In 1850, Queyras was at its peak with a population of 8,500 inhabitants. Agriculture was present everywhere. Part of the forest has been cleared for pasture or hay fields. This type of agriculture has enabled a particular type of flora to grow. Changing lifestyles, the development of industry in cities, two world wars and changing agricultural practices decimated the population. In 1970, only 1,900 inhabitants still lived in Queyras. The least accessible plots are abandoned and the forest takes over.
