Why is daily access to water a critical constraint for the vicuna?
Answer
They must drink fresh water every day to survive
Although the vicuña consumes a diet primarily composed of dry grasses and herbs rather than succulent, moisture-rich plants, it remains biologically dependent on a consistent, daily intake of fresh water. This physiological requirement creates a significant constraint on their habitat selection within the arid and semi-arid altiplano zones. Consequently, their movement patterns and grazing territories are strictly determined by their need to remain within a reasonable distance of reliable water sources.
