Local hunters had access to a formerly sealed off lucrative Chinese market, and this once again put the region's tiger population at risk of extinction. Numerous publications on these species there are mainly episodic and survey data on this issue are collected by different authors in selected areas which do not give a complete picture of the nature. The reduction of the body weight of today's Siberian tigers may be explained by concurrent causes, namely the reduced abundance of prey because of illegal hunting and that the individuals were usually sick or injured and captured in a conflict situation with people.
