Formosan sika deer period with a switch to Japan as the major export market. The intensive hunting of sika during the Dutch era must have severely decreased the population of sika. Sika populations continued to decline over the next few centuries as the human population expanded—the natural habitat of sika in the lowland plains was steadily converted to farmland, and later urbanized, as the human population increased. Hunting also continued. As a result, wild sika populations decreased steadily, and in 1969 the last known wild sika was killed.
