Shrubs are almost always overlooked in wildlife management. They generally get named brush and the process of removal begins. Native shrubs are vital to not only quail but also deer, turkey, rabbits, and other wildlife.
Shrubs not only provide great cover throughout the year, but also provide forage through hard or soft mast production with their fruit or nut production, but they will also provide great browse throughout the year for deer. Consider the attractiveness for loafing shade during the summer and the vertical protection throughout the winter.
