What Is the Taiwan Sika Deer?

The Taiwan Sika Deer belongs to the order Artiodactyla and the family Cervidae.

Historically, it inhabited the forests and grasslands of southern Taiwan. Today, reintroduced populations are primarily found in national parks and protected conservation areas.

Adult Taiwan Sika Deer typically measure:

• Body Length: Approximately 140–170 cm (55–67 inches)
• Shoulder Height: Approximately 80–100 cm (31–39 inches)
• Weight: Approximately 50–110 kg (110–243 pounds)
