TheImprovement ofTropical and Subtropical Rangelands

PASTORAL REGIMES OF MAURITANIA 225
southern Mauritania move in a roughly eliptical pattern. Occasionally,
their outward and inward paths cross over each other, but it
is more common for the herds to return to the dry-season wells by
a route different from the one followed when leaving them. This
difference in inbound and outbound routes is not commented upon
in any of the literature, but it may be that the exhaustion of areas
previously grazed during the year makes a selection of an alternative
route desirable.
