Fallow deer in historic parks and estates face welfare challenges from chronic stress, disease, and inappropriate management in enclosed populations.
Fallow deer in overcrowded park populations face habitat degradation, increased parasite burdens, and competition for food causing chronic nutritional stress. Animals in enclosed populations cannot escape social stress from dominant individuals. Culling programs in managed parks cause acute suffering if poorly executed. Fallow deer are sensitive to disturbance and parks with high visitor numbers cause chronic vigilance stress in animals unable to achieve normal flight distances. Stag fights during the October rut cause significant injury and occasional death even in managed populations.
