A common question for those in deer-populated areas or cultivating date trees is whether these animals consume dates. Deer are adaptable foragers, and their dietary habits often intersect with human interests, leading to concerns about property and agricultural damage. Understanding their preferences and behaviors is important for managing potential interactions.
Deer’s Attraction to Dates
Deer are attracted to and consume dates, similar to other sweet fruits. Their diet includes a variety of fruits such as apples, pears, persimmons, and plums, which they seek out for their high sugar content. This sweetness provides a quick burst of energy, particularly beneficial during times when other food sources become less abundant, such as in the fall and winter months. Deer are opportunistic feeders, readily consuming fallen fruit from the ground. They may also browse on lower branches, eating new growth and shoots if accessible.
Impact on Deer and Date Trees
While dates offer an energy boost, their consumption can have varied impacts on both deer and the date trees themselves. For deer, an excessive diet of high-sugar foods like dates, which are not a natural part of their primary forage in most environments, can lead to digestive upset or nutritional imbalances. Deer are ruminants with specialized stomach microbes adapted to breaking down high-fiber diets, and large amounts of carbohydrate-rich, low-fiber foods can disrupt this delicate balance. This disruption can cause issues such as acidosis, leading to severe diarrhea and dehydration, which can be harmful or even fatal if not addressed.
Date trees can suffer significant physical damage from deer activity. Deer primarily browse on new shoots, leaves, and tender branches, particularly on younger trees or lower parts of mature trees. This browsing can stunt the growth of young trees or reduce fruit production in more established ones. Male deer also cause damage by rubbing their antlers against tree trunks to remove velvet, which can shred bark and make the trees vulnerable to disease and insect infestations. Such damage can lead to economic losses for date growers and gardeners.
Deterring Deer from Date Trees
Protecting date trees from deer involves implementing various deterrent strategies to make the area less appealing. Physical barriers, such as fencing, are often the most effective long-term solution. Fencing typically requires a height of at least 8 feet, as deer can jump this high. For individual trees, especially young ones, enclosing them with strong wire cylinders can provide protection.
Repellents offer another approach, working by emitting unpleasant smells or tastes that deer dislike. Commercial repellents are available, and natural options include strong-smelling soaps, garlic, or hot pepper solutions, which can be hung from branches or sprayed on plants. However, the effectiveness of repellents can vary, and they may require frequent reapplication, especially after rain or snow. Habitat modification, such as promptly removing fallen fruit, also helps reduce attraction. Scare tactics, like motion-activated sprinklers or noise makers, can provide temporary deterrence, but deer may become accustomed to them over time.
