However, it seems the hoped-for preservation strategy did indeed work, according to Wikipedia:

Both under the rule of the Inca and today, vicuñas have been protected by law, but they were heavily hunted in the intervening period. At the time they were declared endangered in 1974, only about 6,000 animals were left. Today, the vicuña population has recovered to about 350,000,[1] and although conservation organizations have reduced its level of threat classification, they still call for active conservation programs to protect populations from poaching, habitat loss, and other threats.
