Final answer:
The ideal height of a fence to prevent deer from jumping over is 8 feet, but 6 feet may also be effective depending on the species and context.
Step-by-step explanation:
The ideal height of a fence to prevent deer from jumping over depends on several factors, including the species of deer and the context of the fence. In general, a fence height of 8 feet is considered sufficient to deter most deer species from jumping over. However, in some cases, a 6-foot fence may also be effective.
It's important to note that deer are agile jumpers and can clear significant heights when motivated. Therefore, other measures such as adding barriers or angled fencing may be necessary to create a more secure enclosure.
