Do native plants improve deer health and growth?

Native Food Sources

Native plants in the Texas Hill Country, such as deer-friendly species of wildflowers, grasses, and shrubs, offer essential nutrients to white-tailed deer. A study by the Texas Parks and Wildlife Department found that white-tailed deer in areas with high native plant cover had higher body weight and growth rates compared to those in areas with low native plant cover. Specifically, deer in areas with 30-50% native plant cover had a 10% increase in body weight compared to those in areas with less than 10% native plant cover.

Shelter and Habitat Complexity

Native plants provide shelter and habitat complexity for white-tailed deer, reducing stress and mortality rates. The dense understory and leaf litter of native plants offer deer protection from harsh weather conditions, predators, and human disturbances. For example, a study in the Hill Country found that deer in areas with high native plant density had a 20% lower mortality rate compared to those in areas with low native plant density.

Soil Nutrient Cycling

Native plants also play a crucial role in soil nutrient cycling, which benefits white-tailed deer health and growth. The roots of native plants help to break down soil nutrients, making them more available to deer. Additionally, native plants like grasses and wildflowers help to prevent soil erosion and retain soil moisture, reducing the need for deer to travel long distances in search of food and water.
