Sika deer, the graceful spotted deer of Japanese and Chinese art, originally were native to Asia from far-east Russia to Vietnam to the islands of Japan and Taiwan. They are widely raised in captivity to supply velvet antler for traditional medicine. They also were introduced to Europe, North America, and New Zealand, where they compete or interbreed with native deer. Sika deer typically occupy lowland hardwood forests with low winter snow depths, where they thrive in sites disturbed by fire, storm, or logging. In high numbers they can severely impact vegetation though overgrazing, stripping bark from trees and damaging crop fields and forest plantations. Their numbers are high in many parts of Japan, moderate in Russia, and reduced or extinct in the wild in China, Korea, Vietnam, and Taiwan. This book explores their basic biology, behavior, and ecology, including management for sport hunting, conservation or recovery of threatened populations, and resolution of conflict with humans in native and introduced lands.

The expanding distribution of sika and its increase in population in Japan and other countries are causing damage to agriculture and forestry, impacting ecosystems and affecting other species. We are facing conflicting deer issues regarding the conservation of resource values and pest control of sika deer. 

This contributed volume compiles new findings focusing on the ecological plasticity of the sika deer. It aims to clarify the ecological characteristics of the deer by integrating studies of different approaches and provides a perspective for their management. 

The book consists of six parts. Part I introduces the ecological and management background behind the history of sika deer. The following four parts discuss movement ecology (Part II), impact on vegetation and bottom-up effect on sika deer (Part III), impact on ecosystem and its resilience (Part IV), and comparison of life-history characteristics between sika deer and other ungulate species (Part V). The last part (Part VI) covers the science-based management of sika deer. 

Contributed by recognized experts and young researchers of sika deer, this book appeals to researchers and professionals in wildlife biology and wildlife management, evolution, population dynamics, morphology, genetics, and reproductive physiology.
