What official measure in the 1970s was most responsible for the vicuna population recovery?
Answer
A ban on all hunting and strict trade restrictions
Following a period of severe exploitation after the Spanish conquest, which left fewer than 10,000 individuals remaining by the mid-20th century, international and national conservation efforts became critical. Peru and other range countries implemented total bans on hunting and established strict regulations on the commercial trade of vicuna wool starting in the 1970s. These legislative actions allowed the species to rebound significantly and move away from the brink of extinction.
