, etc.)
